4. Use the theorems for interior and exterior angles of a polygon to find:

d. The interior angle of a regular 44-gon.

e. The number of sides in a regular polygon with an interior angle is 175°.

f. The exterior angle in a regular hexagon.

Answers

Answer:

d)  171.8°

e)  72

f)  60°

Step-by-step explanation:

Part d

The Polygon Interior Angle Theorem states that measure of the interior angle of a regular polygon with n sides is [(n - 2) · 180°] / 2.

The number of sides of a 44-gon is n = 44. Therefore, the measure of its interior angle is:

[tex]\begin{aligned}\textsf{Interior angles of a 44-agon}&=\dfrac{(44-2) \cdot 180^{\circ}}{44}\\\\&=\dfrac{42\cdot 180^{\circ}}{44}\\\\&=\dfrac{7560^{\circ}}{44}\\\\&=171.8^{\circ}\;\sf(nearest\;tenth)\end{aligned}[/tex]

Therefore, the interior angle of a 44-gon is 171.8°.

[tex]\hrulefill[/tex]

Part e

The Polygon Interior Angle Theorem states that measure of the interior angle of a regular polygon with n sides is [(n - 2) · 180°] / 2.

Given the interior angle of a regular polygon is 175°, then:

[tex]\begin{aligned} \textsf{Interior angle}&=175^{\circ}\\\\\implies \dfrac{(n-2) \cdot 180^{\circ}}{n}&=175^{\circ}\\\\(n-2)\cdot 180^{\circ}&=175^{\circ}n\\\\180^{\circ}n-360^{\circ}&=175^{\circ}n\\\\5^{\circ}n&=360^{\circ}\\\\n&=72\end{aligned}[/tex]

Therefore, the number of sides of the regular polygon is 72.

[tex]\hrulefill[/tex]

Part f

According the the Polygon Exterior Angles Theorem, the sum of the measures of the exterior angles of a polygon is 360°.

Therefore, to find exterior angle of a regular hexagon, divide 360° by the number of sides:

[tex]\begin{aligned}\sf Exterior\;angle&=\dfrac{360^{\circ}}{\sf Number\;of\;sides}\\\\&=\dfrac{360^{\circ}}{6}\\\\&=60^{\circ}\end{aligned}[/tex]

Therefore, the exterior angle of a regular hexagon is 60°.

Answer:

4. a. 171.818°

b. 72 sides

c. 60°

Step-by-step explanation:

d. The interior angle of a regular polygon with n sides can be calculated using the formula:

[tex]\bold{Interior Angle =\frac{ (n-2) * 180\°}{n}}[/tex]

For a regular 44-gon, the interior angle would be:

[tex]\bold{Interior Angle =\frac{ (44-2) * 180\°}{44}=171.818^o}[/tex]

[tex]\hrulefill[/tex]

e. The number of sides in a regular polygon with an interior angle of 175° can be found using the formula:

[tex]\bold{n = \frac{360\° }{180\° - Interior \:Angle}}[/tex]

For an interior angle of 175°, the number of sides would be:

substituting Value,

[tex]\bold{n =\frac{ 360\° }{ 180\° - 175\°} = \frac{360\° }{ 5\° }= 72 \:sides}[/tex]

[tex]\hrulefill[/tex]

f.

The sum of the exterior angles of any polygon is always 360°.

Since a regular hexagon has six sides,
n=6

exterior angle would be [tex]\bold{\frac{360\° }{ n}}[/tex]

substituting value,

exterior angle=[tex]\bold{\frac{360\° }{ 6}=60\°}[/tex]

Find the difference by subtracting the second polynomial from the first.(11m^(2)n^(5)-3m^(2)n^(3)+5mn-n ) and (-6m^(2)n^(5)+3m^(2)n^(5)+m+2n )

Answers

The difference between the two polynomials is 5m^(2)n^(5) - 3m^(2)n^(3) + 5mn + m + n.

