Answer:
1. Because it is an integer.
2. Because it is a terminating decimals.
3. Because it is a terminating decimal as well as an integer.
4.Because it is a natural number.
5.Because it is a terminating decimal when divided.
6. Because it is a whole number.
7. Because it is a natural number.
8. Because it is a terminating negative decimal when divided(simplified basically).
Step-by-step explanation:
Irrational numbers include:
Non terminating,and non recurring decimals.

The frequency of the emitted radio waves is:
The energy of a photon is given by:
where h is the Planck constant and f is the photon frequency. Using the frequency given by the problem, we can find the energy of each photon of this radiation:

Solution:
There is no saddle point (DNE). However, there is local maximum at (1, 1/2) for the given function.
Explanation:
we have function of two variables f(x,y)= 9-2x+4y-x^2-4y^2
we will find the values by partial derivative with respect to x,y,xy
= -2 -2x
= 4 -8y
to find the saddle point we should first find the critical points so equate
-2 -2x=0 and 4 -8y=0
we get x= 1 and y =1/2 so, critical points are (1,1/2)
to find local maximum or minimum we have to find ,
and
formula is *
-
=0
= -2
= -8
=0
putting values in formula
(-2)*(-8) -0 =16 > 0, and < 0 and
<0
so, here we have local maximum
we have no saddle point for this function by using the same formula we used to find extrema.
