Answer:
B
Step-by-step explanation:
look at the graph, it is really easy with such basic numbers involved :
the red dotted line is
y = 2
since the line is dotted (= the points on the line are not included in the solution), the colored area is below the line is
y < 2
the blue line is clearly just a 45° basic line through the origin (0,0), and that means for every point in that line x is equal to y.
y = x
and the line is solid, so the points are included in the solution. the shaded area is above the line, so, we need to use the ">" relation :
y >= x
the required solution is the combination of both, and therefore, B is correct.
Answer:
-39 cm²/h
Step-by-step explanation:
The area of the rectangle is A = hw where h = height and w = width.
So the rate of change of area with respect to time is
dA/dt = d(hw)/dt
dA/dt = hdw/dt + wdh/dt
Given that at an instant h = 3cm, w = 8 cm and dh/dt = + 11 cm/h and dw/dt = -9 cm/h(negative since it is decreasing)
So, dA/dt = hdw/dt + wdh/dt
dA/dt = 3 cm × (+11 cm/h) + 8 cm × (-9 cm/h)
dA/dt = 33 cm²/h - 72 cm²/h
dA/dt = -39 cm²/h
