We know that
applying the law of cosines
c²=a²+b²-2*a*b*cos C

in this problem
a=10 m
b=11 m
c=13 m
C=?

c²=a²+b²-2*a*b*cos C----> cos C=[a²+b²-c²]/[2*a*b]
cos C=[10²+11²-13²]/[2*10*11]----> cos C=0.2364
C=arc cos (0.2364)----> C=76.33°

the answer is
76.3°

Which expression is a polynomial?<br><br> –13
olasank [31]

Polynomials are <em>algebraic</em> expressions whose <em>standard</em> form is defined below:

p(x) = \sum \limit_{i=0}^{n} c_{i}\cdot x^{i}

The expression p(x) = - 13 represents a <em>zeroeth</em> polynomial.

<h3>What is a polynomial?</h3>

Herein we must present what the form of polynomials are. Polynomials are <em>algebraic</em> expressions whose <em>standard</em> form is defined below:

p(x) = \sum \limit_{i=0}^{n} c_{i}\cdot x^{i}     (1)

Where:

  • c_{i} - i-th coefficient
  • n - Grade
  • x - Independent variable

An example is the expression p(x) = - 13, <em>real </em>numbers can be define as <em>zeroeth</em> polynomials. In this regard, the example can be seen as:

p(x) = 0 · xⁿ + 0 · xⁿ⁻¹ + ... + 0 · x² + 0 · x - 13

<h3>Remark</h3>

The statement is incomplete. We decided to re-define the statement to what polynomials are.

Carleen has 104 pieces of candy leftover from Halloween. She would like to distribute them evenly to the 8 kids on her block. Wr
algol13

Answer:

8x = 104

x = 13

Step-by-step explanation:

Since we are trying to distribute it evenly, we divide 104 by 8 to get 13 pieces of candy per child.

The equation is saying 8 kids times <em>x</em> amount of candy per kid is equal to a total amount of 104 pieces of candy.
