Write the equation of a line that goes the through the point (4 , -2) and is parallel to the line y = 3x - 1/3.
nataly862011 [7]

Answer:

y = 3x - 14

Step-by-step explanation:

If a line is parallel to another, it will have the same slope

So, the line's slope will be 3

Plug in the given point and the slope into y = mx + b, and solve for b

y = mx + b

-2 = 3(4) + b

-2 = 12 + b

-14 = b

Plug in the slope and b into y = mx + b

y = 3x - 14

So, the equation is y = 3x - 14

Light in vacuum is incident on the surface of a slab of transparent material. In the vacuum the beam makes an angle of 43.8° wit
REY [17]

Answer:

Index of refraction of transparent is 1.48

Step-by-step explanation:

Snell's law states that;

n1(sinθ1) = n2(sinθ2)

Where;

n1 and n2 represent the indices of refraction for the two media, and θ1 and θ2 are the angles of incidence and refraction that the ray R makes with the normal.

In this question;

n1 = 1;

θ1 = 43.8°

θ2 = 19.3°

n2 is unknown.

Thus using Snell's law, we have;

1 x sin 43.8 = n2 x sin 19.3

n2 = (sin 43.8)/sin 19.3

n2 = 1.48
