nasty-shy [4]

Answer:

the answer is \sqrt{5\\} , and - \sqrt{5\\} which is C.

Step-by-step explanation:

well I got that answer by doing this

we have x^{2}= 5

For x^{2}= f (a) the solutions are x = \sqrt{f(a)\\} , - \sqrt{f(a)\\}

so in this case the solutions are \sqrt{5\\}, and - \sqrt{5\\}

An 11-ft ladder leans against the side of a house. The bottom of the ladder is 9-ft from the side of the house. How high is the
bulgar [2K]

Answer:

6.3 ft.

Step-by-step explanation:

This requires the pythagorean theorem: a^2+b^2=c^2 where "a" and "b" are legs and c is the hypotenuse(longest side of the triangle which is opposite to the 90 degree angle.) If we fill the equation where c is the ladder length(11) and "a" is the distance from the house(), and "b" is the height, 9^2+b^2=11^2 or 81+b^2=121. This is equivalent to b^2=40. b=6.3 when rounded to the nearest tenth.
