Answer:
9.8 km
Step-by-step explanation:
3(-2x+6) -x+3=0
-6x+18-x+3=0
-7x+21=0
-7x=-21
x=3
y=-2x+6
y=-2(3)+6
=6-6
=0
answer: (3,0)
Answer:
Step-by-step explanation:
Initial Quantity of salt Q(0) = 100 kg
Capacity of tank = 1000 L
Inflow of liquid = 10 l /minute and outflow = same rate thus leaving the content of volume 1000 L at any time
Assume after entering constantly mixes and drains out.
Concentration flow = inflow - outflow
= 0.05(10) - 
i.e.
, Q(0) = 100

Use Q(0) = 5
-45 = A
So the equation would be

a) Initial concentratin = 
b) Use the solution fo rDE substitute t =1
Q(1) = 50-45e^(-0.01) = 5.4477 kg
c) As t becomes large Q = 50
So concentration limit = 50/1000 = 0.05
Let's say the second piece is x ft long
The first piece is 2x ft long
The third piece is x+4 ft long
All of the pieces should add up to 10ft
x+2x+x+4=10
4x= 6
x=1.5ft
The first piece is 2x ft long=3 ft long
(1) I assume "log" on its own refers to the base-10 logarithm.
