The length of AB after dilation is 3/5cm.
what is scale factor?The size by which the shape is enlarged or reduced is called as its scale factor.
Scale factor is defined as the number or the conversion factor which is used to change the size of a figure without changing its shape.
It is used to increase or decrease the size of an object.
The scale factor can be calculated if the dimensions of the original figure and the dimensions of the dilated (increased or decreased) figure are known.
For example, a rectangle has a length of 5 units and a width of 2 units. Now, if we increase the size of this rectangle by a scale factor of 2, the sides will become 10 units and 4 units, respectively. Hence, we can use the scale factor to get the dimensions of the changed figures.
Given:
Length of AB = 3 cm
scale factor = 1/5
As, we know
scale factor = change in length / Actual length
1/5 = Change in length / 3
Change in length = 3/5
Hence, the length of AB after dilation is 3/5 cm

Inverse of f(x)=3x^3+8
The inverse of f(x) = 3x³ + 8 is [tex]\sqrt[3]{\frac{x-8}{3}}[/tex].
What is an inverse function ?Two functions f(x) and g(x) are inverse functions if (fog)x = x and (gof)x = x.When we combine two functions by means of arithmetic operations we call them composite function.
According to the given question we have to determine the inverse of f(x) = 3x³ + 8.
This can be written as
y = 3x³ + 8.
Now we'll switch x and y meaning everywhere there is x we'll replace with y and vice versa.
x = 3y³ + 8.
Now we'll solve for y.
3y³ = x - 8.
y³ = (x - 8)/3.
y = [tex]\sqrt[3]{\frac{x-8}{3}}[/tex].
f(x⁻¹) =[tex]\sqrt[3]{\frac{x-8}{3}}[/tex].

On factorizing 3y⁻⁴ + y⁻⁵ with the given factor y⁻⁵ we get y⁻⁵(3y + 1 ).
Factorization of the polynomial refers to the process of expressing the polynomial as a product of two or more factors.
For Example ; the factors of x²-16 can be written as (x+4)(x-4).
In the given question
(3y⁻⁴ + y⁻⁵)
the common factor y⁻⁵ is given
we have to factorize using the common factor .
taking y⁻⁵ common from both the terms we get
= y⁻⁵(3y⁻⁴/y⁻⁵ + 1 )
=y⁻⁵(3y⁻⁴⁺⁵ + 1 )
=y⁻⁵(3y¹ + 1 )
=y⁻⁵(3y + 1 )
Therefore , On factorizing 3y⁻⁴ + y⁻⁵ with the given factor y⁻⁵ we get y⁻⁵(3y + 1 ).

Step-by-step explanation:
when we consider what is all truly equal in both sides of the equal signs, we get a rather simple situation, because we can eliminate the equal parts on both sides. remember, addition has the associative property.
that gives us
3 = 2/3 m
9 = 2m
m = 9/2
