If the population of a certain town decreases by 4.5% each year, we form a geometric sequence with first term equal to 8,500 and r equal to 0.955.

<span>(a)   </span>The equation is then,

<span>                                          An = (8,500)(0.955)^n</span>

Where n is the number of years.

 

<span>(b)   </span>Substituting 7000 to An and solving for n,

7000 = 8500*(0.955)^n

<span>            The value of n from the equation is 4.2 years. </span>

Nimfa-mama [501]

Answer:

Sarah will have $200 after 3 weeks

Step-by-step explanation:

amount saved at the start = $20

amount saved per week = $10

number of weeks = 3

∴ Total savings from allowance  after 3 weeks = 10 × 3 = $30

Amount received in birthday money = $150

∴ Total amount saved after 3 weeks = amount saved at the start + Total savings from allowance  after 3 weeks + Amount received in birthday money

Total amount saved after 3 weeks = 20 + 30 + 150 = $200

Therefore Sarah will have $200 after 3 weeks

Please explain this answer ☹️
GuDViN [60]

Answer:

see explanation

Step-by-step explanation:

Note that cos315° = cos45° and sin315° = - sin45° and

cos45° = sin45° = \frac{1}{\sqrt{2} } = \frac{\sqrt{2} }{2}

Hence

12(cos315° + isin315°)

= 12(cos45° - isin45°)

= 12(\frac{\sqrt{2} }{2} - i \frac{\sqrt{2} }{2})

= 6\sqrt{2} - 6i \sqrt{2}
