Answer:
Step-by-step explanation:
The compound interest formula is given by:
Where A(t) is the amount of money in the account after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the number of years the money is invested or borrowed for.
For this problem, we have that:
The investment is compounded monthly. There are 12 months in a year. So 
The interest rate is 3%. So 
.
So
The amount of money in her account after t years is:
The answer is D because to find the slope of a line that is perpendicular to another, you have to find the opposite reciprocal. so here the slope would be -1/4. now, take that slope and put it into an equation. like the following:
now to find b you must insert the points into the equation (plug in 4 for x, and 15 for y).
b then equals 16. so, the answer is D.

Answer:
Step-by-step explanation:
Average rate of change is Δy / Δx.
For f(x):
[ f(1) - f(0) ] / (1 - 0)
(1 - 3) / (1 - 0)
-2
For g(x):
[ g(1) - g(0) ] / (1 - 0)
(4 - 3) / (1 - 0)
1
Answer:
38174:54*3*0.40
Step-by-step explanation:
1. calculate how much per week by
38174:54
2. than in 3 weeks
38174:54*3
3. than 40 percent of that
