Answer:
Second option, h=(
) ft
Step-by-step explanation:
Area = Base x Height
Height = Area ÷ Base
= 
=
(split fraction for easier simplification)
= 
Answer:
B)
Reasoning:
Since X is perpendicular to A and B, that means they are both make a 90 degree angle with X, so they are both parallel. This is the perpendicular transversal theorem.
Answer:
$23.00
Step-by-step explanation:
The tip amount is $3.00, but the total is $23.00
Answer:
The solutions are linearly independent because the Wronskian is not equal to 0 for all x.
The value of the Wronskian is 
Step-by-step explanation:
We can calculate the Wronskian using the fundamental solutions that we are provided and their corresponding the derivatives, since the Wroskian is defined as the following determinant.

Thus replacing the functions of the exercise we get:

Working with the determinant we get

Thus we have found that the Wronskian is not 0, so the solutions are linearly independent.
