D = r x t
replace the d with 84 and replace the t with 6 hours
divide 84 by 6 = 84/6
get the quotient 14
84 = 14 x 6
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.
96,600
= 9.66*10^4
The coefficient should be ≥ 1 and <10~
The final answer is 9.66*10^4~
Answer:
Width=9.5, Length=32.5
Step-by-step explanation:
Let x be the width of the rectangle,
The length is 4 feet more than 3 times the width,
The length= 3x+4
The perimeter is
2(x)+2(3x+4)=84
2x+6x+8=84
8x=76
x=76/8
x=9.5
The Width=9.5
Length= 3(9.5)+4=32.5
