The given line segment has a midpoint at (3, 1).
What is the equation, in slope-intercept form, of the perpendicular bisector of the given line segment?
y = x
y = x – 2
y = 3x
y = 3x − 8
The equation, in slope-intercept form, of the perpendicular bisector is: y = 1/3x.
What is the Slope-intercept Form of an Equation?The slope-intercept form is given as, y = mx + b.
b is y-intercept, and m is the slope.
Slope = change in y/change in x.
The slopes of two lines that are perpendicular to each other are negative reciprocal of each other.
Thus, let's find the slope of the blue line:
Slope = (-2 - 4)/(4 - 2) = -3
Therefore, the slope of the line perpendicular to it would be, 1/3.
Equation of the perpendicular bisector that passes through (3, 1):
Since slope (m) is 1/3, find b by substituting m = 1/3 and (x, y) = (3, 1) into y = mx + b.
Thus:
1 = 1/3(3) + b
1 = 1 + b
1 - 1 = b
b = 0.
Substitute b = 0, and m = 1/3 into y = mx + b:
y = 1/3x + 0
y = 1/3x
Therefore, the equation, in slope-intercept form, of the perpendicular bisector is: y = 1/3x.

Which of these triangle pairs can be mapped to each other using a single translation?
pls help need it fast
Answer:- D shows the triangle pairs which can be mapped to each other using a single translation.
Explanation:-
Translation is a rigid transformation which creates a congruent image as that of the original figure such that the distance between the each point of the original figure and the image is fixed and same.
The translation mapping is given by (x,y)→(x+h,y+k) ,where h is the distance of the x coordinate of the each point of the original figure to the image and k is the distance of the y coordinate of the each point of the original figure to the image.
In figure D we can see that the distance between each point of ΔCED is equal to the distance between each point of ΔMPN. Thus it shows the triangle pairs which can be mapped to each other using a single translation.
The Figure 4 is correct as the triangle MNP and CDE can be mapped to each other using a translation.
Further explanation:
Translation can be defined as to move the function to a certain displacement. If the points of a line or any objects are moved in the same direction it is a translation.
Explanation:
The angle MNP is equal to the angle CDE.
The side PN is equal to the side ED.
The side MN is equal to the side CD.
The translation mapping of a single translation can be expressed as follows,
[tex]\left( {x,y}\right) \Rightarrow \left({x + h,y + k} \right)[/tex]
Here, h represents the distance of translation in x-axis and k represents the distance of translation in y-axis.
In Figure 1 the triangle MNP and CDE cannot be mapped to each other using a single translation.
In Figure 2 the triangle MNP and CDE cannot be mapped to each other using a single translation.
In Figure 3 the triangle MNP and CDE cannot be mapped to each other using a single translation.
In Figure 4 the triangle MNP and CDE can be mapped to each other using a translation.
Hence, the Figure 4 is correct as the triangle MNP and CDE can be mapped to each other using a translation.

The path of a football kicked by a field goal kicker can be modeled by the equation y = –0.03x2 + 1.53x, where x is the horizontal distance in yards and y is the corresponding height in yards. What is the football’s maximum height? Round to the nearest tenth. yds. How far is the football kicked? yds.
Answer:
Maximum height achieved by football = 25.5 yards.
Distance traveled by football 51 yards.
Step-by-step explanation:
Path of a football kicked by a field goal kicker can be modeled by the equation y = -0.03x² + 1.53x.
Where x represents horizontal distance and y represents height of the football.
For maximum, height we will find the [tex]\frac{dy}{dx}[/tex] ( derivative ) of the equation and equate it to zero.
[tex]\frac{d(y)}{dx}[/tex] = [tex]\frac{d}{dx}[/tex] (-0.03x² + 1.53x )
[tex]\frac{dy}{dx}[/tex] = -0.03 × 2x + 1.53
By putting [tex]\frac{dy}{dx}[/tex] = 0
-0.06x + 1.53 = 0
0.06x = 1.53
x = [tex]\frac{1.53}{0.06}[/tex] = 25.5 yards
Therefore, maximum height achieved by the ball is 25.5 yards.
Now for horizontal distance covered by ball y should be 0
-0.03x² + 1.53x = 0
x ( 1.53 - 0.03x ) = 0
0.03x = 1.53
x = [tex]\frac{1.53}{0.03}[/tex] = 51 yards.
Football was kicked 51 yards.

