Let  u = t-300

du = dt

∫ u⁷ * (u + 300)³ * du

∫ (u¹⁰ + 900 u⁹ +270000 u⁸ + 27000000 u⁷) * du

b) Constant rate of 0.7 people per second

This is the rate of exit

at t = 0.20 people in line

People in a line at t = 300 is = 20+ ∫³⁰⁰₀ ((r(t) - 0.7 ) * dt

= 20 + ∫³⁰⁰₀ 44(t/100)³ * (1-t/300)⁷- 0.7 dt

= 20 + 270 - 0.7 * 300

= 80 people

c) t = 300 sec

people = 80

when t>300 , r(t) = 0

rate of exit remains the same

= 80 + ∫ ( 0-0.7) * dx

= 80 + [-0.7x] = 0

= 80 - [0.7x] = 0

= 80 - 0.7 t + 0.7 * 300 = 0

= 80 - 0.7t + 210 = 0

= - 0.7 t = -290

t = 414.285714 sec.

d) f(t) = 20 + ∫⁶₀ (r(x) - 0.7) * dx

f(t) = r(t) - 0.7

f(t) = 0       (for critical point)

r(x) = 44 (t/100)³ * (1-t/300)⁷

r(t) = 0

we get t= 33.0133 sec.

t = 166.575 sec.

Now check for the value

when t=0

f(t) 20

when t= 33.0133

f(t) = 3.803 ≈ 4

when t = 166.575

f(t) = 158.07 ≈ 158

when t= 300

f(t) = 80

so the minimum number of people is 4 at the time t= 33. 0133

The conversion of 70°F is equal to 21.1°C.

A temperature unit developed from the SI (International System of Units) is Celsius (symbol: °C).

Prior to the adoption of the metric system, Fahrenheit (symbol: °F) was a commonly used measurement of temperature.

To convert 70°F (degrees Fahrenheit) to Celsius (°C), you can use the following formula:

°C = (°F - 32) / 1.8

Substituting 70°F for °F in the formula, we get:

°C = (70 - 32) / 1.8

Simplifying the calculation, we get:

°C = 38 / 1.8

°C ≈ 21.1

The volume of each soup can is approximately 785.4 cubic centimeters.

The volume of a cylinder can be calculated using the formula:

Volume =[tex]\pi[/tex] ×[tex]radius^2[/tex]× height

where π (pi) is a mathematical constant approximately equal to 3.14159, the radius is the distance from the center of the circular base of the cylinder to its edge, and height is the vertical distance between the circular bases.

In other words, the volume of a cylinder is the amount of space occupied by the cylinder, and it depends on the size of the circular base and the height of the cylinder.

In this case, the radius of the can is given as centimeters and the height is also given as centimeters. So, we can substitute these values in the formula and calculate the volume:

Volume = π × [tex]radius^2[/tex] × height

Volume = π ×[tex]5^2[/tex] × 10

Substituting radius = 5 cm and height = 10 cm

Volume = 250π cubic centimeters

Using the concept of proportions, the time it takes to type 100 words is approximately 33 minutes

Let's first break down the problem and identify the given information:

The time it takes to type on a page of paper is partly constant and partly inversely proportional to the number of words.

It takes 1 hour to type 180 words.

It takes 45 minutes to type 120 words.

To solve for the time it takes to type 100 words, we can use the concept of inverse proportionality:

Let x be the time it takes to type 100 words.

We know that the time it takes to type is inversely proportional to the number of words, so we can set up the proportion:

time / number of words = constant

Using the given information, we can write two equations for the constant:

1 hour = k * 180 words

45 minutes = k * 120 words

where k is the constant of proportionality.

