A racecar driver is trying to decrease her lap times by at least 8%. Select whether the description stated shows that the driver reached her goal. A. The original time was 2.5 minutes, and the new time is 2 minutes.
B. The original time was 4 minutes, and the new time is 3 minutes.
C. The original time was 5.25 minutes, and the new time is 5 minutes
D. The original time was 3 minutes, and the new time is 3.15 minutes.

A. The original time was 2.5 minutes, and the new time is 2 minutes.

B. The original time was 4 minutes, and the new time is 3 minutes.

Step-by-step explanation:

A. 8% of 2.5 is 0.2, but 2 minutes is faster than 2.2 minutes

B. 8% of 4 is 0.32, but 3 minutes is faster than 3.68 minutes

C. 8% of 5.25 is 0.42, 5 minutes is slower than 4.83 minutes

D. she is slower so her lap time is increasing

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
