Answer:
3cm/s
Step-by-step explanation:
Area of a square is expressed as:
A = L²
Rate of change of area is expressed as:
dA/dt = dA/dL•dL/dt
Given that
dA/dt = 24cm²/s
L = 4cm
Required
dL/dt
Since dA/dl = 2L
dA/dl = 2(4)
dA/dl = 8cm
Subatitute the given values into the formula
24 = 8 dL/dt
dL/dt = 24/8
dL/dt = 3cm/s
Is there a picture with it?
y= (1, 4) times x + (15, 4)
All you have to do is figure out the bases of the figure and use the 12 and 13 in your problems and you should be able to get the right answer.
The answer to this question is 8/10 which also equals 4/5
