In order to compute the markup, compute the percentage like this:
The markup is then $12,32.
The selling price is the sum of the cost and the markup:
The markup is then $12,32.
The selling price is the sum of the cost and the markup:
A squirrel runs at a steady rate of 0.51 m/s in a circular path around a tree. If the squirrel's centripetal acceleration is 0.4
3 m/s 2 , what is the radius of the circle?
0.60 m 1.2 m 0.36 m 0.84 m
0.60 m 1.2 m 0.36 m 0.84 m

Answer:
Radius of the circle, r = 0.60 meters.
Step-by-step explanation:
It is given that,
Speed of the squirrel, v = 0.51 m/s
The centripetal acceleration of the squirrel,
We need to find the radius of the circle. The centripetal acceleration is given by :
r = 0.60 m
So, the radius of the circle is 0.60 meters. Hence, this is the required solution.

Step-by-step explanation:
Using an algebraic method like elimination or substitution would take a lot of steps which could lead to mistake the calculations. In this case, I decided to use the Gaussian elimination. We can express the system in matrix form as follows:
To begin the calculations, we write the system in augmented matrix form and use the Gaussian elimination:
By applying the Gaussian elimination, the final matrix is the following:
In order to verify the results, it´s enough to substitute the calculated values in the original equations to see if the equalities are correct. Here you can see the verification for all of the equations:
