The factors are all the possible things you would multiply to get the number. So finding the 2 middle numbers, in this case is 21 and 28 and multiplying them, you get 588. If you're not sure if that's right, take the number on the left or right of the 2 middle numbers, 14 and 42. The product of these 2 numbers are also 588. So your number is 588.
Answer:

Step-by-step explanation:
Answer:
a) 
b) When t = 10, Q = 7.845.
Step-by-step explanation:
The value of a quantity after t years is given by the following formula:
In which 
is the initial quantity and r is the rate that it changes. If it increases, r is positive. If it decreases, r is negative.
a) Write a formula for Q as a function of t.
The initial value of a quantity Q (at year t = 0) is 112.8.
This means that 
.
The quantity is decreasing by 23.4% per year.
This means that 
So
b) What is the value of Q when t = 10?
This is Q(10).
When t = 10, Q = 7.845.
Answer:
The answer is B. It often helps to look at the desmos website to input the graphs.
Step-by-step explanation:
You can see that the points (4,13) intersect the graphs y = 2/5x+23 as well as be perpendicular to y=2/5x-5.
