The time it take the ball to reach 156feet above the ground level is 0.5 secs and 5.5 seconds
Functions and valuesGiven the height of the ball expressed by the function below;
h = -16t^2 + 96t + 112
where
t is the time in seconds
If the car is 156ft above the ground, hence
Substitute
-16t^2 + 96t + 112 = 156
Multiply through by -1
16t^2 - 96t - 112 = -156
16t^2 - 96t - 112 + 156 = 0
16t^2 - 96t + 44 = 0
4t^2 - 24t + 11 = 0
Factorize
On factorizing, the positive value of "t" is 0.5 secs and 5.5 seconds
Hence the time it take the ball to reach 156feet above the ground level is 0.5 secs and 5.5 seconds

The coach for a basketball team wants to buy new shoes for her 12 players.
Super Sports is offering a 20% discount on each pair of shoes, which were originally
priced $72.50. A 6.5% sales tax will be applied to the discounted price.
The same shoes are also available on Double Dribble's web site for $54.75. A
9% processing fee will be applied to the cost of the shoes, plus a shipping fee of
$5.99 for each pair.
What is the difference in the total costs of the 12 pairs of shoes between the two
stores?
Using proportions, it is found that the difference in the total costs of the 12 pairs of shoes between the two stores is of $46.77.
What is a proportion?A proportion is a fraction of a total amount.
At Super Sports, each pair of shoes costs $72.50, with a discount of 20%(multiplication by 0.8) and a sales tax of 6.5%(multiplication by 1.065). Hence, the total cost of the 12 pairs is given by:
Cs = 12 x 72.50 x 0.8 x 1.065 = $741.24.
At Double Dribble, each shoe costs $54.75, plus a 9% processing free(multiplication by 1.09), plus a shipping fee of $5.99 for each pair, hence the total cost is given by:
Cd = 12 x (1.09 x 54.75 + 5.99) = $788.01.
The difference is given by:
$788.01 - $741.24 = $46.77.

The population sizes of many animal species rise and fall over time. Suppose that the population size of a certain species can be modeled by the following.
[tex]p(t) = 4096 - 1269cos(\frac{2\pi }{11} t)[/tex]
In this equation, p(t) represents the total population size and t is the time (in years). Suppose we start at t = 0 years.
During the first 11 years, when will the population size be 4700?
Do not round any intermediate computations, and round your answer(s) to the nearest hundredth of a year. (If there is more than one answer, enter additional answers with the "or" button.)
There are two answers
Solving the trigonometric equation, it is found that during the first 11 years, the population size will be of 4700 in 3.62 and 7.24 years.
What is the trigonometric equation for the population?It is given by:
[tex]p(t) = 4096 - 1269\cos{\left(\frac{2\pi}{11}t\right)}[/tex]
It will be of 4700 when p(t) = 4700, hence:
[tex]p(t) = 4096 - 1269\cos{\left(\frac{2\pi}{11}t\right)}[/tex]
[tex]4700 = 4096 - 1269\cos{\left(\frac{2\pi}{11}t\right)}[/tex]
[tex]604 = - 1269\cos{\left(\frac{2\pi}{11}t\right)}[/tex]
[tex]\cos{\left(\frac{2\pi}{11}t\right)} = -\frac{604}{1269}[/tex]
[tex]\cos{\left(\frac{2\pi}{11}t\right)} = -0.47596532702[/tex]
[tex]\cos^{-1}{\cos{\left(\frac{2\pi}{11}t\right)}} = cos^{-1}{-0.47596532702}[/tex]
Then:
[tex]\frac{2\pi}{11}t = 2.06685766[/tex]
[tex]t = \frac{11 \times 2.06685766}{2\pi}[/tex]
[tex]t = 3.62k, k = 1, 2, ...[/tex]
Thus:
t = 3.62 x 1 = 3.62
t = 3.62 x 2 = 7.24.
The population size will be of 4700 in 3.62 and 7.24 years.
