C because its true and its 6x+4-2 which gets c
Answer:
a = 5 c =11
Step-by-step explanation:
Answer:
f(8) = 6
Step-by-step explanation:
Just plug in x=8
f(x) = 2(x - 5)
f(8) = 2(8 - 5)
f(8) = 2(3)
f(8) = 6
A vector has length (magnitude) and direction.
Multiplying a vector by a scalar can alter both its length and its direction.
Specifically, you are multiplying by
![- \frac{ \pi }{4}](https://tex.z-dn.net/?f=-%20%5Cfrac%7B%20%5Cpi%20%7D%7B4%7D%20)
.
When you multiply a vector by a negative as in this case the direction changes.
Next when we multiply by a quantity greater than 1 the vector's length increases. When we multiply by a quantity less than 1 the vector's length decreases. Here you are multiplying by a quantity less than 1. For the sake of getting an estimate pi is approximately 3.14 so dividing that by 4 gives you a quantity less than 1.
So multiplying by
![-\frac{ \pi }{4}](https://tex.z-dn.net/?f=%20-%5Cfrac%7B%20%5Cpi%20%7D%7B4%7D%20)
will have the following effects on the vector:
It will face the opposite direction and it will be shorter (have less magnitude). Specifically the magnitude will be
![\frac{ \pi }{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%5Cpi%20%7D%7B4%7D%20)
of what it was before.
