Answer: The first box
Step-by-step explanation:
V represents volume and r represents radius
So V(r) represents the volume of the basketball with respect to radius
Step-by-step explanation:
the question is z²=1
taking square root on both sides
√z² = √1
the square root and the square cancel out each other
it gives
z=±1
that means either z=+1 or z=-1
so the solutions are 1 and -1
Answer:
-cos(2A)
Step-by-step explanation:
We know that (a+b) (a-b) = a^2-b^2
So it means we can simplify to sin^2(A)-cos^2(A) and we know cos^2(A) - sin^2(A) = cos(2A) but we will just multiply by -1 and we get - cos(2A)
Answer:
Divide the perimeter by four.
Step-by-step explanation:
Because it is a square, all four sides should be the same length. If all sides have to be equal, you divide your perimeter by the amount of sides the shape has.
