Answer:
Step-by-step explanation:
so to go forward we input x and get out y, to go backwards ( the inverse) we plug in y and get out x , so just solve the equation for x
f(x) = 8x - 5
remember that f(x) = y
so,
y = 8x - 5
now solve for x
y+5 = 8x
(y+5) / 8 = x
then remember that we want to swap x and y ,
(x+5) / 8 = y
now y = [tex]f^{-1}[/tex](x), it's kinda confusing.
[tex]f^{-1}[/tex](x)= [tex]\frac{x+5}{8}[/tex]

The circumference of the ball will be 43.988cm and dividing the circumference by the diameter equals pie.
How to calculate the circumference?The object that's chosen in this scenario is a circular ball. The diameter of the ball is 14cm.
The circumference of the ball will be:
= 2πr
= 2 × 3.142 ×(14/2)
= 2 × 3.142 × 7
= 43.988cm
Dividing the circumference by the diameter will be:
= 43.988cm/14cm
= 3.142
The answer is close to pi.

About the Snowflakes
Last winter, I was watching the first snow of the year as it began. As I
was watching, I noticed an interesting pattern: The first minute, only
one snowflake fell. During each passing minute, the number of
snowflakes that fell was equal to the total on the ground plus one.
If this pattern continued for the whole snowstorm, how many
snowflakes fell during the 12th minute? During the 24th minute?
To get 100% on this assignment, you must write a variable
expression that represents how many snowflakes would fall during
the nth minute.

Using a geometric sequence, it is found that:
2048 flakes fell during the 12th minute.8,388,608 flakes fell during the 24th minute.What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
On the first minute, one flake fell. On the second minute, two flakes fell. On the third minute, four flakes fell(3 + 1). On the fourth minute, eight flakes fell(1 + 2 + 4 + 1). Hence the first term and the common ratio of the sequence are given by:
[tex]a_1 = 1, q = 2[/tex].
And the amount of flakes that fell in the minute n is:
[tex]a_n = 2^{n-1}[/tex]
In the 12th minute, the amount is given by:
[tex]a_{12} = 2^{12-1} = 2048[/tex]
In the 24th minute, the amount is given by:
[tex]a_{24} = 2^{24-1} = 8388608[/tex]

Which graft represent -3x+5y=-15
Answers
The graph of the function -3x+5y=-15 is a linear function we can draw it by finding the values of y for every value of x.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
-3x + 5y = -15
The above function shows a linear function we can write it as:
5y = 3x - 15
y = (3x - 15)/5
If x = 0, y = -3
x = 1, y = -2.4
x = 2, y = -1.8
x = -1, y = -3.6
x = -2, y = -4.2
Thus, the graph of the function -3x+5y=-15 is a linear function we can draw it by finding the values of y for every value of x.
