T^3(8 + 9t) - (t2 + 4) (2 – 3t)

Mathematics
1 answer:
mezya [45]4 years ago
4 0

Answer: a & b

<u>Step-by-step explanation:</u>

    t³(8 + 9t) - (t² + 4)(2 - 3t)

=   8t³ + 9t⁴ - (2t² - 3t³ + 8 - 12t)

=   8t³ + 9t⁴ - 2t² + 3t³ - 8 + 12t

=   9t⁴ + 11t³ - 2t² + 12t - 8

a) The simplified expression is a polynomial.  TRUE

b) The simplified expression has a constant term.  TRUE

c) The simplified expression is cubic.  False - it is degree 4

d) The simplified expression has four terms.  False - it has 5 terms

e) The simplified expression is a trinomial   False - it has 5 terms

Factor completely 4h2 g. H(4h g) g(4h2) Prime gh(4h 1).
elena55 [62]

The expression can be divided by one and itself only. Then the expression is a prime expression. The correct option is C.

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

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The expression is \rm 4h^2 + g

The expression can be written as

\rm (2h)^2 + g

The expression can not be the real factor.

Since the expression can be divided by one and itself only.

Then the expression is a prime expression.

Thus, the correct option is C.

More about the factorization link is given below.

Describe and correct the error in determining which type of function the table represents.
topjm [15]

Answer:

<em>"Consecutive y-values change by multiplying previous value by a constant amount. So, the table represents an exponential function."</em>

Step-by-step explanation:

In reality, the table represents an exponential function instead of a linear function, since values on domain change arithmetically at constant rate, whereas values on range change geometrically at constant rate.

Correct phrase may be:<em> "Consecutive y-values change by multiplying previous value by a constant amount. So, the table represents an exponential function."</em>

Name the polynomial based on its degree and number of terms. 2 - 11x^2 - 8x + 6x^2
kumpel [21]

Step-by-step explanation:

This polynomial has like terms that can further be simplified

2 - 11x^2 + 6x^2- 8x

2 - 5x^2 - 8x

multiply by negative to take 2 to the right.

-(2 - 5x^2 - 8x)

= 5x^2 + 8x - 2

It's named a Second Degree Polynomial because the highest degree(exponent) of x in the final solution is 2.

it has 3 terms : 5x^2 , 8x , 2
