Answers:

Answer for row one:     1

Answer for row two:     11

Answer for row three:   16

Answer for row four:     36

=========================================

Work Shown:

Whatever the x value is, we multiply by 5 and subtract off 14 to get the corresponding y value. This is following the order of operations PEMDAS

------------

If x = 3, then

y = 5*x - 14

y = 5*3 - 14  ..... note how x is replaced with 3

y = 15 - 14

y = 1

This means that when x = 3, the y value is y = 1.

So 1 goes in the box in the first row.

---------------

Repeat for x = 5

y = 5*x - 14

y = 5*5 - 14

y = 25 - 14

y = 11

We have 11 as the second answer.

--------------

Repeat for x = 6

y = 5*x - 14

y = 5*6 - 14

y = 30 - 14

y = 16

The third answer is 16.

--------------

Repeat for x = 10

y = 5*x - 14

y = 5*10 - 14

y = 50 - 14

y = 36

The last answer is 36.

melisa1 [442]

Answer:

6509.84 ft to the nearest hundredth.

Step-by-step explanation:

We have a right triangle in which the opposite side is 1479 ft and we need to find the adjacent side:

Tan 12.8 = opposite / adjacent side

tan 12.8 = 1479/ x

x = 1479/tan 12.8

= 6509.84 ft.
