Aladder is needed to reach the top of a 60 foot building. if the base of the ladder is to be placed 11 feet from the building how long must the ladder be

Hello!

If the ladder is placed 11 feet from the building, it will be slanted. The building, ground, and ladder will create a right triangle. We can use the Pythagorean Theorem to solve for the ladder (the hypotenuse). We will use a²+b²=c², where a and b are the building and ground, while c is the ladder.

60²+11²=c²

3600+121=√3721

√3721=61

Therefore, our ladder must be 61 feet long.

I hope this helps!

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
