Step-by-step explanation:
Below is an attachment containing the solution.
Answer:
The base is decreasing at 2 cm/min.
Step-by-step explanation:
The area (A) of a triangle is given by:
(1)
Where:
b: is the base
h: is the altitude = 10 cm
If we take the derivative of equation (1) as a function of time we have:
We can find the base by solving equation (1) for b:
Now, having that dh/dt = 1 cm/min, dA/dt = 2 cm²/min we can find db/dt:
Therefore, the base is decreasing at 2 cm/min.
I hope it helps you!
Answer: just by looking at the graph, it looks like (-1, -2) is the ordered pair. But to be sure, just plug in the ordered pair
Step-by-step explanation:
6x - y = -4
6(-1) - (-2) = -4
-6 + 2 = -4
-4 = -4
