Answer:
Step-by-step explanation:
The formula you need for this is
where
A(t) is the amount after a certain number of years has gone by,
P is the initial deposit,
r is the interest rate in decimal form,
n is the number of compoundings done per year, and
t is the amount of time in years.
For us,
A(t) = 11900
P is 250
r is .048
n is 12 (there are 12 months in a year)
t is our unknown. Filling in:
which simplifies a bit to
. Now we'll divide both sides by 250:
and then take the natural log of both sides to bring that t down out front:
and then
ln(47.6) = 12t ln(1.004). Now divide both sides by ln(1.004) to isolate the 12t:
967.6383216 = 12t and divide both sides by `12 to get
t = 80.6 months which is 6.7 years
Answer:
2*4ⁿ
Step-by-step explanation:
Answer:
by u meant 32n^4, then the answer is 2n^4
Step-by-step explanation:
first find the gcf of the coefficient
32 and 34
their gcf is 2, because they're both even but have no other common factor, so it is 2
then for the variables
n^4 and n^5
their gcf is n^4. you can tell by dividing each term by n^4
n^4 / n^ 4 = 1
n^5 / n^4 = n
so then 2 * n^4 is 2n^4
Answer:
The length is 56 and the width is 54.
Step-by-step explanation:
The perimeter of a rectangle is 2x+2y (width and length on both sides). so 2x+2y=220. Also x=y-2, because the width is 2 feet less than the length. Fill x=y-2 in 2x+2y=220 and we get 2(y-2)+2y=220. 2y-4+2y=220. 4y=216. y=54. Fill in y=54 in 2x+2y=220 and we get 2x+2(54)=220. 2x=220-2(54)=112. x=56.
Answer:
4 2/3
Step-by-step explanation:
(m-4) (3m-2)=0
Use the zero product property to find the zeros
m-4 = 0 3m-2 =0
m =4 3m =2
m = 2/3
We want the sum of the zero's
4+ 2/3
4 2/3
