Which explanation can be used to informally derive the formula for the volume of a cylinder? a cylinder is similar to a triangul
romanna [79]
The correct is one is; A cylinder is like a stack of circles. The volume of the cylinder would be the area of the circle multiplied by the height of the cylinder. The height of the cylinder represents how many circles are in the stack. Therefore, we get the formula πr²h, where πr² represents the area of the circle and h the height of the circle.

Find the average rate of change of the function on the interval specified.
Gnom [1K]

The average rate of change of the function will be 63.

The average rate of change of the function is used to find the slope of the graphed function which can be calculated by the change in y value divided by the change in x value.

The average rate of change of function f(x) in the interval [a,b] can be calculated as avearge rate of change= (f(b)- f(a))/(b-a)

Here given function is g(x) = 7x³-4

which is defined in the interval [-3,3].

So using the defination of the average rate of change, The average rate of change= (g(3)-g(-3))/(3-(-3))

= {(7(3³)-4)-(7*(-3)³-4)}/(3-(-3))

= {(189-4)-(-189-4)}/(3+3)

= (185-(-193))/6

= (185+193)/6

= 378/6

= 63

Therefore the average rate of change of the function will be 63.

X + 3y = -9<br> 5x + 3y = 3
kap26 [50]

Answer:

X=3,y=-4

Step-by-step explanation:

The only change is x so you could figure it out that way or do this:

4x=12 by subtracting the secound equation by the first one (since both y's are being multiplied by the same thing you can do this to cancel them out while making one equation). and than figure out x=3 from there you input that into eithger equation to figure out y. Hope this helped!
