x = 28.3 degree

We have to given that;

In a triangle,

Two angles are, 61.7 degree and 90 degree

And, One side is, 14.76.

Now, We can formulate;

sin 61.7° = Perpendicular / Hypotenuse

sin 61.7° = z / 14.76

0.88 = z / 14.76

z = 0.88 x 14.76

z = 12.99

And, By Pythagoras theorem we get;

14.76² = z² + y²

14.76² = 12.99² + y²

217.85 = 168.74 + y²

y² = 217.85 - 168.74

y² = 49.1

y = 7.01

And, By sum of all the angles in triangle, we get;

x + 61.7 + 90 = 180

Option A is correct, the sequence is a geometric and common ratio is 2/3.

To determine whether the given sequence is geometric, we need to check if there is a common ratio between consecutive terms.

Let's examine the given sequence:

1/3, 2/9, 4/27, 8/81, 16/243...

To find the ratio between consecutive terms, we can divide each term by its preceding term:

(2/9)/(1/3) = 2/9 × 3/1 = 2/3

(4/27)/(2/9) = 4/27 × 9/2 = 4/6 = 2/3

(8/81)/(4/27) = 8/81 × 27/4 = 2/3

(16/243)/(8/81) = 16/243 × 81/8 = 2/3

As we can see, there is a common ratio of 2/3 between consecutive terms.

Therefore, the given sequence is indeed geometric.

Answer:

The inverse function is:

f(x)=√x−2

Step-by-step explanation:

To find the inverse function of y=f(x) you have to transform the formula to calculate x in terms of y.

y=x2+2

x2=y−2

x=√y−2

Now we can change the letters to follow the convention that x is the independent variable and y is the function's value:

y=√x−2

You have to calculate the domain of the result function.

Here you have the expression under square root sign, so the domain is the set where x−2≥0

x−2≥0⇒x≥2

The coordinate of point X" after translating segment XY along the vector <-3, 1> and then rotating it 90 degrees is X" (4, 5).

To find the coordinate of point X" after translating segment XY along the vector <-3, 1> and then rotating it 90 degrees, we need to follow these steps:

Translation: Add the components of the translation vector <-3, 1> to the coordinates of point X(-2, 3) to get the new coordinates of X'.

X' = (-2 + (-3), 3 + 1) = (-5, 4)

Now, we have the translated endpoint X'.

Rotation: To rotate the point X' by 90 degrees, we need to swap the x and y coordinates and negate the new x coordinate.

X" = (y-coordinate of X', -x-coordinate of X')

X" = (4, -(-5))

X" = (4, 5)

Therefore, the coordinate of point X" after translating segment XY along the vector <-3, 1> and then rotating it 90 degrees is X" (4, 5).

In summary, we first translate point X(-2, 3) along the vector <-3, 1> to get X' (-5, 4). Then, we rotate X' by 90 degrees to obtain X" (4, 5).

a) Over 16.8 pounds: 4.85%.

b) Under 13.8 pounds: 73.24%.

c) Between 13.8 and 16.8 pounds: 21.91%.

We first must use the z-score formula, as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In which:

The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, and can be positive(above the mean) or negative(below the mean).

The z-score table is used to obtain the p-value of the z-score, and it represents the percentile of the measure represented by X in the distribution.

The mean and the standard deviation for this problem are given as follows:

[tex]\mu = 12, \sigma = 2.9[/tex]

Item a:

The proportion is one subtracted by the p-value of Z when X = 16.8, hence:

Z = (16.8 - 12)/2.9

Z = 1.66.

Z = 1.66 has a p-value of 0.9515.

1 - 0.9515 = 0.0485, hence the percentage is of 4.85%.

Z = (13.8 - 12)/2.9

Z = 0.62.

Z = 0.62 has a p-value of 0.7324.

Item c:

The width of the vegetable garden is 8 feet.

To determine the width of the vegetable garden.

Given information:

Flower garden length = 6 feet

Flower garden width = 4 feet

Vegetable garden length = Flower garden length

Area of the flower garden = half the area of the vegetable garden

To find the width of the vegetable garden, we need to find the area of both gardens.

