Answer:

car value: $4,953.84
population: 446
maybe not

Step-by-step explanation:

All of these exponential function problems use the same equation, but with different plug-in values. These can be easily accommodated by a spreadsheet or graphing calculator.

The general form of the value after t years is ...

(initial value)×(1 +annual growth rate)^(years)

The growth rate is positive for an increase, negative for a decrease.

a) Initial value: 22385; growth rate: -0.14; years: 10

value after 10 years: $22385×(1-0.14)^10 = $4953.84

b) initial value: 290; growth rate: 0.09; years: 5

population after 5 years: 290(1+.09)^5 = 446

c) initial value: $4000; growth rate: -0.10; years: 8

value after 8 years: $4000(1 -0.10)^8 = $1721.86

Selling the car for $1500 is selling it for <em>less than its estimated value</em>. That may not be a good decision.

_____

<em>Additional comment</em>

The property value of the car is not the only consideration when evaluating the sale. Other costs related to the car may come into play, and there may be tax implications.

Answer:

The difference in earnings, over a 30-year career, for men vs women, is $1,200,150

Step-by-step explanation:

Per year.

The average man earns $90,761.

The average woman earns $50,756

So, per year, the difference is:

90,761 - 50,756 = 40,005

Over 30 years:

30*40,005 = 1,200,150

The difference in earnings, over a 30-year career, for men vs women, is $1,200,150

Using the information given, select the statement that can deduce the line segments to be parallel. If there are none, then sele

Nataly [62]

The second choice is correct. Given that angle 2 and angle 6 are congruent, the largest in each of the corresponding triangles are vertical angles meaning that two known angles are known in each triangle (and they are equal) which means that the last "unknown" (angles 3 and 7) are congruent. The lines DC and AB correspond with these defined, congruent triangles meaning they are parallel.
