Answer:
70
Step-by-step explanation:
First you want to find the amount of x per 1 y so you divide 21 by 3 to get when x = 7 y = 1. Now you can just multiply 10 by 7 to get 70.
I hope this helps!
It asks for partial derivative, and you have to derive it with respect to 'y' variable.
P is inversely proportional to V
That is P = k/V where k is some constant.
Plug in the given values for P and V:-
25 = k/400 giving k = 10,000
so the relation is P = 10,000 / V
when V = 200 , 200P = 10,000
Its A
First compute the coefficient like this:
Simplifying the fraction over 4! we get:
and the variables are
. So answer
.
The correct answer is C then.
