A50-foot tree casts a shadow 9 feet long. the sine of the angle between the
ground and the line that connects the tip of the shadow to the top of the tree
is approximately

answer:

the length of the shadow is bout 9*20=180

step-by-step explanation:

  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.

the answer is d
