What is the perimeter of ^PQR with vertices P(-2,9) Q(7,-3) and R(-2,-3) in the coordinate plane?
Answers
The perimeter of the given triangle in the coordinate plane is 36 units.
Given:
The triangle PQR with vertices P(-2,9) Q(7,-3) and R(-2,-3) in the coordinate plane.
To find:
The perimeter of the triangle.
Solution:
The distance formula to find the distance between two points () and
():
The distance between point P(-2,9) and Q(7,-3)
The distance between point Q(7,-3) and R(-2,-3)
The distance between point R(-2,-3) and P(-2,9)
The perimeter of the triangle will be given by"
The perimeter of the given triangle in the coordinate plane is 36 units.
Learn more about the distance formula here:
Distance formula: d=√(x-x1)^2+(y-y1)^2
distance of PR: √(-2+2)^2+(9+3)^2= 12
distance of QR: √(7+2)^2+(-3+3)^2=9
distance of PQ: √(7+2)^2+(-3-9)^2= 15
Perimeter: 12+9+15=36

Answer:
No. Both rates did not remain steady.
Step-by-step explanation:
- When Sue had biked 9 laps, Juanita had biked 3 laps. This means that Juanita's rate is 3 laps for every 9 laps Sue bikes.
- When Juanita had completed 12 laps, Sue had completed 30 laps. This implies that Sue's rate is 30 laps for every 12 laps Juanita bikes.
In conclusion, the rates did not remain steady because Sue's rate was significantly faster than Juanita's.

Remember that the slope intercept formula is:
y = mx + b
m is the slope
b is the y-intercept
So far we know the slope and can plug that into the equation like so...
y = -3x + b
Now we must find b
To do that you must plug in the point the line goes through in the x and y of the equation.
(4, -2)
-2 = -3(4) + b
-2 = -12 + b
10 = b
y = -3x + 10

2(4*5+4*9+5*9) =202in^2
Surface Area=202in^2
Lateral Area= Perimeter of base * height
5+5=10 <--width+width
4+4=8 <---length + length
10+8=18 <--total perimeter
18 * 9=162in^2 <--multiplied the height +perimeter of base
Lateral Area=162in^2
2) Same concept as the previous one
Surface Area = 2(lw + lh + wh)
2(4*2+4*5+5*2) =76in^2
Surface Area= 76in^2
Lateral Area
Lateral Area= Perimeter of base * height
4+4=8
2+2=4
8+4=12
12 x 5=60
Lateral Area= 60in^2
#3 tests the concept of surface area. The gift wrap will be covering only the surface of each side. Surface area is all of the outside. Volume is all of the stuff inside.
So the surface area of rectangular prism can be found by the formula:
SA = 2(LW + LH + WH)
SA = 2(9*7 + 7*4 + 9*4)
SA = 2(63 + 28 + 36)
SA = 2(127)
SA = 254 in²
#4 also needs you to find the surface area.
So the surface area of a triangular prism can be found by this formula:
SA = bh + (
SA = (6.3*2) + (6.3 + 2.5 + 5.2)3
SA = 12.6 + (14*3)
SA = 12.6 + 42
SA = 54.6 cm²
