If point U is reflected across the x = -3, what are the coordinates of its reflection image?
The coordinates of U after the reflection are: (-5, -3)
How to get the coordinates after the reflection?
By looking at the graph, we can see that the coordinates of point U are:
U = (-1, -3)
And we want to reflect it across the line x = -3.
Notice that because this is a vertical line, the y-component does not change by the reflection. Only changes the x-component, such that the distance between the original coordinates and the final coordinates to the line don't change.
The original x-component is x = -1, the distance to the line is:
d = |-3 - (-1)| = 2 units.
Then the new x-component will also be at 2 units of the line, but in the other direction:
new x-component: x = -3 - 2 = -5
The coordinates of U after the reflection are:
(-5, -3)

The sunshade on one set of equipment has a square base of 120 cm and a height of 50 cm. The
sunshades are open-bottomed square based pyramids. This means that the base is not included.
a. Determine the total surface area, in m², of the sunshade.
The total surface area, in m², of the sunshade is 0.4344 m²
How to calculate surface area of a squared pyramid ?A pyramid can have a squared base, rectangular base or other polygons. The formula we can to find the total surface area of a squared pyramid is
Surface Area = P x l/2
Where
P = base parameterl = slant heightGiven that a sunshade on one set of equipment has a square base of 120 cm and a height of 50 cm. That means that the length L of the base will be 120 cm and half of it will be 60 cm
To find the slant height l, we will use Pythagoras theorem.
[tex]l^{2}[/tex] = 60² + 50²
[tex]l^{2}[/tex] = 3600 + 2500
[tex]l^{2}[/tex] = 6100
l = √6100
l = 78.1 cm
convert it to meter
l = 78.1/100
l = 0.781 m
The perimeter P of the base = 4 x 120/100 = 4.80 m
The Surface Area = P x l/2
Substitute all the necessary parameters into the formula
Surface Area = 4.80 x 0.781/2
Surface Area = 1.8744 m²
If the sunshades are open-bottomed square based pyramids, this means that the base is not included. That is, the area of the base should be taken away from the answer above.
Area of the base = 120/100 x 120/100 = 1.44 m²
The total surface area, in m², of the sunshade will 1.8744 - 1.44
The total surface = 0.4344 m²
Therefore, the total surface area, in m², of the sunshade is 0.4344 m²

The sum of five consecutive integers equals 5.5 times the middle integer. Find the integers.
The five consecutive integers are -2, -1, 0, 1 and 2.
What are the values of the integers?
Given that;
The sum of five consecutive integers equals 5.5 times the middle integer.
Since the integers are consecutive, let the integer be;
x, x+1, x+2, x+3 and x+4.
Now, sum of the integers equals 5.5 times the middle integer.
Middle integer is x+2.
Hence we have;
x + x+1 + x+2 + x+3 + x+4 = 5.5( x+2 )
x + x+1 + x+2 + x+3 + x+4 = 5.5x + 11
We collect like terms
x + x + x + x + x - 5.5x = 11 - 1 - 2 - 3 - 4
5x - 5.5x = 1
-0.5x = 1
x = -( 1 / 0.5 )
x = -2
Since our integers are; x, x+1, x+2, x+3 and x+4.
We substitute in the value of x
x = -2
x+1 = -2 + 1 = -1
x+2 = -2 + 2 = 0
x+3 = -2 + 3 = 1
x+4 = -2 + 4 = 2
Therefore, the five consecutive integers are -2, -1, 0, 1 and 2.

Find the smallest perimeter and the dimensions for a rectangle with an area of 169 in2. Question content area bottom Part 1 The smallest perimeter for a rectangle with an area of 169 in2 is enter your response here in.
The smallest perimeter and dimensions of rectangle having area of 169 [tex]inches^{2}[/tex] is 52 inches , length 16 inches and breadth also 16 inches.
Given that the area of rectangle is 169 [tex]inches^{2}[/tex].
We have to find the smallest perimeter and dimensions of the rectangle.
let the length of rectangle be x inches and breadth be y inches.
We know that area of rectangle is the product of its length and breadth. So,
Area=xy
169=xy
y=169/x
Perimeter of rectangle =2(x+y)
Put the value of y=169/x in the perimeter.
P=2(x+169/x)
P=2x+338/x
Differentiate both sides with respect to x.
dP/dx=2-338/[tex]x^{2}[/tex]
Again differentiate it with respect to x.
[tex]d^{2} P/dP^{2}[/tex]=676/[tex]x^{3}[/tex]
Because the second derivative is greater than 0 so the perimeter is minimum.
Put dP/dx=0 to get the value of x.
dP/dx=0
2-338/[tex]x^{2}[/tex]=0
2=338/[tex]x^{2}[/tex]
[tex]x^{2}[/tex]=169
x=[tex]\sqrt{169}[/tex]
x=13
Put the value of x in y=169/x
y=169/13
=13
To calculate the perimeter, put the values of x and y in P=2(x+y)
P=2(13+13)