Solving for k in each equation:

k = 1 hour / 180 words = 1/180 hour/word

k = 45 minutes / 120 words = 3/8 minutes/word

Since we want to express the time it takes to type 100 words in minutes, we need to convert the constant to minutes/word:

1 hour = 60 minutes, so k = 1/180 * 60 = 1/3 minutes/word

45 minutes = 0.75 hours, so k = 3/8 * 60 = 22.5 minutes/word

Now we can use the constant to find the time it takes to type 100 words:

time / 100 words = constant

Plugging in the values we found for the constant:

x / 100 = 1/3 or x / 100 = 22.5

Solving for x:

x = (1/3) * 100 = 33.33 minutes (or approximately 33 minutes)

x = 22.5 * 100 = 2250 minutes (or approximately 37.5 hours)

We can discard the second solution (37.5 hours) since it doesn't make sense in the context of the problem.

Therefore, it will take approximately 33 minutes to type 100 words.

Therefore, the vertices of ∆A'B'C' are located at (-18, -18), (-6, 12), and (0, -24), and the answer is not listed among the given options.

A triangle is a geometric shape that consists of three line segments or sides that intersect at three points called vertices. The interior angles of a triangle always add up to 180 degrees, and the side opposite to the largest angle is the longest side, which is called the hypotenuse. Triangles are commonly used in geometry and in many branches of mathematics, as well as in real-world applications such as engineering, architecture, and physics.

Here,

To reflect ∆ABC over the x-axis, we need to negate the y-coordinates of each vertex. Then, to dilate the reflected triangle by a scale factor of 3 about the origin, we need to multiply each coordinate by 3.

The coordinates of the reflected triangle will be (-6, -6), (-2, 4), and (0, -8). Multiplying each coordinate by 3, we get (-18, -18), (-6, 12), and (0, -24).

Answer:

Therefore, the product of (5v + 2)(2v - 4) is 10v^2 - 16v - 8.

Step-by-step explanation:

To find the product of (5v + 2)(2v - 4), we can use the FOIL method, which stands for First, Outer, Inner, Last. This method involves multiplying the first terms, then the outer terms, then the inner terms, and finally the last terms, and then adding the resulting terms.

Using the FOIL method, we get:

(5v + 2)(2v - 4) = (5v)(2v) + (5v)(-4) + (2)(2v) + (2)(-4)

Simplifying, we get:

10v^2 - 20v + 4v - 8

Combining like terms, we get:

10v^2 - 16v - 8

Therefore, the product of (5v + 2)(2v - 4) is 10v^2 - 16v - 8.

A graph of the relationship modeled by the equation is shown in the image attached below.

If the graph continues, the point (28, 24) will not be on the graph.

The height of a picture when the total height of the picture with the frame is 38.5 cm would be 34.5 cm.

In this scenario, the total height of a picture in its frame (in centimeters) would be plotted on the y-axis of the graph while the height of the picture (in centimeters) would be plotted on the x-axis of the graph.

Based on the ordered pair (28, 24), we would determine if it lies on the graph of the equation:

y = x + 4

24 = 28 + 4

24 = 32 (False).

When the total height of the picture with the frame is 38.5 cm, the height of a picture can be calculated as follows;

y = x + 4

38.5 = x + 4

x = 38.5 - 4

the ball will be traveling downward at a velocity of 24 feet per second after approximately 2.75 seconds.

What is velocity ?

Velocity can be defined as ratio of displacement and time taken.

To find the time when the ball will be traveling downward at a velocity of feet per second, we need to find the time when the velocity is equal to that value, which means the velocity is negative.

The velocity of the ball at any time t can be found by taking the derivative of the height function with respect to time:

v(t) = -32t + 64

We need to find the time t when v(t) = -24 feet per second. So we can set up the equation:

-32t + 64 = -24

Solving for t:

-32t = -88

t = 2.75 seconds (rounded to three decimal places)

The hire purchase plan, regular price $4 049, Warranty $599, interest rate 54% with36 monthly instalments​ is $216.45.

Suppose we're given that:

P_v = Present value of the loan amount

r = rate of interest (compound interest) per period of time

n = number of period of time in which loan is to be paid off

P = A fixed period payment needed to be done for paying off the loan in n number of periods.

