Answer:
2x^2 + 4x - 64
Step-by-step explanation:
it is telling us to add the functions together so we use this equation:
2x^2 + 7x - 5 + (-8^2) - 3x + 5
after combining like terms we get
2x^2 + 4x -8^2
and then lastly we square the -8 and get
2x^2 + 4x - 64
Answer:
No, I got 18
Step-by-step explanation:
180-78=102
180-11-49=120
180-120=60
x=180-102-60=18
3 more then a number squared......
n^2 + 3
1) Quaterly interes = 3% / 4 = 0.03 / 4
2) Values:
after 1 quarter: 2000 (1 + 0.03/4)
after 2 quarters: 2000 (1 + 0.03/4)^2
after 3 quarters: 2000 (1 + 0.03/40^4
after 4 quarters = 2000 (1 + 0.03/4)^4
You could have used the future value formula directly:
A = C * (1 + r/n) ^ n*t
where r = 3% = 0.03
n = number of periods in a year: 4
t = number of years = 1
C = initial investment = 20000
=> A = 2000 (1 + 0.03/4)^4
Answer: option D. A = 2000 ( 1 + 0.03 /4) 4
