5) Placido pulls a rope attached to a wagon through a pulley at a rate of q m/s. With dimension as in Figure 5:
Damm [24]

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

(a) \ \mathrm{The \ speed \ of \ the \ wagon} , \ \dfrac{dx}{dt} = q -\dfrac{x}{\sqrt{x^2+ 5.76}}

(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 = \mathbf{\dfrac{dx}{dt}}

The speed of the rope, q = \mathbf{\dfrac{dr}{dt}}

By chain rule, we have;

\dfrac{dr}{dt} = \mathbf{\dfrac{dr}{dx} + \dfrac{dx}{dt}}

\dfrac{dr}{dx} = \dfrac{x}{\sqrt{x^2+ 5.76}}

Therefore;

\dfrac{dr}{dt} = q =\dfrac{x}{\sqrt{x^2+ 5.76}}+ \dfrac{dx}{dt}

\mathrm{The \ speed \ of \ the \ wagon} , \ \dfrac{dx}{dt} = \underline{ q -\dfrac{x}{\sqrt{x^2+ 5.76}}}

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

\dfrac{dx}{dt} = 0.5 -\dfrac{0.6}{\sqrt{0.6^2+ 5.76}} =\sqrt{\dfrac{1}{17} } \approx 0.243

The speed of the wagon when <em>x </em>= 0.6 and q = 0.5 m/s, \dfrac{dx}{dt} ≈ <u>0.243 m/s</u>

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

marysya [2.9K]

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)