To subtract the second polynomial from the first polynomial, we need to perform term-wise subtraction. Let's break down the process step by step:

The first polynomial is: 11m^(2)n^(5) - 3m^(2)n^(3) + 5mn - n.

The second polynomial is: -6m^(2)n^(5) + 3m^(2)n^(5) + m + 2n.

To subtract the second polynomial from the first, we need to change the signs of all terms in the second polynomial and then combine like terms.

First, let's change the signs of the terms in the second polynomial:

-(-6m^(2)n^(5) + 3m^(2)n^(5) + m + 2n) = 6m^(2)n^(5) - 3m^(2)n^(5) - m - 2n.

Now, we can combine like terms by adding or subtracting coefficients of similar monomials:

(11m^(2)n^(5) - 3m^(2)n^(3) + 5mn - n) - (6m^(2)n^(5) - 3m^(2)n^(5) - m - 2n)

= 11m^(2)n^(5) - 3m^(2)n^(3) + 5mn - n - 6m^(2)n^(5) + 3m^(2)n^(5) + m + 2n

= (11m^(2)n^(5) - 6m^(2)n^(5)) + (-3m^(2)n^(3) + 3m^(2)n^(5)) + (5mn + m) + (-n + 2n)

= 5m^(2)n^(5) - 3m^(2)n^(3) + 5mn + m + n.

Therefore, the difference between the two polynomials is 5m^(2)n^(5) - 3m^(2)n^(3) + 5mn + m + n.

In summary, to find the difference, we changed the signs of all terms in the second polynomial and then combined like terms with the first polynomial. The resulting polynomial is the difference between the two original polynomials.

+_____ (poss. answers- 1.75, 0.25, 2, 2.25)

Answers

Answer:

h(t) = 1.75 cos (π/6) + 2.25

Step-by-step explanation:

the amplitude of a regular cos graph is 1 (it alternates between +1 and -1 on the y-axis). that is, amplitude =  (1 - -1)/2 = 2/2 = 1.

this graph has amplitude (4 - 0.5)/2 = 3.5/2 = 1.75.

the graph repeats for every sixth value on the x-axis (time axis).

in the x-axis direction, a cos graph that becomes 6 times larger is cos (π/6). a cos graph that becomes 6 times smaller is cos (6π).

so for our graph, it is cos (π/6).

what about the y-shift?

the graph has already been enlarged 1.75 times parallel to the y-axis.

it crosses the y-axis at 4. so the y-shift is 4 - 1.75 = 2.25.

so our graph is given by h(t) = 1.75 cos (π/6) + 2.25

Answer: got it right

h(t)=1.75, cos(1/3), + 2.25

Simplify the following expression:
(8t − 6t2) + 14(3t + 4)
After simplifying, what number is multiplied by the t?

Answers

We can see that the number multiplied by t is 50. Therefore, the simplified expression is -6t^2 + 50t + 56, and the number multiplied by t is 50.

To simplify the given expression (8t - 6t^2) + 14(3t + 4), we first need to apply the distributive property by multiplying 14 with both terms inside the parentheses. This gives us:
8t - 6t^2 + 42t + 56
Now, we can combine like terms by adding the coefficients of the t and t^2 terms. The t^2 term has a coefficient of -6, and there are no other t^2 terms in the expression, so we can just bring it down as it is. The t term has a coefficient of 8 + 42 = 50, so we can simplify the expression further as:
-6t^2 + 50t + 56
From this expression, we can see that the number multiplied by t is 50. Therefore, the simplified expression is -6t^2 + 50t + 56, and the number multiplied by t is 50.

Last year, 5 friends went to the beach. They each drank the same number of canned drinks and had 2 drinks left over. 2 friends could not come to the beach this year. The others brought the same number of drinks as last year and each drank equally as much as the year prior, this time ending with 8 drinks left over. How many beverages did each friend drink?

Answers

Each friend drank a total of 3 beverages during their visit to the beach.

Numerical calculation

To find the number of beverages each friend drank, let's assume the number of drinks they brought and consumed this year is represented by 'x'.

