Use the squared identities to simplify 2sin^2 x cos^2 x

guapka [62]

The given question is

$2sin^2 x cos^2 x$

Multiplying and divide by 2

$\frac{4sin^2 x cos^2 x}{2} =\frac{(2 sinx cos x})^2{2}=\frac{sin^2(2x)}{2}$

Again multiplying and dividing by 2

$\frac{2sin^2(2x)}{4}$

And

$2 sin^2(2x)=1-cos(4x)$

So we will get

$\frac{1-cos(4x)}{4}$

Correct option is D

Answer:

Step-by-step explanation:

From a given point outside the circle, the two tangents to the circle are the same length. This means: JB = JA, CL = AL, and BK = CK.

The perimeter is the sum of all these segments, so is ...

P = JB +JA +CL +AL +BK +CK = 8 +8 +13 +13 +11 +11

= 2(8 +13 +11) = 2(32)

P = 64

The perimeter of the triangle is 64 units.
