Which scatter plot represents the data in the table?

1 answer:

4 0

In order to answer this question, you need to know what should be in the x axis and what should be in the y axis.

As for this one, you have given the information of the table:<span>
Park patrons Number of dogs
7 4
6 2
9 7
8 6
5 3
7 7
3 1
4 3

The value in the x axis should be the </span>Park patrons
The value in the y axis should be the Number of dogs

Hey there,

Question #1

The answer would be in the attachment below.
_____________________________________________________________

Question #2

The answer would be in the attachment below.

Question #3

The answer would be in the attachment below.
_____________________________________________________________

Question 4#

The last one was kind of tricky. But, as I saw this attachment, I noticed on how the rectangle was actually 3/4 on the base and for the height, it was 1/2. So by doing this,we need to find the area, and we would multiply these both. 1/2 x 3/4 = 3/8 but by looking at your options, those are not simplified so . . .your answer would be 6/16 because 3x2=6 & 8x2=16.

I really hope this can help you Amanda.

Have a great day! =)

Find the area of the semicircle need help asapp

sergij07 [2.7K]

Answer:

2 pi

Step-by-step explanation:

The radius is 2

The area of a circle is

A = pi r^2

We have 1/2 of a circle so

1/2 A = 1/2 pi r^2

=1/2 pi ( 2)^2

=1/2 pi *4

= 2 pi

A 40-m-long chain hangs vertically from a cylinder attached to a winch. Assume there is no friction in the system and the chain

daser333 [38]

Answer:

a) W₁ = 78400 [J]

b)Wt = 82320 [J]

Step-by-step explanation:

a) W = ∫ f*dl general expression for work

If we have a chain with density of 10 Kg/m, distributed weight would be

9.8 m/s² * 10 kg = mg

Total length of th chain is 40 m, and the function of y at any time is

f(y) = (40 - y ) mg where ( 40 - y ) is te length of chain to be winded

At the beggining we have to wind 40 meters y = 0 at the end of the proccess y = 40 and there is nothing to wind then:

f(y) = mg* (40 - y )

W₁ = ∫f(y) * dy ⇒ W₁ = ∫₀⁴⁰ mg* (40 - y ) dy ⇒ W₁ = mg [ ∫₀⁴⁰ 40dy - ∫₀⁴⁰ ydy

W₁ = mg [ 40*y |₀⁴⁰ - 1/2 * y² |₀⁴⁰ ⇒ W₁ = mg* [ 40*40 - 1/2 (40)² ]

W₁ = mg * [1/2] W₁ = 10*9,8* ( 800 )

W₁ = 78400 [J]

b) Now we can calculate work to do if we have a 25 block and the chain is weightless

W₂ = ∫ mg* dy ⇒ W₂ = ∫₀⁴⁰ mg*dy ⇒ W₂ = mg y |₀⁴⁰

W₂ = mg* 40 = 10*9.8* 40

W₂ = 3920 [J]

Total work

Wt = W₁ + W₂ ⇒ Wt = 78400 + 3920

Wt = 82320 [J]
