The coordinates of S are (-1 , 11)
In the given statement is :
The coordinates of point T are (0,4). The midpoint of ST is (1,−3).
To find the coordinates of point S.
Now, According to the question:
Let the coordinate of point S are (x, y).
T (0, 4) is the mid point of ST
=> [tex]\frac{x+1}{2}=0 , \frac{y+(-3)}{2}=4[/tex]
=> x+1 =0 , y -3 = 8
=> x = -1 , y = 11

OA. The slope is (Simplify your answer.)
OB. The slope is undefined.
←
Find the slope of the line passing through the pair of points or state that the slope is undefined. Then indicate whether the line through the points rises, falls, is horizontal, or is vertical
(7.1) and (2.1)
The slope of the line passing through the pair of points is
Given points are:
A (7,1) = (x₁ , y₁)
B (2,1) = (x₂ , y₂)
slope of a line is : y₂ ₋ y₁/x₂ ₋ x₁
Slope equals a height change /Change in width. You may also say that a slope is a climb or a run. This formula changes if the graph's horizontal axis is represented by x and the vertical axis by y.
Assume that the line's slope is'm'.
m = y₂ ₋ y₁/x₂ ₋ x₁
m= 1 ₋ 1/2 ₋ 7
m = 0/₋5
m = 0
hence, when the slope is 0 then the line is horizontal .
Therefore, the slope is 0 which indicates that the line is horizontal.

Tripling the radius of a cylinder find the dimensions, surface area, before change and after change. Help ASAP please !
The dimensions before tripling the radius of the cylinder are:
radius = 2 and height = 7 yd
and surface area = 113.1
The dimensions after tripling the radius of the cylinder are:
radius = 6 and height = 7 yd
surface area = 490.08
Given, we know that the dimensions are:
radius = 2 and height = 7 yd
therefore, surface area = 2πrh + 2πr²
= 2π2×7 + 2π(2)²
= 2×22/7×14 + 2π×4
= 88 + 25.12
= 113.1
After tripling the radius, we get:
radius = 6 and height = 7 yd
therefore, surface area = 2πrh + 2πr²
= 2π6×7 + 2π(6)²
= 2×22/7×42 + 2π×36
= 264 + 226.08

Which of the following sets is NOT closed under addition.
A) Natural Numbers
B) Whole numbers
C) Integers
D) Odd numbers
The odd numbers do not follow the closure property of addition.
What is a closure property of addition?
The closure property of addition states that when any two numbers from the set of reals are added, the result will always be a real number. For example 2 + 3 = 5
Explanation
When we add any two natural numbers, the result is always a natural number, i.e. 2 + 1 = 3. Thus, it follows the closure property of addition.
When we add any two whole numbers, the result is always a whole number, i.e. 3 + 0 = 3. Thus, it follows the closure property of addition.
When we add any two integers, the result is always an integer, i.e. 2 + (-5) = -3. Thus, it follows the closure property of addition.
When we add any two odd numbers, the result is not an odd number, i.e. 3 + 1 = 4. Thus, it does not follow the closure property of addition.
Hence, the odd numbers do not follow the closure property of addition.

At a price of $180 there is demand for 2520 items and a supply of 1440 items. At a price of $330 there is demand for 1470 items and a supply of 2640 items. Assuming supply and demand are linear, find the equilibrium price and quantity.
Assuming supply and demand are linear, the equilibrium price is equal to $252 and the equilibrium quantity is equal to 2,016 items.
What is a linear function?A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.
First of all, we would determine a linear function for both supply and demand by finding the slope using this formula as follows:
[tex]Slope,\;m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope,\;m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]
Note: price (p) in dollars would be the output and quantity (q) would be the input.
For supply, the points include the following:
Points (p, q) = (1,440, 180).Points (p, q) = (2640, 330).Slope, m = (330 - 180)/(2640 - 1440)
Slope, m = 150/1200
Slope, m = 1/8.
Next, we would find the y-intercept at (1,440, 180):
p = qm + c
180 = 1/8(1440) + c
180 = 180 + c
c = 0.
Therefore, the supply equation is p = q/8.
For demand, the points include the following:
Points (p, q) = (2,520, 180).Points (p, q) = (1,470, 330).Slope, m = (330 - 180)/(1,470 - 2,520)
Slope, m = 150/-1,050
Slope, m = -1/7.
Next, we would find the y-intercept at (2,520, 180):
p = qm + c
180 = -1/7(2,520) + c
180 = -360 + c
c = 180 + 360.
y-intercept, c = 540.
Therefore, the demand equation is p = -q/7 + 540.
In order to find the equilibrium price and quantity, we would set the supply equal to the demand:
q/8 = -q/7 + 540
Multiplying all through by 56, we have:
7q = -8q + 30,240
15q = 30,240
q = 30,240/15
Equilibrium quantity, q = 2,016 items.
For the equilibrium price, we have:
p = q/8
p = 2,016/8
Equilibrium price, p = $252.
