The tallest student in the Freshman class is 2.1 m high. When Mr. Langston stands far away from the student, his line of sight to the top of the student's head forms an angle of elevation of 18 degrees with the ground. What is the horizontal distance between the tall student and Mr. Langston? Round to the nearest meter.

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
