Answer:
{x | x∈ R, x < -2}
Step-by-step explanation:
Given
See attachment for graph
Required
Determine the inequality
From the attachment, we can see that there is an open circle or -2.
This represents either < or >
<u>Solving further:</u>
The arrow points to the left of -2.
This means that the number line represents numbers less than -2. i.e. < -2
If the numbers are represented with x.
The inequality is: x < -2
So, we have: {x | x∈ R, x < -2}

Answer:
The measure of arc DEF is 204°
B is correct
Step-by-step explanation:
In a circle center at O.
∠DOF and ∠DEF are lie on same base but ∠DOF at center and ∠DEF on circle.
Thus, ∠DOF = 2 ∠DEF
minor ∠DOF = 2 x 78 = 156°
We need to find arc DEF.
DEF is central angle of major∠DOF
major∠DOF + minor ∠DOF = 360° (Complete angle at center)
major∠DOF + 156° = 360°
major∠DOF = 204°
major∠DOF is arc DEF.
Hence, The measure of arc DEF is 204°
Answer:
Gay Lussac's Law - states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. If you heat a gas you give the molecules more energy so they move faster. This means more impacts on the walls of the container and an increase in the pressure.
Step-by-step explanation: An increase in the number of gas molecules in the same volume container increases pressure. A decrease in container volume increases gas pressure. An increase in temperature of a gas in a rigid container increases the pressure
