f(6) = 109
Step-by-step explanation:
If f(x) = 3x 2 + 1 we replace x with 6 in the given function
f(6) = 3×6^2 + 1 first find the second power of 6
6^2 = 36 then multiply it by 3
36 × 3 = 108 and then add 1
108 + 1 = 109
b. 24 mm
step-by-step explanation:
use the pythagorean theorem.
a^2 + b^2 = c^2
a^2 + 7^2 = 25^2
a^2 + 49 = 625
a^2 = 576
a = 24
answer: b. 24 mm
answer is c
