Answer:
Step-by-step explanation:
Given the points R(-4, 5) and S(2, -1), to get the distance between the points, we will use the formula;
D = √(x2-x1)²+(y2-y1)²
Given x1= -4, y1 = 5, x2 = 2 and y2 = -1
RS = √(2-(-4))²+(-1-5)²
RS = √(6)²+(-6)²
RS = √36+36
RS = √72
RS = √2×36
RS = 6√2units
To get the midpoint, we will use the formula M(X,Y) = (x1+x2/2, y1+y2/2)
(X,Y) = (-4+2/2, -1+5/2)
(X,Y) = (-2/2, 4/2)
(X,Y) = (-1,2)
Hence the midpoint is (-1,2)
To get a point P 1/3 of the distance of RS, we will multiply 1/3 with the the distance RS as shown
P = 1/3 × 6√2
P = 2√2
(-1)² + (-2) + (-3)² + (-4)²

13 58
so if PQ + QR = PR, than 13+58=PR
13+58=71
PR=71
The value of the segment PR will be 71.
What is a line segment?A line segment in geometry is a section of a line that has two clearly defined endpoints and contains every point on the line that lies within its confines.
Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that the value of the segment Qr=58 and pq=13. The value of segment PR will be calculated as below:-
PR = QR + PQ
PR = 13 + 58
PR = 71
Therefore, the value of the segment PR will be 71.

A company manufactures and sells shirts. The daily profit the company makes depends on how many shirts they sell. The profit, in dollars, when the company sells x x shirts can be found using the function f ( x ) = 8 x − 40. F(x)=8x−40. Find and interpret the given function values and determine an appropriate domain for the function.
Answer:
Domain = [0, ∞).
Step-by-step explanation:
he profit, in dollars, when the company sells x shirts can be found using the function
[tex]f(x)=8x-40[/tex]
For x=0,
[tex]f(0)=8(0)-40=-40[/tex]
It means, if company sells 0 shirts, then company makes loss (because of negative sign) of $40.
For x=5,
[tex]f(5)=8(5)-40=0[/tex]
It means, if company sells 5 shirts, then company makes profit of $0 means no loss no profit.
For x=10,
[tex]f(10)=8(10)-40=40[/tex]
It means, if company sells 10 shirts, then company makes profit of $40.
Domain is the set of input values.
We know that number of shirts can not be negative, therefore the value of x is always greater than or equal to 0.
Domain = [0, ∞).
Therefore, the domain for the function is [0, ∞).

The ratio of red marbles to blue marbles is 3:5. If there are 225 blue marbles total in the collection, how many of each color are there? Please show your work.
Answer:
Red balls = 84 Blue balls = 140
Step-by-step explanation:
Ok so there are 225 marbles
And ratio here is Red : Blue = 3 : 5
So Red marbles = 3x whereas Blue marbles = 5x
Therefore,
3x + 5x = 225
8x = 225
x = 28.125 = 28
Red balls = 28*3 = 84 Blue balls = 28*5 = 140
(Pls check whether total no of balls is 224)
HELP !!! Evaluate f(-2) for the function f(x) = 3x2 + 2x - 5
Answer:
3
Step-by-step explanation:
So we have the function:
[tex]f(x)=3x^2+2x-5[/tex]
To evaluate the value of f(-2), substitute -2 for x. Thus:
[tex]f(-2)=3(-2)^2+2(-2)-5[/tex]
Square first:
[tex]f(-2)=3(4)+2(-2)-5[/tex]
Multiply:
[tex]f(-2)=12-4-5[/tex]
Now, subtract:
[tex]f(-2)=8-5=3[/tex]
So:
[tex]f(-2)=3[/tex]

PLZ HELP!!!! A pair of equations is shown below: y = 6x − 4 y = 5x − 3 Part A: In your own words, explain how you can solve the pair of equations graphically. Write the slope and y-intercept for each equation that you will plot on the graph to solve the equations. (6 points) Part B: What is the solution to the pair of equations? (4 points)
Answer:
Step-by-step explanation:
y = 6x − 4
y = 5x − 3
A: chose a value for x(input) and get the out put (y) because the equation already in the slope intercept mode:y=mx+b
x y=6x-4 y=5x-3
1 y=2 y=2
2 y=8 y=7
0 -4 -3
slope :
y=6x-4 slope is 6 y intercept(0,-4)
y=5x-3 slope is 5 y intercept (0,-3)
solution of the pair of equation is the point of intersection :
6x-4=5x-3
6x-5x=-3+4
x=1 and y=6x-4 ⇒ y=6-4=2

13 If B is the midpoint of AC, and AC = 8x – 20,
find BC.
3x-1
А в
Answer:
BC = 26
Step-by-step explanation:
Given that:
B is the midpoint of AC
Then AC = AB + BC
AC = 8x - 20 and AB = 3x - 1
Then,
8x - 20 = (3x - 1) + BC
8x - 20 - (3x - 1) = BC
8x - 20 - 3x + 1 = BC
5x - 19 = BC
But AB = BC
5x - 19 = 3x - 1
5x - 3x = - 1 + 19
2x = 18
x = 9
Hence,
Since BC = AB = 3x - 1
3(9) - 1
27 - 1
= 26

The circumference of a quarter is approximately 7.54 mm. What is its diameter to the nearest tenth of a millimeter? (π = 3.14)
Answer:
2.40mmStep-by-step explanation:
In this problem. we are required to solve for the diameter of a circle.
Given data
circumference of circle c= 7.54mm
we know that the expression for the circumference is given as
c= 2πr
We can substitute our given data to solve for r
7.54= 2*3.142*r
7.54=6.284*r
divide both sides by 6.284 we have
r= 7.54/6.284
r= 1.199
diameter = 2*r
diameter= 1.199*2
diameter= 2.399
to the nearest tenth
diameter= 2.40mm

(6a - 10) = 12 – (6 - 3a), when b=11
A = ?
Answer:
a = 5.333.. or 5 1/3
Step-by-step explanation:
I am not sure what your question is but it looks like you need to solve for a.
Based on that fact:
6a - 10 = 12 - 6 + 3a you multiply -1 by each term in the parenthesis
Then it is simple algebra
6a -10 = 6+ 3a
+10 + 10 add 10 to both sides
6a = 16 + 3a
-3a -3a add -3a to both sides
3a = 16 Divide both sides by 3
a = 5.3333
