Answer:

A shaded region above a solid boundary line.

Step-by-step explanation:

The given inequality is y ≥ |x + 2| -3.

This inequality may be written two ways:

(a) y ≥ x + 2 - 3

y ≥ x - 1

(b) y ≥ -x -2 - 3

y ≥ -x - 5

A graph of the inequality is shown below. The shaded region satisfies the inequality.

D) a shaded region below a dashed boundary line

The < tells us it's dashed if it were (< or =) symbol it would be solid.

then

Graph the inequality by finding the boundary line, then shading the appropriate area.

Oil leaked from a tank at a rate of r(t) liters per hour. the rate decreased as time passed, and values of the rate at two hour

Galina-37 [17]

The given data is
t, h: 0 2 4 6 8 10
r(t), L/h: 8.6 7.9 6.8 6.4 5.7 5.3

The lower and upper estimates for the total amount that leaked may be computed as the Left and Right Riemann sums.

The shape of the graph of r versus will determine which of the two sums yields an upper or lower sum.
The plot of the graph is shown below.

The Left Riemann sum is
Sl = 2*(8.6+7.9+6.8+6.4+5.7) = 70.8 L

The Right Riemann sum is
Sr = 2*(7.9+6.8+6.4+5.7+5.3) = 64.2 L

Answer:
The lower estimate for oil leakage is 64.2 L
The upper estimate for oil leakage is 70.8 L
