Step-by-step explanation:
add or subtract the groups in order to answer them... or use a calculator for the job
Answer:
Step-by-step explanation:
an=4=a1+(n-1)*d=0.25+(n-1)*d
so (n-1)*d=4-0.25=3.75
Sn=a1*n+(n-1)*d
a1*n+3.75=8.5
0.25*n+3.75=8.5
-3.75 -3.75
0.25*n=8.5-3.75=4.75
n=4.75:0.25
n=19
so a19=a1+(19-1)*d=4
0.25+18*d=4
-0.25 -0.25
18*d=3.75
d=3.75/18
d=0.208
so a2=a1+0.208=0.25+0.208=0.458
a2=0.458
A=b+99
a+b=6565
substitute: b+99 + b =6565
b=3233
a=3332
Answer:
Red: y=(x+6)^2-1
Blue: y=-(x+3)^2+1
Green: y=(x^2-1)
Orange: y=-(x-3)^2+1
Purple: y=(x-6)^2-1
Step-by-step explanation:
Use Desmos to check
The number of years (n) that the deposit stayed in his balance is given by: 65 - 18 = 47 years.
The future value (FV) of a deposit (P), deposited at an interest rate of r% compounded yearly for n years is given by

Given that <span>Jamal deposits P = $1000 into a savings account on for n = 47years at 2% interest compounded yearly, the amount in his bank account at the end of the period is given by
