The diameter of the hemisphere with a volume of 557 m³ is approximately 12.8 m, to the nearest tenth of a meter.

The volume of a hemisphere can be calculated using the formula V = (2/3)πr³, where V is the volume and r is the radius. Given that the volume of the hemisphere is 557 m³, we can find the radius by solving for r:

557 = (2/3)πr³

To find the radius, first, we need to isolate r³ by multiplying both sides by 3/(2π):

r³ = (3 * 557) / (2 * π)

r³ ≈ 265.18

Now, take the cube root of both sides to find the radius:

r ≈ 6.4 m

To find the diameter, simply multiply the radius by 2:

d ≈ 2 * 6.4
d ≈ 12.8 m

Answer:

(-y,x) The coordinates are switched and the y becomes a negative.

The obtained answers for the given piecewise function are:

(a) The cost of a call that is under six minutes is 0.70 (m < 6)

(b) The cost of a 14-minute call is 2.62 (m > 6; m is an integer)

(c) The cost of a 9 1/2 minute call is 1.66 (m > 6; m is not an integer)

A piecewise function is given by different functions at different intervals.

It is given that,

phone company set the following rate schedule for an m-minute call from any of its pay phones.

C(m) = 0. 70 when m ≤ 6

        = 0.70 + 0.24(m - 6) when m > 6 and m is an integer

        = 0.70 + 0.24([m - 6] + 1) when m > 6 and m is not an integer

(a) The cost of a call that is under six minutes:

Since m < 6, the cost is C(m) = 0.76

Thus, the cost of a call that is under six minutes is 0.76

(b) The cost of a 14-minute call:

Since 14 > 6, the cost is C(m) = 0.70 + 0.24(m - 6) when m > 6 and m is an integer.

C(14) = 0.70 + 0.24(14 - 6)

        = 0.70 + 0.24(8)

        = 0.70 + 1.92

        = 2.62

Thus, the cost of a 14-minute call is 2.62.

(c) The cost of a 9 1/2 minute call:

9 1/2 = 19/2 = 9.5

Since 9.5 > 6, the cost is C(m) = 0.70 + 0.24([m - 6] + 1) when m > 6 and m is not an integer.

C(9.5) = 0.70 + 0.24([9.5 - 6] + 1)

          = 0.70 + 0.24([3.5] + 1)

Since we know that if [x] is a function then its domain is R and the range is Z(integer)

So, [3.5] = 3(is an integer)

Then,

C(9.5) = 0.70 + 0.24(3 + 1)

          = 0.70 + 0.96

          = 1.66

Therefore, the cost of a 9 1/2 minute call is 1.66.

Option A is the correct answer as it correctly identifies the roles of the two boldface portions.

The two boldface portions in the argument play different roles. The first boldface portion identifies the conclusion of the argument, while the second boldface portion provides support for that conclusion.

The argument aims to prove that for a given level of output, Delta's operation now causes less fossil fuel to be consumed than it did formerly.

The first boldface portion clearly states the conclusion of the argument, while the second boldface portion provides support for this conclusion by explaining that the new technologies powered by electricity consume less fossil fuel than the older technologies.

Therefore, option A is the correct answer as it correctly identifies the roles of the two boldface portions.

The effective annual interest rate for the annuity is approximately 5%.

To calculate the effective annual interest rate for the annuity, we can use the formula:

Effective Annual Interest Rate = ((Total Payment / Principal Amount)^(1/Number of Years)) - 1

Principal Amount = $10,000

Total Payment = $2,504.57 per year for five years

Number of Years = 5 years

Let's substitute these values into the formula to calculate the effective annual interest rate:

Effective Annual Interest Rate = (($2,504.57 * 5) / $10,000)^(1/5) - 1

Calculating this expression will give us the effective annual interest rate of the annuity.

To calculate the effective annual interest rate, we use the formula:

Effective Annual Interest Rate = ((Total Payment / Principal Amount)^(1/Number of Years)) - 1

In this case, the principal amount is $10,000, the total payment is $2,504.57 per year for five years, and the number of years is 5.

