An aspiring engineer wants to build a timer by taking a glass cylinder, filling it with water, suspending it in the air, and cutting a small hole in the bottom. he notes that at 1 p. m., the cylinder is 80% full, and at 2 p. m., it is 65% full. draw a graph expressing this and interpret the meaning of the y-intercept.

y axis denotes the level of water in cylinder

x axis denotes the time

Step-by-step explanation:

Given : At 1 p.m. cylinder is 80% full i.e. 0.80.

           At 2 p.m. cylinder is 65% full i.e. 0.65.

Solution :

time(x) :        1                    2

level (y) :      0.80            0.65

Using these points we can plot the graph (refer the attached figure)

In the figure y axis denotes the level of water in cylinder

x axis denotes the time

We can also find the equation of the graph by using two point slope form :

 ---a

Where m is the slope

Since  

Thus  slope (m) =

Now putting values in equation a

Thus the required equation of the situation or the graph is

THE GRAPH IS ATTACHED AND Y INTERCEPT DENOTES THE LEVEL OF WATER

the correct answers i think are b. and d.

give me brainliest if it is correct!

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
