Which equation using x to represent time best represents the floor number of an elevator descending at a steady rate?

zepelin [54]

C. You'd be starting at a higher floor (positive number) and descending floors (negative number per x). If you assume x is time it's a little more logical and visual.

Answer:

$\Huge\boxed{131.88}$

Step-by-step explanation:

Hello There!

First thing we want to do is find the formula for circumference of a circle

C = 2(3.14)r

where r = radius

we are given the diameter so we have to convert that into radius to do so we just divide by 2

42/2=21 so the radius equals 21 inches

now we just plug in 21 for r in the formula

$C = 2(3.14)21\\2*3.14=6.28\\6.28*21=131.88\\C=131.88$

So we can conclude that the circumference of the circle is 131.88 inches

Answer:

$16\sqrt{17}$

Step-by-step explanation:

The perimeter is two times width plus two times length:

$2\sqrt{17} + 2\cdot 7\sqrt{17} = 2\sqrt{17} + 14\sqrt{17} = 16\sqrt{17}$

There is no way to simplify further.
