maria [59]

Answer:

<em>Answer: (second option) (-4,1)</em>

Step-by-step explanation:

<u>Transformations of Points and Shapes</u>

The image shows a trapezoid ABCD where point A has coordinates (-4,1).

The following transformations are performed:

Reflection over the y-axis: If a point (x,y) is reflected over the y-axis, it becomes (-x,y). Thus point A becomes A'=(4,1)

Reflection over the x-axis: If a point (x,y) is reflected over the x-axis, it becomes (x,-y). Thus point A' becomes A''=(4,-1)

Rotation 180°: If a point (x,y) is rotated 180°, it becomes (-x,-y). Thus point A'' becomes A'''=(-4,1)

Answer: (second option) (-4,1)

Ron is designing a new slide for the amusement park in town the slide makes an angle of 39 degrees with the ground.The top of th

Fynjy0 [20]

Answer:

The length of the slide he needs to make = AC = L = 14.3 ft

Step-by-step explanation:

From the Δ ABC

AC = Length of the slide = L

AB = 9 ft

$\theta = 39$ °

From Δ ABC

$\sin \theta = \frac{AB}{AC}$

Put all the value in the above formula

$\sin 39 = \frac{9}{L}$

$L = \frac{9}{0.629}$

L = AC = 14.3 ft

Therefore the length of the slide he needs to make = AC = L = 14.3 ft
