The population of an Asian country is growing at the rate of 0.7% annually. If there were 3,942.000 residents in the city in 199

Anettt [7]

Answer:

b) 4,000,000

Step-by-step explanation:

Let the population is measured since 1995,

Given,

The initial population, P = 3,942,000,

Annual rate of growing, r = 0.7% = 0.007,

If y represents the population after t years

So, the population after t years would be,

$y=Pe^{rt}$

$y=3942000(2.7)^{0.007x}$

Therefore, the population after 5 years,

$y=3942000(2.7)^{0.007\times 5}=3942000(2.7)^{0.035}=4081448.78924\approx 4000000$

Hence, the population in 2000 would be approximately 40,00,000.

Option 'b' is correct.

What is log(4k-5)=log(2k-1)?

Paha777 [63]

Log(4k - 5) = log(2k - 1)
log(4k) - log(5) = log(2k) - log(1)
0.6020599913k - 0.6989700043 = 0.3010299957k - 0
0.6020599913k - 0.6989700043 = 0.3010299957k
-0.6020599913k -0.6020599913k
 -0.6989700043 = -0.3010299957k
 -0.3010299957 -0.3010299957
 2.321928094 = k

Ron needed to buy a new jacket for his upcoming ski trip. The ticket price of the jacket was $199.00. After the sales tax was ad

Levart [38]

Answer: 5%

Step-by-step explanation:

Given that:

Ticket price of jacket = $199

Final price after addition of sales tax = $208.95

Percentage sales tax on the jacket =?

Final price after addition of sales tax = price of jacket + amount of sales tax paid

208.95 = 199 + amount of sales tax paid

amount of sales tax paid = 208.95 - 199

amount of sales tax paid = $9.95

Let Percentage of sales tax = x

(x / 100) * 199 = 9.95

199x / 100 = 9.95

199x = 995

x = 5

Hence percent sales tax paid = 5%
