<u>Answer:</u>
Value of cosθ is ±√7/3 .
<u>Step-by-step explanation:</u>
According to the Question , value of :

And , we know the identity of sine and cosine as ,
<u>Using</u><u> </u><u>,</u><u> </u><u>this</u><u> </u><u>ident</u><u>ity</u><u> </u><u>we</u><u> </u><u>have</u><u> </u><u>;</u><u> </u>

Now , here since θ is in 2nd quadrant and in 2nd quadrant cos is negative . Hence ,the value of cos will be :
Answer:
is linearly dependent set.
Step-by-step explanation:
Given:
is a linearly dependent set in set of real numbers R
To show: the set
is linearly dependent.
Solution:
If
is a set of linearly dependent vectors then there exists atleast one
such that 
Consider 
A linear transformation T: U→V satisfies the following properties:
1. 
2. 
Here,
∈ U
As T is a linear transformation,

As
is a linearly dependent set,
for some 
So, for some 

Therefore, set
is linearly dependent.
The formula of g(x) is g(x) = -0.8x - 1.6
<h3>How to determine the
formula of g(x)?</h3>
The equation is given as:
-4x - 6 = 5y + 2
Subtract 2 from both sides
5y = -4x - 8
Divide through by 5
y = -0.8x - 1.6
Express as a function
g(x) = -0.8x - 1.6
Hence, the formula of g(x) is g(x) = -0.8x - 1.6

Answer:
none
Step-by-step explanation:
No work is required to maintain an object at a constant speed with no change in direction. Work is only done when an object is accelerated, or moved some distance in the direction of the net force applied.
you would do no work
