You can do some rounding and reach that 450 goes into 50 9 times, so this won't be that far. So, 51 * 9 is equal to 459, and there is a remainder of 11. So, you can put it in mixed fraction form as:
And
that's your answer!
A quadratic with roots at 8 and 5 is f(x) = x^2 +12x + 20
In order to find an equation given roots you can create statements that equal 0 in order to create parenthesis. For instance we know x = 8 at one point. So, we can solve that to equal 0.
x = -2 ----> add 2 to both sides
x + 2 = 0
We can do the same for the other zero.
x = -10 ----> add 10 to both sides
x + 10 = 0
Now that we have both of these, we can multiply these two things together. This will give us the function we need.
f(x) = (x + 2)(x + 10)
f(x) = x^2 + 10x + 2x + 20
f(x) = x^2 + 12x + 20
Answer: 
Step-by-step explanation:
You know that the given function is:
You know that you must evaluate this function for 
.
Then, to evaluate the function for , you need to substitute this value into the given function and simplify it.
Therefore, you get:
So, the answer is:
