Answer: − 80 , − 160 , and − 320

Step-by-step explanation:

From − 5 to − 10 , you multiplied by 2 . From − 10 to − 20 , you multiplied by 2 , and so on.

− 40 ⋅ 2 = − 80

− 80 ⋅ 2 = − 160

− 160 ⋅ 2 = − 320

Find all solutions in the interval from [0,2pi) 2cos(3x)= -sqrt{2}

algol [13]

Solutions of $2cos(3x)= -\sqrt{2}$ in the interval from [0,2pi) is $x =\frac{\pi}{12}$ and $x = \frac{23\pi}{12}$ .

Step-by-step explanation:

Find all solutions in the interval from [0,2pi)

$2cos(3x)= -\sqrt{2}$

⇒ $2cos(3x)= -\sqrt{2}$

⇒ $\frac{2cos(3x)}{2}= \frac{-\sqrt{2}}{2}$

⇒ $cos3x= \frac{-\sqrt{2}(\sqrt{2})}{2{\sqrt{2}}}$

⇒ $cos3x= \frac{-2}{2{\sqrt{2}}}$

⇒ $cos3x= \frac{-1}{{\sqrt{2}}}$

⇒ $cos^{-1}(cos3x)= cos^{-1}(\frac{-1}{{\sqrt{2}}})$

⇒ $3x=\pm \frac{\pi}{4}$

⇒ $x=\pm \frac{\pi}{12}$

Cosine General solution is :

$x = \pm cos^{-1}(y)+ 2k\pi$

⇒ $x = \pm \frac{\pi}{12}+ 2k\pi$ , k is any integer .

At k=0,

⇒ $x =\frac{\pi}{12}$ ,

At k=1,

⇒ $x = - \frac{\pi}{12}+ 2\pi$

⇒ $x = \frac{23\pi}{12}$

Therefore , Solutions of $2cos(3x)= -\sqrt{2}$ in the interval from [0,2pi) is $x =\frac{\pi}{12}$ and $x = \frac{23\pi}{12}$ .

May I please receive help?

Nata [24]

The Isosceles triangle has two equal side
So 35 + 35 + the another angle = 180
The another angle = 110
The straight angle = 180 - 110 = 70
The Isosceles triangle = 70 + 70 + x = 180
So x = 40

Alex73 [517]

Answer: 180.

Step-by-step explanation:

Appetizers = 5 types

drinks = 3 types

Sandwiches = 4 types.

Solution:

This is a combination problem.

For appetizers

= 5C2

= 10.

For drinks

= 3C2

= 3.

For sandwiches

= 4C2

= 6.

No. Of combinations scot can choose for his party

= 10*6*3

= 180

Scot can choose a total of 180 combinations for his party.
