Answer:
The correct answer is f(x)
Step-by-step explanation:
The answer is f(x) because is the result of the quadratic sum, once the function is evaluated. Example:
Let be x= 2
Then f(2)= 4+2+1=7
Therefore the output is f(2) which is equal to 7.
Answer:
The worth of the TV after 3 years is £809.90208
Step-by-step explanation:
The answer to given question can be found from the anual depreciation formula and solving for the Future Value (F. V.) of the machine
The given parameters of the TV are;
The amount at which Collin buys the TV, P = £720
The rate at which the TV depreciates at, R = 4%
The number of years the depreciation is applied, T = 3 years
The amount the TV is worth after three years, 'A', is given as follows;

By plugging in the known values, we have;

The amount the TV is worth after three years, A = £809.90208
Derek ran less than 6 miles. If the race is 6 miles, and he only ran 3/8, he ran less than a half of the race. If he didn't finish the race of 6 miles, he couldn't possibly have run 6 miles.
Answer: 9
Step-by-step explanation:
Formula : Mean = 
Given: 5 students participated in a push-up competition.
The amount of push-ups each student completed is listed: 12, 7, 10, 11,5.
Mean = 

Hence, the mean number of push-ups = 9
Since r is being divided by N, we need to multiply both sides by N.
We are left with R + T = 4v/n
Now, we subtract T from each side. The equation is now R = 4V/N - T
We have now solved for R.
