Answer:
120
Step-by-step explanation:
We are given that the function for the number of students enrolled in a new course is  .
.
It is asked to find the average increase in the number of students enrolled per hour between 2 to 4 hours.
We know that the average rate of change is given by,
 ,
,
where f(x)-f(a) is the change in the function as the input value (x-a) changes.
Now, the number of students enrolled at 4 = f(4) =  = 255 and the number of students enrolled at 2 = f(2) =
 = 255 and the number of students enrolled at 2 = f(2) =  = 15
 = 15
So, the average increase  =
 =  =
 =  = 120.
 = 120.
Hence, the average increase in the number of students enrolled is 120.
 
        
             
        
        
        
In three dimensions, the cross product of two vectors is defined as shown below

Then, solving the determinant

In our case,

Where we used the formula for AxB to calculate ixj.
Finally,

Thus, (i+j)x(ixj)=i-j
 
        
             
        
        
        
Answer:
Step-by-step explanation:
When the exponent is attached to the trig function like that, its essentially the same thing as taking the entire function to that power.
tan^2(x) = (tanx)^2
 
        
             
        
        
        
Answer: B. (2,2)
Step-by-step explanation:
The vertex of the parabola in the form  is (h, k).
 is (h, k).
 
        
             
        
        
        
16 = 48/3
48 divided by 2 = 24
There is 24 students in the club.
