6 0

Answer:

(D). 6.

Step-by-step explanation:

The number of parts = 1 + 10 = 11.

Given f(x) = 2x^2 -3x and g(x) = x+4
Alenkasestr [34]

Answer:

2x³ + 5x² - 12x

Step-by-step explanation:

The correct answer doesn't seem to be listed...

(fg)(x) = (2x² - 3x)(x + 4)

Which equals...

2x²(x) + 2x²(4) + (-3x)(x) + (-3x)(4)

Which simplifies to...

2x³ + 8x² - 3x² - 12x

     2x³ + 5x² - 12x

Answer:

  • 2^45 or ≈ 3.5*10^13

Step-by-step explanation:

<u>Given equation</u>

  • f(t) = 2^(kt)
  • f - number of cells, t - number of months, k- coefficient

<u>We got 32 cells in the first month. It means:</u>

  • t = 1, f(1) = 32

<u>Using these numbers we can find the coefficient k:</u>

  • 32 = 2^(k*1)
  • 2^5 = 2^k
  • k = 5

<u>Then the equation becomes:</u>

  • f(t) = 2^(5t)

<u>Average time is 9 months, we can calculate the number of cells:</u>

  • f(9) = 2^(5*9) = 2^45 ≈ 3.5*10^13
