Answer:
0
Step-by-step explanation:
let (-3,2) be (x1,y1)
and(3,2)be(x2,y2)
Now,
slope = y2-y1/x2-x1
=2-2/3-(-3)
=0/3+3
=0/6
therefore slope=0
The length of a rectangle is four times its width. If the perimeter of the rectangle is 90 cm, find its area
Answer:
324
Step-by-step explanation:
L = 4W
P = 2L + 2W = 90
---
2L + 2W = 90
2(4W) + 2W = 90
8W + 2W = 90
10W = 90
---
W = 9
L = 36

A = 324

Answer:
The area of the rectangle is 324 square centimeter.
Step-by-step explanation:
What is area?
The area is the amount of space within the perimeter of a 2D shape.
What is rectangle?
A rectangle is a two-dimensional shape (2D shape) in which the opposite sides are parallel and equal to each other and all four angles are right angles.
What is perimeter?
Perimeter is the distance around the edge of a shape.
Let the width of the rectangle be x cm.
Then, the length of the rectangle = 4xcm
Perimeter = 2(length + breadth )
90 = 2(4x+x)
90 = 2*5x
90 = 10x
x = 90/10= 9cm
Width = 9cm
Length = 4*9 = 36 cm
Area = Length*Breadth
=9*36
=324 square centimeter.

If f(x) = 2x – 5 and g(x) = x +4, then f(g(2)) =
Answer:
7
Step-by-step explanation:
f(g(2))
f(x+4) and you would replace x with two, so you would get
f(2+4) = f(6)
You would then plug in 6 for the x in the f(x) equation:
2(6) - 5 = 12-5 = 7

Tyler claims that because he started painting first he will finish painting his side of the fence before Benito finishes painting his side. Is this true? Explain
Answer:
but
Step-by-step explanation:
yrge sksue dnd djd d d. r e g g h a s. v j u r d. d c g y t
Tyler's claim about finishing his painting first is False because it will take Benito 10 minutes while Tyler will require over 11 minutes to finish up his painting despite starting before Benito.
Size of fence = 150 feet
Benito's rate = 15 ft/min
Tyler's rate = 11 ft/ min
Size already painted by Tyler when Benito started = 39/2 = 19.5 ft
Portion of fence left for Tyler to paint when Benito started = (150 - 19.5) = 130.5 feets
Time required for Tyler to finish :
Time required = 130.5 ÷ 11 = 11.863 minutes
Time required for Benito to finish :
Time required = 150 ÷ 15 = 10 minutes
Time required for Benito to complete his painting is lesser than Tyler's (10 < 11.863)
Hence, Tyler's claim is False

Use traces to sketch the surface. x2 = y2 + 5z2
Answer:
when k > 0 the traces parallel to the yz plane is an ellipse
The traces parallel to the xz plane are parabolas and they open in positive x- axis direction
The traces parallel to the xy plane are parabolas that open in the positive x-axis direction
Step-by-step explanation:
Given surface : [tex]x^2 = y^2 + 5z^2[/tex]
To determine the traces of the given equation we will have to make some assumptions and the assumption is
let x = k
[tex]k^2 = y^2 + 5z^2[/tex]
when k > 0 the traces parallel to the yz plane is an ellipse
let y = k
[tex]x^2 = k^2 + 5z^2[/tex]
The traces parallel to the xz plane are parabolas and they open in positive x- axis direction
Let z = k
[tex]x^2 = y^2 + 5k^2[/tex]
The traces parallel to the xy plane are parabolas that open in the positive x-axis direction
with the given traces The surface can be sketched
The midpoint of AB is M=(3, 1). One endpoint is A=(-1, -1).
Find the coordinates of the other endpoint, B.
Answer:
(7, 3)
Step-by-step explanation:
Given segment AB, where:
A = (-1, -1)Mid point
M = (3, 1)Point B = (x, y)As per mid point formula:
(-1+x)/2 = 3 ⇒ -1 + x = 6 ⇒ x = 6+ 1 = 7(-1 + y)/2 = 1 ⇒ -1 + y = 2 ⇒ y = 2 + 1 = 3So, the point B is:
B = (7, 3)Use the sample data and confidence level given below to complete parts (a) through (d).

Complete question :
A study is conducted to assess the smoking behaviors of high-school seniors. A random sample of 8 seniors is selected and each student is asked the number of cigarettes consumed on a typical day. The (sorted) sample is: 0 0 3 4 5 8 10 18. If 18 is replaced with 20, then select all that apply:
Sample IQR will change
Range, IQR, and standard deviation will remain the same
Sample range will change.
Sample standard deviation will change
Answer:
Sample range will change
Sample Standard deviation will change
Step-by-step explanation:
Given the sorted sample : 0,0,3, 4,5,8,10, 18
n = number of observations
Sample range : ( 18 - 0) = 10
Upper quartile (Q3) = 3/4(n+ 1) = 3/4(9) th term
Q3 = 27/4 = 6.75th term
(8 + 10) / 2 = 18/ 2 = 9
Lower quartile (Q1) = 1/4(n + 1) = 9/4 th term
2.25th term = 0+3 = 3/2 = 1.5
Interquartile range = 9 - 1.5 = 7.5
Standard deviation = 5.976 (using calculator)
If 18 is replaced by 20:
0,0,3, 4,5,8,10, 20
Range = (20 - 0). = 20
Upper quartile (Q3) = 3/4(n+ 1) = 3/4(9) th term
Q3 = 27/4 = 6.75th term
(8 + 10) / 2 = 18/ 2 = 9
Lower quartile (Q1) = 1/4(n + 1) = 9/4 th term
2.25th term = 0+3 = 3/2 = 1.5
Interquartile range = 9 - 1.5 = 7.5
Standard deviation = 6.563 (using calculator)

Answer:
80.4
Step-by-step explanation:
You have to first find the area of the circle which the formula for that is pi r^2. So you would set it up as 3.14 (2.5)^2 which you then would solve and get 19.625. Then, you find the area of the square which is length times width. So then you would multiply 10 and 10 and get 100. You then subtract 100 and 19.625 which gives you 80.375 but since it says round to the nearest tenth you'd get 80.4.
Step-by-step explanation:
For no.1
