So, c(x) = 4x - 2, d(x) = x^2 + 5x.
c(x)*d(x) = (4x - 2)(x^2 + 5x)
= (4x^3 + 20x^2 - 2x^2 - 10x)
= (4x^3 + 18x^2 - 10x)

A biologist is researching a newly-discovered species of bacteria. He puts 1,000 bacteria into what he has determined to be a fa
Svetradugi [14.3K]
The bacteria grow from <span>1,000 bacteria into 12,500 bacteria in 12 hours.  The exponent function would be:

an= ao(1+r)^t
12.500= 1,000(1+r)^12
1,000(12.5)= 1,000(1+r)^12
</span>12.5= (1+r)^12
1+r= 1.23427
r= 0.23

Number of bacteria after 20hr would be:
an= ao(1+r)^t
an= 1,000(1+0.23)^20
an= 1,000(62.821 <span>)
an= </span><span>62,821 </span>
