The vertex form of the quadratic equation given is y = 4(2x +1)² -12
<h3>What is an Equation ?</h3>
An equation is formed when two algebraic expressions are equated by an equal sign , It has wide usage in mathematics to find the unknown variables.
A quadratic equation is given
y = 4x² +16x -48
The vertex form has to be written for it
The standard quadratic equation is
y = a(x-h)² +k
where h and k are the vertex
From the given equation
y = 4x² +16x +4 - 4 -8
y = (4x+2)² -12
y = 4(2x +1)² -12
So here it is in the standard form
Vertex is (-1 , -12)

Answer:
5 4/9
Step-by-step explanation:
9 * 5 = 45
49 - 45 = 4
Answer:
Transitive property
But it looks like substitution.
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
3/4 + 6/10
Find a common denominator and find what you multiply to each denominator to get that number and multiply the numerator by the same amount
(3/4 * 5/5) + (6/10 * 2/2)=
15/20 + 12/20
Then add
15/20 + 12/20= 27/20
Then finally convert to mixed number
27/20 = 1 7/20
To compare the two classes, the Coefficient of Variation (COV) can be used. The formula for COV is this:
C = s / x
where s is the standard deviation and x is the mean
For the first class:
C1 = 10.2 / 75.5
C1 = 0.1351 (13.51%)
For the second class:
C2 = 22.5 / 75.5
C2 = 0.2980 (29.80%)
The COV is a test of homogeneity. Looking at the values, the first class has more students having a grade closer to the average than the second class.
