Jorge is setting up his tent. He is using two nylon ropes to pull the tent taut and stabilize it at each end. If the tent is 5 feet tall, and Jorge stakes the ropes into the ground 3 feet from the tent, what is the total length of nylon rope he will use, to the nearest tenth of a foot? Show all of your work.

Step-by-step explanation:

The total length of the nylon rope, the height of the tent, the ground distance from the stake to the tent, forms a right angle triangle.

We can apply the Pythagoras Theorem to find the total length of nylon rope Jorge will use.

According to the Pythagoras Theorem, the sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse.

Note that the height of the tent and the ground distance to the stake formed the legs, while the length of the nylon rope forms the hypotenuse.

This implies that:

Round to the nearest tenth

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