Then, we get:

[tex]P = \dfrac{r\times P_v}{1 - (1 + r)^{-n}}[/tex]

We are given that;

Price = $4049

Warranty= $599

Interest rate=54%

Number of installments= 36

Now,

Assuming no down payment, the total cost of the purchase with the warranty is $4,049 + $599 = $4,648.

The interest rate is 54% per annum, which translates to a monthly interest rate of 54%/12 = 4.5%.

Using the formula for the monthly payment in a hire purchase plan:

Monthly payment = Total cost / Number of months / (1 - 1 / (1 + monthly interest rate)^number of months)

Plugging in the values, we get:

Monthly payment = $4,648 / 36 / (1 - 1 / (1 + 4.5%)^36)

= $4,648 / 36 / (1 - 1 / 2.7223)

Option A. If the alternative hypothesis of the test had been lower-tailed instead of two-tailed, the conclusion of the test would be different.

Recall that a two-tailed test is used when the alternative hypothesis is that the population parameter is different from the null hypothesis value in any direction, while a lower-tailed test is used when the alternative hypothesis is that the population parameter is less than the null hypothesis value.

In the given scenario, if the alternative hypothesis of the test had been lower-tailed instead of two-tailed, we would have tested the following null and alternative hypotheses:

H0: Pharaoh's translation is not worse than the other software's translation.

Ha: Pharaoh's translation is better than the other software's translation.

In this case, we would have calculated the p-value for the lower tail of the sampling distribution, and compared it to the significance level alpha. If the p-value is less than alpha, we would reject the null hypothesis and conclude that Pharaoh's translation is better than the other software's translation. If the p-value is greater than alpha, we would fail to reject the null hypothesis and conclude that there is not enough evidence to suggest that Pharaoh's translation is better than the other software's translation.

The lithosphere's reservoir of carbon is approximately 10^5.25 or about 177,828 times greater than the biosphere's reservoir of carbon. Rounding this to the nearest order of magnitude gives an answer of (b) 10⁶.

Carbon is one of the most important elements on Earth as it forms the building blocks for life and plays a crucial role in regulating the planet's climate. The carbon cycle is a complex process that involves the exchange of carbon between different reservoirs such as the atmosphere, oceans, biosphere, and lithosphere.

To compare the size of the carbon reservoirs in the biosphere and lithosphere, we can take the ratio of the two reservoirs:

Lithosphere/Biosphere = 100,005,500/560

Simplifying the expression on the right-hand side gives:

Lithosphere/Biosphere = 178,933.93

To convert this ratio to orders of magnitude, we can take the logarithm base 10 of the ratio:

log10(Lithosphere/Biosphere) = log10(178,933.93)

log10(Lithosphere/Biosphere) ≈ 5.25

Therefore, the lithosphere's reservoir of carbon is approximately 10^5.25 or about 177,828 times greater than the biosphere's reservoir of carbon.

The sum of fractions [tex]\frac{1}{4}[/tex] and [tex]\frac{6}{8}[/tex] is equal to one.

Fraction addition teaches us how to combine two or more fractions with the same or different denominators. The addition of fractions is determined by two major factors:
1.Identical denominators
2.Various denominators
If the denominators of two fractions are the same (such fractions are said to be like fractions), they can be added directly. If the denominators are different (such fractions are known as unlike fractions), we must change the denominators and then add the fractions.

If the denominators of two or more fractions are the same, we can simply add the numerators while keeping the denominator constant.
To add fractions with the same denominators, follow the steps below:
1. Add the numerators while keeping the denominator constant.
2.Summarize the fraction.

When two or more fractions with different denominators are added together, we cannot directly calculate the numerators.
To add fractions with different denominators, follow the steps below:
1. Examine the fractions' denominators.
2.Make the fraction denominators the same by finding the LCM of the denominators and rationalising them.
3. Add the fraction numerators while keeping the denominator constant.
4.Simplify the fraction to obtain the final total.