Area of the flower garden = length × width

Area of the flower garden = 6 feet × 4 feet

Area of the flower garden = 24 square feet

Since the area of the flower garden is half the area of the vegetable garden, we can set up the following equation:

24 square feet = (1/2) × Area of the vegetable garden

To solve for the area of the vegetable garden, we multiply both sides of the equation by 2:

2 × 24 square feet = Area of the vegetable garden

48 square feet = Area of the vegetable garden

Now that we know the area of the vegetable garden is 48 square feet, we can find the width.

Area of the vegetable garden = length × width

48 square feet = 6 feet × width

To solve for the width of the vegetable garden, we divide both sides of the equation by 6:

48 square feet / 6 feet = width

8 feet = width

Therefore, the width of the vegetable garden is 8 feet.

Step-by-step explanation:

You want the piecewise function that gives straight line segments between domain boundary points (-8, 5), (-2, -9), (1, -2), (8, 4).

The two-point equation for the slope of a line is ...

  m = (y2 -y1)/(x2 -x1)

For the first pair of points, the slope is ...

  m = (-9 -5)/(-2 -(-8)) = -14/6 = -7/3

The attached calculator image shows the computation of slope for the other two segments. Those slopes are 7/3 and 6/7.

The slope-intercept form of the equation for a line can be rearranged to give the y-intercept:

  y = mx + b

  b = y - mx

In the attached, we used the (x1, y1) point for each segment. For the first segment, the y-intercept is ...

To find the area of a regular polygon, we can use the following formula:

[tex]\boxed{\begin{minipage}{5.5cm}\underline{Area of a regular polygon}\\\\$A=\dfrac{s^2n}{4 \tan\left(\dfrac{180^{\circ}}{n}\right)}$\\\\\\where:\\\phantom{ww}$\bullet$ $n$ is the number of sides.\\ \phantom{ww}$\bullet$ $s$ is the side length.\\\end{minipage}}[/tex]

Given the polygon is an octagon, n = 8.

Given each side measures 12 m, s = 12.

Substitute the values of n and s into the formula for area and solve for A:

[tex]\implies A=\dfrac{(12)^2 \cdot 8}{4 \tan\left(\dfrac{180^{\circ}}{8}\right)}[/tex]

[tex]\implies A=\dfrac{144 \cdot 8}{4 \tan\left(22.5^{\circ}\right)}[/tex]

[tex]\implies A=\dfrac{1152}{4 \tan\left(22.5^{\circ}\right)}[/tex]

[tex]\implies A=\dfrac{288}{\tan\left(22.5^{\circ}\right)}[/tex]

[tex]\implies A=695.29350...[/tex]

Therefore, the area of a regular octagon with side length 12 m is 695.3 m² rounded to the nearest tenth.

[tex]\hrulefill[/tex]

The sum of an interior angle of a regular polygon and its corresponding exterior angle is always 180°.

If the exterior angle of a polygon measures 40°, then its interior angle measures 140°.

To determine the number of sides of the regular polygon given its interior angle, we can use this formula, where n is the number of sides:

[tex]\boxed{\textsf{Interior angle of a regular polygon} = \dfrac{180^{\circ}(n-2)}{n}}[/tex]

Therefore:

[tex]\implies 140^{\circ}=\dfrac{180^{\circ}(n-2)}{n}[/tex]

[tex]\implies 140^{\circ}n=180^{\circ}n - 360^{\circ}[/tex]

[tex]\implies 40^{\circ}n=360^{\circ}[/tex]

[tex]\implies n=\dfrac{360^{\circ}}{40^{\circ}}[/tex]

[tex]\implies n=9[/tex]

Therefore, the regular polygon has 9 sides.

To determine the length of each side, divide the given perimeter by the number of sides:

[tex]\implies \sf Side\;length=\dfrac{Perimeter}{\textsf{$n$}}[/tex]

[tex]\implies \sf Side \;length=\dfrac{72}{9}[/tex]

[tex]\implies \sf Side \;length=8\;ft[/tex]

Therefore, the length of each side of the regular polygon is 8 ft.

[tex]\hrulefill[/tex]

The area of a regular polygon can be calculated using the following formula:

[tex]\boxed{\begin{minipage}{5.5cm}\underline{Area of a regular polygon}\\\\$A=\dfrac{s^2n}{4 \tan\left(\dfrac{180^{\circ}}{n}\right)}$\\\\\\where:\\\phantom{ww}$\bullet$ $n$ is the number of sides.\\ \phantom{ww}$\bullet$ $s$ is the side length.\\\end{minipage}}[/tex]

A regular pentagon has 5 sides, so n = 5.

