Answer:
A. 90 degrees clockwise rotation
Step-by-step explanation:
Of we have a coordinate axis (x,y), if this axis is rotated 90° clock wide, the resulting coordinate of the pre-image will be the coordinate (y -x). Note that the coordinates was swapped and then the new y coordinate negated.
Given the coordinate K(24, -15). If we rotate this clockwisely, first we swap the coordinate axis to have (-15, 24)
Them we will negate the new y coordinate axis to have;
K'(-15, -24)
Therefore the correct answer is 90° clockwise rotation.
Answer:
Option D (7, -3)
Step-by-step explanation:
We know that the general equation of an ellipse has the form:
Where the point (h, k) are the coordinates of the center of the ellipse
In this case the equation of the ellipse is:
Then
So The coordinates of the center of the ellipse are (7, -3)
Answer:
-23
Step-by-step explanation:
As I increases by 18, y decreases by 12. From the last value in the table, I needs to increase by 2·18 for it to become zero. Hence the y-intercept will be 2·12 less than the last value in the table:
1 - 2·12 = -23 . . . the y-intercept
Distance = speed x time
2.257 x 9.111 = 20.563527 or 20
Answer: Celine, 4092 ml
Step-by-step explanation:
Given
1 bottle contains 341 ml Juice
Celine buys 2 cases of 24 bottles i.e. a total of 48 bottles
Nicole buys 3 cases of 12 bottles i.e. a total of 36 bottles
Amount of Juice Celine has
Amount of Juice Nicole has
Thus, Celine has more juice than Nicole
Celine has 4092 ml more than Nicole
