HELP PLEASE ON 13- A, B, C<br><br>Can anyone tell me if the ones I did are right

KiRa [710]

13a.) If you're dividing and the base (in this case the base is 10) is the same, subtract the exponents.
${10}^{7} \div {10}^{5} = {10}^{7 - 5} = {10}^{2}$
13b.) If you're multiplying and the base is the same, then you add the exponents:

${s}^{2} \times {s}^{3} \times s = {s}^{2 + 3 + 1} = {s}^{6}$
13c.) This is similar to 13b:

${6}^{4} \times {6}^{3} \times 6 = {6}^{4 + 3 + 1} = {6}^{8}$

If f(x) = 25 -x^2 and g(x) = x + 5, what is (f/g)(x)? <br>Write your answer in the simplest form.

nikdorinn [45]

Answer:

Step-by-step explanation:

We are asked to divide the first equation f(x) by the second equation g(x) and then multiply the division by x

We will be using the difference of two squares to solve this question somewhere in the process

(f/g) * x

(25-x^2) / (x+5) * x

Surface area of cylinder

steposvetlana [31]

Answer:

The answer is C. $256\pi$ $in^2$ .

Step-by-step explanation:

To solve for the surface area of this cylinder, start by using the cylinder surface area formula, which is $SA=2\pi rh+2\pi r^{2}$ . Next, plug in the information given from the problem into the formula, which will look like $SA=(2)(\pi )(8in)(8in)+(2)(\pi )(8in^{2})$ . Then, simplify the equation, which will look like $SA=(128in)(\pi) +(128in)(\pi)$ . The next step is to simplify the equation further, which will look like $SA= 256\pi$ $in^{2}$ . The final answer is $256 \pi$ $in^2$ .
