Answer:
The answer to your question is: f(0) = 7.07 units
Step-by-step explanation:
f(x) = 2(x)² +5√(x + 2) function
f(0) = 2(0)² +5√(0 + 2) substitution
f(0) = 0 + 5√2 simplify
f(0) = 5√2
f(0) = 7.07 units
Answer:

It should look like 2(-6)-5(-6)=18
Answer:
$265.07
Step-by-step explanation:
The formula for the future value of an annuity is applicable.
A = P((1+r)^n-1)/r . . . . where r is the monthly interest rate and n is the number of months. P is the monthly payment, and A is the amount of the future value.
800 = P(1.006^3 -1)/(.006) = 3.018036P
P = 800/3.018036 ≈ 265.07
Sarafina's monthly payments need to be $265.07.
_____
This is about $1.60 less than the 266.67 she would deposit if she simply divided the desired balance by the number of months.
Because this number is rounded down, Sarafina will have a balance after 3 months of $799.99.
