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
Plug 1 in for x to get 7y=3(1)-7
7y=-4
y=-4/7
Answer:
2 1/4 or 2.25
Step-by-step explanation:
1 1/4 + 1/4 = 1 2/4
1 2/4 + 3/4 = 2 1/4
Recall the fundamental rule of trig:
So, there exists an angle such that
if and only if
Working out the numbers, we get
So, there doesn't exist a number such that
