Given g(x) = x² - 6x - 16, which statement is true?
inn [45]

The correct choice of this question with the given polynomial is <em>"The zeros are </em>-2<em> and </em>8<em>, because the factors of g are (x + </em>2<em>) and (x - </em>8<em>)"</em>. (Correct choice: H)

<h3>How to analyze a second orden polynomial with constant coefficients</h3>

In this case we have a second order polynomial of the form <em>x² - (r₁ + r₂) · x + r₁ · r₂</em>, whose solution is <em>(x - r₁) · (x - r₂)</em> and where <em>r₁</em> and <em>r₂</em> are the roots of the polynomial, which can be real or complex numbers but never both according the fundamental theorem of algebra.

If we know that <em>g(x) =</em> <em>x² -</em> 6 <em>· x -</em> 16, then the <em>factored</em> form of the expression is <em>g(x) = (x - </em>8<em>) · (x + </em>2<em>)</em>. Hence, the correct choice of this question with the given polynomial is <em>"The zeros are </em>-2<em> and </em>8<em>, because the factors of g are (x + </em>2<em>) and (x - </em>8<em>)"</em>. \blacksquare

The explicit formula for a sequence is<br> an=−2+3/2(n−1)<br> What is the 21st term of the sequence?
Anni [7]

Step-by-step explanation:

From the given question it appears that (n-1) is in the numerator's place, if it is so, then let us solve it.

a_n =  - 2 +  \frac{3}{2}(n - 1)   \\ \\  \therefore \: a_{21} =  - 2 +  \frac{3}{2}  (21 - 1) \\  \\   \therefore \: a_{21} =  - 2 +  \frac{3}{2 }   \times \: 20\\  \\ \therefore \: a_{21} =  - 2 + 3 \times \: 10  \\  \\ \therefore \: a_{21} =  { -2  + 30}   \\  \\ \therefore \: a_{21} =  28   \\  \\  \huge \red{ \boxed{\therefore \: a_{21} =   28}  } \\  \\
