Given that,
To one decimal place, round.
A(-4, 6), B(3, -7), E(-6, -5) and F (2, 0).
We have to find the distance between two points that are AB and EF.
1. The distance between 2 points A and B.
A(-4, 6) and B(3, -7).
Distance formula is [tex]\sqrt{(x_{2} -x_{1} )^{2} +(y_{2} -y_{1} )^{2} }[/tex]
Here, x₁=-1,x₂=3 and y₁=6,y₂=-7
After substituting we get,

A location that is 30 degrees north and 45 degrees west is west of the prime meridian and north of the equator.
A prime meridian refers to an arbitrary meridian which is there in a geographic coordinate system. Here, the longitude is defined as 0°.
A prime meridian and its anti-meridian will together form a great circle in a geographic coordinate system.
The Equator is a circle of latitude, about 40,075 km in circumference, that divides Earth into the Northern and Southern hemispheres.
It is an imaginary line that is located at 0 degrees latitude, and is a halfway between the North and South poles.

Philip's mistake is he did not add zero at ten's place.
When the multiplication is performed with two or more digits in the bottom number, zeroes are added as per the position. We see that in number 21, one is at one's place and 2 is at ten's place. Hence, when multiplying the digit 2 with the number 1659, we will add zero at one's place.
Performing the correct multiplication -

The result of multiplication will be the sum of numbers 1659 and 33180.

Answers
The coordinates of A'' will be ( -2, 5).
We are given that:
Quadrilateral ABCD is reflected across the x - axis.
We know that, when a refection is done about x-axis, the values of the abscissa x remain identical & the value of ordinate just change their signs:
A(-5,-3) will become A'(-5,+3)
B(-6,-1) will become B'(-6,+1)
C(-3,-1) will become C'(-3,+1)
D(-2,-3) will become D'(-2,+3)
Now, the reflected quadrilateral A'B'C'D' is then translated 3 units right and 2 units up to form quadrilateral A"B"C"D".

the midpoint of \overline{\text{ab}} ab is m(0, -3)m(0,−3). if the coordinates of aa are (2, 1)(2,1), what are the coordinates of bb?
Answers
If the coordinates of the point a is (2,1) and midpoint is (0.-3), then the coordinates of b is (-2,-7).
Midpoint:
Midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints.
The formula for midpoint is,
[tex](x_{m},y_{m})= (\frac{x_{1}+x_{2} }{2} ,\frac{y_{1}+y_{2} }{2} )[/tex]
Where
(x₁,y₁) is the coordinates of the first point and
(x₂,y₂) is the coordinates of the second point
and
[tex](x_m,y_m)[/tex] is the mid point of the first and second points.
Given,
Mid point = (0,-3)
Point a = (2,1)
Here we need to find the point b.
Let (x,y) be the point of b.
Now,
Apply the values on the formula,
Then we get,
[tex](0,-3)=(\frac{2+x}{2},\frac{1+y}{2})[/tex]
Compare the values in order to solve it,
=> 0 = (2 +x)/ 2
=> 0 = 2 + x
=> x = -2
Similarly,
=> -3 = (1 + y)/2
=> -3 x 2 = 1 + y
=> -6 = 1 + y
=> y = -6 - 1
=> y = -7
Therefore, the coordinates of b is (-2,-7).

Answers
Yes, it is true that if "x" is an optimal solution to a linear programming problem, then it is a vertex of the feasible region.
Linear programming (LP) is one of the most basic methods of optimization. By making a few simplifying assumptions, it can assist you in solving some highly complicated optimization issues.Linear programming is a basic approach that uses linear functions to represent complicated connections and then finds the optimum spots.Linear programming is used to find the best solution to a problem given certain limitations. In linear programming, we transform a real-world issue into a mathematical model. It consists of an objective function, linear inequalities, and constraints.A graphical technique entails constructing a collection of linear inequalities that are constrained. The disparities are then plotted on an X-Y plane. When we plot all of the inequalities on a graph, the intersecting region provides us with a viable region. The viable region describes all of the values that our model may take. It also provides us with the best solution.At the point of intersection, when the constraints are active, the best viable solution is found. This signifies that the intersection of the equations provides the best answer.

