How do I complete this identity? sin(2θ) sin(4θ) cos(2θ) cos(4θ) = ?

egoroff_w [7]

Answer:

sin(20) sin(40) cos(40) cos(20)
[sin(20)*cos(20)]*[sin(40)*cos(40)]
[sin(2*20)/2]*[sin(2*40)/2]
[sin(40)*sin(80)]/2

Plz hurry and answer this correctly!!!

In-s [12.5K]

Answer:

$\large\boxed{C)\ \dfrac{8}{5}\pi\ cm}$

Step-by-step explanation:

The formula of an area of a circle:

$A_O=\pi r^2$

The formula of a perimeter of a circle:

$P_O=2\pi r$

r - radius

We have the area of a circle

$A_O=\dfrac{16}{25}\pi\ cm^2$

Substitute:

$\pi r^2=\dfrac{16}{25}\pi$ <em>divdie both sides by π</em>

$r^2=\dfrac{16}{25}\to r=\sqrt{\dfrac{16}{25}}\\\\r=\dfrac{\sqrt{16}}{\sqrt{25}}\\\\r=\dfrac{4}{5}\ cm$

Calculate the perimeter:

$P_O=2\pi\left(\dfrac{4}{5}\right)=\dfrac{8}{5}\pi$

Maximum value of x3y3 + 3 x*y when x+y = 8.

Galina-37 [17]

Answer:

The answer is 4144.

Step-by-step explanation:

We have to find the maximum value of f(x)= $x^{3}y^{3}+3xy$ when $x+y=8$

We can write $x+y=8$ as $y=8-x$

Substituting the value of y

$f(x)=x^{3}(8-x)^{3} +3x(8-x)$

= $3x^{2}(8-x)^{2}[-x+8-x]+3[-x+8-x]$

= $3(8-2x)[x^{2}(8-x)^{2}+1]$

For maximum, we will equate the equation to 0.

And we get,

$8-2x=0$ => x = 4

And as $y=8-x$

$y =8-4= 4$ > y = 4

So, we will put these values in equation to get maximum value.

= $x^{3}y^{3}+3xy$

= $xy(x^{2}y^{2}+3)$

= $4\times4((16\times16) +3)$

= $16(259)$ = 4144

Korolek [52]

Answer:

y= 3x +2

Step-by-step explanation:

-10x-30y = 6

-30y = 10x +6

y = -1/3x - 1/5

m = -1/3 perpendicular slope would be 3

2x+9y = 18

2(0) +9y = 18

y = 2 = y intercept

y = 3x +2
