Answer:
(f•g)(x) = 5x^3 + 15x^2 + 15x + 5
Step-by-step explanation:
If f(x) = 5x^3 and g(x)= x+1 find (f•g)(x)
(f•g)(x) = (f(g(x))
So
(f(g(x)) = 5(x+1)^3
= 5(x+1)(x+1)^2
= (5x + 5)(x^2 + 2x + 1)
= 5x^3 + 10x^2 + 5x + 5x^2 + 10x + 5
= 5x^3 + 15x^2 + 15x + 5
So
(f•g)(x) = 5x^3 + 15x^2 + 15x + 5
Improper 7/4 and mixed number 1 3/4
So for 4 cans of beans for $9, each can would be $2.25 so then we multiply that by 7 so it would be $15.75 for 7 cans of beans
Answer:
50
Step-by-step explanation:
We know that Lucy can type 52 more words than Jim (who types 548 words in 12 minutes).
Now that we know Lucy can type 600 words in 12 minutes, how many does she type per minute? To solve, we simply divide 600 by 12.
Lucy can types 50 words per minute.
