Answer:
{-11,8,13}
Step-by-step explanation:
The domain is the input values (or x)
The range is the output values (or y)
The range is (-11,8,13)
Answer:
24
Step-by-step explanation:
use Pythagoras theorem
a^2 + b^2 = c^2
18^2+b^2=30^2
b^2 = 30^2 - 18^2
b = √576 =24

<h2>
Explanation:</h2>
In this exercise, we have the following point:

Let's assume that y varies directly as x, so this implies we can writ y as the product of x and some non-zero real constant k. In a mathematical language:

As you can see, this is the equation of a line whose slope is k and passes through the origin. Therefore, the slope of the line is the constant of proportionality we are looking for:

Answer:
C ≈ 11.71 cm
Step-by-step explanation:
using the ratio arc AC : circumference C = angle at centre of sector : 360°
=
, that is
=
( cross- multiply )
123 × C = 4 × 360 = 1440 ( divide both sides by 123 )
C =
≈ 11.71 cm ( to the nearest hundredth )
x represents the total sales and y represents the total amount of money that Gary earns.
Gary's monthly salary = 1500
His commission = 10% of his sales
= 
= 0.1x
So, total amount of money Gary earns is y = 0.1x + 1500.
