The parametric equations of the circular cylinder are:
If the orientation of the cylinder is changed to have the height 
along the x-axis, the parametric equations of the cylinder match:
The parametric equations of the circular paraboloid are:
Using the units vectors the parametric equations match:
The parametric equations of the cone are:
Using the units vectors and rotating the base of the cone from 
to 
the parametric equations match:
The equation left is the equation of a plane:
Answer:
Exponential decay
Step-by-step explanation:
Hi there!
We know that this is an exponential function because x is an exponent.
Because the base of the power is 1/2, it is an exponential decay. Whenever the growth/decay factor is less than 1 but greater than 0, it makes the function an exponential decay.
I hope this helps!

We have 55% and 80% antifreeze. We need 90 gallons of 75%.
F - 55% and E - 80%
A) F + E = 90
B) .55 F + .80 E = 67.50 (which is .75 * 90) Multiplying A) by -.55
A) -.55 F -.55 E = -49.50 (which is -.55 * 90) then adding A) & B)
.25 E = 18
E = 72 gallons of 80% and
F = 18 gallons of 55%
********* DOUBLE CHECK ******************
72 * .80 = 57.60 and 18 * .55 = 9.90
57.60 + 9.90 = 67.50 gallons of antifreeze and we have 90 total gallons
(67.50 / 90) * 100 = 75% correct!
