Answer:
D
Step-by-step explanation:
Given
x² - 10x = - 36
Solve using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 5)x + 25 = - 36 + 25
(x - 5)² = - 11 ( take the square root of both sides )
x - 5 = ± 
( add 5 to both sides )
x = 5 ± i
Thus
x = 5 - i
or x = 5 + i
False, it's always on the vertex of the parabola.
Answer:
-3 > -8
-4 < 10
0 > -1
-5 = -5
Step-by-step explanation:
one is bigger than the other hopes this helps
Given the function s(t) = -9 -3t, differentiating the function gives the instantaneous velocity.
s’(t) = -3
This means that the velocity is not a function of time and is therefore constant. The velocity at t = 8 ( or any time for that matter) is -3 units/time.
