Answer:
The correct option is 2.
Step-by-step explanation:
It is given that Jane bought a car for $30,303. The value of the car depreciated at a constant rate per year.
The exponential growth and decay function is defined as
Where, P₀ is initial value and r is growth rate.
The initial value of car is $30,303. Let the rate of depreciation be x%.
It means rate of depreciation is 15%. Since the value of car decreased by 15% per year, therefore growth rate is -0.15.
Therefore option 2 is correct.

Given two surfaces for which the vector function corresponding to the intersection of the two need to be found.
First surface is the paraboloid,
Second equation is of the parabolic cylinder,
Now to find the intersection of these surfaces, we change these equations into its parametrical representations.
Let x = t
Then, from the equation of parabolic cylinder, .
Now substituting x and y into the equation of the paraboloid, we get,
Now the vector function, r(t) = <x, y, z>
So r(t) =
