A is the closest I got. My answer was 32.665 using thousandth place. I found the perimeter by adding up the lengths. I found all of the lengths by using pathat oran theorem.

NISA [10]

Answer:

12

Well, to make things easier, we can first note that 24/4 is equal to 6. This helps because integers are easier to work with compared to fractions. Next, multiplying 2 by 6, we get 12.

Prove that sin^4x + cos^4x= sinxcosx
yKpoI14uk [10]

Answer:

(the relation you wrote is not correct, there may be something missing, so I will simplify the initial expression)

Here we have the equation:

sin^4(x) + cos^4(x)

We can rewrite this as:

(sin^2(x))^2 + (cos^2(x))^2

Now we can add and subtract cos^2(x)*sin^2(x) to get:

(sin^2(x))^2 + (cos^2(x))^2 + 2*cos^2(x)*sin^2(x) - 2*cos^2(x)*sin^2(x)

We can complete squares to get:

(cos^2(x) + sin^2(x))^2 - 2*cos(x)^2*sin(x)^2

and we know that:

cos^2(x) + sin^2(x) = 1

then:

1 - 2*sin(x)^2*cos(x)^2

This is the closest expression to what you wrote.

We also know that:

sin(x)*cos(x) = (1/2)*sin(2*x)

If we replace that, we get:

1 - \frac{sin^2(2*x)}{2}

Then the simplification is:

cos^4(x) + sin^4(x)  = 1 - \frac{sin^2(2*x)}{2}

Enter the value of n so that the expression (y + 2) + (3y - 5) is equivalent to (ny- 3)
matrenka [14]

Answer: n = 4

Step-by-step explanation: you combine the like variables which turns it into

(4y - 3)

(4y - 3) is <em>another</em> way of saying ((4 x y) - 3)

So the 4 is turned into n making it (ny - 3)
