The exponential function used to represent the profit after t years is
<h3>Exponential function</h3>
An exponential function is in the form:
y = abˣ
where y, x are variables, a is the initial value of y, and b is the multiplier.
Let y represent the profit after t years.
Since the profit on a given day is $550 and is growing exponentially at a rate of 60% per year. Hence:
- a = 550
- b = 100% + 50% = 1.6
The profit function is given by:

Six people stayed at home because 10+4=14 meaning every one is home but 8 people left the house meaning 14-8=6
therefore 6 people stayed home

It would be 9 ones or 4 hundred thousands
Answer:
f(8) = 192
Explanation:
f(x) varies directly with x²
This means that:
f(x) = kx²
where k is the constant of proportionality.
Now, we are given that:
f(x) = 75 at x = 5
Substitute to get k as follows:
f(x) = kx²
75 = k(5)²
75 = 25k
k = 3
This means that the equation is:
f(x) = 3x²
Now, to find f(x) at x = 8, all we have to do is substitute with x = 8 in the equation as follows:
f(8) = 3*(8)²
f(8) = 3*64
f(8) = 192
Hope this helps :)
