Look at the picture.
Use Pythagorean theorem:
r^2=6^2+20^2\\\\r^2=36+400\\\\r^2=436\to r=\sqrt{4\cdot109}\to r=2\sqrt{109}ft.\\\\r\approx20.88\approx20.9ft.

Answer: <span>D) 20.9 ft </span>

Using the Pythagorean Theorem we can solve this:

20^2 + 6^2 = X^2

400 + 36 = x^2

436 = x^2

x = SQRT(436)

x = 20.9 feet long

What percent of 150 is 9?
irga5000 [103]
One of the ways to find the answer is to find how much 1 percent of 150 is. To do that we just have to divide 150 by 100:

150 / 100 = 1.5

Now we can divide 9 by 1.5 to know how much percent of 150 it is:

9 / 1.5 = 6

Let's check it:

150 * 6% = 150 * 6/100 = 15 * 6/10 = 3 * 6/2 = 18/2 = 9

It's correct then :)

Which tables represent constant functions?
Alona [7]

A function is a law that tells you how to associate inputs (x values) and outputs (y values).

In the case of constant functions, it doesn't matter which input you choose, the ouput must always be the same.

So, a constant function has always the same output (y values) for every input (x values) you feed.
