How to do this question plz

Maximum number of cups completely filled

= 19500 ÷210

= 92.857 (5 s.f.)

Since there is not enough water to fill the 93rd cup, at most 92 cups can be filled completely from the water container.

Step-by-step explanation:

1L= 1000mL

① Ensure all the units of volume are the same. Here, I am converting all the units into mL.

Amount of water in the water container

= 19.5 L

= 19.5(1000) mL

= 19500 mL

② Find the number of cups that can be filled.

Since 1 cup has the volume of 210 mL, let's find the number of sets of 210 mL there are in 19500 mL.

19500 ÷210

= 92.857

= 92 (maximum possible number of cups)

Although 92.857 cups would be theoretically be rounded up to 93 cups, we have to write 92 cups as the 93rd cup will not be completely filled.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
