First you need to find what the hourly rate is and what the flat rate is. The hourly rate is $18 and the flat rate is $40. Then you add $40+ (18x). Substitute 2 in for x for the hours and get $76.

A ball is shot from a cannon into the air. The equation that's gives the height (h) of the ball of any time (t) is: h(t)= -16t^2
Gre4nikov [31]

Answer:

26.5 units

Step-by-step explanation:

The height of the ball at any time t is given by :

h(t)= -16t^2 + 40t + 1.5 ...(1)

We need to find the maximum height of the ball.

For maximum height, put \dfrac{dh}{dt}=0

i.e.

\dfrac{d( -16t^2 + 40t + 1.5)}{dt}=0\\\\-32t+40=0\\\\t=\dfrac{40}{32}\\\\t=1.25\ s

Put t = 1.25 in equation (1) to find the maximum height.

So,

h(t)= -16(1.25)^2 + 40(1.25) + 1.5\\\\=26.5\ units

So, the maximum height reached by the ball is 26.5 units.
