Answer:
the correct answer is Trinomial
Answer:
- The first factor is itself the sum of two terms
- The solution is the product of two factors
Step-by-step explanation:
The math symbols of the expression include parentheses, a plus sign, and a multiplication symbol. The order of operations tells you to do the "plus" operation inside parentheses first. The numbers involved in a "plus" operation, or sum, are called "terms." The result is their sum.
Then the second operation in the order of operations is to do the multiplication of the sum on the left of the multiplication symbol by the number to the right of the multiplication symbol. The numbers involved in multiplication are called "factors". The result of multiplication is called a "product."
Matching up this vocabulary with what you see, you realize ...
- the first factor is the sum of two terms
- the end result of evaluating the expression is the product of two factors
4768 x 1551 is 7395168
7395168 divided by 10.2 is 725016.5 (rounded to the nearest tenths)
Consider the point P where the gears meet. When the smaller gear rotates clockwise, the larger one will rotate counterclockwise.
Through one rotation of the smaller gear, P will have traveled the circumference of the smaller gear, which is
in.
At the same time, a point P' on the larger gear traverses the same distance along the larger gear's circumference. This point traces out an arc that is subtended by some angle
. The arc is as long as the smaller gear's circumference.
The measure of a circle's interior angle subtended by an arc is proportional to a complete revolution, i.e. an angular displacement of
radians:

For part 2, we apply the same reasoning to the larger gear. In one full rotation of the larger gear, the point P' traverses the circumference
in, and so does the point P on the smaller gear.

A full rotation is 360 degrees, so the smaller gear would have rotated
times.
