Answer: Second Option

C = 16\pi

Step-by-step explanation:

We are evaluating aarco lengths

The formula for the arc length is:

C = 2\pi r

We want to know what is the arc length for a radius of r = 8

Then we substitute r = 8 in the equation and solve

C = 2 \pi * 8

C = 16\pi

The correct answer is the second option

Answer:

Correct choice is C=16 \pi.

Step-by-step explanation:

Given equation is C=2 \pi r.

Now we need to find the value of C using given equation C=2 \pi r and r=8.

To find that, we just need to plug r=8 into C=2 \pi r and simplify.

C=2 \pi r

C=2 \pi \times 8

C=16 \pi

Hence correct choice is C=16 \pi.

If f(x)=8x and g(x)=2x+1, what is (f×g)(x)
Sav [38]

Answer:

(f * g)(x) has a final product of 16x² + 8x.

Step-by-step explanation:

When you see (f * g)(x), this means that we are going to be multiply f(x) and g(x) together.

<em>f(x)=8x</em>

<em>g(x)=2x+1</em>

Now, we multiply these terms together.

(8x)(2x + 1)

Use the foil method to multiply.

16x² + 8x

So, the product of these terms is 16x² + 8x.