As we have fractions with different denominator first of all we take LCM which is equal to 8.

x= 32

2. If one of the angles has a measure of 39° then other angle is

= 90 - 39

= 51 degree.

3. The angles are complementary.

2x + 3 + 2x = 90

4. Two complementary angles are expressed as 2x and 3x.

2x + 3x= 90

5x = 90

x = 18

So, 2x = 36 and 3x = 54 degree.

5. Angles j and k are supplementary angles.

<j + <k = 180

<j + 117 = 180

<j = 63

6. Two supplementary angles are ∠ABC=105° and ∠CBD=(3x−24)°.

105 + 3x -24 = 180

3x + 81 = 180

7. Two angles are supplementary. ∠ACB=4x° and ∠BCD=6x+50°.

<ACB + <BCD = 180

4x + 6x + 50 = 180

10x = 130

x= 13

So, <ACB = 4x = 4(13)= 52.

8. For two vertical angles where ∠1=2x+26° and ∠3=3x−32°

<1 = < 3

2x + 26 = 3x -32

2x - 3x = -32 - 26

-x =-58

x= 58

The surface area of the NBA basketball in terms of π is 87.96π square inches.

What is surface area ?

Surface area is the measure of the total area that the surface of an object occupies. It is a two-dimensional measure of the exposed area of an object, and is typically expressed in square units, such as square inches, square feet, or square meters.

The surface area of an object can be calculated by adding up the areas of all of its individual faces and sides. The exact method for calculating surface area depends on the shape and dimensions of the object in question. For example, the surface area of a cube can be found by multiplying the area of one face of the cube by six, while the surface area of a sphere can be calculated using the formula 4πr².

Surface area is an important concept in mathematics, and has many practical applications in fields such as architecture, engineering, and physics. For example, in architecture, surface area is used to calculate the amount of materials needed to construct a building, while in physics, surface area plays a role in determining heat transfer and other physical properties of objects.

The surface area of a sphere can be calculated using the formula:

Surface Area = 4πr²

where r is the radius of the sphere.

In this case, the radius of the NBA basketball is 4.7 inches. So, we can substitute r = 4.7 into the formula to get:

Surface Area = 4π(4.7)²

Surface Area = 4π(22.09)

Surface Area = 87.96π

Therefore, the surface area of the NBA basketball in terms of π is 87.96π square inches.

You can estimate the value of a dependent variable (Y) from a given independent variable (X) using this straightforward linear regression calculator, which uses the least squares method to find the line of best fit for a set of paired data.

You must enter paired data in the two text boxes below, with your independent variable going in the X Values box and your dependent variable going in the Y Values box (either one value per line or as a comma-delimited list).

As an illustration, if you wanted to determine the line of best fit for the relationship between height and shoe size so that you could predict shoe size based on a person's height, height would be your independent variable and shoe size your dependent variable.

This calculator is capable of estimating the value of a dependent variable (Y) given any given independent variable (X) value. Simply enter the X values for which you want to generate an estimate into the Estimate box below (either as one value per line or as a comma-delimited list).

Let a and b be two independent events, if p (a) = 0. 4 and p (a ∪ b) = 0. 64 then the value of the p(b) = 0.4

In this question, we will utilise the notion of independent events and the probability addition rule to determine the probability of event B. The product of the individual probabilities will represent the intersection of independent events.

p(a) = 0.4

p(a∪b) = 0.64

p (a ∩ b) = p(a) x p(b)

p (a ∪ b) = p(a) + p(b) - p(a) x p(b)

0.64 = 0.4 + p(b) - 0.4 x p(b)

p(b) = 0.4

Therefore, the value of the p(b) = 0.4

Independent occurrences are ones whose occurrence is unrelated to any other event. For example, suppose we flip a coin in the air and receive the result Head, then we flip the coin again and obtain the result Tail. The occurrences occur independently of one another in both circumstances. It is one of the several kinds of occurrences in probability.

Let us now look at the whole description of independent events, including a Venn diagram, examples, and how they vary from mutually exclusive events.
