Is there anything else to the problem
Answer:
an = −1,171,875(1/5)^n-1
Step-by-step explanation:
The given sequence is geometric sequence since they have the same common ratio r. The nth term of a geometric sequence is expressed as;
an = ar^n-1
n is the number of terms
r is the common ratio
a is the first term
From the sequence;
a = −1,171,875
r = −234,375 /−1,171,875 = -46,875/−234,375 = 0.2
r = 1/5
Substitute the values in the formula;
an = −1,171,875(1/5)^n-1
Hence the required explicit formula is an = −1,171,875(1/5)^n-1
Answer:She ordered pipe cleaners more
Step-by-step explanation:
Answer:
$5333.33
Step-by-step explanation:
x is the unknown, but we know that 22.5% of x equals 1,200. So we use this information to set up an equation.
x * 22.5% = 1,200
Now we can solve for x by dividing both sides by 22.5%
x = 5333.33
The dollar value of the items she sold was $5333.33
Answer:
5 months
ROI = 3.75 %
Step-by-step explanation:
Since,
The simple interest formula,
Where,
P = Principal amount,
r = rate per period ( in decimal )
t = number of periods,
Here, P = 800, r = 9% = 0.09,
If A is the future amount,
We have, A = 830
I = A - P = 830 - 800 = 30
By substituting the values in the above formula,
Hence, it will take 5 months. ( 1 year = 12 months )
Now,
