Answer:
169
Step-by-step explanation:
if S(n)=n^2
so,S(13)=13^2
n=13
n^2=13^2
=169
This is C. cos Z = sin (90 - Y)
Answer:
(x+5)²
Step-by-step explanation:
To solve this we just need to shift the graph 5 spots to the left
to do this we need to add 5 to the x
(x+5)²
Answer:
13
Step-by-step explanation:
it's a 5,12,13 triangle
and we can find the sides by Pythagorean theorem:
a^2 + b^2 = root of c
25 + 144 = 169
root of 169 = 13
