The <span>principle that helps us to determine the total number of outcomes in a sample space is the counting principle.

</span>The Fundamental Counting Principle: If there are “a” ways for one event to happen, and “b” ways for a second event to happen, then there are “a * b” ways for both events to happen.

All zeros of polynomial function 3x^4 +14x^2 -5
Marizza181 [45]

Answer:

Correct answer:  x₁ = 1 / √3 = √3 / 3  or  x₂ = - 1 / √3 = - √3 / 3

Step-by-step explanation:

Given:

3 x⁴ + 14 x² - 5 = 0   biquadratic equation

this equation is solved by a shift  x² = t and get:

3 t² + 14 t - 5 = 0

t₁₂ = (-14 ± √14² - 4 · 3 · 5) / 2 · 3 = (-14 ± √196 + 60) / 6

t₁₂ = (-14 ± √256) / 6 = (-14 ± 16) / 6

t₁ = -5   or  t₂ = 1 / 3

the solution t₁ = -5 is not accepted because it cannot be x² = -5

we accepted  t₂ = 1 / 3

x² =  1 / 3  ⇒  

x₁ = 1 / √3 = √3 / 3  or  x₂ = - 1 / √3 = - √3 / 3

The anwser is


4/5x = 16
5/4 x(multiply) 4/5x = 5/4x 16
X= 5x(multiply)4
X=20
(Not 100% sure about the work but the anwser is right)

Answer:

11

Step-by-step explanation:

W^7/W^-2=W^7+2=W^9 ( when divide subtract the exponent (7-(-2))

W^?/W² = W^?-2

W^9=W^(?-2)

9=?-2

?=11

W^7/W^-2 = W^11/W²
