Answer: The total distance Fiona covers in two laps of the race = 880 meters
Step-by-step explanation:
Given : Fiona races BMX around a circular dirt course.
The radius of the course is 70 meters.
Then , Circumference of circular dirt course = 
=
![[\text{Use }\pi=\dfrac{22}{7}]](https://tex.z-dn.net/?f=%5B%5Ctext%7BUse%20%7D%5Cpi%3D%5Cdfrac%7B22%7D%7B7%7D%5D)
Now , the total distance Fiona covers in two laps of the race = 2 x (Circumference of circular dirt course)
= 2 x (440 meters)
= 880 meters
Hence, the total distance Fiona covers in two laps of the race = 880 meters
Answer:
(2)
Step-by-step explanation:
Our logarithmic expression is:
.
Remember the logarithmic property that ln(a/b) = lna - lnb. So, we can write this as:

Also, we can write square roots as powers of one-half, so √e =
. There's another log property that:
. We can apply that here for both the √e and the y³:

Finally, note that ln(e) is just 1, so we have:

The answer is thus (2).
