To do this, we first want to see how many participants there are in total by adding both males and females.
Now we know that there were 220 total participants, but only 121 were females.
This allows us to set up the fraction 121/220= the percent female.
or 55%
first off, let's notice the parabola is a vertical one, therefore the squared variable is the x, and the parabola is opening upwards, meaning the coefficient of x² is positive.
let's notice the vertex, or U-turn, is at (-2, 2)
The results of the composite functions are:
<h3>What are composite functions?</h3>
Composite functions are functions that are obtained by combining two or more functions together
Assume that:
Then the computation of the composite functions are as follows:
<h3>Function (f * g)(x)</h3>
<h3>Function f(g(x))</h3>
We have:
This gives
So, we have:
<h3>Function g(f(x))</h3>
We have:
This gives
So, we have:

Answer
a first one is 52 (90-38=52)
Second one is 32 (180-148=32
I can’t see the third or 4th one
