Mathematics
1 answer:
frozen [14]3 years ago
4 0

Answer:

20

Step-by-step explanation:

Sonya has 5 sandwiches.she cuts each sandwich into fourths

1 sandwich divided into four parts

four parts = ¹/₄

1/¹/₄= 1x ⁴/₁= 4

so 1 sandwich divided into four parts is 4

so if 1 is divided into four parts is 4

5 will 4 x 5 = 20

so it means there will 20 of ¹/₄ sandwich

Tan(x+pi) + 2sin(x+pi)=0<br><br>can you help prove this and make the left side equal the right?
vladimir1956 [14]

This is not an identity but an equation. You're supposed to find the values of x for which this is true. It is *not* true for all values of x.

To see why:

\tan x has period \pi, which means \tan(x+\pi)=\tan x.

The angle sum identity for \sin x says that

\sin(x+\pi)=\sin x\cos \pi+\cos x\sin\pi=-\sin x

So

\tan(x+\pi)+2\sin(x+\pi)=\tan x-2\sin x

By definition of \tan x,

\tan x=\dfrac{\sin x}{\cos x}

and so

\tan x-2\sin x=\sin x\left(\dfrac1{\cos x}-2\right)

which is only 0 if either \sin x=0 (which only happens for certain values of x) or \dfrac1{\cos x}-2=0\implies\cos x=\dfrac12 (which also only happens for certain values of x). It's these values of x you want to find.

\sin x=0 whenever x is a multiple of \pi, i.e. x=n\pi for any integer n.

If 0\le x, then \cos x=\dfrac12 is true for x=\dfrac\pi3 and x=\dfrac{5\pi}3. Then to account for all other possible values, we add a multiple of 2\pi, so that x=\dfrac\pi3+2n\pi or x=\dfrac{5\pi}3+2n\pi for integers n.

The distance between points (3,7) and (x1-y1) is the square root of (x1-3)2+(y1-7)2
galben [10]

Answer:

True

Step-by-step explanation:

In analytical geometry, you can find the distance between two points situated on the same plane using the distance formula. The equation is

d = √[(x2-x1)^2+(y2-y1)^2]

This can be applied by first applying which is point 1 or point 2. Technically, it does not matter which is which, as long as you are consistent in pairing of the x,y coordinates. In this case, point 1 is (3,7) and point 2 is (x1,y1). Therefore, when you substitute the values, the distance would be 

d = √[(x1-3)^2+(y1-7)^2]

The statement is TRUE.

I hope this helped. I am not sure it did. But I hope it helped you. I hope you get the question right. And I am sorry if you get the question wrong.
