Answer:

 22 \frac{6}{7} × \frac{11}{2}  = 125 .71

Step-by-step explanation:

22 \frac{6}{7} × \frac{11}{2}

   ={[ ( 22 × 7) + 6] ÷ 7 } × \frac{11}{2}

    = \frac{160}{7} × \frac{11}{2}

    = \frac{1760}{14}

     = \frac{880}{7}

   = 125 .71

Answer:

1. $686.94

2. $735.03

3. $10707.55

4. $17631.94

5. $19635.72

Step-by-step explanation:

1st Question:

The interest rate is 7% for each year. This means that each year the person has to pay 7% more than the previous amount. So we need to multiply the initial amount by (0.07+1=1.07) in order to get the interest for the first year. if we want to find the second year's interests then we will have to multiply 2 (1.07)'s and so on.

in this case our function is: 600*(1.07)^t=P(t)

when t=2 P(2)=600*(1.07)^2=$686.94

2nd Question:

Function: 600*(1.07)^t=P(t)

when t=3 P(3)=600*(1.07)^3=$735.03

3rd Question:

initial value=$8500

1+0.08=1.08

Function: 8500*(1.08)^t=P(t)

t=3

P(3)=8500*(1.08)^3=$10707.55

4th Question:

initial value=$12000

1+1.08=1.08

t=5

Function: P(t)=12000*(1.08)^t

P(5)=12000*(1.08)^5=$17631.94

5th Question:

Function: 14000*(1.07)^t=P(t)

P(5)=14000*(1.07)^5

P(5)=$19635.72

A population of geese grow in such a way that each generation is simply 2.2 times the previous generation. There were 3 geese in
lapo4ka [179]
First generation: 3

Second generation: 3\times2.2

Third generation: 3\times2.2\times2.2=3\times2.2^2

Fourth generation: 3\times2.2\times2.2\times2.2=3\times2.2^3

And so on. The general formula for the nth generation is 3\times2.2^{n-1}. So by the 15th generation, you should expect around 3\times2.2^{15-1}\approx186655 geese.

Stolb23 [73]
At 4200, the max tax is about 2,400 so to get to 3200 raise by 800 which is 1/3
so 1/3 of 4000
or do 16.66 times 3200 which gives u about 53333.33
