EASY QUESTION. HELP NEED PLZ.

Mathematics
1 answer:
Setler79 [48]3 years ago
3 0

Answer:

1: 30 degrees

Step-by-step explanation:

In Physics, we have the law of reflection. This law states that when light rays hit the smooth surface of mirror or any smooth polished surface, the angle of incidence is equivalent to the angle of reflection.

Mathematically:

Angle of incidence = Angle of reflection

From the above question, the angle of incidence is on a smooth plane mirror = 30°

Since:

Angle of incidence = Angle of reflection

30° = 30°

Therefore, based on the law of reflection, the Angle of reflection = 30°

Answer and explanation please
Alisiya [41]
Probability=number of specific outcomes/number of total possible outcomes...there are 16 pieces in all.

So the probability of picking a king is 1/16

And the probability of picking a pawn is 8/16=1/2

The probability of these two events happening in a row is:

P(k)*P(p)=(1/16)(1/2)=1/32

What is an equation of the line that passes through the point (2,-5) and is parallel
Blababa [14]

Answer:

y = -6x + 7

Step-by-step explanation:

In this question, we need to find the equation of a line with the given information.

We know that the line passes through (2, -5).

We also know that the line is parallel to the line 6x + y = 6, which means that it has to have the same slope.

To make it simpler to understand, we can change the equation into slope format:

y = -6x + 6

This means that our new line should have a slope of -6.

With the information above, we can plug in our new values to get the y-intercept of our equations, since we don't have that information.

Plug in your slope and coordinates to the y = mx + b equation and solve for b:

-5 = -6(2) + b

-5 = -12 + b

Add 12 to both sides.

7 = b

Our y-intercept would be b.

Now, we can plug in all our information to get our new equation:

y = -6x + 7

Your answer would be y = -6x + 7
