Find the third side in simplest radical form:

\sqrt(53)

Step-by-step explanation:

Pythagorean theorem: a^2+b^2=c^2

36+b^2 = 89

b^2 = 53.

b = \sqrt(53)

(because a side length cannot be negative.)

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
