Answer:
(x + 3)(x - 1)(x + 2)
Step-by-step explanation:
The fractions are:
Factor each denominator
We must find the least common multiple of the denominators. We take the maximum power of each separate factor.
Factors of first fraction = (x + 3) × (x - 1)
Factors of second fraction = (x + 3) × (x + 2)
LCM = (x + 3)(x - 1)(x + 2)
The lowest common denominator of the two fractions is (x + 3)(x - 1) (x + 2).
Answer:
Part a) The fraction is
Part b) The percent is
Step-by-step explanation:
Part a)
Find the fraction
we know that
To find the fraction of the shaded part in the square divide the number of shaded squares by the total number of squares
so
Let
x-------> the number of shaded squares
y-------> the total number of squares
f-------> the fraction of the shaded part
so
In this problem we have
substitutes
Simplify
Part b) Find the percent
To find the percent multiply the fraction by 100
so
convert to mixed number
Answer:
Step-by-step explanation:
As you can see from the graph I attached you, the possible solutions in the interval from 0 to 2π are approximately:
So, it's useful to solve the equation too, in order to verify the result:
Taking the inverse sine of both sides:
Using this result we can conclude the solutions in the interval from 0 to 2π are approximately:
