1 answer:

7 0

The first trigonometric expression cot x and sin x in terms of the second expression is one over tan x and one over cosec x.

<h3>What is trigonometry?</h3>

Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.

Write the first trigonometric expression in terms of the second expression.

The cotangent can be written as

$\cot x= \dfrac{1}{\tan x}$

And the sine can be written as

$\sin x = \dfrac{1}{\csc x}$

Answer:

Part A -> Function

Part B -> Function

Step-by-step explanation:

Concept

A relationship is a function only if there's a single y value corresponding to an x value. It can have the same y value for different x values but it must not have multiply y values for a single x value.

Below is an example

Function Not a Function

x y x y

1 5 1 5

2 6 2 7

3 5 1 6

Part A

Looking at the given graph, we see that the relationship has a single y value corresponding to an x value and so it is a function.

Part B

If there was the same number of bacteria for two consecutive hours it would mean the same y value for different x values. So, it would still remain a function.

Answer:

81/15

Step-by-step explanation:

14/3 would become 70/15 and 11/5 would become 33/15 and 70+33 is 103, so 103/5. 103/15 - 22/15 = 81/15.

The ratio of two side lengths for the triangle is given. What is the value of “q” AB:BC is 3:4

Vera_Pavlovna [14]

Answer:

$q=8.5$

Step-by-step explanation:

The ratio of the side lengths (AB) and (BC) is given. One is also given an expression for the side lengths of each of these sides. Set up a proportion to describe this scenario, then solve using cross products;

$\frac{AB}{BC}=\frac{3}{4}$
