Complete the identity. sin4x - cos4x = ?
Katyanochek1 [597]
Since sin(2x)=2sinxcosx, we can plug that in to get sin(4x)=2sin(2x)cos(2x)=2*2sinxcosxcos(2x)=4sinxcosxcos(2x). Since cos(2x) = cos^2x-sin^2x, we plug that in. In addition, cos4x=cos^2(2x)-sin^2(2x). Next, since cos^2x=(1+cos(2x))/2 and sin^2x= (1-cos(2x))/2, we plug those in to end up with 4sinxcosxcos(2x)-((1+cos(2x))/2-(1-cos(2x))/2)
=4sinxcosxcos(2x)-(2cos(2x)/2)=4sinxcosxcos(2x)-cos(2x)
=cos(2x)*(4sinxcosx-1). Since sinxcosx=sin(2x), we plug that back in to end up with cos(2x)*(4sin(2x)-1)

William is setting up for folding chairs for a meeting he arranges the chairs and seven rows of the same link he has three chair
DiKsa [7]

Answer:

William has a total of 66 chairs.

Step-by-step explanation:

Let the number of chairs in each row be 'x'.

Also let the Total number of chairs be 'y'.

Given:

If he arranges the chairs in seven rows of the same length he has three chairs left

Number of rows = 7

Number of chairs left = 3

Now we can say that;

Total number of chairs will be equal to number of chairs in each row multiplied by Number of rows plus Number of chairs left.

framing in equation form we get;

y=7x+3

Also Given:

If he arranges the chairs in five rows of the same length he has 21 chairs left

Number of rows = 5

Number of chairs left = 21

Now we can say that;

Total number of chairs will be equal to number of chairs in each row multiplied by Number of rows plus Number of chairs left.

framing in equation form we get;

y=5x+21

Now we know that Total number of chairs are same.

Hence we can say that both the equations are equal.

7x+3=5x+21

Combining like terms we get;

7x-5x=21-3\\\\2x= 18

Dividing both side by 2 we get;

\frac{2x}{2}=\frac{18}{2}\\\\x=9

So we can that there are 9 chairs in each row.

Now to find the total number of chairs he has we will substitute value of x in any of the equation we get;

y =7x+3\\\\y=7\times9+3\\\\y=63+3 =66

Hence William has a total of 66 chairs.
