What are the solutions of the equation x4 – 5x2 – 14 = 0? Use factoring to solve.

Answers

Answer 1

Answer: We will use factoring: $x^(4) -5 x^(2) -14 = 0 \n x^(4) -7 x^(2) +2 x^(2) -14 =0 \n x^(2) ( x^(2) -7)+2( x^(2) -7)=0 \n ( x^(2) -7)( x^(2) +2)=0$
x² - 7 = 0
x² = 7
x = $√(7)$
or x= $-√(7)$
x² + 2 = 0
x² = - 2, this part of equation has no solutions.

How would you convert 5 feet 6 inches to inches

Answers

66 inches. Since 1 foot is equal to 12 inches, all you need to do is to multiply 5 with 12. The answer will be 60. Since 6 inches are already given for the answer, just add up 60 with 6 for you to get 66 inches which is equivalent to 5 feet 6 inches.

Converting 5 feet 6 inches to inches is: 66 inches.

Here, we have,

given that,

convert 5 feet 6 inches to inches

The orbital period, P, of a planet and the planet’s distance from the sun, a, in astronomical units is related by the formula P = a Superscript three-halves. If Saturn’s orbital period is 29.5 years, what is its distance from the sun?

Answers

Answer:

9.54731702 astronomical units

Step-by-step explanation:

$P=a^{(3)/(2) }$

Substitute this value in the equation above:

$29.5=a^{(3)/(2) }$

⇒ $(29.5)^{(3)/(2) } =a$

⇒ $a=9.54731702$ $astronomical$ $units$

Hence, its distance from the sun is 9.54731702 astronomical units.

The sum of the roots of the equation (1/2)x^2-(5/4)x-3=0

a.5/2
b.2
c.1/2

Answers

(1/2)x² - (5/4)x - 3 = 0

0.5x² - 1.25x - 3 = 0

Comparing to the quadratic function, ax² + bx + c = 0,
a = 0.5, b = -1.2, c = -3.

Sum of roots = -b/a = -(-1.25)/0.5 = 1.25/0.5 = 2.5

2.5 = 5/2 Option (a)

A)5/2 is the answer.
