Answer:
11) Here given Function,

And, 
For f(x) = g(x)






When we solve this equation,
We found,
x = 12.5227 ≈ 12.53
Thus, the required solution is, x = 12.53
12) Here the height of rocket A in x second,

And, The height gain by the rocket B in x seconds,

If at x seconds both A and B gain the same height,
That is, f(x) = g(x)
⇒ 
⇒
⇒ 
⇒ 
⇒ x = 1.125 ≈ 1.13
Thus, the required solution is x = 1.13 seconds (approx)

Solve the second equation for y

Substitute the given value of y into the first equation

Solve the equation for x

Substitute the given value of x into the second equation

Solve the equation for y

The possible solution of the system is the ordered pair (x,y)

Answer:
This is a function and it's because there's only one input for every output.
Step-by-step explanation:
Note: Although 5 and 1 both point to the same number this doesn't take away the validity of the function. :)
A parallelepiped focuses on three-dimensional figures formed by six parallelograms.
<h3>How to explain the parallelepiped?</h3>
A parallelepiped shape has the following features
- They are three-dimensional figures
- They are formed by 6 parallelograms
- Opposite parallelograms are congruent
Think of a cube or a cuboid.
Notice that they contain squares and rectangles
A parallelepiped is to a parallelogram as a square is to a cube and a rectangle to a cuboid
