Answer:

$I~am~here!!!$

C. ⇒ 2 : 4. This is because 2 may be a multiple of 1, however, 3 is not a direct multiple of 4.

C. Because is 1:3 started with a 2 it would have to be 2:6 and 1:3 can not convert into 2:4

Answer:

Answer is in the pic

Step-by-step explanation:

A translation is just a movement of the figure so in this case you just add 3 to the x part of the coordinate.

so originally k (-2,5) m (-3,1) l (1,1)

add 3 to x so

k (1,5) m (0,1) l (4,1)

A variable force of 3x−2 pounds moves an object along a straight line when it is x feet from the origin. Calculate the work done

Verdich [7]

Answer:

$2.70J$ .

Step-by-step explanation:

We have been given that a variable force of $3x^{-2}$ pounds moves an object along a straight line when it is x feet from the origin. We are asked to find the work done in moving the object from x = 1 ft to x = 10 ft.

We know that $dW=Fdx$ , where F represents force.

$dW=3x^{-2}dx$

Now, we will integrate both sides of equation as:

$\int\limits{dw} =\int\limits^{10}_1 {3x^{-2} \, dx$

Take the constant out:

$\int\limits{1dw} =3\int\limits^{10}_1 {x^{-2} \, dx$

$w =3\int\limits^{10}_1 {x^{-2} \, dx$

Upon applying power rule of integrals, we will get:

$w =3\/[ \frac{x^{-2+1}}{-2+1} ]^{10}_1$

$w =3[ \frac{x^{-1}}{-1} ]^{10}_1$

$w =3[ -\frac{1}{x} ]^{10}_1$

$w =3[ -\frac{1}{10} -(-\frac{1}{1})]$

$w =3[ -\frac{1}{10}+\frac{10}{10})]$

$w =3[\frac{9}{10}]$

$w=2.70$

Therefore, the work done by the object is $2.70J$ .
