Find the coordinates of n after a 90 degrees clockwise rotation around the origin

Mathematics

Ket [755]3 years ago

Answer:

270 degrees

Step-by-step explanation:

If you want a positive number, you can say that the origin is 360 degrees. Then, being it's moving clockwise, subtract 90 degrees from 360 degrees. That will give you 270 degrees.

If you want a negative answer, you could simply say that the origin is 0 and subtract 90 from that giving you -90.

Odds are you should go with 270.

Solutions

To convert 2/14 into lowest terms you have to divide by the greatest common factor. The greatest common factor of 2 and 14 is 2.

2 ÷ 2 = 1
14 ÷ 2 = 7

1/7 is in lowest terms

219. 445 tickets are what you start off with. Multiply that by .6 (three-fifths) to find how many are sold. 226 were sold which means 219 are remaining unsold.

Which shapes can the composite figure be divided into to find the area

icang [17]

Given:

Composite figure

To find:

The shapes in the composite figure.

Solution:

The image splitted into three shapes.

Draw a line from top vertex to bottom vertex.
We get one triangle.
Similarly, draw another line adjacent to the previous line.
We get another triangle and rectangle.

Therefore a composite figure divided into a rectangle and two triangles.

A rectangle has a length that is 5 inches greater than its width, and its area is 104 square inches. The equation (x + 5)x = 104

Art [367]

Answer:

The answer is 8.

Step-by-step explanation:

We need to use the quadratic formula, that is ax2+bx+c=0

Where

$x=\frac{-b +/- \sqrt{b^{2}-4*a*c } }{2a}$

For the given equation x2+5x-104=0 we have

a=1, b=5, c= -104

If you solve that, we will have x=-13. x=8, two answers,

The first one, by being negative does not have physical sense (there are no negatives quantities when you measure the length of something)

So we use the anwser x=8
