Answer:
<h2>89.5°</h2>Step-by-step explanation:
Using the vector formula
|u| = magnitude of vector u
|v| = magnitude of vector v
u.v is the dot product of vector u and v
Given |u| = 88, |v| = 99 and u.v = 77, to get we will substitute the given values into the equation above;
Answer:
A) a vertical line does not represent a function.
Step-by-step explanation:
For a relation to be a function for each value of there must be only one value of
. In other words a function is one in which each value in the domain set corresponds to only one value in the range set.
Let us check for this condition in the give choices:
A) a vertical line
A vertical line is given as which meas it is parallel to y-axis and has infinite number of
values for a single
value.
So, its Not a function
B)
For the given equation, on plugging in some value will give a single
value.
So, its a Function
C) a horizontal line
A horizontal line is given as which meas it is parallel to x-axis and has infinite number of
values giving a single
value.
So, its a Function
D) {(1, 7), (3,7), (5, 7), (7,7)}
For the given set for different valuesthere is only one
value.
So, its a Function
