Since purchasing new gear will reduce cash flow by $5,000, the corporation should keep its old equipment, and the calculation can be defined as follows:
<h3 /><h3>Calculating the Total decrease in net income:</h3>
The following are the costs if the company keeps the old equipment:
$30,000 x 3 years = $90,000 So, the total cost is $90,000.
The following are the costs if the company purchases new equipment:
Calculating the equipment cost that is
$75,000 - $10,000 = $65,000.
$10,000 x 3 years = $30,000. So, the total cost is $95,000.

They are inverse of logarithmic equations. The value of b to the nearest tenth is 0.1
<h3>Exponential equations</h3>
They are inverse of logarithmic equations. Given the exponential function that modelled the penicillin concentration, in micrograms per milliliter as shown:
If the value of P(t) is 10, hence;
Take the ln of both sides
ln0.05 = 6/5 lnb
-2.995 = 1.2 ln b
lnb = -2.495
b = e^-2.495
b = 0.08
Hence the value of b to the nearest tenth is 0.1

Answer: arrange a number of given straight-chain alkanes in order of increasing or decreasing boiling point or melting point.
arrange a series of isomeric alkanes in order of increasing or decreasing boiling point.
explain the difference in boiling points between a given number of alkanes.
Explanation:Table 3.5.1 describes some of the properties of some straight-chain alkanes.
There is not a significant electronegativity difference between carbon and hydrogen, thus, there is not any significant bond polarity. The molecules themselves also have very little polarity. A totally symmetrical molecule like methane is completely non-polar, meaning that the only attractions between one molecule and its neighbors will be Van der Waals dispersion forces. These forces will be very small for a molecule like methane but will increase as the molecules get bigger. Therefore, the boiling points of the alkanes increase with molecular size.
For isomers, the more branched the chain, the lower the boiling point tends to be. Van der Waals dispersion forces are smaller for shorter molecules and only operate over very short distances between one molecule and its neighbors. It is more difficult for short, fat molecules (with lots of branching) to lie as close together as long, thin molecules.
The boiling points shown are for the "straight chain" isomers of which there is more than one. The first four alkanes are gases at room temperature, and solids do not begin to appear until about C17H36 , but this is imprecise because different isomers typically have different melting and boiling points.
