Answer:
A
Step-by-step explanation:
Plug in 6 for x and get
21600
To find the profit subtract the starting amount (15,000)
21600-15000=6600
Answer:
x = -
Step-by-step explanation:
Given a quadratic equation in standard form , that is
y = ax² + bx + c = 0 ; a ≠ 0
Then the x- coordinate of the vertex is
= -
x² + bx + c = 0 ← is in standard form
with a = 1, b = b, thus
= -
Answer:
a) V' = 81(1)^2 = 81 cm^3/s
b) V' = 81(10)^2 = 8,100 cm^3/s
Step-by-step explanation:
Recall that the volume of a cube is:
V = s^3
If you let t be the time in a seconds, then s = 3t at time t. So we have that the volume of the cube at time t is:
V = (3t)^3 = 27t^3
Taking derivatives:
V' = 81t^2
Then, the speed of which the volume changes is:
a) V' = 81(1)^2 = 81 cm^3/s
b) V' = 81(10)^2 = 8,100 cm^3/s
