The inverse function should be 1/2x - 2
Explanation:
The inverse of something is just it's opposite. The opposite of squaring is dividing in half, so we get 1/2x. Obviously the opposite of addition is subtraction so our answer is 1/2x - 2
I hope this helps!
Answer:
C.
Step-by-step explanation:
The inverse of tangent would be opposite/adjacent.
Answer:
a = 1/25
Step-by-step explanation:
The vertex form of the parabola is
y = a(x-h)^2 +k
where (h,k) is the vertex
y = a(x-2)^2 -4
We have a point on the parabola (-3,-3) so substitute this into the equation
-3 = a(-3-2)^2 -4
-3 = a(-5)^2 -4
Add 4 to each side
-3+4 = a(25) +4-4
1 = 25a
Divide each side by 25
1/25 = a
y = 1/25(x-2)^2 -4
The equation to solve for the rectangle’s length would be P=2(length) + 2(width). The rectangle’s length is 10.5 units.
