6(4a^2+11)- 13(3a-2a^2)-28
24a² + 66 - 39a +26a² - 28
50a² - 39a + 38
Answer:
<u>$4,680</u>
Step-by-step explanation:
<u>Rate</u> : 10 dollars a week
- Per year : 10 x 52 = $520
- 9 x 520 = $4,680
You will have saved up <u>$4,680</u> in 9 years.
6,000 square meters times ten equals 60,000 square meters.
Answer: Option C: 0.03125
Step-by-step explanation:
we have an exponential equation, so we have:
f(x) = A*r^x
we have that:
f(1) = A*r^1 = A*r = 0.5
f(2) = A*r^2 = 0.25
f(3) = A*r^3 = 0.125
f(4) = A*r^4 = 0.0625
f(5) = A*r^5 = ?
we want to find the value f(5)
first, let's take the quotient:
f(2)/f(1) = (A*r^2)/(A*r) = r = 0.25/0.5 = 0.5.
then we have:
f(x) = A*0.5^x
and f(1) = A*0.5 = 0.5
then A = 0.5/0.5 = 1.
now we know that our function is f(x) = 0.5^x.
then, if we want to find f(5) we have:
f(5) = 0.5^5 = 0.03125
Then the correct option is option c.
