The correct option regarding whether the table represents a proportional relationship is:

The relationship is proportional because the ratio of m to k is constant.

<h3>What is a proportional relationship?</h3>

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

y = kx

In which k is the constant of proportionality.

In this problem, the ratio of m to km is given as follows:

k = 11/17.699 = 26/41.834 = 34/54.706 = 0.6215.

Since the values are equal, the correct option is:

The relationship is proportional because the ratio of m to k is constant.

1. Find the inverse of the one-to-one function f(x)= 6x-7 / 5

Elenna [48]

Rewrite it as y=6x-7/5

Flip the x and y
x=6y-7/5

Solve
5x=6y-7
5x+7=6y
5/6x+7/6=y

f^-1(x)=5/6x+7/6

Which of the following is a rational number?

Morgarella [4.7K]

Answer:

Square root of 100.

Step-by-step explanation:

Step-by-step explanation:

We can write 10 as a fraction 10/1, therefore, $\sqrt{}$ 100 is a rational number.

Part A : A rational no. between 5.2 and 5.5 is 5.3.

It is rational because it can be expressed in the form

p/q where p and q are integers and q is not equal to 0, which is 53/10

Part B: A rational no. between 5.2 and 5.5 is 5.29150262213

An irrational number between 5.2 and 5.5 is 5.29150262213. It is irrational because there is no pattern that repeats and it cant be written as a fraction of two whole numbers.
