Answer:
for X its 90 degrees
Step-by-step explanation:
If its a right angle it is 90 degrees
Rotation 270 counterclockwise about origin is easy, swap the x and y then reverse the sign of the y
so (x, y) rotates to (y, -x)
Sadly to change the centre we need to translate the centre to the origin, rotate and the translate back.
In this case that means adding -1, 2 to x,y respectively, rotating, adding 1, -2 to x,y respectively
B(2, 3) translates to (1, 5) which rotates to (5, -1) and translates back to B’(6, -3)
C(6, -4) translates to (5, -2) which rotates to (-2, -5) and translates back to C’(-1, -7)
D(7, -6) translates to (6, -4) which rotates to (-4, -6) and translates back to (-3, -8)
E(3, -5) translates to (2, -3) which rotates to (-3, -2) and translates back to (-2, -4)
The translation is much easier simply moving each point 8 to the right
B’(2, 11), C’(6, 4), D’(7, 2) and E’(3, 3)
Using the grid will everything clear!
13(y+7)=3(y-1)
13y+91=3y-3
13y-3y=-91-3
10y=-94
-94/10
Y=-9.4
Ello! The answer is $60.59, because if you do
568x 0.16x 0.666667 = 60.58669696
Now, you obviously can’t type out all those numbers so you simplify which gets you 60.59!
I hope this helps you! :)
Answer:
The median is 10 and the mean is 10.2
Step-by-step explanation:
Median: the middle number -> 6,8,10,11,16
Mean:
6 + 8 + 10 + 11 + 16 = 51
51/5 = 10.2
