Answer:
Given that:
The equation for the future value of a deposit earning compound interest is equation:
.....[1]
where,
P = the initial deposit
t = years invested
r = rate at which interest is compounded annually
.
n = number of times the interest is compounded per year
As per the statement:
After 10 years, a $2,000-dollar investment compounded annually has grown to $3600.
⇒P = $2000 and V(t) = $3600
Substitute in [1] we have;
Divide both sides by 2000 we have;
Taking log base 10 both sides we have;
⇒
Divide both sides by 10 we have;
⇒
Simplify":
Subtract 1 from both sides we have;
or
r = 0.06 = 6%
Therefore, 6% is the interest rate to the nearest whole-number percent
Exponential functions can be expressed as:
f=ir^t, f=final value, i=initial value, r=rate or common ratio, t=term number or "time" when it is fractional...In this case we have:
f=100((100-11)/100)^x
f=100(0.89)^x and we want to solve for when f=15 so
15=100(0.89)^x
Answer:
6%

There are 6 out of the 100 blocks shaded in
Six hundred ninty three thousand, five thousand six hundred ninty nine
Three hundred fourty thousand two thousand and eighty nine
I’m confused on the comma for the last 2?
Answer:
-4 x 15 = -60 12 x 21 = 252
-4 x 4 = -16 12 x 63 = 756
-4 x 5 = -20 12 x 42 = 504
-60 + -16 + -20 = -96 252 - 756 + 504 = 0
Step-by-step explanation:
distributive property on both sides
