A car with an initial cost of $33,000 is decreasing in value at a rate of 7% each year. Write the exponential decay function to
Brut [27]

Answer:

n= 11.65 years

Step-by-step explanation:

Giving the following information:

Present Value (PV)= $33,000

Future Value (FV)= $15,000

Decrease rate (d)= 7%

<u>To calculate the number of years it will take to reach $15,000; we need to use the following formula:</u>

<u></u>

n= ln(FV/PV) / ln(1+d)  

n= ln(15,000/33,000) / ln(1.07)

n= 11.65 years

The local operations manager for the Internal Revenue Service must decide whether to hire one, two, or three temporary tax exami
Helga [31]

Answer:

If she uses the Laplace criterion, the number of new examiners she will decide to hire is:

c. three

Step-by-step explanation:

a) Data:

Number of           Compliance

examiners     Low   Normal   High

One               50        50         50

Two              100        60         20

Three           150        70         -10

b) Outcome Calculations:

Number of                     Compliance

examiners            Low                      Normal                High

One              16.65 (50 *.333)     16.65 (50 *.333)     16.65 (50 *.333) =  50

Two              33.3 (100 *.333)      19.98 (60 *.333)      6.66 (20 *.333)  = 60

Three           49.95 (150 *.333)    23.31 (70 *.333)     -3.33 (-10 *.333) =  70

c) Decision:

Three has the highest payoff condition and is selected.

d) The Laplace criterion assumes that each compliance state is equally likely to happen.  Therefore, it assigns the same weight to each state of compliance.  Since there are three states of compliance, we shall assign each state a weight of 0.333.  The number of examiners that have the highest payoff condition is three, and therefore, the number "three" is selected.

A book sold 33,200 copies in its first month. Suppose this represents 7.4% of the number of copies sold to date. How many copies
Marta_Voda [28]

Answer: 448648

Step-by-step explanation:

33,200 copies represent 7.4% of the total amount

-----------------------------------------------------

#1  33,200 ÷ 7.4%

- this is because how we get 33,200 by calculation is use the total amount and times 7.4% to get 33,200. So we are just working backwards. Since it was times before, then we divide after.

 33,200÷7.4%

=33,200÷0.074

≈448648 (you can't round up when the real amount is less the exact amount)

Help plz its math and i will give brainlest if u answer
lesantik [10]

Answer:

not a right triangle

Step-by-step explanation:

We can use the Pythagorean theorem to see if it is a right triangle

a^2 + b^2 = c^2

15^2 + 12^2 = 21^2

225 + 144 = 441

369 = 441

This is not true so it is not a right triangle
