37 I think I’m not sure just saying a random number don’t trust me I just needed the points
Area of a square = length²
A = x²
16 = x²; x = 4
dA/dx = 2x cm²/s
dx/dt = 6 cm/s
Using chain rule:
dA/dt = dA/dx * dx/dt
dA/dt = 2x * 6
dA/dt = 12x
At x = 4,
dA/dt = 12(4) = 48 cm²/s
Any
in this set will be real numbers that are both less than
and greater than
. But that's not possible, so this set is empty.
Answer:
8
Step-by-step explanation:
mean of A=28+23+30+25+27/5 = 26.6
average of B=22+19+15+17+20/5 = 18.6
now,
difference= 26.6-18.6
=8,,
