suppose a parabola has an axis of symmetry at x=-2, a maximum height of 8, passes through the point (-6, 2). Wrire the equation of the parabola in vertex form.
Answer:
y = -3/8(x + 2)^2 + 8
Step-by-step explanation:
vertex form is
y = a(x - b)^2 + c where a is a constant and (b,c) is the vertex.
The maximum is at (-2, 8) because x 8 = height and x =-2 is equn. of symmetry
So here we have
y = a(x - (-2))^2 + 8
y = a(x + 2)^2 + 8
Now at the point (-6, 2):
2 = a(-6+2)^2 + 8
2 = 16a + 8
16a = -6
1 = -3/8.
So our equation is y = 3/8(x + 2)^2 + 8
If 3/4 and 12/x are equlvalent, what is the value of x?
Answer:
[tex] \frac{3}{4} = \frac{12}{x} \\ 3x = (12 \times 4) \\ x = \frac{(12 \times 4)}{3} \\ x = (4 \times 4) \\ x = 16[/tex]
Answer:
x = 16
Step-by-step explanation:
so 3/4 = 12/x
you Can multiply 3/4 by 4 to get
12/16 = 12 / x

Please help! The Sugar Sweet Company will choose from two companies to transport its sugar to the market. The first company charges $3495 to rent trucks plus an additional fee of $255.50 for each ton of sugar. The second company charges $5500 to rent trucks plus an additional $125.25 fee for each ton of sugar. For what amount of sugar do the two companies charge the same? What is the cost when the two companies charge the same?
Answer:
The cost when the two companies charge the same is $7,703.
Step-by-step explanation:
Let 'x' represent the number of tons.
For x tons the first company will charge:
5297 + 200.50x
For x tons the second company will charge:
6500 + 100.25x
We want to find x so that both companies charge the same, that is:
5297 + 200.50x = 6500 + 100.25x
x = 12 tons
For 12 tons both companies will charge the same.
The cost charged for 12 tones is:
5297 + 200.50*12 = $7,703
Hope this Helps! :)

The manager of a shopping center wishes to obtain information on the shopping habits of people in the area. The area
contains four neighborhoods of varying populations. The manager suspects that the shopping habits may be different
in different-sized neighborhoods. Which of the following sampling designs would be most effective in gathering the
information the manager requires?
a convenience sample from the area
O a simple random sample from the area
O a cluster sample using the neighborhoods as clusters
O a stratified sample from the neighborhoods in the area
O an online poll that invites all people from the neighborhoods in the area to participate
Answer:
Option C wil be most effective in gathering the information that the manager requires.
Step-by-step explanation:
Internal and external environment influnces any kind of business. we should have proper knowledge of internal and external factors which affects our business.In given case, Taste and preference affects the demand and supply of consumer and shopping center.

For each table, determine whether it shows that X and Y are proportional. If X and y are proportional, fill in the blank with a number in simplest form. I REALLY NEED HELP WITH THIS! Please give a detailed explanation! Will mark brainliest if you have a detailed explanation! Note: it can be a fraction.
Step-by-step explanation:
For table 1,
x = 20 36 56 80
y = 4 6 8 10
Taking 20/4 = 5
36/6 = 6
56/8 = 7
80/10 = 8
The value of x/y is not same in any of the cases. The constant of proportionality is different. It means x and y for this table is not proportional.
For table 2,
x = 28 42 56 70
y = 20 30 40 50
Taking 28/20 = 1.4
42/30 = 1.4
56/40 = 1.4
70/50 = 1.4
The value of x/y is same in each case. The constant of proportionality is same i.e. 1.4 in each case.
[tex]\dfrac{x}{y}=1.4\\\\\dfrac{y}{x}=\dfrac{1}{1.4}\\\\\dfrac{y}{x}=\dfrac{5}{7}\\\\y=\dfrac{5}{7}\times x[/tex]
So, y is 5/7 times of the x.