If its perimeter is 50 inches, then the length of one side is 10 inches, so s = 10.

Substitute the values of s and n into the formula and solve for A:

[tex]\implies A=\dfrac{(10)^2 \cdot 5}{4 \tan\left(\dfrac{180^{\circ}}{5}\right)}[/tex]

[tex]\implies A=\dfrac{100 \cdot 5}{4 \tan\left(36^{\circ}\right)}[/tex]

[tex]\implies A=\dfrac{500}{4 \tan\left(36^{\circ}\right)}[/tex]

[tex]\implies A=\dfrac{125}{\tan\left(36^{\circ}\right)}[/tex]

[tex]\implies A=172.047740...[/tex]

Therefore, the area of a regular pentagon with perimeter 50 inches is 172.0 in² rounded to the nearest tenth.

Answer:

1.695.29 m^2

2.8 feet

3. 172.0477 in^2

Step-by-step explanation:

1. The area of a regular octagon can be found using the formula:

[tex]\boxed{\bold{Area = 2a^2(1 + \sqrt{2})}}[/tex]

where a is the length of one side of the octagon.

In this case, a = 12 m, so the area is:

[tex]\bold{Area = 2(12 m)^2(1 + \sqrt{2}) = 288m^2(1 + \sqrt2)=695.29 m^2}[/tex]

Therefore, the Area of a regular octagon is 695.29 m^2

2.

The formula for the exterior angle of a regular polygon is:

[tex]\boxed{\bold{Exterior \:angle = \frac{360^o}{n}}}[/tex]

where n is the number of sides in the polygon.

In this case, the exterior angle is 40°, so we can set up the following equation:

[tex]\bold{40^o=\frac{ 360^0 }{n}}[/tex]

[tex]n=\frac{360}{40}=9[/tex]

Therefore, the polygon has n=9 sides.

Perimeter=72ft.

We have

[tex]\boxed{\bold{Perimeter = n*s}}[/tex]

where n is the number of sides in the polygon and s is the length of one side.

Substituting Value.

72 feet = 9*s

[tex]\bold{s =\frac{ 72 \:feet }{ 9}}[/tex]

s = 8 feet

Therefore, the length of each side of the polygon is 8 feet.

3.

Solution:

A regular pentagon has five sides of equal length. If the perimeter of the pentagon is 50 in, then each side has a length = [tex]\bold{\frac{perimeter}{n}=\frac{50}{5 }= 10 in.}[/tex]

The area of a regular pentagon can be found using the following formula:

[tex]\boxed{\bold{Area = \frac{1}{4}\sqrt{5(5+2\sqrt{5})} *s^2}}[/tex]

where s is the length of one side of the Pentagon.

In this case, s = 10 in, so the area is:

[tex]\bold{Area= \frac{1}{4}\sqrt{5(5+2\sqrt{5})} *10^2=172.0477 in^2}[/tex]

Answer:

(x - 0)² + (y - 9)² = (√87.25)²

Step-by-step explanation:

equation of circle is (x - a)² + (y - b)² = r², where a and b are centre of the circle and r is the circle's radius.

(x - 0)² + (y - 9)² = r²

x² + (y² - 18y + 81) = r²

x² + y² - 18y + 81 = r²

at the point (7.5, 5):

(7.5)² + (5)² - 18(5) + 81

= 87.25

so r² = 87.25.

in standard form:

(x - 0)² + (y - 9)² = (√87.25)²

In the linear equation, the values of x and y are  10 and 5

A linear equation is an algebraic equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.  The standard form of a linear equation in one variable is of the form Ax + B = 0, where x is a variable, A is a coefficient, and B is a constant.

the given equation is 2x+4y = 20

to find the value of x, make y to be zero first

2(0) + 4y = 20

0+4y = 20

4y = 20 making y the subject of the relation to have

y = 5

Then when y = 0

2x +4(0) = 20

2x = 20 therefore making x the subject of the relation,

x = 10

Therefore the values of x and y are 10 and 5 respectively

In Mathematics and Geometry, the sum of the angles in a triangle is equal to 180. This ultimately implies that, we would sum up all of the angles as follows;

a + c + b = 180°

12° + 27° + b = 180°

39° + b = 180°

b = 180° - 39°

b = 141°
