Kind people!help me please...And a detailed solution/THANKS<br> sin^2x-0,5sin2x=0

Volgvan

This will be easier to write, and a lot easier to read, if we temporarily
use another symbol ... say, 'Q' ... to represent ' sin(2x) ' .
Here we go:

Original equation:    Q² - 0.5 Q = 0

Factor the left side:    Q (Q - 0.5) = 0

This equation is true if either factor is zero:

-- If Q=0, then sin(2x) = 0

   2x = 0°, 180°, 360°

   x = 0°, 90°, 180°

-- If (Q-0.5) = 0, then    Q = 0.5

      sin(2x) = 0.5

   2x = 30°, 150°

   x = 15°, 75°

The whole collection of solutions
between 0° and 360° :

      x = 0°, 15°, 75°, 90°, 180° .

Solve x2+6x=7 by completing the square.Which is the solution set of the equation?

NARA [144]

Answer:

x = - 7, x = 1

Step-by-step explanation:

Given

x² + 6x = 7

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(3)x + 9 = 7 + 9

(x + 3)² = 16 ( take the square root of both sides )

x + 3 = ± $\sqrt{16}$ = ± 4 ( subtract 3 from both sides )

x = - 3 ± 4

x = - 3 - 4 = - 7

x = - 3 + 4 = 1

Solution set = { - 7, 1 }

There are 11 balls numbered 1 through 11 placed in a bucket. What is the probability of reaching into the bucket and randomly dr

xz_007 [3.2K]

Answer:

Probability of drawing four balls numbered 1, 4, 8, and 6 from a 8 ball bucket = 0.041667

Step-by-step explanation:

Probability is of the ratio of number of favorable outcomes to the total number of outcomes.

Here outcome is drawing 4 balls from a 8 ball bucket.

Favorable outcome is randomly drawing four balls numbered 1, 4, 8, and 6.

Total number of ways in which 4 balls from a 8 ball bucket can be drawn is given by 8 x 7 x 6 x 5 = 1680.

Total number of ways in which drawing four balls numbered 1, 4, 8, and 6 from a 8 ball bucket is given by 8C₄

Probability of drawing four balls numbered 1, 4, 8, and 6 from a 8 ball bucket is given by

Probability of drawing four balls numbered 1, 4, 8, and 6 from a 8 ball bucket = 0.041667
