Answer:
width=x
length=5x
area= 300ft2
area=lxb
300=5x(x)
300=5x^2
x^2=60
x=7.74
7.74(5)=38.7
dimensions are 38.7ft by 7.74 ft

The general equation for exponential growth can be written as:
![x_{t} = x_{0} (1+r)^{t}](https://tex.z-dn.net/?f=%20x_%7Bt%7D%20%3D%20x_%7B0%7D%20%281%2Br%29%5E%7Bt%7D)
where r is the growth rate.
Plugging in the given values, we get:
![1100=1000(1+r)^{3}](https://tex.z-dn.net/?f=1100%3D1000%281%2Br%29%5E%7B3%7D)
Therefore
![(1+r)^{3}=1.1](https://tex.z-dn.net/?f=%281%2Br%29%5E%7B3%7D%3D1.1)
giving
![1+r= \sqrt[3]{1.1} =1.0323](https://tex.z-dn.net/?f=1%2Br%3D%20%5Csqrt%5B3%5D%7B1.1%7D%20%3D1.0323)
The predicted number of bacteria after 17 hours is given by:
For this case we must find
![(f + g) (x).](https://tex.z-dn.net/?f=%28f%20%2B%20g%29%20%28x%29.)
By definition we have to:
![(f + g) (x) = f (x) + g (x)](https://tex.z-dn.net/?f=%28f%20%2B%20g%29%20%28x%29%20%3D%20f%20%28x%29%20%2B%20g%20%28x%29)
We have the following functions:
![f (x) = 5x ^ 3-2\\g (x) = 2x + 1](https://tex.z-dn.net/?f=f%20%28x%29%20%3D%205x%20%5E%203-2%5C%5Cg%20%28x%29%20%3D%202x%20%2B%201)
Now, applying the given definition, we have:
![(f + g) (x) = 5x ^ 3-2 + 2x + 1\\(f + g) (x) = 5x ^ 3 + 2x-1](https://tex.z-dn.net/?f=%28f%20%2B%20g%29%20%28x%29%20%3D%205x%20%5E%203-2%20%2B%202x%20%2B%201%5C%5C%28f%20%2B%20g%29%20%28x%29%20%3D%205x%20%5E%203%20%2B%202x-1)
Answer:
![(f + g) (x) = 5x ^ 3 + 2x-1](https://tex.z-dn.net/?f=%28f%20%2B%20g%29%20%28x%29%20%3D%205x%20%5E%203%20%2B%202x-1)
