(f o g)(x) = f(g(x)) so we plug in the equation for g(x) where the x-variable is in f(x).
5(x + 1)³
5[(x + 1)(x + 1)(x + 1)]
5[(x² + 2x + 1)(x + 1)]
5(x³ + 3x² + 3x + 1)
(f o g)(x) = 5x³ + 15x² + 15x + 5
Answer:
C) about 113
Step-by-step explanation:
"How many people are there per square mile?" means that we want a ratio with miles as denominator. In other words, to find the population density, we just need to divide the population by the land area (miles squared):

We know that the population of Alabama is 90,000 people and its land area is 800 miles squared, so
and
.
Replacing values:



Which rounds to:

We can conclude that there are approximately 113 people per square mile in Alabama.
Answer:
Solution,
CP of a bicycle=$3000
Marked up=40%
Now,
→40% of $3000
→40/100x$3000
→$1200
→$3000+$1200=$4200
Again,
Discount(d)=30%
→30%of $4200
→30/100x$4200
→$1260
Hence, the discount price of the bicycle is $1260
Step-by-step explanation:
Answer:
4g/cm^3
Step-by-step explanation:
Solution,
Given:
Mass=12g
Volume=3cm^3
Density=?
we know that,
I) Density=Mass/volume
=12g/3cm^3
=4g/cm^3
Therefore, required answer of above question is 4g/cm^3.
