Answer:
x = 5.2
Step-by-step explanation:
Let's first simplify our first function:
Now, we just need to set this function equal to our other given function.
Now, we can add 12 to both sides:
Now, add 5x to both sides:
Finally, we'll divide both sides by 5:
Answer: x = 5.2
Answer:
Absolute maximum is 2
Absolute minimum at -2
Step-by-step explanation:
The given parametric functions are:
By the chain rule:
At fixed points,
This gives on
This implies that the extreme points are and
By eliminating the parameter, we have
This is a circle with radius 2, centered at the origin.
Hence (0,2) is an absolute maximum ,at and (0,-2) is an absolute minimum at
The cross product of two vectors gives a third vector 
that is orthogonal to the first two.
Normalize this vector by dividing it by its norm:
To get another vector orthogonal to the first two, you can just change the sign and use
