Hey there! :)
Answer:
A. [tex]f(x) = (x - 2)^{4}[/tex]
Step-by-step explanation:
Recall that the transformation form of a polynomial with degree four is:
[tex]f(x) =[/tex] ±[tex]a(b(x-h))^{4} +k[/tex]
In this instance, we will need to use the h value, or the horizontal shift.
It is given that there is only a horizontal shift of 2 units to the right, or h = 2. Plug this into the equation:
[tex]f(x) = (x - 2)^{4}[/tex]
Below is the work a student completed with an error. Identify the step where the error occurred and give the correct solution. Step 1:(12-20)-3(8-3)+13 Step 2:-8-24-9+13 Step 3:-32-9+13 Step 4:-41+13
Answer:
The error is in Step 2. The student distributed -3 incorrectly; it should have been 9, not -9. The correct solution is -8 - 24 + 9 + 13 = -32 + 9 + 13 = -32 + 22 = -10.
I NEED HELP ASAP PLEASE, A woodworker makes wooden checkerboards. Her profit is a function of the price
she charges. This graph shows her total profits, y, based on the sales price, x, of
each checkerboard.
Identify any zeros of the function, and interpret what the zeros mean in terms of
the situation.
A. Zero: x = 42.5. This is the selling price that will give her the greatest
profit.
B. Zeros: x = 20 and x = 65. These are the prices at which she makes the
least and greatest amounts of profit.
C. Zeros: x = 20 and x = 65. These are the prices at which she neither
makes nor loses money.
D. Zero: y = 1012.5. This is the maximum amount of profit she can make.
Answer:
Option (C)
Step-by-step explanation:
The given graph represents the relation between her profit and the price charged.
x-intercepts from the graph are at,
x = 20 and x = 65, which show the selling prices.
x-intercepts means y = 0
And y = 0 represents no profit no loss.
When we summarize these data,
zeros : x = 20 and x = 65
These are the selling prices that will give her neither profit nor loss.
Therefore, Option (C) will be the answer.

Step-by-step explanation:
Trapezoid ABCD is rotated 180 degrees about the origin and then reflected over the x-axis, followed by a reflection over the y-axis. What is the location of point A after the transformations are complete?
Answer:
the location of point A after the transformations are complete is (-5, 1)
Step-by-step explanation:
Given the coordinate of the trapezoid at A(-5, 1), B(-4, 3), C(-1, 3) and D(-2, 1).
The location of point A is at (-5, 1) which is the second quadrant, when it is rotated 180 degrees about the origin, the point moves to the fourth quadrant and the new point is at (5, -1). If it is then reflected over the x axis, the x coordinate remain the same and the sign of the y coordinate changes making the new point (5, 1). If it is then reflected over the y axis, the y coordinate remain the same and the sign of the x coordinate changes making the new point (-5, 1).
the location of point A after the transformations are complete is (-5, 1)
Answer:
the location of point A after the transformations are complete is (-5, 1)

A coal car on a train weighs 30 tons plus 1 ton per cubic yard of coal x that it carries. The total weight of a coal car is: f(x) = x + 30. How will the graph of this function change if the coal car weight is changed to 26 tons?
Answer:
See explanations below
Step-by-step explanation:
In the function
f(x) = x + 30
x represents the volume of coal in cubic yards.
The implicit coefficient of one, i.e. 1x, represents each cubic yard of coal weighs one ton.
The 30 represents the weight in tons of the empty coal car.
Thus when the weight of the coal car is only 26 tons, we replace 30 by 26 to get a new function
f(x) = x + 26.

If Q and T are midpoints, then the triangles URS and UQT are similar triangles and verify the following proportions:
[tex]\frac{QT}{RS} =\frac{UQ}{UR} =\frac{UT}{US} =\frac{1}{2}[/tex]
and all should equal 1/2 because Q and T are midpoints.
Then we study in particular the proportion:

since we know both segments can be expressed in terms of "p" as indicated in the problem:
[tex]\frac{QT}{RS} =\frac{1}{2}\\\frac{p-87}{p-74} =\frac{1}{2}\\2(p-87)=p-74\\2p-174=p-74\\2p-p=174-74\\p=100[/tex]
what is this answer 4\5+2\10
Answer:
1
Step-by-step explanation:
To add fractions, we need to make the denominators the same. Luckily, we can simplify 2/10 to 1/5. Now that the denominators are both 5, we can add. When adding fractions, we only add the numerator, and the denominator remains the same, so we'd do 4+1/5, which equals 5/5, which simplifies to 1.
Answer:
1 or 10/10
Step-by-step explanation:
Step 1 make a common denominator
to make a common demoniator multiply the top and bottom number by the same number
so multiply the 4 and 5 by 2 to get 8/10
Step 2 now that you have 8/10 add it with 2/10
Step 3 solve to get 10/10 and then simplify it to 1
What is the slope of the line with equation y−3=-1/2(x−2)?
Answer:
m = -1/2
Step-by-step explanation:
y= m+b
y = -3 = -1/2 (x-2)
y = -1/2(x-2)+3
y = -1/2x-2x(-1/2)+3
y = -1/2+1+3
y = -1/2+4
Hence, the slope is -1/2

