The formula for the speed of the wagon can be found by using Pythagoras theorem, and chain rule of differentiation.

(b) When <em>x </em>= 0.6 and q = 0.5 m/s, the speed of the wagon is approximately <u>0.243 m/s</u>.
Reasons:
(a) The distance from the cart to the pulley, <em>r</em> is given by Pythagoras's
theorem as follows;
r = √((3 - 0.6)² + x²) = √(2.4² + x²)
The speed of the wagon = 
The speed of the rope, q = 
By chain rule, we have;


Therefore;


(b) The speed of the wagon when <em>x</em> = 0.6 if q = 0.5 m/s is given as follows;

The speed of the wagon when <em>x </em>= 0.6 and q = 0.5 m/s,
≈ <u>0.243 m/s</u>

Answer:
Rest of the team= 20 goals
Step-by-step explanation:
Giving the following information:
Joshua= (2/7)
His team scored 28 goals this past season.
<u>First, we determine hoy many goals Joshua score:</u>
Joshua= (2/7)*28
Joshua= 8 goals
<u>Now, the rest of the team:</u>
Rest of the team= 28 - 8
Rest of the team= 20 goals
Answer:
6
Step-by-step explanation:
So, 12 dimes is 120 cents. 120 cents is $1.20. You said he had 18 coins, and 12 dimes takes away 12 coins. So the only number left is 6. (I think)