Substituting the values into the formula, we have:

Effective Annual Interest Rate = (($2,504.57 * 5) / $10,000)^(1/5) - 1

Simplifying the expression, we get:

Effective Annual Interest Rate = (12522.85 / $10,000)^(1/5) - 1

Calculating this expression gives us the effective annual interest rate of the annuity.

Please note that the effective annual interest rate is expressed as a decimal, not a percentage. To convert it to a percentage, multiply by 100.

Step-by-step explanation:

Pick 2 points on the line to calculate the slope, m:  (3, 10) and (5, 12)

m = Δy/Δx = (12 - 10) / (5 - 3) = 2/2 = 1

Use the point-slope equation and the point (3, 10):   (y - y1) = m(x - x1)

(y - 10) = 1(x - 3)

y - 10 = x - 3

y = x - 3 + 10

y = x + 7

The probability that the landing uppermost of the first die is 6 given the conditions as required is; 1/36.

It follows from the task content that; the probability that the number landing uppermost on the first die is a 6 if it is known that the sum of the numbers landing uppermost is 7 is to be determined.

This implies that the first die gives 6 and the second die gives 1 so that the required probability is;

P = (1/6) × (1/6)

P = 1 / 36.

The average rate of change between hour 4 and hour 8 is equal to the  average rate of change between hour 0 and hour 4.

Function is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given,

The function f(x)=80(1.5)x

where x is the time in hours

Then,

f(4)=80(1.5)4=480

f(8)=80(1.5)8=960

f(0)=80(1.5)0=0

Then the average rate of change between 4 and 8 hours =\(\frac{960-480}{4}\)

=120 units per hour

The average rate of change between 0 and 4 hours=\(\frac{480-0}{4}\)

=120 units per hour

Hence, the average rate of change between hour 4 and hour 8 is equal to the  average rate of change between hour 0 and hour 4.

We can write the integral of f(x) as the sum of the integral of the even component, e(x), and the integral of the odd component, o(x). This gives us the following equation:  ∫f(x)dx = ∫e(x)dx + ∫o(x)dx

Integrals can be written as the sum of the integral of an odd function and the integral of an even function. This is because any function can be broken down into its even and odd components. Even functions are those that remain unchanged when reflected over the x-axis. This means that the result of evaluating the function for any x-value is the same as the result for its negative. Odd functions are those that change sign when reflected over the x-axis. This means that the result of evaluating the function for any x-value is the negative of the result for its negative.

The integral of an even function is the same regardless of whether it is written as the sum of the integral of an odd function and the integral of an even function, or if it is written just as an integral of the even function. The integral of an odd function is the negative of the integral of the even function when written as the sum of the two integrals.

The bonus question asks for the application of the integral test to determine the convergence of the series given by 2n*e^(-a).

The integral test is a method used to determine the convergence or divergence of a series by comparing it to the integral of a related function. In this case, we are given the series 2n*e^(-a), and we can use the integral test because the terms of the series involve the variable 'n', and the function e^(-a) can be integrated.

To apply the integral test, we consider the integral of the function corresponding to the series. In this case, we integrate the function f(x) = 2x*e^(-a) from 1 to infinity. If this integral converges, then the series is also convergent. Conversely, if the integral diverges, then the series is divergent.

By evaluating the integral of f(x) and analyzing its convergence or divergence, we can determine whether the given series 2n*e^(-a) converges or diverges. Showing all the steps in evaluating the integral and discussing the convergence properties of the resulting integral will be necessary to receive full credit for this question.

What is Circle ?

In geometry, a circle is a two-dimensional shape consisting of all the points that are equidistant from a given point, called the center. The distance from the center to any point on the circle is called the radius of the circle.

From the given information, we know that V, W, and X are points on a circle with center V, and that VW = WX = 3. We also know that ∠WVX = 90°.

Since WX is a diameter of the circle, it has length equal to twice the radius of the circle. Let r be the radius of the circle, then we have:

VW + WX = 2r

3 + 3 = 2r

r = 3

So the radius of the circle is 3. Since WX is a diameter, its length is 2r = 6. Therefore, the length of ⌢ WX ⌢ expressed as a fraction times π is:6÷π
