What is the image of the point (-8,3)(−8,3) after a rotation of 270^{\circ}270
∘
counterclockwise about the origin?

Answers

Answer 1

Given:

The point is (-8,3).

To find:

The image of the given point after a rotation of 270 degrees counterclockwise about the origin.

Solution:

If a point is rotated 270 degrees counterclockwise about the origin, then the rule of rotation is:

[tex](x,y)\to (y,-x)[/tex]

Using this rule, we get

[tex](-8,3)\to (3,-(-8))[/tex]

[tex](-8,3)\to (3,8)[/tex]

Therefore, the  image of the given point after a rotation of 270 degrees counterclockwise about the origin is (3,8).

Answers

Answer:  x = -15

Hope this helps :)

Answer:

x = -15

Step-by-step explanation:

[One step multiplication problem]

When solving a one-step multiplication problem the easiest thing to do would be to divide the 'answer' (in this case, 45) by the coefficient (in this case, -3). A negative number times a negative number is a positive number, so x would be a negative number. 45 divided by -3 is -15.

So, x = 15.

find the measure of the arc AC

Answers

i get mABC = 270°
Step-by-step explanation:
This is fairly straight forward once you the right angle symbol for the arc AC. Also realizing the 148° for mAB is not needed for this question. The 148° for mAB would be useful if you wanted to calculate arc mBC.
Remember there are 360° in a circle.
The arc mAC is 90°
The arc mABC is the rest of the circle. is the arc from A to B to C
arc ABC + arc AC is the full circle 360°
mABC + mAC = 360° mAC = 90°
mABC + 90° = 360° - 90° from both sides
mABC = 360° - 90°
mABC = 270°

Answer and Step-by-step explanation:

8. We want to solve for a of the trapezoid area formula.

A = [tex]\frac{h}{2} (a + b)[/tex]

First off, we need to multiply both sides by [tex]\frac{2}{h}[/tex] to cancel out the [tex]\frac{h}{2}[/tex].

[tex]\frac{2A}{h}[/tex] = a + b

Now, we need to subtract b from both sides.

[tex]\frac{2A - b}{h}[/tex] = a

We get the answer to be:

I. a = [tex]\frac{2A - b}{h}[/tex]

Two angles are complementary. The first angle is 2x degrees. The second angle is (3x +5) degrees. Determine the measure of each angle.

Draw the angles, write and equation and solve the measures of each angle.

HELP PLEASE

Answers

Answer:

70 and 110

Step-by-step explanation:

First angle -- 2x

Second angle -- 3x + 5

Therefore,

2x + 3x + 5 = 180

5x = 175

x = 35

Therefore, 2x -- 70

3x + 5 -------------110

I got 11,232,000, but I'm pretty sure that's wrong.

Answers

Answer:

3 letters can be arranged in 26*25*24 = 15600 ways

3 digits can be arranged in 10 * 9 * 8 = 720 ways

So the total number is 15600 * 720 = 11,232,000
