Find all values of x in the interval [0, 2π] that satisfy the equation. 6sin²(x) = 3

34kurt

Answer:

The solutions are π/4, 3π/4,5π/4,7π/4

Step-by-step explanation:

The given equation is

6sin²(x) = 3

Divide by 6 to get:

${ \sin}^{2} (x) = \frac{1}{2}$

This implies that;

$\sin(x) = \pm \frac{ \sqrt{2} }{2}$

$\sin(x) = \frac{ \sqrt{2} }{2}$

$x = \frac{\pi}{4}$

in the first quadrant

$x = \frac{3\pi}{4}$

in the second quadrant.

$\sin(x) = - \frac{ \sqrt{2} }{2}$

$x = \frac{5\pi}{4}$

in the third quadrant

$x = \frac{7\pi}{4}$

Line EF is the median of the trapezoid ABCD. The median connects the midpoint of the legs of a trapezoid. Use the diagram to fin

FromTheMoon [43]

Answer:

median: 15
base: 18

Step-by-step explanation:

The median is the average of the lengths of the two bases:

5x -20 = (12 + (4x -10))/2

5x -20 = 2x +1

3x = 21 . . . . . add 20-2x

x = 7

Then the lengths are ...

median = 5x -20 = 5·7 -20 = 15

base = 4x -10 = 4·7 -10 = 18
