Essentially, we just use the pythagorean theorem to solve:
7^2 + 3^2 = c^2
49 + 9 = c^2
58 = c^2
c = sqrt 58
The answer is Option D.
Answer:
x=-5-3
It cannot be more simplified.
Answer:
B)All the real numbers
Step-by-step explanation:
the given Graph is Parabola
so the function has to be quadratic
we know that the domain of a quadratic function is always 
hence, our answer is B
Answer:
x ≈ 54.8°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan x =
=
=
, then
x =
(
) ≈ 54.8° ( to the nearest tenth )
D)42 because u first have to multipy left to right then divide left to right then do the same thing with add and subtract
