Answer: y=-8/10x+29

Step-by-step explanation:

1. choose 2 points on form the chart

(10,21)(20,13)

2. y2-y1/x2-x1

13-21/30-10=-8/10

3. y-y1=m(x-x1)

y-21=-8/10(x-10)

4. multiply

y-21=-8/10(x-10)
y-21=-8/10x+8

5. you need to isolate the variable so..

y-21=-8/10x+8
+21 +21

Bas_tet [7]

Answer:

14.3 feet.

14.3 feet

Step-by-step explanation:

The problem forms a right triangle in which:

The Vertical Leg of the Right Triangle = 3 feet

The Horizontal Leg of the Right Triangle =14 feet

We are to determine the length of the broken part of the tree. This is the Hypotenuse of the Right Triangle,

Using Pythagoras Theorem

$Hypotenuse^2=Opposite^2+Adjacent^2\\Hypotenuse^2=14^2+3^2\\Hypotenuse^2=205\\Hypotenuse=\sqrt{205}\\Hypotenuse=14.32\\ \approx 14.3 feet $(to the nearest tenth of a foot).\\Therefore, the lenght of the broken part of the tree to the nearest tenth of a foot is 14.3 feet.$