What’s the domain and range ??
USE INTERVAL NOTATION.
Only answer if you know!
Answers
Domain: (-∞, ∞)
Range: (-∞, ∞)
Step-by-step explanation:Domain and range help us describe the values a graph covers.
Defining Domain and Range
The domain is defined as all the x-values included in a function.The range is defined as all of the y-values included in a function.Remember that the x-values are along the horizontal axis, and the y-values are on the vertical axis.
The function given to us extends infinitely to the left and right as shown by the arrows. Additionally, the graph extends up and down infinitely; thus the range is also infinite.
Interval Notation
Interval notation should be written as (minimum value, maximum value). If the minimum and maximum values are included within the range or domain, then the parentheses should be replaced with brackets. This looks like [included minimum, included maximum]. Since a function cannot actually include infinity, an infinity symbol should never have brackets.
Eventually, this linear function will reach every single x and y-value in existence. So, both axes have a minimum of -∞ and a maximum of ∞. Thus, both the domain and range are (-∞, ∞).
Hint for future problems: all linear functions will have a domain and range of (-∞, ∞).

Step-by-step explanation:
I would suggest starting with 1 and working to 4, as it is set up for you like that.
I would start by writing down what you know, then what you need as follows:
[tex]Givens:\\ C_{ost}=13x+50;\\ R_{evenue}=36x;\\P_{rofit}=R_{evenue}-C_{ost};\\ x=N_{umber\ of\ animals}\\[/tex]
[tex]Find:\\1.\ Profit\ equation\\2a.\ C_{ost}\ to\ make\ 70\ animals\\2b.\ P_{rofit}\ from\ selling\ 70\ animals\\3a.\ C_{ost}\ to\ make\ 100\ animals\\3b.\ P_{rofit}\ from\ selling\ 100\ animals\\4.\ N_{umber}\ of\ animals\ needed\ to\ produce\ P_{rofit}\ of\ \$1100[/tex]
Now you can read it easier. Given that Profit is Revenue minus Cost, plug the equations for Cost and Revenue into the Profit equation as follows:
[tex]P_{rofit}=36x-(13x+50)\\NOTE:\ Do\ NOT\ forget\ to\ put\ the\ C_{ost}\ equation\ in\ parenthesis\ as\ you\ \\must\ subtract\ the\ entire\ C_{ost}.\\\\Distribute\ the\ negative:\ P_{rofit}=36x-13x-50\\Combine\ like\ terms:\ P_{rofit}=13x-50[/tex]
With the Profit equation, it is now easier to solve 2b, 3b, and 4.
[tex]C_{ost}\ for\ 70: C_{ost}=13(70)+50=(700+210)+50\\NOTE:\ I\ used\ the\ fact\ that\ 13*70=(10+3)*70=10*70+3*70\\C_{ost}=910+50=960\\This\ could\ also\ be\ written\ more\ clearly\ as\ C_{ost}(70)=960\\\\P_{rofit}(70) = 13(70)-50\\P_{rofit}(70)=(700+210)-50\\P_{rofit}(70)=910-50\\P_{rofit}(70)=860\\\\C_{ost}(100)=13(100)+50\\C_{ost}(100)=(1300)+50\\C_{ost}(100)=1350\\\\P_{rofit}(100)=13(100)-50\\P_{rofit}(100)=(1300)-50\\P_{rofit}(100)=1250\\[/tex]
Problem 4 will involve using the (now) known amount for profit, $1100 to find the unknown number of animals. This will involve a little bit more "algebra" compared to the prior questions.
[tex]P_{rofit}(x)=1100=13x-50\\1100=13x-50\\[/tex]
Because 13x - 50 is 1100, 13x will be 1100 + 50, just as
[tex]5*2+10 = 20\\5*2=20-10\\[/tex]
So, add 50 to both sides:
[tex]1100+50=13x-50+50\\1150=13x\\[/tex]
Because 13x is 1150, x will be 1150÷13, just as
[tex]5*2=10\\5=\frac{10}{2}[/tex]
So, divide 13 from both sides:
[tex]\frac{1150}{13}=\frac{13x}{13}\\\\\frac{1150}{13}=x[/tex]
Because 1150/13 is not an integer, use a calculator, or simplify the improper fraction to obtain...
x=88.5 (Approximately)

Answer:
Final answer: P=(1,5)
Step-by-step explanation:
The line APB is a line such that AP/PB= 1/3. From the points A and B that we have we can find the distance between those points using the formula d= [(y2-y1)^2=(x2-x1)^2]^1/2
d= 4 (13)^(1/2)
Now the ratio is 1:3. AP= sq rt(13) and PB= 3 sq rt(13)
Using mid point formula the mid point of AB (say Q) = [(-1+7)/2,(2+14)/2]= (3,8).
Hence the mid point of AQ is P which can found out again using the mid point formula
P= [(-1+3)/2,(2+8)/2]= (1,5)
