List the sides of each triangle from shortest to greatest

True [87]

A) First, we need to calculate x. We can do this by doing: 180-(70+50), which is nothing but 60.

Since the largest angle is 60, it means that the side opposite of it is the largest side. Which in this case, side AB.

So the largest side is AB.

Now, let's take a look at the smallest angle which is <B, because AC is the opposite of this angle, it must also be the smallest side.

We're left with angle <50, which is "medium" sized? Obviously, this can just be put in the middle (Side BC)

So, for response A, you should get AC, BC, AB.

Now for problem B, it's the same steps we did above. If you replicate what we did you should get PQ, PR,RQ.

Please let me know how I did.

Happy studying!

Given that p is an integer, q = -12 and the quotient of p/q is -3, find p

sergejj [24]

I think it’s p=36 because you have to do the opposite on both sides..

So..
q=-12
P/-12=-3
+12 *12
P=36

Let H be the set of all polynomials having degree at most 4 and rational coefficients. Determine whether H is a vector space. If

Verizon [17]

Answer:

Yes. It is a vector space over the field of rational numbers $\mathbb{Q}$

Step-by-step explanation:

An element $p$ of the set $H$ has the form

$p(x)=a_{0}+a_{1}x+a_{2}x^{2}+a_{3}x^{3}+a_{4}x^{4}$

where $a_{0},a_{1},a_{2},a_{3},a_{4}$ are rational coefficients.

The operations of addition and scalar multiplication are defined as follows:

$p(x)+q(x)=(a_{0}+a_{1}x+a_{2}x^{2}+a_{3}x^{3}+x_{4}x^4)+(b_{0}+b_{1}x+b_{2}x^{2}+b_{3}x^{3}+b_{4}x^{4})=(a_{0}+b_{0})+(a_{1}+b_{1})x+(a_{2}+b_{2})x^{2}+(a_{3}+b_{3})x^{3}+(a_{4}+b_{4})x^{4}$

$\lambda p(x)=\lambda (a_{0}+a_{1}x+a_{2}x^{2}+a_{3}x^{3}+a_{4}x^{4})=\lambda a_{0}+\lambda a_{1}x+\lambda a_{2}x^{2}+\lambda a_{3}x^{3}+\lambda a_{4}x^{4}$

The properties that $H$ , 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 $H$ 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 $\mathbb{Q}$ is a field, then it is closed under sum and multiplication.
