The equation of the quadratic function f whose graph is shown below is x² + 6.1x + 8.2
Find the diagram attached.
First, we need to get the zeros of the required function. The point where the curve cuts the x-axis is the zeros.
According to the graph, the curve cuts the x-axis at x = -2 and x = -4.1
The required factors will be (x+2) and (x+4.1)
Taking the product of the factors
f(x) = (x+2)(x+4.1)
f(x) = x²+4.1x+2x +8.2
f(x) = x² + 6.1x + 8.2
Hence the equation of the quadratic function f whose graph is shown below is x² + 6.1x + 8.2

Answer:
A=41
B=20
C=8
D=3
Step-by-step explanation:
You need to first of all fill the intersection (yellow region). This is the number of people who use both.
This means B=20
Region A is those who use F only. So you must subtract the number who use both.
This means that A=61-20=41
Region C is those who use G+ only.
This means C=28-20=8
Now A+B+C+D=72
This implies that:
41+20+8+D=72
69+D=72
D=72-69
D=3
Answer:
3 gallons
Step-by-step explanation:
Let
x ----> the amount of pure acid (100% solution) in gallons
Remember that
we know that
solve for x
therefore
3 gallons of pure acid should be mixed with 3 gallons of a 20% acid solution in order to get a 60% acid solution
I’m confused about that sorry
