The statement A is true
This is because the coordinate intersection would be, naturally, when x = 2 and y = 4

Answer:
The hiker's elevation after 145 minutes will be 1958 meters.
Step-by-step explanation:
The equation of the trend line of the scatter plot showing a hiker's elevation is y = 8.77x + 686 .......... (1), where x is in minutes (say) and y is in meters (say).
Now, we have to predict the hiker's elevation after 145 minutes.
So, from equation (1) we get, y = 8.77 × 145 + 686 = 1957.65 ≈ 1958 meters. (Answer)
Depending on the field over which you're factoring, you may also write the last factor as
Answer:
Base at the top should be the same length, thus 20ft.
right triangle thus 90 degrees angle.
180 - 90 - 40 = 50
20ft/sin50 = Height/sin40
Height of the traffic light = 16.78
16.78 + the height of Andrew eyes ( 5ft) = 21.78
