Answer:
Step-by-step explanation:Since we want to know how much time elapsed since the object was launched until it ht the ground. At the ground, the height is 0.
Therefore the equation h(t) = 80t – 16t2 becomes 0= 80t – 16t2
Solving the equation for t gives 80t =16t2 or 16t=80 or t=5sec
The object hits the ground 5 seconds after it is launched.
Answer:
8
Step-by-step explanation:
Answer:
We are given that the two triangles are approximately equal or similar thus
angle M=angle Z = 124
angle L = angle X = 33
angle N= angle Y = ?
The total angles is 180, thus angle N or Y is 180- (124+33) = 23
Answer:
36/43 I think.
