Answer:
Therefore,
....Standard form.
......Numerical Coefficients.
Step-by-step explanation:
Given:
To Find:
a ,b , c
Solution:
Quadratic:
A quadratic equation is an equation of the second degree.
Meaning it contains at least one term that is squared.
The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable.
Here it is given as
Adding 6 on both the side we get
Which is Quadratic Equation in STANDARD form Where,
Therefore,
....Standard form.
......Numerical Coefficients.
C 1.5 , I am almost positive.
Answer:
C is correct.
Step-by-step explanation:
At a picnic,
Number of adults is 3 times as number of children.
Number of women is twice as number of men.
Total number of men, women and children at the picnic be x
Let number of children be c
Let number of men be m
Let number of women be w
# Number of women is twice as number of men, w = 2m
# Number of adults is 3 times as number of children, w + m = 3c
2m + m = 3c (∴ w=2m )
c = m
Total number of men, women and children at the picnic be x
∵ c + m + w = x
m + m + 2m = x
4m = x
Number of men, 
Hence, The total number of men will be
Answer:
no his prediction is not correct. there would be 90 window panes
Step-by-step explanation:
12 panes in 2 windows so 1 window has 6 panes. multiply the 15 windows by 6 panes to get the total of 90 panes
12/2=6
6x15=90
Answer:
Step-by-step explanation:
Answer:
(x-1)²+(y-3.5)² = 265/4
Step-by-step explanation:
first find the midpoint (center of the circle)
(9+-7)/2, (2+5)/2
(1, 3.5) = center
then distance formula to find diameter
√(9- -7)²+(2-5)²=√256+9 = √265
The radius is half the diameter = (√265)/2
Formula for circle is (x-h)²+(y-k)²=r², where (h, k) is the center
Now you can plug everything in.
(x-1)²+(y-3.5)² = 265/4
