Therefore, the standard for will be:
Step-by-step explanation:
The equation of a parabola written as vertical axes is given by:
(1)
The vertex of the parabola (h,k) is (2,-5).
The focus (h,k+p) is (2,-4)
Then we can find p knowing that:
h = 2
k = -5
k + p = -4 then p = -4+5 = 1
Putting all these values in equation (1) we will find the equation of the parabola:
(2)
Now, we need to find the standard form of the equation of the parabola.
Let's recall that standard form is:
We just need to work out equation (2) to convert it to the standard form.
Therefore, the standard for will be:

So, we have the percentage she gets which is, 90% and the number of questions she answers correctly, which is 27
To find the number of questions in the exam, make an equation
(90% =
= 0.9)
= 
cross multiply and equate them
90x = 27 x 100
90x = 2700
divide by 90 on either sides to isolate x in order to find the answer
90 and 90 cancels out
x = 30
So your final answer will be, there were 30 questions in the exam paper.
