Which triangle is a reflection of triangle ABC over the X axis?
Answers
The correct answer is: Triangle MNO
A reflection of a triangle over the X-axis involves flipping the triangle about this axis. Each point in triangle ABC (A, B, and C) is reflected to a corresponding point A', B', and C' in the reflected triangle such that their Y-coordinates are negated while the X-coordinates remain the same.
Explanation:To understand the concept of the reflection of a triangle, you need to visualize flipping the triangle over a line, in this case, the X-axis. When a triangle named ABC is reflected over the X-axis, the positions of the points change as follows: A (x, y) becomes A' (x,-y), B (x, y) becomes B' (x, -y), and C (x, y) becomes C' (x, -y). Therefore, the triangle that is a reflection of triangle ABC over the X-axis is triangle A'B'C'.

B. y = 1.560x - 4.105
c. y= -1.560x+ 4.105
d. y = 4.105x – 1 560
Answers
Answer: B. y = 1.560x - 4.105*****
Answer:
Option B.
Step-by-step explanation:
The general equation of best fit line is
[tex]y=mx+b[/tex] .... (1)
where, m is slope and b is y-intercept.
[tex]m=\frac{\sum_{i=1}^nx_iy_i-n\overline{x}\overline{y}}{\sum_{i=1}^nx_i^2-n\overline{x}^2}[/tex]
[tex]b=\overline{y}-b\overline{x}[/tex]
Using the graphing calculator we get
[tex]m=1.56015\approx 1.560[/tex]
[tex]b=-4.10526\approx -4.105[/tex]
Substitute m=1.560 and b=-4.105 in equation (1).
[tex]y=1.560x-4.105[/tex]
The equation of the line of best fit for the following data y = 1.560x - 4.105.

|-2-2| = 4
|-4| = 4
2) proof ( replace h with 6)
|6-2| = 4
|4|=4
Hopes this helps !
Answer:
[tex]h = -2\\h = 6[/tex]
Step-by-step explanation:
The absolute value is a function that transforms any value x into a positive number.
Therefore, for the function [tex]f(x) = |x|[/tex] x> 0 for all real numbers.
Then the equation:
[tex]|h-2| = 4[/tex] has two cases
[tex](h-2) = 4[/tex] if [tex]h > 2[/tex] (i)
[tex]-(h-2) = 4[/tex] if [tex]h < 2[/tex] (ii)
We solve the case (i)
[tex]h = 4 + 2\\h = 6[/tex]
We solve the case (ii)
[tex]-h +2 = 4\\h = 2-4\\h = -2[/tex]
Then the solution is:
[tex]h = -2[/tex] or [tex]h = 6[/tex]
Minerva buys used bicycles, repairs them, and sells them for a profit. She bought a bicycle for $10, repaired it, and sold it for $50. What was the percent increase in the price of the bicycle.
A. 400%
B. 80%
C. 40%
D. 4%
Answers
it is an increase of 400%
Final answer:
The percent increase in Minerva's bicycle price is calculated by subtracting the original price from the new price, dividing by the original price, and then multiplying by 100%. The calculation results in a 400% increase.
Explanation:
The percent increase in the price of the bicycle that Minerva bought and sold is calculated using the formula for percent change, which is (New Price - Original Price) / Original Price times 100%. In this case, the original price is $10 and the new price is $50.
To calculate the percent increase:
($50 - $10) / $10 times 100% = $40 / $10 times 100% = 4 times 100% = 400%.
Therefore, the correct answer is 400%, which is option A.

f(x)⁻¹ = x³ + 2
Step-by-step explanation:
Find the inverse of f(x) = ∛(x - 2).
The first step is to let f(x) = y
y = ∛(x - 2)
Then make x the subject of the formula
y³ = [∛(x - 2)]³
y³ = x - 2
x = y³ + 2
∴ f(x)⁻¹ = y³ + 2
Replacing y with x we have.
f(x)⁻¹ = x³ + 2
Find the area of the unshaded portion of this figure. The figures shown below are a trapezoid and a rhombus. Show your work.
Answers
Answer:A-1/2h(b1+b2)
A-1/2*(10.1)*(30.5+21.4)
A-3296.135 i think
Step-by-step explanation:
To find the area of the unshaded portion of a figure containing a trapezoid and a rhombus, calculate the area of each figure first using their respective formulas. Subtract the area of the overlapping (shaded) region from the total to find the area of the unshaded portion.
Explanation:The problem asks to find the area of the unshaded portion of a figure, which includes a trapezoid and a rhombus. Since we don't have the specific values of the sides and heights of each figure, a general approach would be to calculate the area of each figure first, then subtract the area of the shaded (overlapping) region from it.
The formula for the area of a trapezoid is A = 1/2 (a+b)h, where 'a' and 'b' are the lengths of the parallel sides and 'h' is the height. For the rhombus, the formula is A = 1/2 (d1 * d2), where 'd1' and 'd2' are the diagonals.
Assuming you can measure and determine the shaded region, you would compute its area as well and subtract this from the total of the previous two calculations. This would give you the area of the unshaded portion.

