The population of a town is 14,000 and is decreasing at a rate of 1.5% each year. Write an exponential decay equation to find th
sergejj [24]

Answer: the population after 10 years is 12036

Step-by-step explanation:

We would apply the formula for exponential growth which is expressed as

A = P(1 - r)^ t

Where

A represents the population after t years.

t represents the number of years.

P represents the initial population.

r represents rate of growth.

From the information given,

P = 14000

r = 1.5% = 1.5/100 = 0.015

t = 10 years

Therefore, the exponential decay equation to find the population of the town after 10 years is

A = 14000(1 - 0.015)^10

A = 14000(0.985)^10

A = 12036

Answer:

469.42 ft²

Step-by-step explanation:

  • Law of sines;

         w/sin27 = 38/sin40

                   w = sin27*38/sin40

                    w = 26.84 ft

  • Angle x;

            ∡X = 180 - 27- 40 = 113º

  • Area;

              A = 0.5*(26.84)*(38)*sin(113)

            A = 469.42 ft²

QF Q7.) Use properties of logarithms to expand the logarithmic expression as much as possible. Evaluate logarithmic expressions
Softa [21]
Attached is the solution.
The following log properties are used:
log(x^n) = nlog(x)
log(\frac{a}{b}) = log(a) - log(b) \\  \\ log(ab) = log(a) + log(b) \\  \\ log_9 (81) = 2 \rightarrow 9^2 = 81

Solve for c: c= 5 5/6 x 2<br> A. 10 5/6<br> B. 11 2/3<br> C. 10 2/3<br> D. 11 5/6
exis [7]

Answer:

B. 11 2/3

Step-by-step explanation:

c = 5 5/6*2

Change the mixed number to an improper fraction

5 5/6 = (6*5+5)/6 = (30+5)/6 = 35/6

c = 35/6 *2

c = 35/6 *2/1

  = 70/6

Now we change it back to a mixed number

6 goes into 70 11 times

11*6 = 66 with 4 left over

11 4/6

We can simplify 4/6 by dividing the top and bottom by 2

11 2/3
