The rate of increase is found by differentiating with resepect to time. The product rule comes into play here.
A = LW
dA/dt ≈ (dL/dt)·W + L·(dW/dt)
... = (6 cm/s)·(5 cm) + (7 cm)·(3 cm/s)
... = 30 cm²/s + 21 cm²/s
... = 51 cm²/s . . . . rate of area increase
Answer:
5, -25, 125, -625
Step-by-step explanation:
A geometric sequence is where a number is divided or multiplied by same number continuously
in the third option the number are multiplied by (-5) continuously
It is b Bc if you actually look at the other one it don’t make sense
Length • Width = area. Length is 14. So set it up like an equation. W • 14 = 161. This simplifies to 14W= 161. Divide both sides by 14 to get the variable alone. This gets you 11.5. So the width is 11.5. Hope this helps
