Answer:
62.8 square inches
Step-by-step explanation:
we know that
To find out how many square inches of space the rolling pin comes in contact with after one complete roll, determine the lateral area of the rolling pin
The lateral area of a cylinder is given by the formula

we have

substitute

Answer:
C=252
Step-by-step explanation:
Given:
x^5y^5
(x+y)^10
Find the coefficient of x^5y^5
To get the coefficient of x^5y^5,
we will put r = 5, in the below given general term.
The general term is : nCr =x^ry^n-r
We get:
Coefficient is = 10C5
= 10!/5!*5!
= 252
The coefficient of x^5y^5 is 252
C. 252
First we take the two points (-7,5) and (-5,9).
Compute the slope:

Then the linear relation may be in the following form

Since the point (-7,5) is on the line, then

The relation is then

.
We check that the other point are on the above line:

W
e have then a linear relation.
