can you devise a relationship between the signs of
partial of f with respect to x
partial of f with respect to y
partial of g with respect to x
partial of f with respect to y

given two multivariable functions f and g and

grad(f) * grad (g)=0??

* means dot product

19. The velocity of an object fired directly upwars is given by V=35-9.8t, where (t) is time in seconds. Which inequality describes the velocity when (t) is between 0.5 and 1.5 seconds? {HINT: remember that when you multiply an inequality by a negative number, you must switch the direction of the inequality.}

MY WORK: solving inequalities

0.5 < 35-9.8t < 1.5
0.5-35 < 35-35-9.8t < 1.5-35
-34.5 < -9.8t < -33.5
-34/-9.8 > -9.8/-9.8 > -33.5/-9.8
3.52 > t > 3.41
[This is what I got, but is not in the answer choices. What am I doing wrong can someone please help me?]

Below are the answer choices:

A.)20.3 > 35-9.8t > 30.1
B.) 4.9 > t > 14.7
C.) 0.5 < t < 1.5
D.) v < 30.1
E.) 20.3 < 35-9.8t < 30.1
F.) 14.7 > 35-9.8 > 4.9
