10+10 because the sum of their squares is 200, if you choose any other pair, the sum of their squares will be higher.
I cant see :( Try another picture even though this might be too late I'm sorry.
The answer is {4, 6, 8, 10, 12} - or B
Answer:
Required logarithmic function is :
![f\left(x\right)=\log_3\left(x\right)](https://tex.z-dn.net/?f=f%5Cleft%28x%5Cright%29%3D%5Clog_3%5Cleft%28x%5Cright%29)
Step-by-step explanation:
We have been fiven that table for the logarithmic function is:
x f(x)
9 2
27 3
81 4
which can be rewritten as:
x f(x)
3^2 2
3^3 3
3^4 4
Which are basically powers of 3
So we can use logarithmic function as
![\log_3\left(9\right)=\log_3\left(3^2\right)=2\log_3\left(3\right)=2(1)=2](https://tex.z-dn.net/?f=%5Clog_3%5Cleft%289%5Cright%29%3D%5Clog_3%5Cleft%283%5E2%5Cright%29%3D2%5Clog_3%5Cleft%283%5Cright%29%3D2%281%29%3D2)
Hence required logarithmic function is :
![f\left(x\right)=\log_3\left(x\right)](https://tex.z-dn.net/?f=f%5Cleft%28x%5Cright%29%3D%5Clog_3%5Cleft%28x%5Cright%29)
Answer:
where t is in years
Step-by-step explanation:
I'm going to assume that the expectation that Cameron has is the amount of money after t years.
We can use the simple interest formula
where A is the final amount, P is the principal, r is the rate, and t is time.
We can plug in 10,000 for P and 0.05 for r, giving us
![A = 10,000(1.05t)](https://tex.z-dn.net/?f=A%20%3D%2010%2C000%281.05t%29)
