= -78+29
= -49
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.
The answer is b good luck!!!
Answer:
C 24 ft wide, 18 ft deep
Step-by-step explanation:
there are 4 (2) in 8, so 4 x 6 = 24
there are 3(2) in 6, so 3 x 6 = 18
The larger scale drawing will be 24ft x 18 ft
