Here, C = 2<span>πr

Divide both sides by 2</span><span>π,
so, C / 2</span>π = 2πr/2<span>π
r = C/2</span><span>π

In short, Your Answer would be: C/2</span><span>π

Hope this helps!</span>

Solving for r

divide 2 to both sides of the equation
C/2 = 2/2 pi * r
2/2=1

C/2 = pi * r

divide pi to both sides of the equation
C/(2 pi) = pi/pi *r
pi/pi=1

r= C/(2 pi)

not hard, just 2 steps or 1 if you divide by 2 pi at the same time

What is the quotient written in scientific notation? 6 x 10^24 /8 x 10^8

Artist 52 [7]

When you divide 6x10^24 by 8x10^8 you end up with $\frac{6}{8} x10^{16}$

This simplifies to $0.75x10^{16}$

Now this number is not written in scientific notation as it does not have its first digit before the decimal, so we must move the decimal of this one to the right.

To do that you must multiply the number by 10.

This means that the exponet of 10 must decrease by 1.

This makes the answer $7.5x10^{15}$

Given two points M & N on the coordinate plane, find the slope of MN , and state the slope of the line perpendicular to MN .

telo118 [61]

Answer:

Problem 1) $m = \dfrac{1}{4}$ $slope_{perpendicular} = -4$

Problem 2) $m = \dfrac{1}{3}$ $slope_{perpendicular} = -3$

Step-by-step explanation:

$slope = m = \dfrac{y_2 - y_1}{x_2 - x_1}$

$slope_{perpendicular} = \dfrac{-1}{m}$

Problem 1) M(9,6), N(1,4)

$slope = m = \dfrac{6 - 4}{9 - 1} = \dfrac{2}{8} = \dfrac{1}{4}$

$slope_{perpendicular} = \dfrac{-1}{\frac{1}{4}} = -4$

Problem 2) M(-2,2), N(4,-4)

$slope = m = \dfrac{4 - 2}{4 - (-2)} = \dfrac{2}{6} = \dfrac{1}{3}$

$slope_{perpendicular} = \dfrac{-1}{\frac{1}{3}} = -3$
