Answer:

-2700°


Step-by-step explanation:

  • 1 rotation is 360°, also
  • Counterclockwise angles are POSITIVE ANGLES & Clockwise angles are NEGATIVE ANGLES

7.5 rotations is 360*7.5=2700 degrees

and since it is clockwise, the angle is negative.


Hence, 7.5 rotations clockwise means -2700°

1 rotation equals 360 degrees.  1/2 of a rotation equals 360/2 = 180 degrees.  So, 7 times 360 degrees = 2520 degrees plus 180 degrees = 2700 degrees.

The length of a rectangle is 5 more than the width. The perimeter is 120. What is the length, width, and area? Please HELP
Ad libitum [116K]

Answer:

l = 32.5 units, w= 27.5 units, A = 893.75 units²

Step-by-step explanation:

width is w

length is l = 5+w

P = 2( l+w) , substitute l for 5+w

P = 2(5+w+w)

P = 2(5+2w)

P = 10 +4w

P = 120

10 +4w = 120

4w = 120-10

4w = 110

w= 110/4

w= 27.5 units

l = 5+w = 5+ 27.5 = 32.5 units

A = l*w = 27.5 * 32.5 = 893.75 units ²

The vertical asymptote is r = 0.
The intensity is undefined at the source.
The horizontal asymptote is I = 0.
As the distance from the source increases, the intensity goes to zero.
The intensity decreases as the distance increases.
