....... hope it helps you
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
Yes if you convert it into a rational number it will be -155/10
<u>Answer:</u>
- 80 km is 9% of 888.89 km.
<u>Step-by-step explanation:</u>
<u>We know that:</u>
<u>Work:</u>
- 80/9 km = 1%
- => 80/9 x 100 = 100%
- => 8000/9 = 100%
- => 888.89 km = 100% (Rounded to nearest hundredth)
Hence, <u>80 km is 9% of 888.89 km.</u>
Hoped this helped.
