Answer:

Step-by-step explanation:

we can use the laws of exponents, which state that when multiplying terms with the same base, we add their exponents. In this case,both terms have a base of 8, so we can add their exponents of 2/7 and 1/4.

First, let's write 8 as a power of 2: 8 = 2^3. Then we can rewrite the original expression as (2^3)^(2/7) * (2^3)^(1/4). Using the power of a power rule, we can simplify this to 2^(3 * 2/7) * 2^(3 * 1/4).

Next, we can simplify the exponents by finding a common denominator. The smallest common multiple of 7 and 4 is 28, so we can rewrite the exponents as 6/28 and 21/28, respectively. Thus, we have 2^(3 * 6/28) * 2^(3 * 21/28).

Now we can simplify the exponents by multiplying the bases and exponents separately: 2^(18/28) * 2^(63/28). We can simplify the fractions by dividing both the numerator and denominator by 2, giving us 2^(9/14) * 2^(63/28).

Finally, we can add the exponents since we are multiplying terms with the same base: 2^(9/14 + 63/28). We can simplify the exponent by finding a common denominator of 28,

giving us 2^(36/28 + 63/28) = 2^(99/28). This is our final answer, which is an irrational number that is approximately equal to 69.887.

The sample space for Ella's compound event where she rolls a die and then flips a coin can be represented in the table below:

Die: 1 2 3 4 5 6
Coin: H-1 H-2 H-3 H-5 H-6 T-1 T-3 T-4 T-5

The size of the sample space is the total number of possible outcomes, which in this case is the number of rows in the table. We can see that there are 9 rows in the table, so the size of the sample space is 9.

To understand the sample space, we can imagine that each row in the table represents a possible outcome of the compound event. For example, the first row represents the outcome where Ella rolls a 1 on the die and gets heads on the coin. The second row represents the outcome where Ella rolls a 2 on the die and also gets heads on the coin, and so on.

Understanding the sample space is important in probability theory because it allows us to calculate the probability of specific events occurring. By knowing the size of the sample space and the number of favorable outcomes, we can determine the probability of an event happening.

Carl will be charged 7.84% of the initial loan amount as interest.

When taking out a loan, it's important to understand the interest rate and how it will affect the total amount you will owe. In this case, Carl's loan accrues interest at a flat rate of 1.96% per quarter. This means that every quarter, Carl will be charged 1.96% of the initial loan amount as interest.

To determine the equivalent yearly simple interest rate, we use the formula: Yearly interest rate = Quarterly interest rate x 4. This formula works because there are four quarters in a year, so we can multiply the quarterly interest rate by four to get the annual interest rate.

In this case, the quarterly interest rate is 1.96%. Multiplying this by four, we get an annual interest rate of 7.84%. This means that over the course of a year, Carl will be charged 7.84% of the initial loan amount as interest.

Understanding the interest rate is important because it can significantly impact the total amount that you will owe on a loan. A higher interest rate means that you will pay more in interest over the life of the loan, which can make the loan more expensive overall.

By calculating the equivalent yearly simple interest rate, Carl can better understand how much he will owe in interest over the course of the loan and make an informed decision about whether or not to take out the loan.

To find the radius of the cylinder, we can use the formula for the volume of a cylinder, which is pi*(r1^2)*h, where r1 is the radius and h is the height. Given that the cylinder has a height of 6 centimeters and a volume of 302 cubic centimeters, we can solve for r1 by dividing the volume by pi times the height, and then taking the square root of the result. After rounding to the nearest whole centimeter, the radius of the cylinder is approximately 5 centimeters.

MARK AS BRAINLIEST!!!

Surface area of the cylinder in terms of [tex]$\pi$[/tex] is [tex]$5904\pi m^2$[/tex].

The surface area of a cylinder can be calculated by adding the area of the two bases (which are circles) and the lateral area (which is the area of the curved surface).

