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.

What is the equation of the line that passes through (2, 7) and is perpendicular to y= -5
timofeeve [1]

Answer:

x = 2

Step-by-step explanation:

y = - 5 is a horizontal line parallel to the x- axis.

A line perpendicular to it will be a vertical line parallel to the y- axis with equation

x = c

Where c is the value of the x- coordinates the line passes through.

The line passes through (2, 7) with an x- coordinate of 2, thus

x = 2 ← is the equation of the perpendicular line

if the sum of a number and nine is doubled, the result is seven less than the number. find the number.
avanturin [10]
X=the number we have to find.
This expression "2(x+9)" is when the sum of a number and nine is doubled.
If the result is seven less than the number, we will have: x-7

We can suggest the following equation:
2(x+9)=(x-7)
2x+18=x-7
2x-x=-7-18
x=-25

answer: the number would be:  -25.

Log(1+y) - log(1-y) = log x in 2 decimal places, express y in terms of x
GaryK [48]

Answer: y = \frac{x-1}{x+1}

Step-by-step explanation:

log(1+y) - log(1-y) = log x \\log\frac{1+y}{1-y} =log x\\x = \frac{1+y}{1-y}\\x(1-y)=1+y\\x-xy=1+y\\x-1 = xy+y\\y(x+1)=x-1\\y=\frac{x-1}{x+1}
