Solve the problem.A projectile is fired from a height of 6.6 feet with an initial velocity of 126 ft/sec at an angle of 44° with the horizontal. The parametric equations for the path of the projectile are x = (126 cos 44°)t, and y = 6.6 + (126 sin 44°)t - 16t2,where x and y are in feet and t is in seconds. Determine the rectangular equation describing the path of the projectile.
A. y = 6.6 + 126x tan 44° - 
x2
B. y = 6.6 + 126x tan 44° - 
x2
C. y = 6.6 + x tan 44° - 
x2
D. y = 6.6 + x tan 44° - 
x2
Assume that x, y, and d are positive numbers. Use the properties of logarithms to write the expression 
in terms of the logarithms of x and y.
