Whole numbers are numbers without decimal points greater than 0.
The set of whole numbers is:

In the introductory part of this solution, I stated that:
- Whole numbers do not have decimal point
- The smallest whole number is 0
This means that the following numbers are whole numbers:
1, 9, 10, 67
While the following numbers are not:
-1, 9.0, 1.0, -67
Let W be the set of whole numbers; the set is:

The dots after 4 means the set still continues

Answer:
No real roots
Step-by-step explanation:
Roots of a quadratic are the x-intercepts of the graph
x is timed by .5 in the first one (A) which would make it the linear function.

Answer:
X = 0, π/2 in the interval [0, 2pi).
Step-by-step explanation:
Use the auxiliary angle method:
R sin(x + a) = Rsin x cos a + Rcos x sin a = 1
sin x + cos x = 1
Comparing coefficients:
R cos a = 1 and R sin a = 1, so
tan a = R sin a / R cos a = 1
So a = π/4 radians.
Also R^2(sin^2 a + cos^2 a) = 1^2 + 1^2 = 2
Therefore R = √2.
So √2 sin (x +π/4 = 1
sin x + π/4 = 1/√2
x + π/4 = π/4
x = 0 radians
Also
x = 0 + π/2 = π/2.
