F(x)<0 over and what other interval? A. (-2.4,-1.1)

B. (-3,-1.1)

C. (-1.1,2)

D. (-1.1,0.9)

it is c, trust i got your back lol

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

part a: 1.08

part b: 27.59
