Answer:
C. supply and demand
Explanation:
<u>In the system of the market economy, the decisions about economic processes are based on the of the people (how much they need and buy something) and the needs of the supply (needs for natural resources, goods, and things which can be bought). </u>
A market economy also means the pricing of the goods is based on the demand for them. If products are not in demand and bought by the customers, it’s the price and supply goes down. Once the demand for the product grows, the profit is made.
The final goal is the price which is <u>equilibrium</u>, meaning goods are supplied exactly by the demand and with the fixed price that makes the process possible. This equilibrium should also provide the profit for the supplier.
Answer:
The diagram shows 4 possible options for the centripetal force acting on the object represented as a black dot. The correct option is the direction marked as C since it points inwards and ties the object to its circular motion.
Below I have included an image that has the measure of all of the angles on it.
We can find the measures of the angles here due to the laws about complimentary angles. A pair of complimentary angles can be formed when 2 lines are perpendicular, and when added together, will always equal 90. The pair are the angles that are not directly adjacent from each other. In this figure, "x" and "(4x-10)" are a pair. According to another law, opposite angles, or adjacent angles, will always be equal to each other. Using the logic above is how we can find the measure of all angles.
Since one angle has a box, we know the lines are perpendicular, and that the laws of complimentary angles apply. We can also use that to see that the angle diagonal from it is equal to 90.
To solve for the other measures, we need to add the 2 equations together and set them equal to 90 (because of that law we talked about before).
x+(4x-10)=90
5x-10=90
+10+10
5x=100
/5 /5
x=20
Now that we know x equals 20, we can substitute that value in and solve.
x=20
=(4x-10)
=(4*20-10)
=(80-10)
=70
We also know this is correct because 20 and 70 equal 90.
