3/2 - x = -12
(multiply everything by 2 to get rid of fraction)
3-2x= -24
3+24 = 2x
3/2 + 12 = x
Step-by-step explanation:
Step one:
given data
we are told that the expression is
v = 4.8m + 8.2
where v is the volume of gas and
m is the number of minutes it has been filling.
Step two:
Required
<em>Asumming the volume is in Liters</em>
the interpretation of the terms in the expression for the volume
4.8 means that for every minute 4.8L of gas enters the gas tank
hence the rate of filling is 4.8L/min
8.2 means that there is 8.2L of gas already in the tank before the filling started.
Answer:
h(t) = 1.5t²/2 + 4t +12
Step-by-step explanation:
The growth rate is given by
dh/dt = 1.5t + 4
To determine the height of the seedlings we integrate the rate with respect to t.
The integral of dh/dt = integral of 1.5t + integral of 4
The integral of dh/dt = h
The integral of dh/dt = 1.5t²/2 + 4t
So at t = 0
h = 12
That makes the equation
h = 1.5t²/2 + 4t +12
Where 12 is the constant
So h(t) = 1.5t²/2 + 4t +12
Will give us the height after t years
