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:
The slope between the two points: (3, 20) and (5, 8) is -6.
Step-by-step explanation:
Put the points in the slope formula:
m = (y₂ - y₁)/(x₂ - x₁)
Substitute the values.
m = (8 - 20)/(5 - 3)
Subtract.
m = (-12)/2
Divide.
m = -6
The exchange rate is 60:50 (us:euro)
if you have 70 euros, then x:70
60(x) : 70(50)
60x /60 : 3500/60
x = 58.33
seventy euro dollars = $ 58.33 on that particular day
hope this helps
