What is the rate of change from x = n to x = 2n?

puteri [66]

Answer:

$\dfrac{-8}{\pi}$

Step-by-step explanation:

The rate of change of the function f(x) from point $x_1$ to point $x_2$ can be calculated using formula

$\dfrac{f(x_2)-f(x_1)}{x_2-x_1}$

Given

$x_1=\pi\\ \\x_2=2\pi$

From the graph of the function

$f(x_1)=f(\pi)=4\\ \\f(x_2)=f(2\pi)=-4$

So, the rate of change is

$\dfrac{f(x_2)-f(x_1)}{x_2-x_1}=\dfrac{-4-4}{2\pi -\pi}=\dfrac{-8}{\pi}$

There are 480 soccer balls on a field. Every hour, half of the balls are put back into the locker room. Write an equation that c

Mrac [35]

Answer:

$y= 480-0.5x$

Step-by-step explanation:

Given data

Number of balls= 480

we are told that 50%(half) of the balls are put back every 1

let the number of hours be x

and let the remaining ball be y after x hours

Hence the expression is given as

$y= 480-0.5x$

Answer 35 and 36 fully with the way you did it not only answer!!

stellarik [79]

35a. We're asked to compute the ratio between the enlarged width and the original width. So we literally perform the operation:

$6.5\div 3.5 \approx 1.86$

35b. If the order is wrong the image would be shrunk instead of enlarged, with a ratio of $3.5\div 6.5$

36. We know that

$\dfrac{p}{q}=\dfrac{2}{3}$

Observe that

$\dfrac{6p}{2q}=\dfrac{6}{2}\cdot\dfrac{p}{q}=3\cdot\dfrac{p}{q}=3\cdot\dfrac{3}{2}=\dfrac{9}{2}$

A planter in the shape of a cube has a volume of 1,000 inches to the 3 power. Is the area of the base of the cube greater than o

GuDViN [60]

When the solid is a cube,its volume is equal to its side raised to the power of 3. The equation is written below:

V = s³

Since 1,000 is raised to the power of 3, then it means that the side length is equal to 1,000 inches. The base of the cube is also a square. Thus, its area is s². Note that there are 12 inches in 1 ft.

A = (1000 in * 1ft/12 in)² = 6,944.44 ft²

Thus, the area of the base is greater than 1 square foot.
