Please help Lazlo throws a ball that moves according to the function:
h(t) = -4.9+2 + 40t + 1.5, where h(t) is the height in metres and t is the time in seconds.
a) For how long is the ball in the air?
b) How high does the ball go?
c) How long does it take for the ball to reach its maximum height?
d) At what time(s) does the ball reach a height of 10 m?
e) At what time does the ball reach a height of 90 m?
[Application = 3+3 + 2 + 3 + 2 = 13]

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

ωєℓℓ ωιтн тнαт ιиfσ

тнє вαѕє ιѕ 30

αи∂ тнє нєιgнтн ιѕ 30

нσρє ι ¢συℓ∂ нєℓρ

the answer is 3.54 g/cm^3

step-by-step explanation:

d=mass/volume therefore d= 46/13 which is a simple division equation.

if your equation is in the form ax2 + bx + c, you can find the maximum by using the equation:

max = c - (b2 / 4a).

the first step is to determine whether your equation gives a maximum or minimum.

-x2 + 4x - 2.     thats an example hope it
