To write the function to show the weekly growth rate of population , we first find the weekly growth rate by dividing yearly growth rate by 52 ( as there are 52 weeks in an year)
Given function is ,
or
To convert in weekly growth rate , divide 0.016 by 52
So formula for weekly growth rate of population is
or
And the weekly growth rate = 
I think its the second one. So B. because its up 3 on the X-Axis and then the rest are wrong
Answer:
1. 
2. 
Step-by-step explanation:
When you multiply radicals, you do the following
with that in mind
1.
here we don't need to multiply 16 times 5, because 16 = 4^2 and take the square root of it, gives you 4
2.
Answer:
x=√2, x=-√2, x= 3 and x=-3
Step-by-step explanation:
We need to solve the equation x^4 - 11x^2+18=0
We can replace x^4 = u^2 and x^2 = u
So, the equation will become
u^2 -11u+18 = 0
Factorizing the above equation:
u^2 -9u-2u+18 =0
u(u-9)-2(u-9)=0
(u-2)(u-9)=0
u=2, u=9
As, u = x^2, Putting back the value:
x^2 =2 , x^2 =9
taking square roots:
√x^2 =√2 ,√x^2=√9
x=±√2 , x = ±3
so, x=√2, x=-√2, x= 3 and x=-3
