Answer:
(4, -25)
Step-by-step explanation:
In this case, the quadratic formula is in the form:
ax² + bx + c
Since they also give you the formula for the vertex, you just need to plug the values in.
The x coordinate in the vertex is 8/2(1), or 4.
You take the x = 4 and plug it into your quadratic equation.
f(4) = 16 - 32 -9
= -25
The vertex is (4, f(4)) or (4, -25)

28
So 1% of 350 would be 3.5 because 350 divided by 100 is 3.5. You then get 3.5 and multiply it 8 times, which would be 28. (You multiply it 8 times because 8% is 8 times 1%.)
2
8/4 = 2
=
Therefore: 2
