Factor the algebraic expression below in terms of a single trigonometric function.
sin 2x + sin x - 2 (2 points)

Answers

Answer 1

We know that sin (2x) = 2 sinxcosx.

So, sin (2x) + sin (x) - 2 becomes

2sin xcosx + sinx- 2.

Factor out sinx.

sinx(2cosx + 1 - 2)

sinx(2cosx - 1)

-x/6 + 6 = 32

Please help me! Thank you

(The -x/6 is a fraction in case you thought it was division)

Answers

Answer:

x = -156

Step-by-step explanation:

Solve for x by simplifying both sides of the equation, then isolating the variable.

Answer: x=−156

Step-by-step explanation: −x/6 +6=32

−1 /6 x+6−6=32−6

−1 /6 x=26

( 6 /−1 )( −1 /6 x)=( 6 /−1 )(26)

x=−156

Meg pounded a stake into the ground. When she attached a leash to both the stake and her dog’s collar, the dog could reach 9 feet from the stake in any direction. Using 3.14 for pi, what is the approximate area of the lawn, in square feet, the dog could reach from the stake.

Answers

The dog is able to run around in a circle with a radius of9 ft.

The area of a circle is A = pi r^2

A = (3.14) (9)^2

A= (3.14)(81)

A= 254.34 sq ft

y-3 = 2(-1+1)
y-3 = 2(0)
y-3=0
Add 3 to each side
y-3+3 = 0+3
y =3

Given g(x)=-2x+2, solve for x when g(x)=8

Answers

Answer:

x=±3. Explanation: g(x)=2x2−10 g(x)=8. ie 2x2−10=8 2x2=18 x2=9 x=±3.

Step-by-step explanation:

x = -3
To solve this, first set -2x + 2 = 8

Now you want to try to get x alone on one side so subtract 2 on both sides
-2x = 6

Finally divide both sides by -2 to find out what x is equal to

x =-3

To check if this is the right answer, plug -3 in for x in the original equation and see if it comes out as 8

-2(-3) + 2 = 8
6 + 2 = 8
8 = 8

Both sides are equal so -3 is the solution
