Answer:
12 ft
Step-by-step explanation:
The ladder forms a right triangle with the building and the ground, since the ground is perpendicular to the building
Therefore, we can use the Pythagorean theorem:
c2 = a2 + b2
From the information in the problem, c is 20 ft, b is 16 ft, and a is what we solve for:
(20 ft)2 = a2 + (16 ft)2
a = √((20 ft)2 - (16 ft)2) = 12 ft
Answer:
2nd option
Step-by-step explanation:
It's direct because it's equation is y = -1/2x
That means it passes through the point (0, 0), making it an example of direct variation.
Answer:
I think it's around 31
Step-by-step explanation:
Just flip the slope fraction, and make it negative
6 /4 negative reciprocal is -4 / 6
Then replace the slope with the new slope.
y = -4/6 x + 4