From the given information, we can set up the following equations:

Last year:

5x + 2 = Total number of drinks (equation 1)

This year:

3x + 8 = Total number of drinks (equation 2)

Since the total number of drinks should be the same in both years, we can set equation 1 equal to equation 2:

5x + 2 = 3x + 8

Now, let's solve this equation to find the value of 'x':

5x - 3x = 8 - 2

2x = 6

x = 3

So, each friend drank 3 canned drinks both last year and this year.

Therefore, each friend drank 3 beverages.

Answers

Answer:

x = 9 and y = 4

Step-by-step explanation:

-2x + 7y = 10    (call this equation '1')

x - 3y = -3      (call this '2')

multiply '2' by 2:

2x - 6y = -6  (call this '3')

add '1' and '3':

(-2x + 7y = 10)  +  (2x - 6y = -6)

0x + y = 4

y = 4

sub that back into '1':

-2x + 7y = 10

-2x + 7(4) = 10

-2x + 28 = 10

-2x = 10 - 28 = -18

x = -18/-2 = 9

sub both y = 4 and x =9 into '2' to check if everything adds up:

x - 3y = -3

9 - 3(4) = 9 - 12 = -3

so x = 9 and y = 4

The cash cycle, also known as the operating cycle or cash conversion cycle, is a financial metric that measures the time it takes for a company to convert its investments in inventory and other resources into cash flow from sales. It provides insight into the efficiency of a company's working capital management.

The cash cycle can be calculated using the following formula:

Cash Cycle = Inventory Conversion Period + Receivables Conversion Period - Payables Conversion Period

1. Inventory Conversion Period (ICP):

ICP measures the average number of days it takes for the company to convert its raw materials into finished goods. It is calculated as:

ICP = (Average Inventory / Cost of Goods Sold) x Number of Days in a Year

Average Inventory = (Opening Inventory + Closing Inventory) / 2

Cost of Goods Sold = Total Sales - Closing Inventory

2. Receivables Conversion Period (RCP):

RCP measures the average number of days it takes for the company to collect payment from its customers. It is calculated as:

RCP = (Average Receivables / Total Sales) x Number of Days in a Year

Average Receivables = (Opening Receivables + Closing Receivables) / 2

Opening Receivables = Total Sales x Percentage of Sales on Credit

Closing Receivables = Total Sales x Percentage of Sales on Credit - Collections

3. Payables Conversion Period (PCP):

PCP measures the average number of days it takes for the company to pay its suppliers. It is calculated as:

PCP = (Average Payables / Total Purchases) x Number of Days in a Year

Average Payables = (Opening Payables + Closing Payables) / 2

Opening Payables = Total Purchases x Percentage of Purchases on Credit

Closing Payables = Total Purchases x Percentage of Purchases on Credit - Payments

Now, let's calculate the cash cycle using the provided information:

Given data:

Opening balances:

Raw material: ₹1,00,000

WIP: ₹45,000

Finished goods: ₹1,35,000

Debtors: ₹6,00,000

Creditors: ₹8,60,000

Closing balances:

Raw material: ₹2,00,000

WIP: ₹65,000

Finished goods: ₹1,25,000

Debtors: ₹5,45,000

Creditors: ₹9,75,000

Costs incurred during the year:

Manufacturing costs: ₹11,60,000

Excise duty: ₹18,80,000

Selling and distribution expenses: ₹6,20,000

Admin. overheads: ₹2,00,000

Total sales: ₹2,01,96,800

Total purchases: ₹1,46,00,000

Percentage of sales on credit: 40%

Percentage of purchases on credit: 70%

1. Calculate the Inventory Conversion Period (ICP):

Average Inventory = (Opening Inventory + Closing Inventory) / 2

Opening Inventory = Raw Material + WIP + Finished Goods

Closing Inventory = Raw Material + WIP + Finished Goods

Opening Inventory = ₹1,00,000 + ₹45,000 + ₹1,35,000 = ₹2,80,000

Closing Inventory = ₹2,00,000 + ₹65,000 + ₹1,25,000 = ₹3,90,000

Average Inventory = (₹2,80,000 + ₹3,90,000) / 2 = ₹3,35,000

Cost of Goods Sold = Total Sales - Closing Inventory

Cost of Goods Sold = ₹2,01,96,800 -

The coordinates of midpoint P are P(-1/2, 3/2) and coordinates of midpoint Q are Q(-3/2, -4).

