Step-by-step explanation:
Parabolas can be written in the form
[tex]y = a(x-h)^2+k[/tex]
The vertex is (h, k). The vertex in the graph is (5, 0).
so far, we have
[tex]y = a(x-5)^2+0\\y = a(x-5)^2[/tex]
The other points we are given are (6, 1), (7, 4), (8, 9)
[tex]9 = a(8-5)^2\\9 = a(3)^2\\9 = 9a\\a = 1\\\\4 = a(7-5)^2\\4 = a(2)^2\\4 = 4a\\a = 1\\\\1 = a(6-5)^2\\a = 1[/tex]
In vertex form
[tex]y = (x-5)^2\\y = x^2 - 10x + 25[/tex]

The wholesale price of a jacket is $72. If the jacket is sold in a department store for a retail price of $86.40, what is the percent markup?
Answer:
20%
Step-by-step explanation:
Subtract the selling price from the wholesale price.
86.40-72.00=14.4
Find the percentage of the difference from the wholesale price.
14.4/72.0=0.2
This means 20%.

An office receives a shipment of identical boxes containing office supplies. The shipment contains 6 boxes of pencils, 14 boxes of pens, and 16 boxes of paper. How many additional boxes of paper must be added to the original 36 boxes in order for the probability of randomly selecting a box of paper from this shipment to be exactly 1/2 ?
Answer:
4
Step-by-step explanation:
Given that:
There are 6 boxes of pencils, 14 boxes of pens and 16 boxes of paper.
Total number of original boxes = 6 + 14 + 16 = 36
To find:
Number of additional boxes of paper to be added so that the probability of getting a paper box while selecting a random box becomes exactly [tex]\frac{1}{2}[/tex].
Solution:
First of all, let us have a look at the formula of probability:
Formula for probability of an event E can be observed as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
Here, number of favorable cases will be equal to the number of paper boxes and
Total number of cases will be equal to the total number of boxes available.
Let us first calculate the original probability:
[tex]\frac{16}{36}\neq \frac{1}2[/tex]
If 1 paper box is added, then probability
[tex]\frac{17}{37}\neq \frac{1}2[/tex]
If 2 paper boxes are added, then probability
[tex]\frac{18}{38}\neq \frac{1}2[/tex]
If 3 paper boxes is added, then probability
[tex]\frac{19}{39} \neq \frac{1}2[/tex]
If 4 paper boxes is added, then probability
[tex]\frac{20}{40} = \frac{1}2[/tex]
Therefore, we need to add 4 paper boxes.
The probability of randomly selecting a box of paper from this shipment to be exactly 1/2 need to add 4 boxes.
Given that,
The shipment contains 6 boxes of pencils
And 14 boxes of pens, and 16 boxes of paper.
We have to find,
How many additional boxes of paper must be added to the original 36 boxes in order for the probability of randomly selecting a box of paper from this shipment to be exactly 1/2.
According to the question,
Total no. of original boxes = 6 + 14 + 16 = 36
Formula for probability of an event E can be observed as:
[tex]P(E) = \frac{Number \ of \ favourable \ cases}{Total \ number \ of \ cases }[/tex]
Here, number of favorable cases will be equal to the number of paper boxes,
Total number of cases will be equal to the total number of boxes available.
The probability of randomly selecting a box of paper from this shipment to be exactly 1/2 .
Let us first calculate the original probability:
[tex]\frac{16}{36} \neq \frac{1}{2}[/tex]
The probability of original paper boxes is not 1\2.
If 1 paper box is added, then probability,
[tex]\frac{17}{37} \neq \frac{1}{2}[/tex]
The probability of 1 paper boxes is not 1\2.
If 2 paper box is added, then probability,
[tex]\frac{18}{38} \neq \frac{1}{2}[/tex]
The probability of 2 paper boxes is not 1\2.
If 3 paper boxes are added, then probability,
[tex]\frac{19}{39} \neq \frac{1}{2}[/tex]
The probability of 3 paper boxes is not 1\2.
If 4 paper boxes is added, then probability,
[tex]\frac{20}{40} = \frac{1}{2}[/tex]
The probability of 4 paper boxes is 1\2.
Hence, The probability of randomly selecting a box of paper from this shipment to be exactly 1/2 need to add 4 boxes.

Step-by-step explanation:
alberto knows that all the lines and rays are congruent to each other . he reasons that all segments must therefore be congruent to each other. alberto conclude that AB CD What is his error
Answer:
Step-by-step explanation:
Alberto is correct in reasoning that all lines and rays are congruent to each other but incorrect in his reasoning about the line segments.
Line segments are equal in measure only when they are equal in length. They can have any orientation on a plane.
Since, AB = 3 units
CD = 4 units
Therefore, AB ≠ CD
Error in AB ≅ CD

write an equation for a line through (1,-1) and (2,3)
Answer:
y = 4x - 5
Step-by-step explanation:
Use the point slope form and add in the ordered pairs [tex]\frac{3 + 1}{2 - 1}[/tex] , and once you solve this it equals [tex]\frac{4}{1}[/tex], or just 4. Now you have the first part of your equation, y = mx + b, but now you have y = 4x + b. To find b, substitute the x and y values of one of the given ordered pairs in for x and y in the equation, and I am using (2,3). The equation now looks like this: 3 = 4(2) + b. Now solve: 3 = 8 + b
Subtract 8 from both sides to get -5 = b. Now you have a full equation: y = 4x -5
a 12 inch candle burns down in 12 hours. at what rate does the candle burns, in inches per hour?
Answer:
1 inch per hour because it took 12 hours to burn a 12 inch candle so 1 inch per hour
The candle burns at a rate of 1 inch per hour.
What is a unitary method?
A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, A 12-inch candle burns down in 12 hours.
∴ The rate at which it burns per hour is the total length of the candle divided by the total time it brunt for which is,
= (12/12) inch/hr.
= 1 inch/hr,

Two rectangular prisms are similar. The ratio of the areas of the bases is 121:49. What is the ratio of the volumes of the similar solids?
Answer:
The ratio of the volumes of the similar solids is 1331:343.
Step-by-step explanation:
Ratios
Given the ratio of two lengths is a:b. Given a two-dimensional shape is similar to another shape, the ratio of their areas is [tex](a/b)^2[/tex], and the ratio of their volumes is [tex](a/b)^3[/tex].
We know the ratio of the areas of the bases of two similar rectangular prisms is 121:49. Thus, the ratio of its dimensions is:
[tex](a/b)^2=(121/49)[/tex]
Taking the square root:
[tex]a/b = \sqrt{121/49}=11/7[/tex]
Thus, the ratio of the volumes is:
[tex](a/b)^3=(11/7)^3=1331/343[/tex]
The ratio of the volumes of the similar solids is 1331:343.

Answer:
88
Step-by-step explanation:
m<ACB is equal to m<ABC because when to split the triangle down the middle and reflect one half you would have the same open shape. So by knowing that, you add 46+46 to get 92. Also knowing a triangle is equal to 180, you would end up subtracting 92 from 180 to get 88.

y=-x
slope for perp line = 1
2y=-x+6
y=-1/2x +3
slope for perp line = 2
15.
i don’t wanna do all sorry it’s a lot of work so i’ll tell u how to do it instead. first write it in slope intercept form which is
y-y1=m(x-x1)
it’s parallel which means it shares the same slope. if it’s perpendicular it would be opposite reciprocals so for -3/2 the perp slope would be 2/3.
the line is
y+1=3/4(x-4)
we distribute the 3/4 so it’s now
y+1=3/4x-3
then we subtract the 1
y=3/4x-4 is the equation boom done
