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.
D. because when you multiply you move your numbers to the left and 1000 has 3 zeros meaning you will move your answer 3 times to the left .

Answer:9.0875
Step-by-step explanation:
[2.4–(0.3–3.21)÷2+0.44÷(−2)]÷ 2/5=
[4.8:2-(-2.91):2-0.44:2]:2/5=
=[(4.8+2.91-0.44):2]*5/2=
=[(7.71-0.44):2]*5/2=
=(7.27:2)*5/2=(7.27*5):(2*2)=
=36.35:4=9.0875
