.25 • 13 = $3.25 (13 is the # of quarters)
$3.25+ 2(.10) = .20 (2 dimes)
$3.25+.20= $3.45
If I assume you meant

Then the answer is at 4 minutes. This is just the vertex form of the parabola which is
where (h,k) is the vertex. h = 4 so the vertex is at 4 in the x-axis, or in the context of the problem it means at 4 minutes.
Answer:
We conclude the exponential form will be:

Step-by-step explanation:
Given the logarithmic equation

Writing the logarithmic equation in exponential form.
We know that
→ 
Let us write the logarithmic equation in exponential form using the expression above
a = 9
b = 729
x = 3
Thus, we conclude the exponential form will be:

To answer this, we assume that the can is in cylindrical shape. The of its label would correspond to an area of a rectangle where the length would be the circumference of the base of the can. We calculate as follows:
C = 2πr = 2π(4) = 8π = L
A = LH = 8π(H) = 302
H = 12 cm
Hope this answers the question. Have a nice day.
