Answer:
the interest earned= 93.401
and the future value of an annuity= 493.401
Step-by-step explanation:
Given Data:
Interest rate= 7%
time,t = 3 years
weekly payment, P= 400
At the end of 3 years, final investment A= ?
n= 52 as it is weekly
As per the interest formula
A= P(1+r/n)^nt
Putting value in above equation
= 
= 493.401
Interest earned = A-P
= 493.401-400
= 93.401 !
Answer:
(12x²+4)(x-5)
Step-by-step explanation:
To factor the expression factor by grouping.
(12x³ - 60x²) + (4x - 20)
12x²(x - 5) 4(x-5)
(12x²+4)(x-5)
