Given:
Midpoint = (2,-14)
One endpoint = (4,-13)
To find:
The another endpoint.
Solution:
Let (a,b) be the another endpoint.
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
Using midpoint formula, we get
[tex](2,-14)=\left(\dfrac{a+4}{2},\dfrac{b+(-13)}{2}\right)[/tex]
[tex](2,-14)=\left(\dfrac{a+4}{2},\dfrac{b-13}{2}\right)[/tex]
On comparing both sides, we get
[tex]2=\dfrac{a+4}{2}[/tex]
[tex]4=a+4[/tex]
[tex]4-4=a[/tex]
[tex]0=a[/tex]
And,
[tex]-14=\dfrac{b-13}{2}[/tex]
[tex]-28=b-13[/tex]
[tex]-28+13=b[/tex]
[tex]-15=b[/tex]
Therefore, the another endpoint is (0,-15).

If f(x) = 5x – 2 and g(x) = x+1, find (f = g)(x).
OA. 5x - x-3
B. 5x2 +1
O C. 5x® - X-1
D. 5x4 - 2
Answers
Answer: Choice A) 5x^3 - x - 3
=================================================
Work Shown:
We subtract the two functions like so
(f - g)(x) = f(x) - g(x)
(f - g)(x) = ( 5x^3-2 ) - ( x+1 )
(f - g)(x) = 5x^3 - 2 - x - 1
(f - g)(x) = 5x^3 - x - 3 ..... choice A
Note: be sure to remember to distribute the negative to every term inside (x+1), and not just to the x only.
This is proportional, true or false? (Proportional means it has an equivalent ratio/constant rate of change/the same rate) (True=yes, it's proportional, false means it is not proportional) y = 12x
Answers
Answer:
Yes/True
Step-by-step explanation:
The given expression is :
y = 12 x
We know that, Proportional means it has an equivalent ratio / constant rate of change / the same rate.
Here,
y ∝ x
12 is the constant of proportionality
Hence, the given expression is proportional.

An architect is making a plan for a new circular playground. If 64 feet is the playground's radius, how much fencing needs to go up to keep the kids in the circle?
100.48 feet
200.96 feet
401.92 feet
Answers
Answer:
209.96
Step-by-step explanation:
we know that the circumference of the circle is equal to
C = [tex]\pi D[/tex]
we have
[tex]D = 64 ft[/tex]
substitute would be
[tex]C = \pi (64) = 64\pi ft[/tex]
assume that [tex]\pi = 3.14[/tex]
64[tex]64\pi = 64 * 3.14 = 200.96 ft[/tex]

Answers
Answer:
131.2 ;
12.8 ;
(118.4, 144)
Step-by-step explanation:
Given :
X = 131.2, s=55 , and n= 50
Point estimate of the mean :
Since, sample size is large (n > 30) ; the sample mean = population mean according to the center limit theorem :
Margin of Error = Zcritical * s / sqrt(n)
Zcritical at 90% = 1.645
Margin of Error : 1.645 * (55 / sqrt(50))
Margin of Error : 1.645 * 7.7781745
Margin of Error = 12.795097
Margin of Error = 12.8
The confidence interval (C.I) :
C.I = x ± margin of error
C. I = 131.2 ± 12.8
(131.2 - 12.8) ; (131.2 + 12.8)
(118.4, 144)

Shane works at an electronics store. he earns 13% comission on his sales. Shane's comission this month $780. what are his total. sales for this mounth?
Answers
Answer:
$6000
Step-by-step explanation:
let's find the unit rate first
we know that 780 is 13% of all his sales so what we can do is find the unit rate
780/13=60 so 1% of all the money is $60
Now we just do simple multiplication; 60*100=6000
So the original sale was $6000
Hope this helped, have a good day!
Answer:
6000
Step-by-step explanation:
780/13 = 60 (100)
= 6000
Which is equivalent to (4 x y minus 3 z) squared, and what type of special product is it
question answer choices are:
A. 16 x squared y squared + 9 z squared, the difference of squares
B. 16 x squared y squared + 9 z squared, a perfect square trinomial
C. 16 x squared y squared minus 24 x y z + 9 z squared, the difference of squares
D. 16 x squared y squared minus 24 x y z + 9 z squared, a perfect square trinomial
Answers
Answer:
The answer is option D
Step-by-step explanation:
When factored out option C and D are the same but it is a perfect square, not the difference of squares.
Option (D) 16 x squared y squared minus 24 x y z + 9 z squared, a perfect square trinomial is the correct answer.
What is an algebraic expression?An expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.). Algebraic expressions include at least one variable and at least one operation.
For the given situation,
The expression is (4xy-3z)^2.
This expression can be expand by using the formula,
[tex](a-b)^{2} = a^{2} -2ab+b^{2}[/tex]
Here, a = 4xy and b = 3z
⇒ [tex](4xy)^{2} -2(4xy)(3z)+(3z)^{2}[/tex]
⇒ [tex]16x^{2} y^{2} -24xyz+9z^{2}[/tex]
Hence we can conclude that option (D) 16 x squared y squared minus 24 x y z + 9 z squared, a perfect square trinomial is the correct answer.
