So the common ratio is 1/2 which means the equation is

\Large y = 400(1/2)^{x-1}

which is in the geometric sequence format. So the answer is choice D

Bogdan [553]
The answer is m(n)= 11n
If you take the different of the money from 21 cars and 25 cars, you get 44 and since 21 and 25 is only a difference of 4, you’ll divide the 44 earned by the 4 cars washed to get $11 per car and then just make sure to use the correct variables

If c(x) = 4x – 2 and d(x) = x2 + 5x, what is (cd)(x)?
ludmilkaskok [199]

Answer: cd(x) = 4x³ — 2x² + 8x — 4

Step-by-step explanation:

c(x) = 4x - 2

d(x) = x² + 2

Therefore, cd(x) = c(x) × d(x)

cd(x) = (4x - 2)(x² + 2)

= (4x × x²) + (4x × 2) + (-2 × x²) + (-2 × 2)

= 4x³ + 8x -2x² - 4

cd(x) = 4x³ — 2x² + 8x — 4

Hope this helps?
