That’s quadratic. Here’s how you can tell..
Linear:
Formula: y = mx + b
Example: y = 12x + 3
Appearance: A straight line
Quadratic:
Formula: y = ax^2 + bx + c
Example: y = 12x^2 + 2x + 5
Appearance: A parabola (U)
Not sure if the equation is
or
On the other side of the equation, we'd get
Then
- If it's the second one instead, you can use the same strategy as above:
(Note that this step assume )
Then we get
Answer:
300 ft in one hour.
Step-by-step explanation:
It looks like the boundaries of are the lines and , as well as the hyperbolas and . Naturally, the domain of integration is the set
By substituting and , so , we have
and
so that
Compute the Jacobian for this transformation and its determinant.
Then the area element under this change of variables is
and the integral transforms to
Now compute it.
-0.18 as a fraction is -18/100, and you can simplify it as -4/25, hope this helps
