Answer:
Step-by-step explanation:ok so if you want too do the the root symbl on what
Given:
D=165 feet and the frequency of the motion is 1.6 revolutions per minute.
Solution:
The radius is half of the diameter.
The radius of the wheel is 82.5 feet.

As we know: 
Substitute the value of T in the above formula.

If the center of the wheel is at the origin then for
the rest position is
.
This can be written as:
The actual height of the rider from the ground is:

The required equation is
.
Answer:
B.
Step-by-step explanation:
We have been given a rational expression
and we are asked to simplify our rational expression.
We can see that our denominators are not equal. Since the two denominators do not share any common factors, the common denominator is simply the product of these two denominators.
To keep the value of expression same we will multiply the same quantity with numerators and denominators.
Now let us simplify our expression using FOIL.
Now we have same denominators, so we can add our numerators.
Now let us combine like terms.
Therefore, the simplest form of our given rational expression will be
and option B is the correct choice.
Answer:
22 units

Final Calculations:
- perimeter = 2 x (3+8)
- perimeter = 22
Bag weight 1.8 kg
Golf ball weight: 45g
1 kg = 1000g
Total bag weight in grams = 1.8 x 1000 = 1800g
total bag weight / golf ball weight = total balls in bag
1800 / 45 = 40
Total balls in bag = 40.
