Mathematics
1 answer:
atroni [7]3 years ago
3 0

Answer:

<u>The correct answer is A. 1 +/- i √31/2</u>

Step-by-step explanation:

Let's use the quadratic formula to solve the equation:

x² - x  + 8 = 0

Let's recall that the quadratic equation is:

x = (-b +/- √(b² - 4ac))/2a

In the equation, a = 1, b = -1, c = 8.

Replacing with the real values, we have:

x = (-b +/- √(b² - 4ac))/2a

x = (- (-1) +/- √(-1² - 4 (-1) (8)))/2(1)

x = (1 +/- √( 1 - 32)/2

x = (1 +/- √( - 31)/2

x = (1 +/- √( -1 * 31)/2

Let's recall that √ -1 = i

x = 1 +/- i √ 31/2

<u>The correct answer is A. 1 +/- i √31/2</u>

For what values of x is the rational expression below undefined?
EastWind [94]
(x-4)/(3)(x+5)(x-5)

In order for the rational expression to be undefined, the denominator must be equal to 0.

Thus, set 3(x+5)9(x-5)=0

Which graph is the solution to this system y-4x=-1y+x=4
natali 33 [55]

First, let's find the x and y intercepts

In the first equation

y - 4x = -1

Put x =0

y= - 1

(0, -1)

Put y=0 and the n solve for x

0 - 4x = -1

-4x = -1

x=0.25

(0.25 , 0)

The points for the first equation is (0, -1 ) and (0.25, 0)

Next is to find the intercts for the second equation

y + x = 4

put x=0

y = 4

(0, 4)

Put y =0

0 + x = 4

x = 4

( 4, 0)

The points for the second equation are;

(0, 4) and (4, 0)

Below is the graph

Sloan [31]
Total number of bulbs = 64
Number of defective bulbs = 10
Number of good bulbs = 64 - 10 = 54

P(5 good bulbs) = (54/64)⁵ = (27/32)⁵ = 0.428
