a counterclockwise rotation about the origin of 90°

The coordinates of P(3, 3), Q(5, 3), R(5, 7)

The coordinates of P'(- 3, 3 ), Q'(- 3, 5), R'(- 7, 5)

Note that the y-coordinate of the image is the negative of the original, while the x-coordinate of the original becomes the y-coordinate of the image

The rotation which does this is a counterclockwise rotation about the origin of 90°

a point (x, y ) → (- y, x )

Selim is ordering concrete spheres to place as barriers in the city park. The spheres cost $2 per square foot, and Selim can spe

vlada-n [284]

Answer:

1.78 feet.

Step-by-step explanation:

If they cost $20 each and its $2 per square foot, the area of the spheres

is 20 / 2 = 10 ft^2.

Area of sphere = 4 π r^2 = 10 (where r = the radius)

---> r^2 = 10 / 4π

= 0.796

---> r = 0.892 ft

So the diameter = 2 * r

= 1.78 feet to nearest hundredth.

Which graph represents the function f(x)=-|x|-2 ?

Elden [556K]

Answer:

The graph of given function is shown below.

Step-by-step explanation:

The absolute parent function is g(x)=|x|. The graph of parent function is a V-shape d and vertex of the function is origin.

The given function is

$f(x)=-|x|-2$ .... (1)

The vertex from of an absolute function is

$f(x)=a|x-h|+k$ .... (2)

where, a is a constant and (h,k) is vertex of the function.

From (1) and (2) we get

$a=-1,h=0,k=-2$

The value of a is -1. The value of a is negative it means the graph of parent function reflect across x-axis.

The vertex of the function is (0,-2). It means the graph of parent function shifts 2 units down.

The graph of given function is shown below.
