Answer:
the value of x-1/x is given down
Step-by-step explanation:
=(x+1/x)²=x²+1/x²+2
=(5)²=x²+1/x²+2
=x²+1/x²=25-2
=x²+1/x²=23 this is the answer
if u ask there how 25 came means there (5)² is that u should multiply 5×5 and u will get 25bas the answer
The interest is compounded quarterly because the formula is
A=p (1+r/k)^kt
A it's 18810.67 but I will assume it's unknown ?
P present value 7350
R interest rate 0.045
K compounded quarterly 4
Now solve the formula as the interest is compoundedquarterly
A=7,350×(1+0.045÷4)^(4×21)
A=18,810.67
So the answer is quarterly
