Triangle ABC is translated using the rule (x, y) → (x + 2, y - 2). Which of the following describes the horizontal and vertical

BlackZzzverrR [31]

X controls the left and right movement of the point, while y controls the up and down.

x + 2 means that the new position of the point would be two spaces towards the right of the original point.

y - 2 means that the new position of the point would be two spaces lower than the original point.

Therefore, translate right 2 units, down 2 units, should be your answer

Hope this helps

Find the area and show all work

____ [38]

Answer:

Area for rectangle = B*H

Area for triangle = B*H/2

total area = area of triangle + area of rectangle

A of rectangle = 17 * 22 = 374 cm²

Triangle height is not giving so we take 22-10 = 12 cm for the height so

A of triangle = 12*19/2 = 114 cm²

total A = 114 + 374 = 488 cm²

The height of the Eiffel Tower is 1050 feet. From the top, the angle of depression to a soccer ball on the ground is 20 degrees.

mihalych1998 [28]

Since the angle of depression from the Eiffel tower is congruent to the angle of elevation from the soccer ball, the angle of elevation from the soccer field is 20°

Now, we can use the trigonometric function tangent to find the distance from the soccer ball to the base of the Eiffel Tower:
 $tan( \alpha )= \frac{opposite.side}{adjacent.side}$
$tan(20)= \frac{1050}{a}$
$a= \frac{1050}{tan(20)}$
$a=2884.85$

We can conclude that the distance from the soccer ball to the base of the Eiffel Tower is 2884.85 feet.

What is the image point of (-2, 10) after the transformation rx-axis o D;?

Nastasia [14]

Answer:

This is a composition of transformations

First you have to rotate 180 and next you have to reflect over x axis.

The given point (-7,3) is on the second quadrant, after 180 rotation it will be on the fourth quadrant, (7,-3) Next you have to reflect that point over the x axis. So the final image of the point is on the first quadrant, (7,3).
