What is the zero in the quadratic function f(x)= 9x^2-54x-19?

Alex17521 [72]

Answer:

6.33... and 0.333...

Step-by-step explanation:

The quadratic formula is

$x=\frac{-b+\sqrt{b^2-4ac} }{2a}$ .

It is important because while some quadratics are factorable and can be solved not all are. The formula will solve all quadratic equations and can also give both real and imaginary solutions. Using the formula will require less work than finding the factors if factorable. We will substitute a=9, b=-54 and c=-19.

$x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}\\x=\frac{-(-54)+/-\sqrt{(-54)^2-4(9)(-19)} }{2(9)}\\x=\frac{54+/-\sqrt{2916+684} }{18}$

We will now solve for the plus and the minus.

The plus,,,

$x=\frac{54+\sqrt{3600}}{18}\\x=\frac{54+60}{18}\\x=\frac{114}{18}\\x=6.3$

and the minus...

$x=\frac{54-\sqrt{3600}}{18}\\x=\frac{54-60}{18}\\x=\frac{-6}{18}\\x=-0.333...$

Hi im having troble cobineing like terms -10a - 9n + 16 - 30 + 3n + 15a + 50 + a

goldenfox [79]

Answer:

6a-6n+36

Step-by-step explanation:

-10a-9n+16-30+3n+15a+50+a

Combine a...

-10a+15a= 5a+a=6a

Combine n...

6a-9n+16-30+3n+50

-9n+3n= -6n

6a-6n+ 16-30+50

Combine # w no variable

Answer: 6a-6n+36

Can someone do this for me please?! Just the answer pls

<h2>For the number 1..</h2>

<h2>angle at center = 2×angle at circumference</h2><h2>the angle at center (o) is equal to 141</h2>

therefore:

<h2>141 = 2x</h2><h2>divide both sides by 2</h2><h2>x = 70.5</h2>

option (A).

( the number 2 and 3 questions aren't correct )

Which of the following choices is the simple formula for the nth term of the following arithmetic sequence?

kkurt [141]

$\bf 7~~,~~\stackrel{7-4}{3}~~,~~\stackrel{3-4}{-1}~~,~~\stackrel{-1-4}{-5}~~,~~\stackrel{-5-4}{-9}~~,~~...$

so namely, the "common difference" d = -4, and the first term a₁ = 7.

$\bf n^{th}\textit{ term of an arithmetic sequence}
\\\\
a_n=a_1+(n-1)d\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
d=\textit{common difference}\\
----------\\
d=-4\\
a_1=7
\end{cases}
\\\\\\
a_n=7+(n-1)(-4)\implies a_n=7+(4-4n)
\\\\\\
a_n=11-4n\implies a_n=-4n+11$
