Answer:
cos 90°
Step-by-step explanation:
(cos 60°)(cos 30°) − (sin 60°)(sin 30°)
= cos ( 60° + 30°)
= cos 90°
Answer:
Option B.
Step-by-step explanation:
From the given table it is clear that the linear function passing through the points (-14,-18) and (-10,-12).
The slope of a linear function is
The given line passing through the points (-14,-18) and (-10,-12), so the slope of the line is
The slope of the required line is .
Therefore, the correct option is B.
Answer: No! This is not a function!
Step-by-step explanation:
Functions. Terms. Domain - The set of all inputs of a relation or function. Function - A relation in which each input has only one output. Often denoted f (x). Horizontal Line Test - If every horizontal line you can draw passes through only 1 point, x is a function of y.
I started at (-2, 0) but you can start at any point on the graph that goes through the corner of the square (if that makes sense) like a point on the graph. From one point to the next, you go down one and one to the right, therefore the slope is a -1
