I believe the answer is B.
Explanation: In the problem, it states that “Karen says MOST middle school students’ favorite band is Rhonda and the Gees.” Pay attention to the keyword, most. Only 65 students like Rhonda and the Gees, so it is too small to represent a middle school of 1,156. So, therefore, the answer should be B.
The surface is parameterized by
and the normal to the surface is given by the cross product of the partial derivatives of 
:
It looks like you're given
Then the normal vector is
Now, the point (2, 2, 0) corresponds to u and v such that
and solving gives 
, so the normal vector at the point we care about is
Then the equation of the tangent plane is
9514 1404 393
Answer:
f(x)=0
Step-by-step explanation:
For the function to be both even and odd, you must have ...
f(-x) = f(x) = -f(-x)
Adding f(-x) we have ...
2f(-x) = 0
Then dividing by 2 and recognizing f(-x) = f(x), we have ...
f(-x) = f(x) = 0
Answer:
900 = 2 * 2 * 3 * 3 * 5 * 5 = 2^2 * 3^2 * 5^2
Step-by-step explanation:
900/2 = 450
450/2 = 225
225/3 = 75
75/3 = 25
25/5 = 5
5/5 = 1
900 = 2 * 2 * 3 * 3 * 5 * 5 = 2^2 * 3^2 * 5^2
