First re-write the problem and distribute the negative... 7x+3 -2x-1.
Then combine like terms as so... 7x -2x= 5x and 3 - 1= 2.
Re-write once more... 5x+2.

A cylinder has a diameter of 24 inches. If its height is half its radlus, what is the volume of the cylinder in cubic Inches?
ella [17]

Answer:

about 2714.34 in^3

Step-by-step explanation:

24/2=12--radius

12/2=6--height

formula is V=(pi)(r^2)(h)

r is for radius and h is for height

V=(pi)(12*12)(6)

V=(pi)(144)(6)

V=(pi)(864)

V= about 2714.34 in^3

What is the intial value and rate of change in this graph. please explain step by step!!!!!
WARRIOR [948]

The initial value of the graph is where x = 0. Thus, in this case, the initial value is 12.


The rate of change of the graph is essentially the slope of the graph. In this case, we can use the slope formula:

\dfrac{y_2 - y_1}{x_2 - x_1}

  • (x_1, y_1) and (x_2, y_2) are points on the graph

Let's use two points from the chart to find the slope:

m = \dfrac{30 - 21}{2 - 1} = 9


In this case, the rate of change of the graph is 9.

Find the circumference
tia_tia [17]

Answer:

6.25\pi

Step-by-step explanation:

A circumference of a circle can be determined by this: 2*pi*r

We're given the diameter. Divide that by 2 to get the radius.

6.45/2 = 3.225

Now multiply that by 2*pi. That gives us 2 * 3.14 * 3.225 = 20.253.

This could've also been done easier by doing pi*d where d is the diameter and you give the answer by multiplying them both. Also works, but the above formula is just key to many things and can also be used to derive the simpler one. Hope it helps! :)
