Which of the following are identities? check all that apply.
Feliz [49]

Answer: (a), (b), (c), and (d)

Step-by-step explanation:

Check the options

(a)\\\Rightarrow [\sin x+\cos x]^2=\sin ^2x+\cos ^2x+2\sin x\cos x\\\Rightarrow [\sin x+\cos x]^2=1+2\sin x\cos x\\\Rightarrow \Rightarrow [\sin x+\cos x]^2=1+\sin 2x

(b)\\\Rightarrow \sin (6x)=\sin 2(3x)\\\Rightarrow \sin 2(3x)=2\sin (3x)\cos (3x)

(c)\\\Rightarrow \dfrac{\sin 3x}{\sin x\cos x}=\dfrac{3\sin x-4\sin ^3x}{\sin x\cos x}\\\\\Rightarrow 3\sec x-4\sin ^2x\sec x\\\Rightarrow 3\sec x-4[1-\cos ^2x]\sec x\\\Rightarrow  3\sec x-4\sec x+4\cos x\\\Rightarrow 4\cos x-\sec x

(d)\\\Rightarrow \dfrac{\sin 3x-\sin x}{\cos 3x+\cos x}=\dfrac{2\cos [\frac{3x+x}{2}] \sin [\frac{3x-x}{2}]}{2\cos [\frac{3x+x}{2}]\cos [\frac{3x-x}{2}]}\\\\\Rightarrow \dfrac{2\cos 2x\sin x}{2\cos 2x\cos x}=\dfrac{\sin x}{\cos x}\\\\\Rightarrow \tan x

Thus, all the identities are correct.

PLEASE HELP PLEASE PLEASE
Aleks [24]

Answer:

(2, 4)

Step-by-step explanation:

When plotting points you need to do the x first then the y,

To help you remember the order use the saying OVER AND UP.

For the x-axis is the line going from SIDE to SIDE,

For the y-axis is the line going UP to DOWN,

The Radio City Music Hall x value is 2 and the y value 4.

Therefore your coordinates/ordered pair is (2, 4).

at a restaurant the ratio of kids meals sold to adults meal was 5:4. if there were 20 kids meals sold, what is the combined amou
seraphim [82]
I would set up a proportion:

\frac{20}{x}=\frac{5}{4}

The proportion basically says, "if there are 5 kids meals for every 4 adult meals, that means 20 kids meals would mean x adult meals."  Just cross multiply and then solve for x:

\frac{20}{x}=\frac{5}{4}\\5x=80\\x=16

That means there are 20 kids meals sold and 16 adult meals sold, so the result is:

36 meals in total.