A 1/2 yard of ribbon is needed for a craft project. How much ribbon will remain from a piece that measures 7/8 yard?
Answers
1/2 is the same as 4/8, since 4 is 1/2 of 8. So, you just need to subtract 4/8 from 7/8 to find the remaining ribbon.
7/8 minus 4/8 is 3/8, so there would be 3/8 yards of ribbon remaining.
To find out how much ribbon is left after using 1/2 yard from a piece that is 7/8 yard long, convert 1/2 yard to 4/8 and subtract from 7/8, leaving you with 3/8 yard of ribbon remaining.
To determine how much ribbon will remain after using 1/2 yard for a craft project from a piece that measures 7/8 yard, you need to subtract the amount used from the total length you have. Since we are working in yards, ensure both amounts are in the same units. Here are the steps to find the remaining ribbon:
Start with the total length of ribbon: 7/8 yard.
Subtract the length of ribbon used for the project: 1/2 yard.
Convert 1/2 yard to an equivalent fraction with a denominator of 8, which is 4/8 yard.
Subtract 4/8 yard from 7/8 yard to find the remaining length.
7/8 yard - 4/8 yard = 3/8 yard remaining.
So, after using 1/2 yard of ribbon for a craft project, you will have 3/8 yard of ribbon left from the original 7/8 yard piece.

Prove:Sinx-2sin3x+sin5x=2sinx(cos4x-cos2x)
Answers
A = sinx - sin3x,
B = -sin3x + sin5x
First A:
The average of x and 3x is 2x, and they (x and 3x, that is) are each a distance of x from this average. That's fancy talk for:
x = 2x-x,
3x = 2x+x.
So, A = sin(2x-x) - sin(2x+x)
Using angle sum formulas:
A = (sin2x cosx - cos2x sinx) - (sin2x cosx + cos2x sinx)
A = -2 cos2x sinx
Similarly,
B = -sin(4x-x) + sin(4x+x)
= -(sin4x cosx - cos4x sinx) + (sin4x cosx + cos4x sinx)
B = 2 cos4x sinx
Now,
sinx - 2sin3x + sin5x = A+B = -2 cos2x sinx + 2 cos4x sinx
= 2 sinx (cos4x - cos2x).
Sinx-2sin3x+sin5x=2sinx(cos4x-cos2x)
Step-by-step explanation:sinx - 2sin3x + sin5x = sinx - sin(3x) + sin(5x)- sin(3x)
= 2· cos[(x+3x)/2] · sin[(x-3x)/2] + 2·cos[(5x+3x)/2]· sin[(5x-3x)/2]
= 2· cos(2x) ·sin(-x) + 2· cos(4x) · sin(x)
= -2·cos(2x)·sinx + 2· cos(4x)·sinx
= 2·sinx · [ cos(4x)- cos(2x)]
A veterinarian divided 2/5 of a bottle of medicine equally among some sick cats. She gave each cat 1/5 of a bottle of medicine. How many sick cats were there?
Answers
The veterinarian gave each cat 1/5 of a bottle of medicine. By dividing the total medicine (2/5 of a bottle) by 1/5, we find that there were 2 sick cats.
Explanation:To find the number of sick cats, we need to divide the amount of medicine given to the cats by the amount given to each cat. Since each cat received 1/5 of a bottle, we can divide the total medicine (2/5 of a bottle) by 1/5 to find the number of cats. This can be done by multiplying the total medicine by the reciprocal of 1/5, which is 5/1.
Convert 2/5 to an improper fraction: 2/5 = 2 ÷ 5 = 2/5Multiply the total medicine by the reciprocal of 1/5: 2/5 × 5/1 = 2 × 5 / 5 × 1 = 10 / 5 = 2Therefore, there were 2 sick cats.

Katie needs to figure out how much space a shoe box takes up. It is 13 1/2 inches long and 5 inches high and 6 2/3 inches wide. What is the shoe box's volume?
Answers
Answer:
you multiply all three of these numbers to get an answer of 450
Step-by-step explanation:
Final answer:
The volume of the shoe box is calculated using the formula for the volume of a rectangular prism, resulting in a total of 450 cubic inches.
Explanation:
The formula for finding the volume of a rectangular prism (which is the shape of a shoe box) is Volume = Length × Width × Height. However, before calculating, we need to ensure all dimensions are in the same unit. Since the given width is in mixed number form, we will convert 6 2/3 inches to an improper fraction which is 20/3 inches. We then multiply the length, width, and height.
Volume = (13.5 inches) × (20/3 inches) × (5 inches)
Volume = (13.5 × 20/3 × 5) cubic inches
Volume = (270/3 × 5) cubic inches
Volume = (90 × 5) cubic inches
Volume = 450 cubic inches
The shoe box's volume is 450 cubic inches.
