Answer:

900m

Rewrite 2sin2x + 3 cos x − 3 in terms of cos x

Answer:

-2cos²(x) +3cos(x) -1

Step-by-step explanation:

Use the "Pythagorean identity" to replace sin²(x).

sin²(x) +cos²(x) = 1

Then ...

2sin²(x) +3cos(x) -3 = 2(1 -cos²(x)) +3cos(x) -3

= -2cos²(x) +3cos(x) -1

Which of the following is a solution of x2 + 2x + 8?

zubka84 [21]

Using the quadratic equation we get:
$\frac{ - 2 + - \sqrt{4 - 32} }{2} = \frac{ - 2 + - \sqrt{ - 28} }{2}$

Factoring out 2 we get
$\frac{ - 2 + - 2\sqrt{ - 7} }{2} = - 1( + - ) \sqrt{ - 7}$
Factoring out the imaginary number:
$- 1 + \sqrt{7} i \: (and) \: - 1 - \sqrt{7} i$
So b.
