9514 1404 393

Answer:

  25 (ft/s)

Step-by-step explanation:

The "rate of change" is taken to mean the "rise" divided by the "run". Here, adjacent points differ in their y-value by 25 ft and their x-value by 1 second.

The rate of change is ...

  rise/run = (25 ft)/(1 second) = 25 ft/second

Usually, we're just interested in the numerical value: 25.

_____

<em>Additional comment</em>

The graph is mis-labeled. It is not showing "rate of ascent." It is showing height as a function of time. The "rate of ascent" is the <em>slope</em> of the line on the graph, not its <em>value</em>.

In the same way, the x<span>-axis is also the line "y = 0". Then, algebraically, an </span>x-intercept is a point on the graph where y is zero, and. a y-intercept<span> is a point on the graph where </span>x<span> is zero.
Honestly I didn't get it either but I hope this helped ^ ^</span>

Barb is going to cover a rectangle area 8 feet by 10 feet with rectangle paving blocks that are 4 inches by 8 inches by 2 inches
soldier1979 [14.2K]

Step-by-step explanation:

First, transform 8 feet and 10 feet into inches so we can work with the same measurements

8 * 12 = 96 in

10 * 12 = 120 in

Next find the patio rectangle area.

96 * 120 = 11520 in^2

Now find the paving block area

4 * 8 = 32 in^2

Now, find out how many paving blocks will go into the patio rectangle area.

11520 / 32 = 360

The minimum number is 360 paving blocks

Alexandria cuts out the net shown and folds it into a number cube. Three faces meet at each corner of the cube. What is the larg
ZanzabumX [31]

The largest sum of three numbers that meet at a corner is 15

<h3>How to determine the largest sum?</h3>

The number cube that completes the question is added as an attachment

The largest number in the number cube is 6.

On the number cube, the next largest numbers share the same corner with the number 6

So, the largest set of numbers on the cube are 6, 5, 4

Add the numbers:

Sum = 6 + 5 + 4

Evaluate

Sum = 15

Hence, the largest sum of three numbers that meet at a corner is 15
