<span> f(x) = x^2 + 4x − 1 and g(x) = 5x − 7
</span>(fg)(x) = (x^2 + 4x − 1)(5x − 7)
(fg)(x) = 5x^3 + 20x^2 - 5x - 7x^2 - 28x + 7
(fg)(x) = 5x^3 + 13x^2 - 33x + 7
answer is C. third choice
(fg)(x) = 5x^3 + 13x^2 - 33x + 7
P=63+63(3/100)
p=63(1+3/100)
p=63(1.03)
p=$64.89
Answer:
Simple interest = PRT/100
300 = 150 x 4 x T/100
2 x 100/4 = T
Therefore T = 50 years
Hope this helps!
