Answer:
There were 120 questions on the test.
Step-by-step explanation:
It is given that:
Number of questions answered = 54
Grade percent = 45%
Let,
x be the total number of questions
45% of x = 54
Dividing both sides by 0.45
Therefore,
There were 120 questions on the test.

If my answer is helpful please mark me brainliest!
f(x) = - 2(x - )² -
the equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square
• the coefficient of the x² term must be 1 , factor out - 2
= - 2(x² - x) - 2
• add / subtract (half the coefficient of the x-term )² to x² - x
= - 2(x² + 2(- )x + - ) - 2
= - 2(x - )² + - 2
= - 2(x - )² -
