Rectangle PQRS is rotated 90° counterclockwise about the origin.

Mathematics
1 answer:
laila [671]3 years ago
6 0

Answer:

Object point Q (x,y) ------------- image point Q'( -y,x)

Step-by-step explanation:

When a point A (x,y) is rotated 90 degrees counterclockwise about the origin the resulting image of the point is A'(-y,x)

This means first you alternate the positions of x and y coordinates then add a negative sign on the now new y coordinate.

Example a point B(2,3) rotated 90° counterclockwise about the origin will form an image B'(-3,2)

So if point Q (x,y) ------------- image Q'( -y,x)

Substitute real values for (x,y) coordinates to get correct answer.

GEOMETRY HELP! <br><br> This is my last question and I don’t know what the answer is! Please help!
Angelina_Jolie [31]

Temporarily subdivide the given area into two parts: a large rectangle and a parallelogram. Find the areas of these two shapes separately and then combine them for the total area of the figure.

By counting squares on the graph, we see that the longest side of the rectangle is the hypotenuse of a triangle whose legs are 8 and 2. Applying the Pyth. Thm., we find that this length is √(8^2+2^2), or √68. Similarly, we find the the width of this rectangle is √(17). Thus, the area of the rectangle is √(17*68), or 34 square units.

This leaves the area of the parallelogram to be found. The length of one of the longer sides of the parallelogram is 6 and the width of the parallelogram is 1. Thus, the area of the parallelogram is A = 6(1) = 6 square units.

The total area of the given figure is then 34+6, or 40, square units.

How is the standard form of a linear equation similar to and different from the slope-intercept form?
natima [27]
<span>in standard form the equation has to be changed from slope-intercept form to standard. bt first you have to find the slope and then change the equation to standard form. 
the slope intercet form is y=mx+b using y-k= m(x-h)
and after, change the equation to ax+by+c</span>
