This is a question that will require Pythagoras' theorem as you want to find the length of a diagonal of a triangle and are given the measurements of two sides. I have attached a picture of how to solve this problem.
To the nearest 10th of a foot, the answer is 77.6ft
Answer:
the 2nd and 4th expressions are the appropriate ones.
Step-by-step explanation:
both result in '0' which means that kiana is on the ground floor of the building at the end.
Answer:

Step-by-step explanation:
Coordinates are (0,6) and (1,3)
Slope = 
Slope = 
Slope = -3
<u><em>Now, Finding b</em></u>
Taking any Point
Point = (x,y) = (0,6)
So, x = 0, y = 6
<em>Putting in slope-intercept form to find b</em>

=> 6 = (-3)(0)+b
=> b = 6
<u><em>Now Putting slope and b in the formula to get the required slope-intercept form.</em></u>

=> 
Personally I think the answer would be c. Cross multiplication
