Cоnsider the fоllоwing set of pаrаmetric equаtions: x ( t ) = 4 t y ( t ) = 8 t + 5 {"version":"1.1","math":"begin{align*} x(t) &= 4sqrt{t} \ y(t) &= 8t+5 end{align*}"} Part A -- 5 points Find the derivative dydx{"version":"1.1","math":"dydx"} in terms of t{"version":"1.1","math":"t"} using parametric differentiation methods. Write your answer in the first answer box. Part B -- 5 points Eliminate the parameter t{"version":"1.1","math":"t"} to obtain an equation for y{"version":"1.1","math":"y"} in terms of x{"version":"1.1","math":"x"}. Write your answer in the second answer box. Note: This part does not utilize the result from Part A. Part C -- 5 points Using the original parametric equations as a reference, convert your answer from Part B from a function of t{"version":"1.1","math":"t"} to a function of x{"version":"1.1","math":"x"}. Take a standard derivative of this and write your answer in the third answer box.
