Answer:
A quadratic equation has solutions when the graph crosses the x-axis. There are two ways the graph can have no solution, when the "a" value is greater than 0 and is translated vertically above the x-axis, or if the opposite occurs, when the "a" value is negative and is translated vertically below the x-axis.
discussing factors affecting solubility
Answer:
Step-by-step explanation:
Solubility can be defined as the ability of a solute (could be solid, liquid or gas) to dissolve in a solvent in order to produce a solution. There are several factors affecting solubility which includes (basically four) temperature, polarity, surface area of solute particles and pressure of gases. Generally, an increase in temperature leads to an increase in the solubility of a solute in a solvent. This is because an increase in temperature will increase the average kinetic energy of molecules in the solution which leads to increase interaction between the solute and solvent particles. There is a general saying of "like dissolve like" when discussing polarity. For example, organic solvents are used to dissolve organic solutes (just as petrol is used to wash grease off hands and surfaces). Hence, when the solute and solvent have the same polarity, solubility occurs easily, otherwise solubility may be difficult or may not even occur. A reduced/smaller surface area of the solute leads to an increase in solubility as this makes it easy for the solute particles to interact easily with the solvent. In gases, an increase in pressure increases the interaction between the gaseous molecules of the solute and the solvent, thus leading to an increased solubility. Pressure does not affect solubility in solids and rarely in liquids.
Based on the constraints and objective function that apply to the business student at Nowledge College, the set of linear equations are:
Assume the number of business courses to be x and the number of nonbusiness courses to be y.
The total cost of both need to be less than $3,000 so the inequality is:
60x + 24y ≤ 3,000.
Both courses need to be at least 65 if the student wants to graduate so:
x + y ≥ 65
Business courses should be equal to or more than 23 and nonbusiness courses should be greater than or equal to 20 so:
x ≥ 23
y ≥ 20

Step-by-step explanation:
Answer:
8 thousandths + 6 ones 8 thousandths = 6016 thousandths
Step-by-step explanation:
Answer:
I think it is 16006
Step-by-step explanation:
this because 8 thousands=8000
+
8000+6=8006
soooo,
8000+8006=16006 is the answer

Step-by-step explanation:
so because there is 1 cup of kernels which makes 4 cups of pop corn and there are 8 cups of crenels you would multiply 8 and 4.
4*500=2000
Answer = 2000
Answer:
i think it would be 2000