To find the coordinates of the midpoints P and Q of sides AB and AC, we can use the midpoint formula.

The midpoint formula states that the coordinates of the midpoint of a line segment between two points (x1, y1) and (x2, y2) are given by:

Midpoint = ((x1 + x2) / 2, (y1 + y2) / 2)

Using this formula, we can find the coordinates of P and Q as follows:

Coordinates of midpoint P:

P = ((2 + (-3)) / 2, (-1 + 4) / 2)

= (-1/2, 3/2)

The radius 5cm, of a sphere increases at the rate of 0.4 cm/s. At what rate will the area be increasing?
a) 40 pi cm^2/s b) 24 pi cm^s/ s c) 16 pi cm^2/ s d) 10 pi cm^2/ s

Answers

The rate at which the surface area of the sphere is increasing is 16π cm^2/s.(option-c)

To find the rate at which the area of a sphere increases when its radius is increasing at a given rate, we can use the formula for the surface area of a sphere, which is A =[tex]4πr^2[/tex], where r is the radius of the sphere and A is its surface area. We can then differentiate this with respect to time t to find the rate of change of area with respect to time, which is given as dA/dt.

Given that the radius of the sphere increases at the rate of 0.4 cm/s, we can find the rate of change of area as follows:

- Differentiate the surface area formula with respect to time t:

dA/dt = d/dt [tex](4πr^2)[/tex]

- Use the chain rule to differentiate[tex]r^2[/tex]with respect to time t:

d/dt (r^2) = 2r (dr/dt)

- Substitute the value of dr/dt given as 0.4 cm/s, and the radius value as 5 cm:

dA/dt = 4π(5)^2 (2 × 0.4)

- Simplify the expression to get the rate of change of area with respect to time:

dA/dt = 16π [tex]cm^2/s[/tex]

Austin, Texas has a statue of Stevie Ray Vaughn that is 12 feet tall. It cast an 8 ft shadow. Doug stops to admire the statue. Doug's shadow is 3.5 ft. How tall is Doug?

Answers

Answer:

5.25 feet tall

Step-by-step explanation:

Doug's height / Doug's shadow = Statue's height / Statue's shadow

x / 3.5 = 12 / 8

Cross-multiplying:

8x = 3.5 * 12

8x = 42

Dividing both sides by 8:

x = 42 / 8

x ≈ 5.25

Answers

The simplified form of (5m² - 3)² is 25m⁴ - 30m² + 9.

Given is an expression (5m² - 3)², we need to simplify the expression,

To multiply the expression (5m² - 3)², we can use the formula for squaring a binomial:

(a - b)² = a² - 2ab + b²

In this case, a = 5m² and b = 3.

Substituting these values into the formula, we get:

(5m² - 3)² = (5m²)² - 2(5m²)(3) + (3)²

= 25m⁴ - 30m² + 9

Therefore, the simplified form of (5m² - 3)² is 25m⁴ - 30m² + 9.

4(-2)² + 8(-2) + 3(-2) + 6 = ? Can you break down how you solved it

Answers

Answer:

Step-by-step explanation:

To solve the expression 4(-2)² + 8(-2) + 3(-2) + 6, we need to follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division - from left to right, Addition and Subtraction - from left to right).

