There are 8 people who do not like reading, and 2 people who do not enjoy playing video games. There is one person who does not like reading or playing video games.
This makes 9 non readers and 3 non gamers.
Ratio is 9:3 which simplifies to 3:1
X=-b/2a is the formula for finding the axis of symmetry
So x= -30/2(5)
X=-30/10
X=-3
Because the axis of symmetry is -3, we know where to place our line, and we also know that the parabola is open downwards, which means that the vertex will be maximum. To find the vertex, plug in your values with the axis of symmetry as a midway point. Plug that in for x and so you should have the following:
F(x)
Y(f(x) and y variables are interchangeable) =5(-3)^2-30(-3)+49
Solve for y(f(x))
5(-3)^2-30(-3)+49
(-3)^2=3^2
3^2*5+30*3+49
Multiply
3^2*5+90+49
Add numbers
3^2*5+139
9*5=45
45+139=184
Y=184
So, your vertex would be
(-3,184) and it would be maximum. From there you can plug in the rest of your table of values.
C.416
You take 312 and 6 then divide (312/6) which gives you 52. Then take 52 and 8 and multiply 52×8= 416
