Answer:
716.31454 and 228.01π
Step-by-step explanation:
Area = πr^2
π · 15.1^2 ≈ 716.31454
Area in terms of pi = 228.01π

The angles should add to 540, so
b+ (3/2)b+(b+45)+(2b-90)+90=540
First combine like terms
5.5b+45=540
Then subtract 45 from both sides
5.5b=495
Divide both sides by 5.5
b=90
Final answer: b=90
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.
Answer:
<h2>m∠1 = 93°</h2>
Step-by-step explanation:
The vertical angles have the same measure.
Therefore, if ∠1 and ∠2 are vertical angles and m∠2 = 93°, then m∠1 = 93°.
