The future value of a monthly deposit A=125.30 at annual interest i=0.015 per annum for n=35 years compounded monthly is given by
FV=A((1+i/12)^(12*n)-1)/(i/12)
=125.30(1+0.015/12)^(12*35)/(0.015/12)
=$69156.05
The annuity formula is given by
Payment = r(PV)/(1-(1+r)^(-n))
where
r=interest rate per period = 0.015/12
PV= $69156.05
n=20*12=240
so
Payment = (0.015/12)<span>69156.05/(1-(1+0.015/12)^(-240))
= $333.71 per month.</span>
At most, 20. 20 is the greatest common factor of all numbers.
I believe it is c because it is definitly not biased because they were selected at random. And d. Is incorrect
Answer:
Step-by-step explanation:
The given quadratic equation is expressed as
x² - 6x - 40 = 0
The equation is already in the standard form of ax² + bx + c
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the equation given,
a = 1
b = - 6
c = - 40
Therefore,
x = [- - 6 ± √(- 6² - 4 × 1 × - 40)]/2 × 1
x = [- 6 ± √(36 - - 160)]/2
x = [- 6 ± √196]/2
x = (- 6 + 14)/2 or x = (- 6 - 14)/2
x = 8/2 or x = - 20/2
x = 4 or x = - 10
