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.

The interpretation of the point of intersection of the curves is (c) they give a solution to the equation 5x - x^2 = 3x - 0.5x^2

<h3>How to interpret the points of intersection?</h3>

The graph of the two functions alongside their equations are the given parameters of this question

The functions are given as:

f(x) = 5x - x^2

g(x) = 3x - 0.5x^2

When the graphs of two curves or lines intersect on a coordinate plane, it means that the point of intersection represents where the graphs have equal value

In this case, it represents

f(x) = g(x)

Substitute the known values in the above equation

5x - x^2 = 3x - 0.5x^2

So, the interpretation of the point of intersection of the curves is (c) they give a solution to the equation 5x - x^2 = 3x - 0.5x^2

A triangle with vertices at A(0, 0), B(0, 4), and C(6, 0) is dilated to yield a triangle with vertices at A′(0, 0), B′(0, 10), a
sineoko [7]
ANSWER

The scale factor is
2.5

EXPLANATION

The given triangle has vertices,

A(0,0),B(0,4),\:and\:C(6, 0).

The vertices of the image triangle is,

A'(0,0),B'(0,10),\:and\:C'(15, 0).

The scale factor is given by

k = \frac{image \: length}{object \: length}

So we can use any of the corresponding sides to determine the scale factor,

k = \frac{|A'B'|}{ |AB|}

k = \frac{ |10 - 0| }{ |4 - 0|}

k = \frac{ |10| }{ |4 |} = \frac{10}{4} = 2.5

Or

k = \frac{|A'C'|}{ |AC|}

k = \frac{ |15 - 0| }{ |6 - 0|}

k = \frac{ |15| }{ |6|} = \frac{15}{6} = 2.5


Or

k=\frac{|B'C'|}{|BC|}

k = \frac{\sqrt{(15 - 0)^2+(0-10)^2 }}{\sqrt{(6 - 0)^2+(0-4)^2}}

k = \frac{ 5\sqrt{13}}{2\sqrt{13}} = \frac{5}{2} = 2.5

The correct answer is C
