iris [78.8K]

Answer:

-10

Step-by-step explanation:

A slope's equation for 2 points on a coordinate plane is y² - y^1 ÷ x² - x^1

Note that the exponents aren't meaning powered, but just as a marking.

x1 is 2, x2 is 4, y1 is 150, y2 is 130

130-150 / 4-2 = -20/2, so -10

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 $(to the nearest tenth of a foot).\\Therefore, the lenght of the broken part of the tree to the nearest tenth of a foot is 14.3 feet.$
