This is a positive slope. If it goes up it’s a positive and if it goes down it’s a negative.
Answer:
8%
Step-by-step explanation:
Interest = $112
Principal = $1400
Rate = Percentage Per Year
Time = 1 Year
I = PRT
Multiply everything together...
Divide both sides by 1400.
Simplify.
Simplify the fraction. Feel free to flip the equation (Put the R on the right side of the = instead of the left).
Change the fraction into a decimal.
Turn this number into a percentage and we have our answer:
R = 8% per year
The exponential equation represents an exponential growth because the rate of decay is 1.02 which is greater than 1.
y = 90(1.02)^x
The general form equation is:
y(x)= a(1+r)^x such that r is the decay percent.
on comparing,
1 + r = 1.02
r = 1.02 - 1
r = 0.02
converting into percent
r = 0.02 * 100
r = 2%.
Hence the exponential growth is 2%.
