Answer:

$\displaystyle 415,5\:units^2 ≈ A$

Step-by-step explanation:

In the circumference, 27 represents the diameter, and the radius is <em>half</em><em> </em>the diameter, so take half of it to get 11,5. Then use it in the area formula:

$\displaystyle πr^2 \\ \\ π11,5^2 = 132,25π ≈ 415,4756284 ≈ 415,5$

I am joyous to assist you anytime.

Check the picture below.

well, g(x) + 1 is simply a vertical shift upwards of 1 unit, if the vertex before that had a y-coordinate of 4, then later on became 4+1 or 5, so the new vertex is simply (3 , 5).

Answer: 7

Step-by-step explanation:

$(4+5)-2$

You can either remove brackets and just do a little addition and subtraction.

$4+5-2$

$9-2\\7$

So the answer is 7.

Or just finish things inside the brackets first.

$(4+5)-2\\9-2\\7$

So the answer is 7.

If P=(2,-1),find the image of P under the following rotation. 180 degrees counterclockwise about the origin

vichka [17]

Answer:

(-2, 1)

Step-by-step explanation:

Rotating a point 180° about the origin in either direction is equivalent to reflecting it across the origin. The effect is to negate both coordinates.

(x, y) ⇒ (-x, -y) . . . . . rotation 180°

(2, -1) ⇒ (-2, 1) . . . . . P' rotated 180° from P

The coordinates of the rotated point are (-2, 1).
