Answer: 2900185 Joules

Step-by-step explanation:

Force used to tow the car is 1600N

Angle(α)= 25

Displacement = 2km

Recall that 1km= 1000m

Therefore 2km= 2000m

Workdone= FdCos α

W= 1600 * 2000 * cos 25

W=2900184.919

W= 2900185 Nm(when approximated to the nearest integer)

Since 1J = 1Nm

Work done = 2900185 J

After studying the diagram shown, Michael makes the following conclusions:
inn [45]

Answer:

Therefore, Michael concludes option C)

C)(DA)^{2}=(DG)^{2}+(AG)^{2}

Step-by-step explanation:

Given:

1. DG = 3 and the area of square DEFG is 9.

2. AG = 4 and the area of square GHIA is 16.

3. DA = 5 and the area of square ABCD is 25.

So we have,

(DG)^{2}=3^{2}=9\\ \\(AG)^{2}=4^{2}=16\\\\(DA)^{2}=5^{2}=25\\

Now Add DG² and AG² we get

(DG)^{2}+(AG)^{2}=9+16=25=(DA)^{2}

Which is also called as  Pythagoras theorem i.e

(\textrm{Hypotenuse})^{2} = (\textrm{Shorter leg})^{2}+(\textrm{Longer leg})^{2}

Therefore, Michael concludes option C)

C)(DA)^{2}=(DG)^{2}+(AG)^{2}
