tangare [24]

Answer:

30 s

Step-by-step explanation:

When the ball hits the ground h=0. To find the time t when this happens we must solve the equation h=0.

●h= 0

● -12t^2+360t =0

● t(-12t +360) = 0

● t = 0 or -12t +360 =0

● t=0 or -12t = -360

● t=0 or 12t =360

● t=0 or t=360/12

● t=0 or t= 30

The equation has two solutions.

The ball was fired with an initial speed of 800 feet per second so it cannot hit the ground at t=0.

So the ball hits the ground after 30 s.

Answer:

A h+p ≤15

h = headphone and

p = pianos

We can only ship a maximum of 15 total

h+p ≤15

We must sell  at least 2500 dollars of product.  Headphones are 50 and pianos are 500

50h+500p ≥ 2500
