Answer:
The answer is below
Step-by-step explanation:
a) The baseball player leaps into the air with an initial velocity of 14 feet per second. This means that the player leaps from the ground, the initial height is therefore zero.
The height (y) is given by the formula:
y(t) = ut - (1/2)gt² + initial heigth
u = initial velocity = 14 ft/s, t = time taken, g = acceleration due to gravity = 32 ft/s². Substituting:
y(t) = 14t - (1/2) * 32 *t² + 0
y(t) = 14t - 16t²
b) when the player is on the ground, the height = 0. hence:
0 = 14t - 16t²
16t² - 14t = 0
t(16t - 14) = 0
t = 0 or 16t - 14 = 0
t = 0 or 16t = 14
t =0 or t = 0.875
Hence t = 0.875 seconds
c) The domain is the set of possible values for the time. Hence:
Domain = (0, 0.875] = 0 < t ≤ 0.875
first subtract 2 from - 5 which is 7 then subtract 3-2 then you would get x = 7 that would be my guess.
If you break down the beginning part, its 150 ÷ 3 = 50, so that means each class took 50 minutes. Not only that, you get your 'Time/Minutes per Class'. From there, you can multiply 50 by 5 and get 250 minutes, or 4 hours and 10 minutes.
In short: 250 minutes or 4 hours and 10 minutes.
The ratio between 28,000 and 14 is 2000 : 1
<h3>How to determine the ratio?</h3>
The numbers are given as:
28,000 and 14
Express as ratio
Ratio = 28000 : 14
Divide each number by 14
Ratio = 2000 : 1
Hence, the ratio between 28,000 and 14 is 2000 : 1
