Answer: There were many effects of military development after WWII in Europe. One of these was that it allowed for European superpowers to more easily conquer third-world nations and countries which did not have the same military tech. Another, more specific example is the collapse of the Ottoman empire. One of the main reasons for the collapse of this Muslim caliphate was that it refused to use modern weaponry and was thus crushed in many battles due to its inferior military.

What are the possible steps involved in solving the equation shown? Select three options.

e-lub [12.9K]

Answer:

Option B, C and D are correct choices.

Step-by-step explanation:

We have been given an equation $3.5+1.2(6.3-7x)=9.38$ . We are asked to choose the steps that are involved in solving the equation.

Let us solve the equation.

Using distributive property $a(b+c)=ab+ac$ , we will distribute 1.2 to 6.3 and $-7x$ .

$3.5+1.2*6.3-1.2*7x=9.38$

$3.5+7.56-8.4x=9.38$

Therefore, option B is the correct choice.

Now, we will combine like terms.

$11.06-8.4x=9.38$

Therefore, option C is the correct choice.

Now, we will subtract 11.06 from both sides of our equation.

$11.06-11.06-8.4x=9.38-11.06$

$-8.4x=-1.68$

Therefore, option D is the correct choice.

Now, to solve for x, we need to divide both sides of our equation by $-8.4$

$\frac{-8.4x}{-8.4}=\frac{-1.68}{-8.4}$

$x=0.2$

2sin(4x)+6=5

a_sh-v [17]

Let's solve the sine equation.

1. Express sine function in the left side of equation:

$2\sin (4x)+6=5,\\ 2\sin (4x)=5-6,\\ 2\sin (4x)=-1,\\ \\ \sin (4x)=-\dfrac{1}{2}$ .

2. Use the genereal solution to get the solution of your equation:

$4x=(-1)^n\arcsin \left(-\dfrac{1}{2}\right) +2\pi n$ , where $n\in Z$ .

3. Find $\arcsin \left(-\dfrac{1}{2}\right)$ :

$\arcsin \left(-\dfrac{1}{2}\right)=-\dfrac{\pi}{3}$ .

4. Substitute part 3 into part 2 and express x:

$4x=(-1)^n \left(-\dfrac{\pi}{3}\right) +2\pi n$ , where $n\in Z,$

$x=(-1)^{n+1}\cdot \dfrac{\pi}{12}+\dfrac{\pi n}{2}$ , where $n\in Z$ .

5. Solutions of your equation are:

$x=(-1)^{n+1}\cdot \dfrac{\pi}{12}+\dfrac{\pi n}{2}$ , where $n\in Z$ .