Step-by-step explanation:
From left to right you are changing the x value and from up to down you are changing the y value. In this case, you are adding 3 units from -3 in which your x-coordinate is 0 and also adding 4 units from -2 in which your y-coordinate is 2.
Juanita ran 8.3 miles in Week 1 and 12.09 miles in Week 2. She used the subtraction below to determine how much farther she ran in Week 2 than in Week 1.
12.09 minus 8.30 = 4.79. All decimals are aligned. The 0 in 12.09 is crossed out and a 1 is above it. The 2 is crossed out in 12.09 and a 1 is above it.
Which error did Juanita make?
She subtracted instead of added.
She aligned the decimal points incorrectly.
She did not regroup correctly when subtracting.
She made a computational error when subtracting.
Step-by-step explanation:
12.09 - 8.30 = 3.79
The reason why her answer was wrong is because when the '2' gets slashed into a '1' during carry over, it would have been 11 - 8 = 3 instead of a 4. (the 1st column)
The error that Juanita made is that she made a computational error when subtracting.

Ellie bought 5 chicken wings for $10.00. If Ellie spent $16.00, how many chicken
wings did she buy?
Answer:
In all, she bought 8, or three more.
Step-by-step explanation:
If 5 chicken wings are for ten dollars, that means each wing is 2 dollars.
If each wing is two dollars then you divide the sixteen dollars by 2 dollars getting 8 wings.
Answer:
Ellie can buy 8 chicken wings
Step-by-step explanation:
From what we know, Ellie was able to by 5 chicken wings for $10, when dividing 10 by 5 we now know that each chicken wing could've cost her $2. So in order to find out how many chicken wings she can buy we can divide 16 by 2 and get 8. Hope this helps! :)
A rhombus, which is a quadrilateral with 4 equal sides, is plotted on the coordinate plane. The coordinates of the vertices are: (−1,0), (4,0), (2,4), and (7,4). How long is each side of the rhombus?
Answer:
Each side of the Rhombus is 5 units
Step-by-step explanation:
Since the sides of a rhombus area all equal in length;
Then, the length of a side is enough to get the lengths of the other sides
Mathematically, finding the distance between two points out of what we are given will be enough to get the measure of one of the side of the rhombus
We apply the distance formula appropriately to get the distance between the side of the Rhombus
D = √(x2-x1)^2 + (y2-y1)^2
let us use the points (-1,0) and (4,0)

Perimeter of a rectangular concrete slab is 102 feet and it's area is 560 ft.² what is the length of the longer side of the slab
Answer:
The longer length is 35ft
Step-by-step explanation:
Given
[tex]Area = 560[/tex]
[tex]Perimeter = 102[/tex]
Required
Determine the longer length
Represent the length with L and width with W
So, we have:
[tex]L * W = 560[/tex] --- Area
[tex]2*(L+W) = 102[/tex] --- Perimeter
Divide both sides by 2 in:
[tex]2*(L+W) = 102[/tex]
[tex]L + W = 51[/tex]
Make L the subject:
[tex]L = 51 - W[/tex]
Substitute 51 - W for L in [tex]L * W = 560[/tex]
[tex](51 - W) * W = 560[/tex]
[tex]51W - W^2 = 560[/tex]
Reorder the equation
[tex]W^2 - 51W + 560 = 0[/tex]
Expand
[tex]W^2 -35W - 16W + 560 = 0[/tex]
[tex]W(W-35)-16(W-35) = 0[/tex]
[tex](W-16)(W-35) = 0[/tex]
Split:
[tex]W - 16 = 0\ \ \ W - 35 = 0[/tex]
[tex]W = 16\ \ \ W = 35[/tex]
This implies that the longer length is 35ft

The sum of 2 consecutive odd integers is -60.
What are the integers?
I need help!
=======================================================
Explanation:
Consecutive integers are integers that follow one right after another. For example, the set {3,4,5} represents consecutive integers.
Consecutive odd integers are a similar idea but that every value is odd. Example: {7,9,11,13}
Let x be some integer. If we multiply it by 2, then it's always even. So 2x is always even. Adding 1 to it makes it odd. So 2x+1 is odd.
The next odd integer after (2x+1) is (2x+3)
Add those two integers and set that sum equal to -60. Solve for x.
(2x+1)+(2x+3) = -60
4x+4 = -60
4x = -60-4
4x = -64
x = -64/4
x = -16
If x = -16, then
2x+1 = 2*(-16)+1 = -32+1 = -31
2x+3 = 2*(-16)+3 = -32+3 = -29
Then note how -31+(-29) = -60 which confirms our answers.
