I'm assuming that the pitch of this roof is in fact its slope...

Slopes are basically tangents...

tan(x)=Opposite/Adjacent

-------

tan(x)=9/7

-------

This means that the answer is D), 9/7.

Answer:

D. \frac{9}{7}

Step-by-step explanation:

We have been given that the pitch of a roof that has a height of 9 ft and a horizontal run of 7.

We know that slope of a line represents the relation between rise over run. The run is the horizontal distance between to x-coordinates and rise is vertical distance between two y-coordinates.

\text{Slope}=\frac{\text{Rise}}{\text{Run}}  

\text{Slope}=\frac{9}{7}  

Therefore, the pitch of roof is \frac{9}{7} and option D is the correct choice.

Step-by-step explanation:

cos θ = 3 / AB

When θ = 28°:

cos 28° = 3 / AB

AB = 3 / cos 28°

AB ≈ 3.4

When AB = 5.2:

cos θ = 3 / 5.2

θ = cos⁻¹(3 / 5.2)

θ ≈ 54.8°

Answer:

Step-by-step explanation:

A ' = (-2, -3)

B ' = (0, -3)

C ' = (-1, 1)

=======================================================

Explanation:

To apply an x axis reflection, we simply change the sign of the y coordinate from positive to negative, or vice versa. The x coordinate stays as is.

Algebraically, the reflection rule used can be written as

Applying this rule to the three given points will mean....

Point A = (-2, 3) becomes A ' = (-2, -3)

Point B = (0, 3) becomes B ' = (0, -3)

Point C = (-1, -1) becomes C ' = (-1, 1)

The diagram is provided below.

Side note: Any points on the x axis will stay where they are. That isn't the case here, but its for any future problem where it may come up. This only applies to x axis reflections.
