Given that :
log3=0.477 , log4=0.602 and log5=0.699
Now , as you know that
We have to find the value of
So,=
=
Now Putting the values of log3, log4 and log5 in the above expression
=1.0079/0.699
=1.5436..
=1.544 (approx)
So, the value of is 1.544(approx).
Answer:
0.67 cm/s
Step-by-step explanation:
The area of a square is given by :
....(1)
Where
x is the side of a square
Differentiating equation (1) wrt t.
When A = 81cm², the side of the square, x = 9 cm
Put all the values,
So, the length of the side of a square is changing at the rate of 0.67 cm/s.
