for y=ax^2+bx+c
the xvalue of the vertex is -b/2a
and the y value is found by subsituting that for x
so
-b/2a
h(t)=2x^2+4x+7
a=2
b=4
-b/2a=-4/(2*2)=-4/4=-1
the y value
h(-1)=2(-1)^2+4(-1)+7
h(-1)=2(1)-4+7
h(1)=2+3
h(1)=5
(-1,5) is da vertex
Ginny needs cups of sugar to make 36 cookies.
Step-by-step explanation:
Given,
Sugar cups required for 24 cookies =
Ratio of sugar cups to cookies =
Let,
x be the number of cups needed for 36 cookies.
Ratio of sugar cups to cookies =
Using proportion;
Ratio of sugar cups to cookies :: Ratio of sugar cups to cookies
Product of mean = Product of extreme
Dividing both sides by 24
Ginny needs cups of sugar to make 36 cookies.

Craming last minute can lead to unecessary confusion however most examinars dont allow asking questions during exam
So if asking questions for clarification is allowed. A) is the odd one out
