Multiply (1/2) (-1/4) Which of the following is correct?

Answer:
Hey there! your answer should be the first choice, -1/8
Step-by-step explanation:
multiplication and division in fraction are way easier than adding and subtracting them since you don't have to use factoring much.
so first you set them aside
then, literally just multiply them across.
meaning, top times top a.k.a. the numerator and bottom times bottom a.k.a. the denominator
check this little cheat code
positive x positive = positive
negative x negative = positive
positive x negative = negative
negative x positive = negative
so lets do the top, the numerators first: 1 x (-1) = -1
then the bottom, the denominators next: 2 x 4 = 8
now replace your answer with that and you get which leads you with the first answer choice.
I hope this helps! :)

Given:
The function is:
To find:
Express the quadratic equation in the form of , then state the minimum or maximum value,axis of symmetry and minimum or maximum point.
Solution:
The vertex form of a quadratic function is:
...(i)
Where, a is a constant, (h,k) is the vertex and x=h is the axis of symmetry.
We have,
It can be written as:
Adding and subtracting square of half of coefficient of x inside the parenthesis, we get
...(ii)
On comparing (i) and (ii), we get
Here, a is negative, the given function represents a downward parabola and its vertex is the point of maxima.
Maximum value = 10.125
Axis of symmetry :
Maximum point = (1.75,10.125)
Therefore, the vertex form of the given function is , the maximum value is 10.125, the axis of symmetry is
and the maximum point is (1.75,10.125).
