-64=(2cos(pi/2)+2i sin(pi/2))^n..... n=??

zvonat [6]

Answer:

The real solution is $n=6$ .

Step-by-step explanation:

$\cos(\frac{\pi}{2})=0$ while $\sin(\frac{\pi}{2})=1$

So the equation becomes:

$-64=(2(0)+2i(1))^n$

$-64=(0+2i)^n$

$-64=(2i)^n$

We know that $2^6=64$ . So let's see what $n=6$ gives us:

$(2i)^6=64i^6=64i^4i^2=64(1)(-1)=-64$ .

$-64$ is the result we wanted.

$n=6$ is therefore a solution.

What is the justification for step 2 in the solution process?

gulaghasi [49]

Answer: OPTION B.

Step-by-step explanation:

Given the following equation:

$10x - 25 - 3x = 4x- 1$

These are the steps to solve it:

Step 1

Add like terms on the left side of the equation:

$7x -25= 4x - 1$

Step 2

Apply Addition property of equality, which states that: $If\ a=b\ then\ a+c=b+c$

Then, we can add 25 to both sides of the equation:

$7x -25+(25)= 4x - 1+(25)\\\\7x=4x+24$

Step 3

Applying the Subtraction property of equality, we can subtract $4x$ from both sides:

$7x-4x=4x+24-(4x)\\\\3x=24$

Step 4

Applying the Division property of equality, we can both sides of the equation by 3. Then:

$\frac{3x}{3}=\frac{24}{3}\\\\x=8$

Paha777 [63]

I think the answer is 12/20 or 3/5 because out of the 20 marbles you are drawing 4 orange and 8 blue and replacing it. So 8+4=12 and there are 20
