3 sin 0 = 3 cos 20<br> what is the solution set?<br>

lutik1710 [3]

Answer:

Step-by-step explanation:

3 sinθ=3 cos 2θ

sin θ=cos 2θ

sinθ=1-2sin² θ

2sin²θ+sin θ-1=0

2sin²θ+2sinθ-sinθ-1=0

2sin θ(sin θ+1)-1(sin θ+1)=0

(sin θ+1)(2 sin θ-1)=0

sin θ=-1=-sin 90=sin (180+90)

θ=270

or sin θ=1/2=sin 30,sin (180-30)

θ=30,150

solution set is {30,150,270}

I really need help been on this problem for like 20 min

ycow [4]

Start with x:
Since x and 57º make a straight line, x+57 = 180 (because a line is 180º). This says x=123º

Now for y:
Because lines m and n are parallel, y and 57º are alternate interior angles and have the same measure. y=57º

Finish with z:
Since y and z make a straight line, can you finish that one from here?

Suppose you invest $78 a month in an annuity that earns a 2.8% APR, compounded monthly. How much money will you have in this acc

Alecsey [184]

Answer:

$87.23.

Step-by-step explanation:

We are asked to find the amount after 4 years compounded monthly at the rate of 2.8% APR.

We will use compound interest formula to solve our given problem.

$A=P(1+\frac{r}{n})^nT$ , where,
