The inverse function r(m), to find the radius of a sphere with mass, m is:

r(m) = ∛(3m/50π)

From the question, we are to determine the inverse function r(m), to find the radius of a sphere with mass, m

From the given information, we have that

m(r) = 50/3 πr³

This can be written as

m = 50/3 πr³

To determine the inversion function r(m), we will simply make r the subject of the above equation

m = 50/3 πr³

Multiply both sides of the equation by 3/50

3/50 × m = 3/50 × 50/3 πr³

3/50 × m = πr³

Divide both sides by π

3/50 × m/π = πr³/π

3/50 × m/π = r³

This can be written as

r³ = 3/50 × m/π

Take the cube root of both sides

r = ∛(3m/50π)

Thus, the inverse function is

The remainder when  ƒ(x) = 2x³ – 3x – 2 is divided by x - 4 is 114.

To find the remainder when ƒ(x) is divided by (x - 4), we can use the remainder theorem, which states that the remainder when a polynomial ƒ(x) is divided by (x - a) is equal to ƒ(a).

So, we need to evaluate ƒ(4) to find the remainder when ƒ(x) is divided by (x - 4).

ƒ(x) = 2x³ – 3x – 2

ƒ(4) = 2(4)³ – 3(4) – 2

ƒ(4) = 2(64) – 12 – 2

ƒ(4) = 128 – 14

The value of c in increasing order which satisfy the Rolle's theorem for a given function is equal to  c = 1/4 and c = 3/4.

Function f(x) = 7sin(2πx) ,

Interval = [0, 1]

To apply Rolle's Theorem, check the following conditions,

f(x) must be continuous on the closed interval [a, b].

Here, the interval is [0,1].

f(x) must be differentiable on the open interval (a, b).

f(a) = f(b)

Function f(x) = 7sin(2πx).

f(x) is continuous on the interval [0, 1].

f(x) is differentiable on the interval (0, 1), and its derivative is,

f'(x) = 14π cos(2πx)

The derivative is continuous on the interval (0, 1).

f(0) = 7sin(0)

     = 0

f(1) = 7sin(2π)

     = 0

Since f(0) = f(1) = 0,

⇒ As per Rolle's Theorem there exists at least one number c in the interval (0, 1) .

Such that f'(c) = 0.

Values of c that satisfy this conclusion,

Solve the equation

f'(c) = 14π cos(2πc)

⇒14π cos(2πc) = 0

⇒ cos(2πc) = 0

This equation has solutions at c = 1/4 and c = 3/4,

As

cos(2π(1/4))

= cos(π/2)

= 0

and

cos(2π(3/4))

The values of "l" and "r" that maximize the area of the rectangular region are approximately 326.5 ft and 105.6 ft, respectively.

To find the values of "l" and "r" that maximize the area of the rectangular

region of the racetrack, we need to use optimization techniques.

Let's start by breaking down the rectangular region into its two

components: a rectangle and two semicircles.

Let "l" be the length of the rectangle and "r" be the radius of the

semicircles. Then we can express the area of the rectangular region as:

A = l(1056/5 - 2r)

the length of the track is 1056 ft, or 1/5 of a mile. Since there are two

semicircular ends, the length of the rectangle is equal to the length of

the track minus the combined length of the two semicircles, which is 2r.

To find the values of "l" and "r" that maximize the area of the rectangular

region, we need to find the critical points of the function A(l, r). To do this,

we can take partial derivatives of A with respect to both "l" and "r", and

set them equal to zerhttps://brainly.com/question/30883489o:

∂A/∂l = 1056/5 - 2r = 0

∂A/∂r = -2l + (2112/5 - 4πr) = 0

Solving the first equation for "r", we get:

r = 528/5

Substituting this value of "r" into the second equation and solving for "l", we get:

l = (2112/5 - 4πr)/2

l ≈ 326.5 ft (rounded to the nearest foot)

To set up a hypothesis test for this production process, we need to define the null and alternative hypotheses. The null hypothesis (H0) is that the average amount of soda in each can is equal to 6.8 ounces, while the alternative hypothesis (Ha) is that the average amount of soda in each can is not equal to 6.8 ounces.

We can then collect data by taking regular random samples from the production process and calculate the sample mean and standard deviation. We can then perform a statistical test such as a t-test or z-test to determine whether we can reject or fail to reject the null hypothesis.

If we reject the null hypothesis, we can conclude that there is evidence that the average amount of soda in each can is different from 6.8 ounces. If we fail to reject the null hypothesis, we cannot conclude that there is evidence that the average amount of soda in each can is different from 6.8 ounces.

The pair of required complementary angles are 26.2° and 63.8° respectively.

Two angles are said to be supplementary angles because they combine to generate a linear angle when their sum is 180 degrees.

When two angles add up to 90 degrees, however, they are said to be complimentary angles and together they make a right angle.

