Answer:
{0,6}
Step-by-step explanation:
-2x^2+12x = 0
Factor out a -2x
-2x(x-6) =0
Using the zero product property
-2x = 0 and x-6=0
-2x = 0
Divide by -2
-2x/-2 = 0/-2
x=0
x-6=0
Add 6 to each side
x-6+6 =0+6
x=6
The solutions are 0 and 6
Answer:
$2355.06
Step-by-step explanation:
Use the compound interest formula, filling in the numbers you know. Then solve for the number you don't know.
A = P(1 +r/n)^(nt)
where A is the account balance, P is the amount invested, r is the annual rate, n is the number of times per year interest is compounded, and t is the number of years.
Filling in the given values, we have ...
4000 = P(1 +.053/52)^(52·10) = P(1.6984738)
P = 4000/1.6984738 ≈ 2355.06
You would need to deposit $2355.06 in order to have $4000 in 10 years.

Answer:
If Ted can clear a football field of debris in 3 hours, in one hour they will have cleared 1/3 of it.
If Jacob can clear a football field of debris in 2 hours, in one hour they will have cleared 1/2 of it.
So if they work together, they will clear 1/2 + 1/3, which is 5/6, in one hour.
So the equation we get is 5/6*x = 1 and if we divide both sides by 5/6 we get that x = 1.2 hours
