I believe that the answer to the question provided above is that <span>the maximum total area that 450 cm of string can enclose if it is used to form the perimeters of two is area = 12 656.25 sqr cm. 450/4 = x . x^2 = area</span>
Hope my answer would be a great help for you. If you have more questions feel free to ask here at Brainly.
Answer:
The formation of the equation is odd, but I assume it's supposed to be:
4k - 10k = -8k
-6k = -8k
-6k + 8k = -8k + 8k
2k = 0
=
k = 0
The investment that increase by a factor of 5 in 20 years, has a growth of 8.38% per year.
<h3>What is an
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 multiplication factor.
Given that an investment increasing in value exponentially, to increase by a factor of 5 in 20 years. Hence:
Factor per year =
Growth per year = 1.0838 - 1 = 0.0838 = 8.38%
The investment that increase by a factor of 5 in 20 years, has a growth of 8.38% per year.
