Answer:
The correct option is;
90 degrees counterclockwise rotation
Step-by-step explanation:
The coordinates of the preimage before rotation = K(17, -12)
The coordinate of the image of the preimage after rotation = K'(12, 17)
Therefore, the rotation transformation, transforms, the preimage (x, y) to the image (-y, x), which is equivalent to a rotation of 90 degrees counterclockwise
Answer:
it looks like all of them should be 90 if I am not incorrect
Step-by-step explanation:
I believe the slope is 2 if I’m not wrong
Y intercept is (0,-0.7) and X intercept is (-1.2 ,0)
“The breaking distance is directly proportional to the square of its speed”
Using your variables, this means: d = k•b^2
k here is some unknown (and for this question irrelevant) number.
Now if b (the speed) is increased by 200%, then your new speed is b+2b = 3b. The 2b is the 200% increase.
Throw 3b into the first equation we have the new d as:
d = k • (3b)^2
Simplifying this, you have d = k•9b or d=9kb
This means the new braking distance is 9 times the original braking distance.
