Answer:

The solution is x = + 0.77 , -0.77

Step-by-step explanation:

The equation is

x^3 - 3x^2 - 4 = \frac{1}{x} -1 +5\\x^4 -3x^3 -4x = 1-4x\\x^4 - 3x^3 = 1\\x^3 (x-3) = 1\\\\x^4 -3x^3 -1 = 0\\x^4 -3x^3 -1

The solutions to the equation is

x = + 0.77 , -0.77

1. The total number of seats in an auditorium is modeled by f(x) = 2x2 – 6x, where x represents the number of rows. How many row
irakobra [83]

Answer:

Jose's solution is not correct, the auditorium has 16 rows

Step-by-step explanation:

we have

f(x)=2x^{2} -6x

where

f(x)------> is the total number of seats in an auditorium

x----> represents the number of rows

How many rows are there in the auditorium if it has a total of 416 seats?

Find the value of x for f(x)=416 seats

substitute the value of f(x) in the equation

416=2x^{2} -6x

2x^{2} -6x-416=0

Using a graphing calculator

The values of x are x=-13, x=16

The solution is

x=16 rows because the number of rows can not be a negative number

Which of the following functions is graphed below?
Nadya [2.5K]

Answer:

B.

Step-by-step explanation:

The function above the x-axis looks like a parabola, so it must have an x^2 term. It also has an open circle, so it must have a > symbol.

The function below the x-axis has a closed circle, so it must have a <= symbol. It is also a 3rd degree polynomial.

Answer: B.
