Apply the appropriate mathematical operation to solve this fulcrum problem.
ale4655 [162]
<h2>Hello!</h2>

The answer is:

The second distance (distance_{2}) is equal to 7.5 feet.

<h2>Why?</h2>

Since we are given two forces acting at distance, torque will be created. We are given two forces and one distance, so, to calculate the other distance required to balance the system (solve this fulcrum problem), we need to write the following equation:

Torque_{1}=Torque_{2}

Where,

Torque=F*Distance

We are given,

Force_{1}=Weight_{1}=150lb\\Force_{2}=Weight_{2}=30lb\\distance_{1}=15ft\\

So, substituting and calculating, we have:

Torque_{1}=Torque_{2}

Weight_{1}*distance_{1}=Weight_{2}*distance_{2}

150lb*15ft=300lb*distance_{2}

distance_{2}=\frac{150lb*15ft}{300lb}=7.5ft

Hence, the second distance (distance_{2}) is equal to 7.5 feet.

It's a logical solution since the second force is twice the first force and it means that the second distance must be equal to half the first distance in order to maintain the equilibrium condition.

Have a nice day!

Having problems with this, please help.<br>And don’t know where to start.
rodikova [14]

Answer:

Use the pythagorean theorem to solve the equations. If you aren't solving for c, manipulate the equation to solve for whichever side you are solving for.

4)_Slope = 4; contains (-5, - 13)<br> I need help please
castortr0y [4]

Answer:

The equation of the line with slope = 4 and point (-5, -13)

will be:

  • y=4x+7

Step-by-step explanation:

Given

  • slope = m = 4
  • point = (-5, -13)

As the point-slope form of the equation of line is

y-y_1=m\left(x-x_1\right)

where m is the slope.

substituting the values m = 4 and the point (-5, -13)

y-y_1=m\left(x-x_1\right)

y-\left(-13\right)=4\left(x-\left(-5\right)\right)

y+13=4\left(x+5\right)

subtract 13 from both sides

y+13-13=4\left(x+5\right)-13

y=4x+7

Therefore, the equation of the line with slope = 4 and point (-5, -13)

will be:

y=4x+7
