Answer:
Option C is the answer.
Step-by-step explanation:
A florist sale is for it's first month is represented by the equation y = 168x + 8
Here y represents the sales in dollars and x represents number of days.
Now we have to calculate the number of days it took to reach $3200 in sales.
For this we will substitute $3200 in place of y and find the value of x by solving the equation.
3200 = 168x + 8
168x = 3200 - 8 = 3192
Therefore Option C. is the correct option.

<u>Answer: </u>
An inlet pipe on a swimming pool can be used to fill the pool in 33 hours. Time it will take to fill the pool = 748 hrs
<u>Solution: </u>
Let x = time it will take to fill the pool
= work rate of inlet pipe
= work rate of drain pipe
Using the formulae
Volume of flow=work rate time
Let us assume complete time of pool to fill = 1
Remaining fraction of pool to be filled =
Time it will take to fill the pool = 748 hrs

<u>Quadratic Function</u>
Standard Form of Quadratic Function
The standard representation of a quadratic function is:
where a,b, and c are constants.
When the zeros of f (x1 and x2) are given, it can be written as:
f(x)=a(x-x1)(x-x2)
Where a is a constant called the leading coefficient.
We are given the two roots of f: x1=-3 and x2=4, thus:
f(x)=a(x+3)(x-4)
We also know that f(5)=8, thus:
f(5)=a(5+3)(5-4)=8
Operating:
a(8)(1)=8
Solving:
a=1
The function is:
f(x)=1(x+3)(x-4)
Operating:
