Answer:

19

Step-by-step explanation:

the formular for calculating the perimeter of a semi circle is πr

from the figure, r= 12/2= 6

perimeter= 3.142×6 = 18.852

perimeter = 19 approximately

Apply the appropriate mathematical operation to solve this fulcrum problem.

<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!

Richard Saltwood’s car averages 620 miles on its 20-gallon tank of gas. If Richard runs out of gas and a mechanic comes to his r
grandymaker [24]
Well first you have to divide 620/20 which is 31. So his car goes 31 miles per gallon so you have 2 gallons and .25 of a gallon. So first off 2*31=62 miles then the 1/4 or .25. Multiply the 31 by .25 which is 7.75 now add 62 and 7.75 and you get how far his car can go. 

62+7.75=69.75 miles

EXAMPLE 10 Show that there is a root of the equation 2x3 − 4x2 + 3x − 2 = 0 between 1 and 2. SOLUTION Let f(x) = 2x3 − 4x2 + 3x

Answer: c = 1.2

Step-by-step explanation:

First, it is needed to determined the values for x = 1 and x = 2:

f(1) = -1, f(2)=4

The sign change within the interval is the most sound evidence of the root existence. According to the Intermediate Value Theorem, there is a number c such that f(c) = 0. Another finding is that c is closer to 1 than to 2.

c = a + \frac{b-a}{f(b)-f(a)}\cdot[f(c)-f(a)]

c = 1 + \frac{2-1}{4-(-1)}\cdot[0-(-1)] \\c = 1.2
