Answer:
vertex = (- 2, - 36)
Step-by-step explanation:
Given a parabola in standard form : y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= - 
f(x) = 5x² + 20x - 16 is in standard form
with a = 5, b = 20 and c = - 16
= - 
= - 2
Substitute x = - 2 into f(x) for corresponding y- coordinate
f(- 2) = 5(- 2)² +20(- 2) - 16 = 20 - 40 - 16 = - 36
vertex = (- 2, - 36)
Answer:
c
Step-by-step explanation:
If it equals the double of one angle that means it is bisected in to 2 equal parts
Answer:
9.7303888 miles
Step-by-step explanation:
Given the following :
Set target = 12 miles per week.
Miles ran on Monday = 4 3/4 miles
Miles ran on Wednesday = 3 1/3 miles
Miles ran on Friday = 1 11/17 miles
Number of miles covered for the week:
(miles covered on Monday + miles covered on Wednesday + miles covered on Friday)
= (4 3/4 + 3 1/3 + 1 11/17) miles
= (19/4 + 10/3 + 28/17) miles
= (4.75 + 3.33333 + 1.6470588) miles
= 9.7303888 miles
Slope is 12/6=2
y+6=2(x+4)
y=2x-2
