Part A:


An example of a system of inequalities that would only have D and F as solutions is y>x and y>-x . These would both be dotted lines since its not greater than or equal to, and they would be shaded in the upper region since its greater than.


Part B:


You can verify by plugging in the coordinates of D and F into both inequalities. If the coordinates are true for both inequalities, then they are in the overlapping shaded region.


D = (2,4)

F = (-2,3)


4>2 \\ 4>-2 true


3>-2 \\ 3>2 true


Part C:


You can either plug the inequality into a graph. If the coordinate is in the shaded region, in this context it would be able to raise chickens in that farm.


The other option is plugging in the coordinates of each farm into the inequality. If the inequality is true for those coordinates, then that farm can raise chickens.

Given:

Radius of the circle = 4 meters

Measure of arc = 135 degrees

To find:

The area of the sector bounded by the given arc.

Solution:

Formula for area of a sector is:

A=\pi r^2\times \dfrac{\theta}{360^\circ}

Where, r is the radius and \theta is the central angle or measure of intercepted arc.

Putting r=4,\ \theta =135^\circ in the above formula, we get

A=\pi \times (4)^2\times \dfrac{135^\circ}{360^\circ}

A=\pi \times 16\times \dfrac{3}{8}

A=\pi \times 2\times 3

A=6\pi

Therefore, the exact area of the given sector is 6\pi square meters.

Answer:

3) 12 yd^2

4) 27.5 m^2

5) 48 ft^2

6) 96 m^2

Step-by-step explanation:

3) 4(2x3x0.5) = 12 yd^2

4) (9x5)-(0.5)(7x5) = 27.5 m^2

5) (10x6)-(6x2) = 48 ft^2

6) 12x8 = 96 m^2
