A. The variables in the problem include the miles traveled, the cost to rent the car and the cost per mile traveled in the car.
b. The rate of change in the problem is the amount of payment that is expected per mile traveled.
c.The y-intercept is the total cost of the miles traveled without including the deposit.
d. A straight-line function will work for this problem, where y = mx + c.
m = $0.15, c = $25 and x = total miles traveled.
e. y = ($0.15)(1200) + $25
= $180 + $25
= $205

See the answer below
Explanation:
<em>Recall that the law of dilution states that the number of moles before dilution must be equal to the number of moles after dilution.</em>
Mathematically,
molarity x number of moles before dilution = molarity x number of moles after dilution.
For solution A: final molarity = 3 mM, final volume = 2mL, initial molarity of KMnO4 = 10 mM
Applying the equation:
10 x initial volume = 3 x 2
initial volume = 6/10 = 0.6
<u>Hence, Tube A should be made with 0.6 mL of 10 mM KMnO4 stock and 1.4 mL of distilled water to give a solution of 2 mL 3 mM KMnO4.</u>
For solution B:final molarity = 8 mM, final volume = 2 mL, initial molarity = 10 mM
10 x initial volume = 8 x 2
initial volume = 16/10 = 1.6
<u>Hence, Tube B should be made with 1.6 mL of 10 mM KMnO4 stock and 0.4 mL of distilled water to give a solution of 2 mL 8mM KMnO4. </u>
Answer:
Many scientists use dichotomous keys to identify plants, animals, and other organisms. They may also use dichotomous keys to identify species, or to determine whether a particular organism has been identified and described before. However, dichotomous keys are not used only to identify organisms.

1. Lithosphere
2. Hydrosphere
3.atmosphere
4. Biosphere
The lithosphere/geosphere is made of the earth's core, the mantle, crust, ocean floor,mountains, sand, etc.The hydrosphere is made of everything water such as oceans, rivers, lakes, rain, and snow.The atmosphere is made of gasses such as oxygen, and hydrogen.Finally the biosphere is all that has life such as plants, animals, people, insects, etc.
