Answer:

it is an isosceles triangle

Step-by-step explanation:

the two sides of the triangle are equal in length, also the angles opposite to the equal sides are equal. so, it is called as isosceles traingle

Please help me out!!

Can do.

Arc length = radius * theta.
S=r*theta

Convert 73° to radians.
(73°)*(pi/180)
73°=1.274rad


S=(6.48in.)(1.274rad) = 8.255 in = final answer

Pls help and explain you need to simplify a equation
crimeas [40]
Your answer will be x • 4³ = 64x
When simplifying powers, the rule is that if you’re dividing two powers with the same base (in this case the base is 4), you need to subtract the powers. For example, 3³ ÷ 3² = 3 (which is 3^1).
Using this rule, we can see that 4^8 ÷ 4^5 = 4^(8-5) = 4³.
The x is on top of the fraction and we’re not dividing by an x, so it doesn’t change. Therefore your final answer is 64x.
I hope this helps!

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:

  1. Conmutativity
  2. Associativity of addition and scalar multiplication
  3. Additive Identity
  4. Additive inverse
  5. Multiplicative Identity
  6. 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.

Given m∥n, find the value of x.
kicyunya [14]

Answer:

42

Step-by-step explanation:

Given m and n are parallel:

x + 138 = 180 because these angles are supplementary

subtract 138 from both sides

x = 42
