Question 7 of 10 The domain (input values) of the cosine function is:
A. angle measures less than 2(pie) radians.
B. angle measures between 0 and (pie) radians.
C. angle measures less than 90°.
O D. all negative and positive angle measures.

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

a is the correct

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
