Answer:
Explanation:
Wind, solar and hydroelectric systems generate electricity with no associated air pollution emissions. Geothermal and biomass systems emit some air pollutants, through total air emissions are generally much lower than those of coal and natural gas fired power plants.
Inequalities are used to represent unequal expressions.
The solution set to
is: 
The inequality is given as:

From the inequality above, we have the following observation.
- The value of variable x starts from 7/16 (inclusive)
- The value of variable x has no end (i.e. infinity)
Because, 7/16 is inclusive of the values of x, we make use of the open square bracket i.e. [
We treat
, as an exclusive value. So, we make use of the close parenthesis i.e. )
Hence, the solution set is:

The panel that best describes what happens in this market if there is an increase in the productivity of almond harvesters is Panel (a).
<h3>What is demands?</h3>
Demand is known to be the rate or the quantity of consumers who are known to be readily available or willing and able to buy a given products at any prices in course of a given period of time.
Note that the Demand for any commodity is one that tells that the consumers' need to get the good, their willingness also to pay for it.
Therefore, The panel that best describes what happens in this market if there is an increase in the productivity of almond harvesters is Panel (a) because it is the one among the options that tells us about the increase in productivity.

The angle of elevation of the ground is the angle between the ground and the line of sight
The angle of elevation of the ground is 30.46 degrees
<h3>How to calculate the angle of elevation</h3>
The angle of elevation is calculated using the following tangent ratio

Evaluate the quotient

Take the arc tan of both sides

Using a calculator, we have:
= 30.46
Hence, the angle of elevation of the ground to the nearest tenth of a degree is 30.46 degrees
