Answer:
square inches per seconds.
Step-by-step explanation:
given that a rectangle is growing such that the length of a rectangle is 5t+4 and its height is √t, where t is time in seconds and the dimensions are in inches
Area of rectangle = length * width
A =
To find rate of change of A with respect to t, we can find derivative of A with respect to t.
WE get
Hence rate of change of area with respect to time is
square inches per seconds.
1/5 of the tank is filled in 1/4 of a minute.
There are 4 periods of 1/4 minute in a minute, because 4(1/4) = 1.
That means that 4(1/5) = the rate, so the rate is 4/5 of a gallon per minute.