If the total of two angles is 90o (ninety degrees), then the angles are complementary.

A 30-angle and a 60-angle, for instance, are two complementary angles.

So, to find the 2 angles which are complementary:

x + x + 37.6 = 90

Now, solve it as follows:

x + x + 37.6 = 90

2x = 90 - 37.6

2x = 52.4

x = 52.4/2

x = 26.2

Now, x = 26.2 and the second angle x + 37.6 is = 26.2 + 37.6 = 63.8°.

Since each cube has an edge length of 1/5 inch, the length, width, and height of the rectangular prism must be multiples of 1/5 inch. Let's call the length of the rectangular prism "L", the width "W", and the height "H". Then we have

L = 1/5 × x

W = 1/5 × y

H = 1/5 × z

The minimum score required for an A grade is approximately 87 when the standard deviation is 7.4 and the mean is 77.1

The standard deviation is a measure of the amount of variation or dispersion in a set of data. It measures how much the individual data points deviate or differ from the mean or average of the data set.

Mathematically, the standard deviation is the square root of the variance, which is calculated by taking the average of the squared differences of each data point from the mean. The formula for the standard deviation is:

σ = sqrt(Σ(x - μ)^2 / n)

where σ is the standard deviation, x is a data point, μ is the mean, and n is the number of data points.

First, we need to find the z-score corresponding to a score that is at the 92nd percentile (the top 8%). We can use the inverse normal distribution function (also known as the probit function) to do this:

invNorm(0.92) ≈ 1.41

This means that a score at the 92nd percentile corresponds to a z-score of approximately 1.41.

Next, we need to convert this z-score to a raw score on the test. We can do this using the formula:

z = (x - μ) / σ

where z is the z-score, x is the raw score, μ is the mean, and σ is the standard deviation.

Rearranging this formula to solve for x, we get:

x = z*σ + μ

Substituting the values we have, we get:

x = 1.41*7.4 + 77.1 ≈ 87.4

Therefore, the minimum score required for an A grade is approximately 87, rounded to the nearest whole number.

Answer: Let x be the measure of the smallest angle in the triangle. Then we have:

One angle is three times as large as another, so the second angle is 3x.

The third angle is 80° more than the smallest angle, so it is x + 80.

The sum of the angles in a triangle is always 180°, so we can write an equation:

x + 3x + (x + 80) = 180

Simplifying and solving for x, we get:

5x + 80 = 180

5x = 100

x = 20

Therefore, the smallest angle in the triangle is x = 20 degrees, the second angle is 3x = 60 degrees, and the third angle is x + 80 = 100 degrees.

the mean absolute deviation for the given data set is 1.86.

Step-by-step explanation:

To find the mean absolute deviation, we first need to find the mean of the data set.

Mean = (1.25 + 3.50 + 2.55 + 8.20 + 4.80 + 0.30 + 0.75 + 2.25) / 8 = 3.07

Next, we find the absolute deviation of each data point from the mean by subtracting the mean from each data point and taking the absolute value:

|1.25 - 3.07| = 1.82

|3.50 - 3.07| = 0.43

|2.55 - 3.07| = 0.52

|8.20 - 3.07| = 5.13

|4.80 - 3.07| = 1.73

|0.30 - 3.07| = 2.77

|0.75 - 3.07| = 2.32

|2.25 - 3.07| = 0.82

Then, we find the mean of these absolute deviations:

Mean absolute deviation = (1.82 + 0.43 + 0.52 + 5.13 + 1.73 + 2.77 + 2.32 + 0.82) / 8

Mean absolute deviation = 1.86

Therefore, the mean absolute deviation for the given data set is 1.86.

Sarah then purchased 9 coach seats as by increasing the first equation by 190 and deducting it from the second equation.

An equation is a logical statement that utilises the equal sign to demonstrate the equality of two expressions. Factors, constants, and mathematical like addition, reduction, multiply, division, and exponentiation can all be found in it. Equations are utilised to find solutions for problems in both mathematics and the real world.

given

Let's use the letters "c" for the quantity of coach tickets and "f" for the quantity of first-class tickets. We are aware that there were 12 travellers in all, so

c + f + 1 = 12

We also know that the entire cost of the airfare was $4650, with coach tickets costing $190 and first-class tickets costing $980. With this knowledge, we can construct the equation shown below:

[tex]190c + 980f = 4650 - 980[/tex]

When we simplify this equation, we obtain:

[tex]190c + 980f = 3670[/tex]

Elimination can now be used to find either "c" or "f." By increasing the first equation by 190 and deducting it from the second equation, let's get rid of "c":

[tex]190c + 190f + 190 = 2280[/tex]

-190c - 980f = -3670

-790f = -1390

f = 1.76

We can round "f" up to 2 because we cannot have a fractional number of persons.

c + 2 + 1 = 12

c = 9
