her speed was 144 miles per hour
Answer:
4/5
Step-by-step explanation:
Just multiply 1/5 times 4, because that's the reciprocal of 1/4
To answer this question we will use the following formula for compounded monthly interest:
where A₀ is the initial amount, r is the annual interest as a decimal number and 12 is the number of years.
Notice that:
Therefore, substituting t=42, r=0.02, and A₀=120000 we get:
Simplifying the above result we get:
Answer: $277,769.75.

Answer:
(x, y) ⇒ (y, -x)
Step-by-step explanation:
Rotation 90° CW is described by the transformation ...
(x, y) ⇒ (y, -x)
_____
<em>Additional comment</em>
If you consider a point on the x-axis after a 90° CW rotation, you realize it must have been on the y-axis before the rotation. That is, the new x-value is the old y-value.
Similarly, a point on the y-axis after rotation 90° CW must have been on the -x axis before the rotation. The new y-value is the old -x value:
(x, y) ⇒ (y, -x) . . . . . (old coordinates) ⇒ (new coordinates), 90° CW
