He should use the Pythagorean Theorem to find the missing length.
Since KT is tangent to the circle and TL reaches the center of circle L, the measure of angle LTK is 90 degrees. This means that triangle LTK is a right triangle which means the Pythagorean Theorem can be used.
So,
TL²+(12)²=(13)²
=> TL²+144=169
=> TL²=25
=> TL = 5
Therefore, the radius of circle L is 5 feet.
Answer:
A. 81
Step-by-step explanation:
F(x)=
if x=4, then F(4) = 
= 3×3×3×3=81
Domain: (-infinity,infinity)
Range: (0, infinity)
The asymptote is at 0
The answer is C 2/5 = 0.4
Okay. So this is already set up as a proportion. Cross multiply the values in order to get 224 = 32x. Now, divide each side by 32 to isolate the variable. 224/32 is 7. x = 7. There. The unknown value is 7.
