Answer:
zeros: -11 , 7
Line of symmetry: x = -2
Step-by-step explanation:
y = 2x² + 8x - 154 = 2*(x² + 4x - 77) = 2*(x+11)(x-7)
y = 0
x = - 11 or x = 7
line of symmetry: x = 1/2 (-11 + 7) = -2
2x² + 8x - 154 = 2*(x² + 4x +4) - 162 = 2 * (x+2)² - 162
vertex (h , k): h = -2 , k = -162
Line of symmetry: x = -2
Answer:
9 feet
Step-by-step explanation:
2 1/4 can be written as an improper fraction 9/4
we are given:
1 inch ----> corresponds to 4 feet
hence,
2 1/4 inch ---> corresponds to 4 feet x 2 1/4 = 4 x (9/4) = 9 feet
Answer:
There is no sufficient evidence

I don't really understand it that much either but I think that the answer is A cause a rectangle has two small sides and two longer sides sooo hope this helps :D
Take log of both sides

Use log property to get "x" out of the exponent

Differentiate

Move y to Right side (Note y = original expression)

In general, whenever you have a function in the form

The derivative will be
