The number of entries in the domain and range of a function can be different. Some inputs in the domain may have the same output in the range, or some outputs in the range may have no corresponding inputs in the domain.
In a function, the number of entries in the domain and range can be different. This happens when there are multiple inputs that map to the same output or when there are outputs with no corresponding inputs.
For example, consider the function f(x) = . The domain can be any real number, but the range is only non-negative real numbers (including zero). So, there are more entries in the domain than in the range.
When this is the case, it means that some inputs in the domain have the same output in the range, or some outputs in the range have no corresponding inputs in the domain.

Answer: The scale factor of the dilation =3
Step-by-step explanation:
We know that if we transform point (x,y) by using dilation with scale factor k then the coordinate of the image will be (kx,ky).
Given: under a dilation, the point (2, 6) is moved to (6, 18)
Here (x,y)=(2,6) and (kx,ky)=(6,18)
Hence, the scale factor for the given dilation= 3.

The value of cos θ is,
⇒ cos θ = 0.6
The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Now, We can Draw a line from point ( 0.6, 0.8 ) to the X - axis, forming a right triangle with hypotenuse = r = 1 , adjacent = 0.6, opposite = 0.8
Hence, We can formulate;
⇒ cos θ = 0.6 / 1
⇒ θ = cos ⁻¹ 0.6
⇒ θ = 53.13°
Thus, The value of cos θ is,
⇒ cos θ = 0.6

Answer:
Width, b = 2.14 cm
Step-by-step explanation:
Given that,
The area of the rectangle = 22.5 cm
Length, l = 10.5
Width, b = (x+0.6)cm
We need to find the width of the rectangle. The area of a rectangle is given by :
A = lb
So,
22.5 = 10.5(x+0.6)
22.5 =10.5x+6.3
22.5-6.3 = 10.5 x
16.2 = 10.5x
x = 16.2/10.5
x = 1.54 cm
Width, b = (1.54+0.6)cm
= 2.14 cm
So, the width of the rectangle is 2.14 cm.
