Answer:

Given system of inequalities,

-2x + 3y > 3,

4x - 3y < 15,

Graphing -2x + 3y > 3 :

Related equation of line -2x + 3y = 3,

If x = 0,

-2(0) + 3y = 3 ⇒ 3y = 3 ⇒ y = 1,

If y = 0,

-2x + 3(0) = 3 ⇒ -2x = 3 ⇒  x = -1.5,

'>' represents the dotted line,

Join the points (0, 1) and (-1.5, 0) by dotted line.

For (0, 0), -2(0) + 3(0) > 3 ( False )

Shaded region will not contain the origin.

Graphing 4x - 3y < 15 :

Related equation of line 4x - 3y = 15

If x = 0,

4(0) - 3y = 15 ⇒ -3y = 15 ⇒ y = -5,

If y = 0,

4x - 3(0) = 15 ⇒ 4x = 15 ⇒  x = 3.75,

'<' represents the dotted line,

Join the points (0, -5) and (3.75, 0) by dotted line.

For (0, 0), 4(0) - 3(0) < 3 (True )

Shaded region will contain the origin.

It is given that cos 0 = -0.4209 and 0° 0 &lt; 360°. Calculato the values of 0​
beks73 [17]

Answer:

114.89 degrees

245.11 degrees

Step-by-step explanation:

cos is negative in the second and third quadrant ("pointing" on the x-axis to the left).

so, the first answer for the second quadrant is

114.89 degrees.

the answer for the third quadrant is then backwards the same angles from a full 360 degree rotation

360 - 114.89 = 245.11 degrees

A circular plot of land has a diameter of 16 yards. What is the area of theland? Use 3.14 for it.O A. 803.84 yd2O B. 50.24 yd2O
Amiraneli [1.4K]

The area of the circle can be calculated with the following formula

A=\pi\cdot r^2

First let's find the radius

\begin{gathered} r=\frac{16}{2}\text{yds} \\ r=8\text{yds} \end{gathered}\begin{gathered} A=\pi\cdot8^2 \\ A=3.14\cdot64 \\ A=200.96\text{ yd2} \end{gathered}

The answer would be 200.96 square yards