Complete Question:
Madison claims that two data sets with the same median will have the same variability. Which data set would provide good support for whether her claim is true or false?
A. Her claim is true and she should use these data sets to provide support. A box-and-whisker plot. The number line goes from 0 to 11. The whiskers range from 2 to 11, and the box ranges from 4 to 9. A line divides the box at 7. A box-and-whisker plot. The number line goes from 0 to 11. The whiskers range from 2 to 11, and the box ranges from 4 to 9. A line divides the box at 6.
B. Her claim is true and she should use these data sets to provide support. A box-and-whisker plot. The number line goes from 0 to 11. The whiskers range from 2 to 11, and the box ranges from 4 to 9. A line divides the box at 7. A box-and-whisker plot. The number line goes from 0 to 11. The whiskers range from 2 to 11, and the box ranges from 5 to 8. A line divides the box at 7.
C. Her claim is false and she should use these to show that two data sets with the same median can have different variability. A box-and-whisker plot. The number line goes from 0 to 11. The whiskers range from 2 to 11, and the box ranges from 4 to 9. A line divides the box at 7. A box-and-whisker-plot. The number line goes from 0 to 11. The whiskers range from 2 to 11, and the box ranges from 5 to 8. a line divides the box at 7.
D. Her claim is false and she should use these to show that two data sets with the same median can have different variability. A box-and-whisker plot. The number line goes from 0 to 11. The whiskers range from 2 to 11, and the box ranges from 4 to 9. A line divides the box at 7. A box-and-whisker-plot. The number line goes from 0 to 11. The whiskers range from 2 to 11, and the box ranges from 5 to 8. a line divides the box at 5.5.
Answer:
C. Her claim is false and she should use these to show that two data sets with the same median can have different variability. A box-and-whisker plot. The number line goes from 0 to 11. The whiskers range from 2 to 11, and the box ranges from 4 to 9. A line divides the box at 7. A box-and-whisker-plot. The number line goes from 0 to 11. The whiskers range from 2 to 11, and the box ranges from 5 to 8. a line divides the box at 7.
Step-by-step explanation:
The median of a box plot is indicated by the line that divides the rectangular box into 2.
Also, the interquartile range is a measure of variability. And this is indicated or represented on a box plot by the range of the box. That is the difference between one end of the box and the beginning of the other end to our left.
The data set that can be used to show that Madison claim is false is a data set showing 2 box plots with the same median value but different interquartile range.
Therefore, C is the right option. Both data set in the drop box would have a median of 7. The interquartile range of one of the drop box would be = 9-4 = 5, while the other would be = 8-5 = 3.
This shows 2 data set with the same median can have different variability.

REcall that sin(a+b) = sin(a)cos(b)+cos(a)sin(b). Then
sin(a+b)+sin(a-b) = sin(a)cos(b)+cos(a)sin(b) + sin(a)cos(b) -cos(a)sin(b) = 2sin(a)cos(b). Then
sin(a)cos(b) = (1/2)(sin(a+b)+sin(a-b))

An interior angle of a regular convex polygon is 135°. How many sides does the polygon have?
Hey there! :)
Answer:
The polygon has 8 sides.
Step-by-step explanation:
Use the sum of interior angles formula to solve.
The sum of the interior angles is equal to (n-2)180. If 135° is one angle, we can simply set up an expression to represent this situation:
135 = (n-2)· 180 / n
Multiply both sides by n:
135n = (n-2) · 180
Distribute the 180:
135n = 180n - 360
Subtract 180n from both sides:
-45n = -360
Divide both sides by -45:
n = 8. The polygon has 8 sides.
Answer:8 sides

Answer:
I think the answer is B. Let me know if im right
Step-by-step explanation:
l*w*1/2 is the same as 1/2*y*(x2-x1)
Answer:
B
Step-by-step explanation:
To calculate the area of this triangle we must use vectors :
vector1 (x1-0,y1-0)⇒ vector1(x1,y1)vector2 (x2-0,y1-0)⇒vector(x2,y1)Now to calculte the area of this triangle we must apply this relation :
A= (1/2)*║x1y1-x2y2║
x2≥x1 so ⇒ A=(1/2)*(x2y1-x1y1)A= (1/2)*y1*(x2-x1)The equation yˆ=−6.2x2+41.5x−5.6 approximates the average number of cars that pass through an intersection x hours after 3:00 p.m. What is the best estimate for the average number of cars that pass through the intersection at 5:30 p.m.?
Answer:
59
Step-by-step explanation:
5: 30 pm is 2.5 hours after 3 : 00 pm
Substitute x = 2.5 into the equation
y = - 6.2(2.5)² + 41.5(2.5) - 5.6
= - 38.75 + 103.75 - 5.6
= 59.4
The average number of cars is 59
