Answer:

x= -5

y= -2

Step-by-step explanation:

3x + 4y = -23

3(3y + 1) + 4y = -23

9y + 3 + 4y = -23

13y = -26

y= -2

x= 3 * y + 1

x = 3 * (-2) + 1

x = -5

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 circumference of the circle with a radius of 3.22 Round to the nearest tenth.
myrzilka [38]
To calculate the circumference multiply the radius by 2 to get the diameter. Multiply the result by π, or 3.14 for an estimation.

3.22x 2 = 6.44

6.44x π= 20.23185668911827

rounded to the nearest ten: 20.2
