If the light ray hits a mirror at a 40 degree angle what angle will the ray of light be reflected

Answers

Answer 1
Answer:

The angle will also be 40 degrees because the reflected ray has the same angle as the incident ray.

What is the reflection of light?

When light rays reflect off a surface, migrate from one transparent medium to another, or travel through a medium whose composition is constantly changing, they change direction.

The angle of the reflected ray is equal to the angle of the incident beam when reflected off a flat surface, according to the law of reflection. (By convention, all angles in geometrical optics are measured with respect to the surface's normal, i.e. a line perpendicular to the surface.)

The reflected ray always falls in the plane specified by the incident light and the surface normal. To comprehend the pictures formed by planar and curved mirrors, the law of reflection can be applied.

As per the question, the light ray hits a mirror at a 40-degree angle.

Thus, the angle will also be 40 degrees because the reflected ray has the same angle as the incident ray.

Pls help Zoey is trying to write an equation in slope intercept form. She knows slope intercept form is y=mx+b. She is given the slope is 3 and the y intercept is 10. When she plugs it in she gets 10=3x+b. What mistake did zoey make and how can she fix it?

Answers

Answer:

the mistake that zoey had made while writing the equation was putting the y-intercept in the wrong place.in the slope intercept from the equation is y=mx+b.y is the product or the line, m is the slope, b is the y-intercept, the actual equation should be y=3x+10,instead what zoey had which was 10=3x+b. she guessd by pairing the y-intercept with y instead of b.

Answers

(1/2)x² - (5/4)x - 3 = 0

0.5x² - 1.25x - 3 = 0

Comparing to the quadratic function, ax² + bx + c = 0,    
a = 0.5,  b = -1.2,  c = -3.

Sum of roots = -b/a   =    -(-1.25)/0.5 =    1.25/0.5 = 2.5

2.5 = 5/2  Option (a)
A)5/2 is the answer.

Can you help? Thanks!​

Answer:

(7, 2).

Step-by-step explanation:

The median from A intersects BC at it's midpoint.

To find the midpoint of BC:

This is (x1, y1) where x1 = (sum of the x_values of B and C) / 2)  and where y1

= (sum of the y_values of B and C) / 2)

This is (2+12)/2,  (1 + 3)/2

= (7, 2).
