Answer:

  • Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 90° clockwise from point A.

Step-by-step explanation:

90° clockwise rotation of point A (1, 4) around the origin

<u>Answer options</u>

  • Create a line perpendicular to the y-axis from point A, and locate a point on the perpendicular line that is equidistant to the distance between the y-axis and A.
  • <u>Incorrect. It describes the reflection over y axis</u>

  • Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 90° clockwise from point A.
  • <u>Correct</u>

<u></u>

  • Create a line perpendicular to the x‒axis from point A, and locate a point on the perpendicular line that is equidistant to the distance between the y-axis and A.
  • <u>Incorrect. It is the transformation by 1 unit down.</u>

  • Create a circle with point A as its center and a radius of the origin and point A, then locate a point on the circle that is 90° counterclockwise from point A.
  • <u>Incorrect. It is the transformation of origin but not point A</u>

It takes ten identical pieces to form a circular track for a pair of toy racing cars. If the inside arc of each piece is 3.4 inc
dsp73
 <span>Length of outer track = sum of length of 10 pieces = circumference of the outer circle 


if R is the Radius of outer circle then... 

Circumference of the outer track = 2pi*R 


Similarly the circumference of the inner track (with radius r) = 2pi*r 


length of each outer piece is 3.4 inch more than length of inner piece 

So total outer length is 10*3.4 =34 inches more than the inner length. 


=> Outer Circumference - Inner Circumference = 34 inches 

=> 2pi*R - 2pi*r = 34 

=> 2pi(R -r) = 34 

=> R-r = 34/2pi = 5.41 inches 

=> R-r = Width of the track = 5.41 inches</span>

a triangle has a perimeter of 10x+2 . two sides have lengths of 5x and 2x+9 what is the length of the 3rd side
stiks02 [169]
Since all the sides add up to 10x+2, that means that 10x-2-<side1>-<side2>=<side3>. Plugging it in, we have 10x-2-5x-(2x+9)=side3, and 5x-2-(2x+9)=side3, then expanding it to 5x-2-2x-9=3x-11=side3

3y = -x + 3

y= (-1/3)x + 1

perpendicular: 3

y + 1 = 3(x - 6)
y + 1 = 3x - 18

y = 3x - 19
