Answer:
Step-by-step explanation:
Alana and 2 friends evenly split the meal. This means there are 3 people in total.
Since they said each person owes $14.68. To find the total you just multiply $14.68 by 3.
Total = $14.68 x 3 = $?
Answer:
The plane's distance from the radar station will increase about 8 miles per minute when it is 5 miles away from it.
Step-by-step explanation:
When the plane passes over the radar station, the current distance is the altitude h = 2. Then it moves b horizontally so that the distance to the station is 5. We can form a rectangle triangle using b, h and the hypotenuse 5. Therefore, b should satisfy
h²+b² = 5², since h = 2, h² = 4, as a result
b² = 25-4 = 21, thus
b = √21.
Since it moved √21 mi, then the time passed is √21/540 = 0.008466 hours, which is 0.51 minutes. Note that in 1 minute, the plane makes 540/60 = 9 miles.
The distance between the plane and the radar station after x minutes from the moment that the plane passes over it is given by the function

We have to compute the derivate of f in x = 0.51. The derivate of f is given by

also,

The plane's distance from the station will increase about 8 miles per minute.
Answer:
The fencing Chaz used for the pen is 56.67 feet
Step-by-step explanation:
Fencing interprets to circumference
If the radius of the pen is 9 ft
circumference = 
= 2*(22/7)*9
= 396/7
= 56.67 ft
