Perimeter of Rectangle = 2W + 2L
20 = 2W + 2L = 4 sides
20/4 = 5
5' × 5'
An exponential model can be described by the function
where: a is the initial population or the starting number, b is the base and x is the number of periods elapsed.
When the base of an exponential model is greater than 1 it is called a growth factor, but when it is less than 1 it is called a decay factor.
Given the exponential model
n is the final output of the exponential model, 20.5 is the starting number, 0.6394 is the base and t is the number of periods/time elapsed.
Here, the base is 0.6394 which is less than 1, hence a decay factor.
Therefore, <span>the
base, b, of the exponential model is 0.6394; It is a
decay factor.</span>
Answer:
0.5 is the answer of this question

Answer:
11x^2 −6x−9
Step-by-step explanation:
9x^2 – 10x + 1 - ( -2x^2) + 4x – 10.
The opposite of −2x^2 is 2x^2
9x^2
−10x+1+2x
^2
+4x−10
Combine 9x^2 and 2x^2 to get 11x^2
.
11x^2
−10x+1+4x−10
Combine −10x and 4x to get −6x.
11x^2
−6x+1−10
Subtract 10 from 1 to get −9.
11x^2 −6x−9
