Answer:
x = 9
y = -10
Step-by-step explanation:
Answer:
The interest is compounded quarterly.
The effective annual interest rate on the account is 8.60%.
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:
Where A(t) is the amount of money 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 year and t is the time in years for which the money is invested or borrowed.
We are given:
Comparing to the general formula.
From the last one:
Which means 4 compoundings per year. This means that the interest is compounded quarterly.
Interest rate:
Since n = 4.
So the interest rate is of 8.60%.
(2-7i)(9+5i)
18+10i-81i-35i^2
The answer is 35i^2 - 71i +18
Y - 1 = 2(x - 2)
y - 1 = 2x - 4
y = 2x - 4 + 1
y = 2x - 3
So first thing you look for is whichever graph has a y-intercept at y = - 3. Any of the graphs that DON'T have a y-intercept at (0, - 3) can be eliminated. The only one that does is the first graph so...
Your answer is the first graph.
You would need 10 cups since you need 3 cups for every one muffin (24/8=3)
(30/3=10)
