Answer:

Therefore the volume of the cylinder=\pi(2x^3-5x^2-24x+63)  cubic units

Step-by-step explanation:

Given height of a cylinder is (h) =2x+7

and radius  (r)= x-3

Volume of the cylinder = \pi r^2 h

                                  =\pi (x-3)^2(2x+7)

                                  =\pi (x^2-6x+9)(2x+7)

                                  =\pi (2x^3-12x^2+18x+7x^2-42x+63)

                                  =\pi(2x^3-5x^2-24x+63)  cubic units

Therefore the volume of the cylinder=\pi(2x^3-5x^2-24x+63)  cubic units

PLEASE HELP! - The scatterplot below shows the number of weeks that students have been in keyboarding class and the number of mi
Setler [38]

Solution: Which statement about the scatter plot is true?

The correct answer is option A. As the number of weeks in class increases, the number of keyboarding mistakes decreases.

Explanation: From the scatter plot, we clearly see there exists a negative linear  relationship between the number of weeks in class and the number of mistakes. And we know that if there exists a negative linear relationship between the two variables, then the values of two variables move in opposite direction. If the values of one variable goes up, the values of other variable go down. From the given scatter plot, we clearly see the number of mistakes goes down as the number of weeks in class increases. Therefore, the option A is correct

ELEN [110]

Answer:

Step-by-step explanation:

It is a good idea to try to save up money to buy large items or find 0% interest deals so

you are not paying interest. However, this is not always possible, especially when buying

a house or car. That is when it is important to understand how much interest you will be

charged on your loan.
