7.8456 x 10^(-4)
this means you move the decimal place to the left 4 places to get the actual value
Answer:
66045 ways
Step-by-step explanation: There are actually total of 37 student, and total of 4 jobs. But if the jobs are to be done by only one person each, then we are selecting 4 students.
So the number of ways of selecting 4 out of 37 using combination is
=37C4
=37!/(37-4)!(4!)
=37!/33!4!
=66045
Answer:
5w^22
Step-by-step explanation:
The formula is 2 (pi)r
The diameter is a 27.4 which means the radius is half of that or 13.7.
So 2 (pi)r equals 27.4 (pi)
That should be your answer
Answer:
2.5
Step-by-step explanation:
The average rate of the function f(x) from x=a to x=b is given by:
From the question, the exponential function goes through (0,30) and (20,80).
This implies that f(0)=30 and f(20)=80
Therefore the average rate of change from x = 0 to x = 20 is
The second choice is correct
