An 11-ft ladder leans agalnst the side of a house. The bottom of the ladder Is 9 ft from the side of the house. How high Is the IS top of the ladder from the ground? If necessary, round your answer to the nearest tenth.

The top of the ladder is 6.3 feet high from the ground.

Step-by-step explanation:

The given question can be expressed by the three sides of a right angled triangle. Let the height of the top of the ladder from the ground be represented by h.

Thus, applying the Pythagoras theorem to determine h, we have;

= +

= +

121 =   + 81

= 121 - 81

    = 40

h =

  = 6.325

h = 6.325 feet

The top of the ladder is 6.3 feet high from the ground.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
