Answer:

r≈5.73in

Step-by-step explanation:

Using the formula

C=2πr

Solving for r

$C=\frac{C}{2\pi } =\frac{36}{2}$ · $\pi$ ≈5.72958in

Answer:

r = 18/pi

or approximately 5.7325 inches

Step-by-step explanation:

The circumference is given by

C = 2*pi*r

36 = 2*pi*r

Divide each side by 2 pi

36/(2pi) = r

18/pi = r

Letting pi = 3.14

18/3.14

5.732484076 = r

What's the domain and range for (×+4)-1

Sonja [21]

$\bf a^{-{ n}} \implies \cfrac{1}{a^{ n}}\qquad \qquad

\cfrac{1}{a^{ n}}\implies a^{-{ n}}\\
---------------\\
thus\\
(x+4)^{-1}\implies \cfrac{1}{x+4}
\\\\
$
$\bf if\qquad \cfrac{1}{0} \implies$ undefined

so.. what value of "x" makes x+4 to 0?

the domain will be, all real numbers, except that value

about the range, "y" will take, whateve "x" can provide.. in this case... I think is all real numbers, except 0, because, if you give a few big values to "x", the fraction will simply have a bigger and bigger denominator, making the fraction smaller and smaller, ever approaching 0, but never getting there

seraphim [82]

P = 2L + 2W ok

2L = P - 2W

L = (P - 2W)/2 This is the correct answer

I think it's letter C

Problem 2.

4x - 4 > 12

4x > 12 + 4

4x > 16

x > 16/4

x > 4 This is the correct choice
