Answer: (3x+2)(x+3)
Step-by-step explanation: Factor by grouping.
I hope this helps you out.
Alright so lets start with an arbitrary amount of students. Just to help us visualize the problem.
Say, 100 students for the first year when it was founded?
So far,
1996 - 100 students
From 96' to 97', it doubles. So:
1996 - 100 students
1997 - 200 students
From 97' to 98', it doubles AGAIN.
1996 - 100 students
1997 - 200 students
1998 - 400 students
So, what the percentage increase from 100, to 400?
Well, 100 x 4 gives us 400, so it's a 400 percent increase.
R - 18 = 50
r = 50 + 18 = 68
Hence Rick is 68 yrs old
Answer:
Step-by-step explanation:
We can write the given expression as :
As given, f = ∇f.
∇f = 
+ 
+
We can write the partial derivative with respect to x, y and z.
___(Equation 1)
______(Equation 2)
______(Equation 3)
Take equation 2 and integrate with respect to y,
----------Equation 4
Derivate both sides w.r.t x , we get :
or
integrate
a(x,z)=b(z)
put in equation 4 ,
we get :
take derivative wrt z
we can take here:
integrate:
b(z) = C
The function can be written as :
from equation 4 :
Where C is a constant.
