\text{Hi there! :]}

\large\boxed{y = 8}

3y + 8 = 1/2y + 28\\\\\text{Subtract 8 from both sides:}\\\\3y + 8 - 8 = 1/2y + 28 - 8\\\\3y = 1/2y + 20\\\\\text{Subtract 1/2y from both sides:}\\\\3y - 1/2y = 1/2y - 1/2y+ 20\\ \\\text{Convert 3y to 6/2y to make subtracting easier:}\\5/2y = 20\\\\\text{Divide both sides by 5/2 (Multiply by reciprocal, or 2/5):}\\\\\\5/2y * 2/5 = 20 * 2/ 5\\\\y = 8

Csc x= -√2 for π≤x≤3π/2
love history [14]

Answer:

A

Step-by-step explanation:

We can write this as Sinx by "flipping" the -\sqrt{2}.

So we will have:  Sin(x)=-\frac{1}{\sqrt{2} }

From basic trigonometry, we know the value of  \frac{1}{\sqrt{2}}  of sine is of the angle \frac{\pi}{4}

<em>But when is sine negative? </em>Either in 3rd or 4th quadrant. But the answer has to be between 0 and  \frac{3\pi}{2}, <em>so we disregard 4th quadrant.</em>

<em />

<em>To get the angle in 3rd quadrant, we add π to the acute angle of the first quadrant (which is π/4 in our case).</em><u><em> Thus we have:</em></u>

\frac{\pi}{4}+\pi\\=\frac{\pi +4\pi}{4}\\=\frac{5\pi}{4}

A is the right answer.

Position to term rule of 2, 6, 10, 14, 18<br><br> multiply by _____ and subtract by _____
andreyandreev [35.5K]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the sequence

2, 6, 10, 14, 18

An arithmetic sequence has a constant difference and is defined as

\:a_n=a_1+\left(n-1\right)d

compute the differences of all the adjacent terms

6-2=4,\:\quad \:10-6=4,\:\quad \:14-10=4,\:\quad \:18-14=4

The difference between all the adjacent terms is the same.

Thus,

d=4

and

a_1=2

Therefore, the nth term is computed by:

a_n=4\left(n-1\right)+2

a_n=4n-2

Thus, position to term rule of 2, 6, 10, 14, 18  multiply by __4___ and subtract by __2__.

Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. The surrounding gas must not be saturated with the evaporating substance. When the molecules of the liquid collide, they transfer energy to each other based on how they collide with each other. Wikipedia