The Smiths want to buy a 9 ft. by 12 ft. carpet and center it in a 15 ft. by 20 ft. room.
If the Smith's want to use square tiles, which are 6 inch on each side, in the area not covered by the carpet, how many tiles will they need?
Answer:
Correct answer is 768 tiles.
The Smiths would need 768 tiles to cover the area not occupied by the carpet in their 15 ft by 20 ft room.
Explanation:To solve this problem, let's first understand the dimensions. The room is 15 ft by 20 ft which gives a total space of 300 ft2. The carpet is 9 ft by 12 ft, so it will cover an area of 108 ft2.
We subtract the area of the carpet from the total area of the room to find the area that needs to be covered with tiles: 300 ft2 - 108 ft2 = 192 ft2.
Each square tile measures 6 inches by 6 inches. We must convert this to feet, as our other measurements are in feet. So, each tile is 0.5 ft by 0.5 ft, giving an area of 0.25 ft2 per tile.
Finally, we divide the total tile area needed (192 ft2) by the area of each tile (0.25 ft2). This gives us: 192 ÷ 0.25 = 768 tiles.

How do you write an equation in slope intercept form when the slope is undefined?
When the slope is undefined, write the equation as x = c, where c is the constant value of the x-coordinate for all points on the vertical line.
When the slope of a line is undefined, it means that the line is vertical. In the slope-intercept form of a linear equation, y = mx + b, m represents the slope of the line. However, when the slope is undefined (infinite), you cannot express it as a finite value m.
For a vertical line passing through a point (a, b), the equation can be written as: x = a.
In this case, there is no slope term, because the line is vertical and does not have a slope in the traditional sense. Instead, the equation simply states that for all points on the line, the x coordinate remains constant at a.
Thus, when the slope is undefined, write the equation as x = c, where c is the constant value of the x-coordinate for all points on the vertical line.
If the sum of five consecutive even integers is t, then, in terms of t, what is the greatest integer?
The greatest integer is t/5 + 4 in terms of t.
What are Integers?Integers are numbers which includes the set of natural numbers, o and the negatives of all those natural numbers.
Set of integers are usually denoted as Z.
Let the first even integer be x.
Then the consecutive even integer is x + 2.
Integers are x, x + 2, x + 4, x + 6 and x + 8.
Given, sum of five consecutive even integers is t.
x + x + 2 + x + 4 + x + 6 + x + 8 = t
5x + 20 = t
5 (x + 4) = t
x + 4 = t / 5
Greatest integer is x + 8.
x + 8 = (x + 4) + 4 = t/5 + 4
Hence the greatest integer is t/5 + 4.

Carrie is an American teaching English in Mexico, and she currently has 45,000 pesos in her bank account. If the exchange rate changes from 1 U.S. dollar = 12.94 Mexican pesos to 1 U.S. dollar = 13.09 Mexican pesos, what happens to the value in U.S. dollars of the money in Carrie's bank account?
Answer:
Because of change in conversion rates, the value in Carrie's account decreases by $39.85.
Step-by-step explanation:
Total money in Carrie's bank account = 45000 pesos.
If exchange rate is 1 USD = 12.94 pesos, then in dollars the money in account is :
[tex]\frac{45000}{12.94}[/tex] = $3477.588 ≈ $3477.59
If exchange rate is 1 USD = 13.09 pesos, then in dollars the money in account is :
[tex]\frac{45000}{13.09}[/tex] = $3437.738 ≈ $3437.74
Now, if the conversion rate is 12.94 pesos then the amount in dollars is more, than when the conversion rate is 13.09 pesos.
The difference is [tex]3477.59-3437.74=39.85[/tex] dollars.
So, because of change in conversion rates, the value in Carrie's account decreases by $39.85.
