Answer:

not proportional

Step-by-step explanation:

First , let's find the speed of each person by dividing the distance traveled and the time.

Using B to represent Bob's speed and K to represent Kelly's speed , we have:

$B=\frac{20}{4} = 5 mph\\K=\frac{14}{3}= 4.666 mph\\\\$

The speeds 5 and 4.666 are not multiples , so they are NOT proportional.

$A' =(-y,x)$

Step-by-step explanation:

Given

Represent point A as thus;

$A = (x,y)$

Required

Determine the new position of A, when rotated counterclockwise

The new position will be denoted as A'

When a point is rotated counterclockwise, we start by switching the positions of x and y as follows:

$Pos = (y,x)$

Then, y is negated to give A'

$A' =(-y,x)$

Answer:

(x + 3)² + (y -2)² = 4

Explanation:

Circle Formula: (x -h)² + (y -k)² = r²

"r" is radius, "h" is x coordinates of center, "k" is y coordinate of center.

Here given:

h = -3, k = 2, r = 2

Insert values:

(x -(-3))² + (y -2)² = 2²

(x + 3)² + (y -2)² = 4
