Om you get the slope by putting the points in the equation y2 - y1/ x2 - x1 

ok when you plug them in it should look like this

8 + 11/ 10 + 17 

19/27

that would be you rnaswer becuase it can't be simplified no more hope this helped

A beam of light from a monochromatic laser shines into a piece of glass. The glass has thickness L and index of refraction n=1.5
boyakko [2]

Additional information to complete the question:

How long does it take for a short pulse of light to travel from one end of the glass to the other?

Express your answer in terms of some or all of the variables f and L. Use the numeric value given for n in the introduction.

T = ___________ s

Answer:

 T = \frac{15}{f}

Step-by-step explanation:

Given:

Thickness og glass = L

Index of refraction n=1.5

Frequency = f

Wavelength = \frac{L}{10}

λ(air) = \frac{L}{10}

λ(glass) = λ(air) / n

             = \frac{\frac{L}{10}}{1.5}

             = \frac{L}{10} * \frac{1}{1.5}

             = \frac{L}{15}

V(glass) = fλ(glass)

              = f * \frac{L}{15}

          T = \frac{L}{V_{glass}} = \frac{15}{f}

What is the area? (IXL)
Zina [86]

Answer:

45 square meters

Step-by-step explanation:

we know that

The area of trapezoid is equal to

A=\frac{1}{2}(b1+b2)h

where

b1 and b2 are the parallel bases

h is the height of trapezoid (perpendicular distance between the parallel bases)

we have

b1=6\ m\\b2=9\ m\\h=6\ m

substitute

A=\frac{1}{2}(6+9)6

A=45\ m^2

Solve equations: 3|x+4|=6<br><br> | = absolute value
Anestetic [448]

Absolute values are a way of finding a distant from zero, which means there will be 2 answers; one will be positive, and the other will be negative.

|<em>3x - 4</em>| = 5<em>and</em> |3<em>x - 4</em> = a^5 Because you need 2 answers, you have to make 5 positive and negative.

Another way to write this equation would be...

5=|3x-4|=—5

Now lets continue...

5=3x-4=—5

Add 4 to both sides...

9=3x=—1

Now divide by 3...

3=x= -1/3

So the solution is...

X={-1/3  3}
