T-4t2+ 2t3 what is the degree of the polynomial

Mathematics
1 answer:
Tema [17]3 years ago
6 0

Answer:

The given polynomial is a<u> third degree</u> polynomial.

Step-by-step explanation:

Given polynomial:

t-4t^2+2t^3

To find the degree of the polynomial.

Solution:

The degree of the polynomial is defined by the highest exponent of the variable in the given polynomial. In other words, it is the exponent of the highest degree term.

For a polynomial:

x^a+x^b+x^c

<em>where a>b>c, the degree of the polynomial can be given as the ath degree as a is the highest exponent of the variable x.</em>

Thus, for the polynomial:

t-4t^2+2t^3

The leading term is 2t^3 since the term has the highest degree of the variable t and the degree of the polynomial = 3

Part 1

<h3>Answer:   13</h3>

---------------------

Explanation:

We'll replace every copy of x with -3. Then use PEMDAS to simplify.

f(x) = -2x+7

f(-3) = -2(-3)+7

f(-3) = 6+7

f(-3) = 13

===========================================================

Part 2

<h3>Answer:  -11</h3>

---------------------

Explanation:

We work backwards in a sense compared to what part 1 did. Instead of finding f(x) based on x, we determine what x must be for a given f(x).

We'll replace f(x) with 29 and solve for x like so

f(x) = -2x+7

29 = -2x+7

-2x+7 = 29

-2x = 29-7

-2x = 22

x = 22/(-2)

x = -11

Note how if you replaced x with -11, we'd get,

f(x) = -2x+7

f(-11) = -2(-11)+7

f(-11) = 22+7

f(-11) = 29

which helps confirm we have the correct answer.

Initially the top shelf has no books placed on

Then books added to this:

  • 1+2+3= 6

And now all 4 shelves have same amount of books. So total number is:

  • 4*6= 24 books

There are 24 books in the bookcase

at the school fair, of the people are under 16 years old. one-third of the people are teachers. if there are at least 21 one tea
Diano4ka-milaya [45]
Hello there!

Your correct answer will be 35 people under 16.

You know that 1/3 of the people are teachers, which means that 2/3 of people are left. Now, you need to get to the decimal value (.667). Make that number 1.667, because there will not be less teachers than students. Now, multiply:

1.667 x 21 = 35

There you go!
