A Farmer Leans a 12 ft Ladder Against A Barn. The Base of the Ladder Is 6ft From The Barn.l To The Nearest Foot, How High on the

vlada-n [284]

Answer:

10 ft to nearest foot.

Step-by-step explanation:

We use the Pythagoras theorem:

12^2 = 6^2 + h^2 where h is the height on the barn

h^2 = 12^2 - 6^2

h^2 = 144 - 36 = 102

h= √108 = 10.39

Option C: $\frac{4}{5}$ is the slope of the line

Explanation:

The line passes through the points $(3,-1)$ and $(-2,-5)$

We need to find the slope of the line.

The slope can be determined using the formula,

$m=\frac{y_2-y_1}{x_2-x_1}$

Where the coordinates $(x_1,y_1)$ and $(x_2,y_2)$ are $(3,-1)$ and $(-2,-5)$

Let us substitute the points in the formula

Thus, we have,

$m=\frac{-5-(-1)}{-2-3}$

Simplifying, we get,

$m=\frac{-5+1}{-2-3}$

Adding the numerator and denominator, we have,

$m=\frac{-4}{-5}$

Cancelling the negative terms, we get,

$m=\frac{4}{5}$

Thus, the slope of the line is $m=\frac{4}{5}$

Therefore, Option C is the correct answer.
