Solve the initial value problem.Differential Equation: 
= (9t2 - 9)i - j + 
kInitial Condition: r(0) = -4i + 7j + 6k
A. r(t) = (3t3 - 9t - 4)i + (7 - t)j + (
- 4)k
B. r(t) = (3t3 + 9t + 4)i + (7 + t)j + (
+ 4)k
C. r(t) = (3t3 - 9t - 4)i + (7 - t)j + (2
+ 4)k
D. r(t) = (9t3 - 9t - 4)i + (7 - t)j + (
+ 4)k
Find all the first order partial derivatives for the following function.f(x, y, z) = x2y + y2z + xz2
A. 
= 2xy; 
= x2 + 2yz; 
= y2 + 2xz
B. 
= 2xy + z2; 
= x2 + yz; 
= y2 + xz
C. 
= 2y + z2; 
= x2 + 2z; 
= y2 + 2x
D. 
= 2xy + z2; 
= x2 + 2yz; 
= y2 + 2xz