First, we will simplify any calculations within parentheses:

4(-2)² + 8(-2) + 3(-2) + 6

(-2)² is equal to (-2) * (-2), which is 4:

4 * 4 + 8(-2) + 3(-2) + 6

Next, we perform the multiplication:

4 * 4 = 16

Now, we have:

16 + 8(-2) + 3(-2) + 6

Next, we continue with the multiplication:

8(-2) = -16

3(-2) = -6

Now, we have:

16 + (-16) + (-6) + 6

Finally, we simplify the addition and subtraction from left to right:

16 + (-16) = 0

0 + (-6) = -6

-6 + 6 = 0

Therefore, the expression 4(-2)² + 8(-2) + 3(-2) + 6 simplifies to 0.

A shop has jars of strawberry jam and raspberry jam in the ratio 3:1
Two customers come into the shop and randomly select a jar of jam
to purchase.

The probability that both customers select strawberry jam is 11/20

a) How many jars of jam does the shop have initially?

b) Given that the customers both chose the same type of jam, work
out the probability that they both chose strawberry.

Answers

The shop initially has 0.884 jars of jam

The probability that both customers chose strawberry jam, is 0.25.

a) Let's assume the number of jars of strawberry jam is 3x and the number of jars of raspberry jam is x.

So, the total number of jars of jam in the shop is 3x + x = 4x.

According to the given information, the probability that both customers select strawberry jam is 11/20.

So, the probability of the first customer selecting a jar of strawberry jam = (3x/4x) = 3/4,

and the probability of the second customer

=  ((3x-1)/(4x-1)).

Now, (3/4) ((3x-1)/(4x-1)) = 11/20

(3/4) ((3x-1)/(4x-1)) = 11/20

20(3/4) ((3x-1)/(4x-1)) = 11

15 (3x-1) = 44  (4x-1)

45x - 15 = 176x - 44

176x - 45x = 44 - 15

131x = 29

x ≈ 29/131

Therefore, the value of x is 0.221

To find the initial number of jars of jam in the shop, we can substitute this value of x into the equation:

4x =  0.884

b) The probability of the first customer selecting strawberry jam is

= (3x)/(4x)

= 3/4.

Therefore, the probability that both customers chose strawberry jam is:

= (3/4) x ((3x-1)/(4x-1))

= (3/4)  ((3 x 0.221 - 1)/(4 x 0.221 - 1))

= (3/4) ((3 x 0.221 - 1)/(4 x 0.221 - 1))

≈ 0.25

Step-by-step explanation:

Given midsegment EF = (4x+6) and base segment BC = (9x+4) of a trapezoid with base AD = 3, you want the value of x and the lengths of the two segments EF and BC.

Midsegment

The midsegment parallel to the base segment is the average of the lengths of the parallel bases.

  4x +6 = 1/2((9x +4) +3))

  8x +12 = 9x +7 . . . . . . . . . multiply by 2 and simplify

In a sample of 560 adults, 336 had children. Construct a 95% confidence interval for the true population proportion of adults with children.

Give your answers as decimals, to three places

< p <










What is the expected value of �?

Answers

The confidence interval is 0.559 < p < 0.641 and expected value is 0.600

Confidence Interval

To construct a confidence interval for the true population proportion, we can use the formula:

p ± Z * √((p × (1 - p)) / n)

Where:

p = sample proportion (336/560)

Z = critical value for the desired confidence level

95% confidence = Z-value of approximately 1.96

n = 560

Let's calculate the confidence interval:

p = 336/560 ≈ 0.600

Z ≈ 1.96 (for a 95% confidence level)

n = 560

Plugging these values into the formula:

p ± Z × √((p × (1 - p)) / n)

0.600 ± 1.96 × √((0.600 × (1 - 0.600)) / 560)

0.600 ± 1.96 × √((0.240) / 560)

0.600 ± 1.96 × √(0.0004285714)

0.600 ± 1.96 × 0.020709611

0.600 ± 0.040564459

The confidence interval is:

0.559 < p < 0.641

Therefore, the 95% confidence interval for the true population proportion of adults with children is 0.559 < p < 0.641.

The expected value

For proportions, the expected value is simply the sample proportion, which is approximately 0.600.
