Answer:
Step-by-step explanation:
I = (P × R × T)/100
P = $72.80, R = 4 1/4 = 17/4, T = 2yrs
I = (72.8 × 17/4 × 2)/100
I = $6.19
1285.37
You can use the formula for compound interest:
P(1+R)^t
P = the principle, the amount of money
(1+R) = the rate, (%) as a decimal plus 1
^t = to the power of the number of years
Substitute the values:
750(1+0.08)^7
750(1.08)^7
1285.37
Step-by-step explanation:
Answer:
870
Step-by-step explanation:
6190-5320=870
(f+g)(x)=0 means
f(x)+g(x)=0
x²-2+6x+4=0
x²+6x+2=0
using math and quadratic formula
x=-3+√7 or -3-√7
