Answer:
Step-by-step explanation:
Your exponential formula is in the form y = ab^x. In this form, the coefficient 'a' is the initial value, the y-intercept, the value when x=0. The value 'b' is the growth factor, which is 1 more than the growth rate per increment of x. This problem is asking for the growth rate to be expressed as a percentage.
__
Given p(x) = 78500(1.02^x), we can compare to the exponential function form to see that ...
- a = 78,500
- b = 1.02 = 1 +0.02 = 1 +2%
The value of x is zero in the year 2000, so the population that year is ...
p(0) = a = 78,500
The increase per year is the value of 'b' with 1 subtracted:
growth rate = 2% per year
Answer:
a: x = -4
b: x = 4
c: y = 4
d: y = -2
e: y = -3/4x + 1

Answer:
1176
Step-by-step explanation:
First, calculate the volume as if it was a full rectangle.
Volume formula:
length x width x height
16 x 6 x 21 = 2016 (this is the volume if this was a full rectangle)
Now to calculate the size of the missing part we do the same thing
10 x 6 x 14 = 840
To work out the volume of this shape, we need to subtract the volume of the missing part from the volume of the rectangle
2016 - 840 = 1176
I hope this helped :-)
Answer:
c = 15t
Step-by-step explanation:
Given that:
Unit cost of Ticket = $15
Total cost = unit cost * number of tickets purchased
Total cost = c
Number of tickets purchased = t
C = $15 * t
c = 15t
