Answer:
D = -1, -1, 2, 5
R = 0, 2, 3, 7
✅It is NOT A FUNCTION
Step-by-step explanation:
D (Domain) = input values (x-values)
D = -1, -1, 2, 5
R (Range) = output values
R = 0, 2, 3, 7
✅It is not a function because an x-value, -1, has two different y-values, 7 and 2, assigned to it.
Every 56 seconds, the radioactive substance is divided in half.
224 / 56 = 4
We need to cut the substance in half 4 times.
896 / 2 = 448
448 / 2 = 224
224 / 2 = 112
112 / 2 = 56
After 224 seconds, there will be 56 grams of the radioactive substance left over

Answer:
$13,916.24
Step-by-step explanation:
First, we need to find the value of the CD at maturity.
A = P(1 +rt) . . . . simple interest rate r for t years
A = $2500(1 +0.085·3) = $2500×1.255 = $3137.50
__
Now, we can find the value of the account with compound interest.
A = P(1 +r)^t . . . . . rate r compounded annually for t years
A = $3137.50 × 1.18^9 = $13,916.24
The mutual fund was worth $13,916.24 after 9 years.