The taxi fare for a journey of n miles in dollars is 1 + 2n
What are linear equations?Linear equations are equations that have constant average rates of change, slope or gradient
How to determine the equation of the system?The given parameters about the taxi fares are given as
First two miles = $5
Additional mile = Increment of $2
Let the number of miles be n
So, we have:
2 miles = $5
Additional miles = (n - 2) * 2
Add the above expressions
5 + (n - 2)* 2
Represent the value with f(n)
So, we have:
f(n) = 5 + (n - 2)* 2
Expand the bracket
f(n) = 5 + 2n - 4
Collect the like terms
f(n) = 5 - 4+ 2n
Evaluate the like terns
f(n) = 1 + 2n
Hence, the taxi fare for a journey of n miles in dollars is 1 + 2n
So, the complete parameters are:
First two miles = $5
Additional mile = Increment of $2

D is the centroid of triangle abc. what is the value of x when bd=2x+40 and bf=18x
The value of x= 20 units
BD = BF
BD =2x + 40
BF = 18x
Equate the expressions thus:
2x + 40 = 2/3(18x)
2x + 40 = 12x
Collect like terms
2x - 12x = - 40
-2x = - 40
Divide both sides by - 2
x = 20
Hence, x = 20 units
The centroid is the center point of the item. The factor in which the 3 medians of the triangle intersect is known as the centroid of a triangle. it is also defined because of the point of intersection of all the 3 medians. The median is a line that joins the midpoint of a facet and the opposite vertex of the triangle.
Then, we can calculate the centroid of the triangle by means of taking the common of the x coordinates and the y coordinates of all of the three vertices. So, the centroid method can be mathematically expressed as G(x, y) = ((x1 + x2 + x3)/3, (y1 + y2 + y3)/three).
The centroid of a triangle is the point at which the 3 medians coincide. The centroid theorem states that the centroid is 23 of the space from each vertex to the midpoint of the opposite aspect.

Can you please find x?
Answer:
x=7
Step-by-step explanation:
The angle of a straight line is 180 degrees, so let's just say the other angle to the right of 15x+34 is "a" that means that 15x + 34 + A = 180, and since the sum of interior angles of a triangle is 180 degrees, that means that 29 + A + 12x + 26 = 180, and we can define A using this equation in terms of x.
Original equation (sum of interior angles)
A + 29 + 12x + 26 = 180
Combine like terms
A + 12x + 55 = 180
Subtract 12x and 55 from both sides
A = -12x + 125
Original equation (since a line is 180 degrees)
15x + 34 + A = 180
Substitute -12x + 125 as A
15x + 34 + (-12x + 125) = 180
Combine like terms
3x + 159 = 180
Subtract 159 from both sides
3x = 21
Divide both sides by 3
x = 7

for some integer [tex]k[/tex].
The largest value of [tex]2a+2b+c[/tex] is 2•8 + 2•9 + 9 = 43, so we must have [tex]k\in\{1,2,3,4\}[/tex].
I'm not sure what the best way to get the final count may be, but there are 44 such numbers. It's rather tedious to do by hand.
• If [tex]k=1[/tex], then [tex]2a+2b+c=9[/tex], and we can do this in 4 ways.
For example,
2•2 + 2•0 + 5 = 9 [tex](n = 20502)[/tex]
• If [tex]k=2[/tex], then [tex]2a+2b+c=18[/tex] and can be done in 16 ways.
2•2 + 2•3 + 8 = 18 [tex](n = 23832)[/tex]
• If [tex]k=3[/tex], then [tex]2a+2b+c=27[/tex] and can be done in 18 ways.
2•2 + 2•7 + 9 = 27 [tex](n = 27972)[/tex]
• If [tex]k=4[/tex], then [tex]2a+2b+c=36[/tex] and can be done in 6 ways.
2•6 + 2•8 + 8 = 36 [tex](n = 68886)[/tex]
