The sum of a geometric sequence is:
s(n)=a(1-r^n)/(1-r), a=initial term and r=common ration so
s(n)=20(1-0.25^n)/(1-0.25)
s(5)=20(1-0.25^5)/(0.75)
s(5)=26.640625
Answer:
Description
Step-by-step explanation:
1. Factor 2x^2+11x+12 -> (2x+3)(x+4)
x=-4, -3/2
Both numbers are rational numbers as both can be expressed in the form in a quotient with integer values.
2. If discriminant is negative, then solutions are imaginary, meaning that the discriminant is less than 0, so you can set up this equation.
11^2 - 4(a)(12) < 0
121 - 48a < 0
a>121/48
The closest integer to 121/48 (~2.52) such that it satisfies the above conditions is 3, so the lowest value for a is 3.

Answer:
sorry PLS the question is not clear I think U missed some parts
Answer:
$72,000
Step-by-step explanation:
If we take 60,000 and then take 20 percent of it, we get 12,000. Then we add 12,000 to 60,000 and it gives us 72,000.
Answer: Choice A
Step-by-step explanation:
It's choice A since the absolute value of -3 is 3 since it's in parentheses. 45 represents 45 dollars also deposited into the bank account.
Hope this helps!