The radius of the cylinder is given as 36m and the height as 46m. Therefore, the diameter of the cylinder is 72m (twice the radius). Using the formula for the area of a circle, we can calculate the area of each base:

[tex]$A_{base} = \pi r^2 = \pi (36m)^2 = 1296\pi m^2$[/tex]

The lateral area of the cylinder can be calculated using the formula:

[tex]$A_{lateral} = 2\pi r h$[/tex]

Substituting the given values, we get:

[tex]$A_{lateral} = 2\pi (36m) (46m) = 3312\pi m^2$[/tex]

Therefore, the total surface area of the cylinder is:

[tex]$A_{total} = A_{base} + A_{lateral} + A_{base} = 2A_{base} + A_{lateral}$[/tex]

Substituting the values we calculated, we get:

[tex]$A_{total} = 2(1296\pi m^2) + 3312\pi m^2 = 5904\pi m^2$[/tex]

So the surface area of the cylinder in terms of [tex]$\pi$[/tex] is [tex]$5904\pi m^2$[/tex].

A geometric sequence is a type of sequence where each term is found by multiplying the previous term by a constant factor. This means that each term is a multiple of the one before it. In contrast, an arithmetic sequence is a type of sequence where each term is found by adding a constant value to the previous term.

This means that each term is a sum of the one before it and a fixed value.

To answer your question, whether a geometric sequence will always grow faster than an arithmetic one depends on the values of the constant factor and fixed value in each sequence. In general, if the constant factor in a geometric sequence is greater than 1, the terms will grow at an increasingly faster rate than in an arithmetic sequence.

However, if the constant factor is between 0 and 1, the terms will grow at a decreasing rate, meaning that the sequence will actually grow more slowly than an arithmetic one.

It's important to note that the rate of growth is not the only factor to consider when comparing geometric and arithmetic sequences. The actual values of the terms in each sequence can also differ significantly, depending on the starting term and the values of the common ratio and common difference.

In some cases, an arithmetic sequence may actually have higher values than a geometric one, even if it grows more slowly.

In summary, whether a geometric sequence will always grow faster than an arithmetic one depends on the specific values of each sequence. However, in general, if the constant factor in a geometric sequence is greater than 1, it will grow faster than an arithmetic sequence.

The statement "Dilation 2 has a scale factor 2" (option b).

Dilation is a transformation that changes the size of an object but not its shape. It is a type of transformation that enlarges or reduces an object by a certain factor called the scale factor. The scale factor is a ratio of the size of the dilated image to the size of the original image.

Now, let's talk about the scale factor for each dilation you asked about.

For dilation 1, the scale factor is 1. This means that the size of the dilated image is the same as the size of the original image. In other words, there is no change in size. This type of dilation is often referred to as the identity transformation because it doesn't change the shape or size of the original object.

For dilation 2, the scale factor is 2. This means that the size of the dilated image is twice as large as the size of the original image. In mathematical terms, if the original object has a length of 'x', then the length of the dilated image will be '2x'. Similarly, if the original object has a width of 'y', then the width of the dilated image will be '2y'.

For dilation 3, the scale factor is 3. This means that the size of the dilated image is three times as large as the size of the original image. In mathematical terms, if the original object has a length of 'x', then the length of the dilated image will be '3x'. Similarly, if the original object has a width of 'y', then the width of the dilated image will be '3y'.

a. The two companies charge the same for 14 tons of sugar.

b. The cost when the two companies charge the same is $7953.50.

a. Let's represent the amount of sugar as x, and the total cost as C. Then we can set up the following equations for each company:

Company 1: C = 5143 + 200.75x

Company 2: C = 5500 + 175.25x

To find the amount of sugar for which the two companies charge the same, we can set the two equations equal to each other and solve for x:

5143 + 200.75x = 5500 + 175.25x

25.5x = 357

x = 14

So the two companies charge the same for 14 tons of sugar.

b. To find the cost when the two companies charge the same, we can plug in x = 14 into either equation. Let's use Company 1's equation:

C = 5143 + 200.75x
