The value of h is 11.3.
Solution:
Given data:
The triangle is a right triangle.
θ = 45° and opposite side of θ = 8
The value of sin 45° =
Using trigonometric formula,
Do cross multiplication.
h = 11.3
The value of h is 11.3.
The average number of daylight hours, y, in a month for a particular city over the course of a 12-month year can be determined u
sing the equation y = 2.375sin((StartFraction pi Over 6 EndFraction x minus StartFraction pi Over 2 EndFraction))+12.125, where x = 0 represents December, x = 1 represents January, etc.

Answer:
Yes. It is a vector space over the field of rational numbers
Step-by-step explanation:
An element of the set
has the form
where are rational coefficients.
The operations of addition and scalar multiplication are defined as follows:
The properties that , together the operations of vector addition and scalar multiplication, must satisfy are:
- Conmutativity
- Associativity of addition and scalar multiplication
- Additive Identity
- Additive inverse
- Multiplicative Identity
- Distributive properties.
This is not difficult with the definitions given. The most important part is to show that has a additive identity, which is the zero polynomial, that is closed under vector addition and scalar multiplication. This last properties comes from the fact that
is a field, then it is closed under sum and multiplication.
