Answer:

The perimeter of the rectangle is 60 units.

Explanation:

The perimeter of a rectangle is given by the equation P = 2L + 2W. With W = 12 units and L = 18 units, substituting the values in the equation above:

P = 2(18 units) + 2(12 units)

P = 36 units + 24 units

P = 60 units

The law of reflection establishes a definite relationship between the angle of incidence of a light ray striking the boundary be
sladkih [1.3K]

Answer:

The law of reflection states that the angle of incidence = the angle of reflection.

Explanation:

Reflection is the phenomenon that occurs when a ray of light hits the boundary between two media and it is reflected back into the first medium.

In such a situation, we call:

- angle of incidence: it is the angle between the direction of the incident ray and the normal to the surface

- angle of reflection: it is the angle between the direction of the reflected ray and the normal to the surface

There is a precise relationship between the angle of incidence and the angle of reflection. In fact, the Law of Reflection states that:

- The incident ray, the reflected ray and the normal to the surface all lie within the same plane

- The angle of reflection is equal to the angle of incidence

Phantasy [73]

Answer:

d

f(x) =  {x}^{2}  - 5x + 3 \\ f( - 1) =  {( - 1)}^{2}  - 5( - 1) + 3 \\  = 9

Am i correct? If not then which one
cupoosta [38]

Answer:

Yes, it's correct

Explanation:

Newton's second Law states that the acceleration of an object is proportional to the net force applied on it, according to the equation:

F=ma

where

F is the net force on the object

m is the mass of the object

a is the acceleration of the object

We can re-arrange the previous equation in order to solve explicitely for a, the acceleration, and we find:

F=ma\\\frac{F}{m}=\frac{ma}{m}\\\frac{F}{m}=a\\a=\frac{F}{m}

So, we see that the acceleration is proportional to the net force and inversely proportional to the mass of the object.
