Answer:

Part I:  The degree of a polynomial is the greatest of the degrees of its terms.

Part II:  In order to write a polynomial in descending order, you must write the terms with the exponents decreasing from left to right.

Part III: A. -4x² + 11x - 12, degree = 2,

B. 5x³ + 4x + 14, degree = 3.

Step-by-step explanation:

Part I : Since the degree of a polynomial is the highest power of its monomials ( single term ),

e: degree of is 5.

Thus, in part I, the correct option is 'greatest'

Part II: When we write a polynomial then we write the terms of the polynomial in descending order of their degrees.

Thus, in part II the correct option is 'least'

Part III: A.  

∵ -4x² has the highest power in the polynomial.

⇒ Degree = 2,

Also, in the polynomial descending order of degrees,

2 > 1 > 0

⇒ polynomial in descending order,

B.  

Combining like terms,

∵ 5x³ has the highest degree,

⇒ Degree = 3,

Also, the order of the degrees in the polynomial is,

3 < 2 < 1 < 0

Thus, the polynomial in descending order,

zhuklara [117]

Answer:

Your answer is 3x = 15

Step-by-step explanation:

3x = 15

Since 3 is being multiplied by x, we divide both sides by 3.  3x/3 cancels out, and you're left with x.

15/3 = 5

x = 5

This is my take using algebraic methods.

Find the vertex by using the formula -b/2a
To find a and b, we must know that a and b are located at y = ax^2 + bx + c.
We find that b is 4 and a is 1 by looking at the given quadratic function.
The answer is A. -4/2(1) because the question is looking for the correct steps to find the answer.

PLEASE help with these math questions
SIZIF [17.4K]
Questions 1, 2, 3, and 4 are exercises to give you practice with
common denominators.  For each of these questions, change all
the fractions to common denominators, and the answers jump out at you.

#1).  5/12 = 25/60
         2/5  =  24/60
Make um negative, and then you'll have the answer right away.


#2).  The one that's negative is obviously the least.
Both positive ones must be bigger than the negative one.
For the positive ones:

           2/5  =  6/15
           2/3  =  10/15 .
Now it's easy.


#3).  This is tough.  The least common denominator is  2,520 !
It's probably easier to just do the divisions and get the decimals
for each fraction.

               -5/8  =  -0.625
               -7/9  =  -0.777...
               -4/5  =  -0.8
               -3/7  =  -0.428...
Now it's easy to line um up.


#4).  Sneaky one.
      Look closely at each fraction.
      B, C, and D are all less than 1, so they're not between 1 and anything more than 1.
      8/5 is the only one that's more than 1.     


#5).  A fraction is just a short way to write a division problem.
When you see a fraction, it means

               "the top number divided by the bottom number" .

When you actually do the division, the quotient you get
is the decimal form of the fraction.

To change a decimal into a percent,
move the decimal point two places that way  ==> .

The numbers in the boxes at the bottom of #5 are the correct numbers,
but they both should be negative.  (because the -3/8 is negative)

the hypotenuse of a 30-60-90 degree right triangle has a measure of 10. what is the measure of the shortest side
VARVARA [1.3K]

Answer:

5

Step-by-step explanation:

A 30-60-90 triangle's sides equal as follows:

Hypotanuse= x (a number)

Long side= x/2( also can be calculated as x* 1/2) * \sqrt{3}

Short side = x/2 or x * 1/2
