Answer:
<u>Trigonometric ratios</u>
where:
is the angle- O is the side opposite the angle
- A is the side adjacent the angle
- H is the hypotenuse (the side opposite the right angle)
To find sin x and cos y, we must first find the length of the <u>hypotenuse</u> (PO) of the given right triangle.
To do this, use <u>Pythagoras' Theorem:</u>
Given:
Using the found value of the hypotenuse and the trig ratios quoted above:
Therefore, 
Answer:
Selling price= $13
Step-by-step explanation:
Giving the following information:
The cost of your product is $10, and you are planning a 30% mark-up.
<u>The price of the product is calculated by adding to the manufacturing costs a predetermined percentage.</u>
Selling price= 10*1.3
Selling price= $13
The formula that shows the relationship between the distance, rate and time is t = d/r and t = 5.
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depend on any other variable for its value while a dependent variable is a variable that depends on other variable.
Given that:
d = rt
Hence:
t = d/r
For d = 40, r = 8:
t = 40 / 8
t = 5
The formula that shows the relationship between the distance, rate and time is t = d/r and t = 5.
