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:
303.95 m^3
Step-by-step explanation:
Volume = πr2h
r= 4.4
h = 5
= 3.14 × 4.4^2 × 5
= 3.14 × 19.36 × 5
= 303.95
Hence the volume is 303.95 m^3
Answer:
52
this is most likely the correct answer
Given the geometric progression below
The nth term of a geometric progression is given below
From the geometric progression, we can deduce the following
To find the value of r, we will take ratios of two consecutive terms
To find the 9th term of the geometric, we will have that;
Hence, the 9th term of the geometric progression is 1953125
Possibility or highly chances are that the five is going to get pulled because there are two of the fives and five isn't rare, so from the number 9,484,558 the number that would possibly be picked is one of the fives because there are two of the fives and five isn't rare if there is two of them, so the digit that would probably be pulled is one of the fives
