Function or not a function?

Answers

Answer:

Not a function

Step-by-step explanation:

To answer this, we first need to know what a function actually is: A function is a relation between 2 sets which relates the element of the first set to only one element of the second set.

We can see in the provided image that the value -9 is related to 2 values of the second set, hence it is NOT a set.

Another way to think about it is that a function takes an input and gives only one output (where the left set is the input and the right set is the output). Since -9 gives 2 outputs from the given relation, it cannot be a function.

Step-by-step explanation:

Divide both the numerator and denominator by the GCD

75 ÷ 25

125 ÷ 25 if im wrong sorry

The ratio of 75m : 125cm in its simplest form is 60 : 1.

What are ratio and proportion?

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, Two similar quantities.

We know 75m = 75×100 = 7500 cm.

Therefore, The ratio between them is,

7500 : 125.

1500 : 25.

300 : 5.

60 : 1.

Calculate the side lengths a and b to two decimal places.

Answers

Answer:

Below in bold.

Step-by-step explanation:

m < C = 180 - 43 - 115 = 22 degrees.

Using the Sine Rule:

6 / sin 22 = a / sin 43

a sin 22 = 6 sin 43

a = 6 sin 43 / sin 22

a = 10.92 to 2 DP's.

Applying the same rule  to calculate b:

6 / sin 22 = b / sin 115

b = 6 sin 115 / sin 22

b = 14.52 to 2 DP's.
