34 = q + n
6.1 = .25q + .05n
-1.7 = -.05q - .05n
6.1 = .25q + .05n
4.4 = .2q
q = 22
22 of the coins are quarters.
I think that would be 100 million pounds of coal.
Answer:
=
+
+ C where C is the constant of integration.
Step-by-step explanation:
i)it is given that the rate of change of W with respect to x is proportional to
x + 18. Therefore
= k(x + 18) where k is a constant.
ii) Therefore
=
+
+ C where C is the constant of integration.
iii) the complete solution can only be found if we know the constant of proportion and also the constant of integration.
Answer: (-2,2)
