Answer: the expected population of the city in 30 years is 5470781

Step-by-step explanation:

The population growth is exponential. The growth rate is exponential. 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 = 3.5 × 10^6

r = 1.5% = 1.5/100 = 0.015

t = 30 years

Therefore,

A = 3.5 × 10^6(1 + 0.015)^30

A = 3.5 × 10^6(1.015)^30

A = 5470781

time = {total paid - 35}/{15}

Put in what we know:
time = {95 - 35}/{15}
time = {60}/{15}
time = 4 hours

Answer:

  • See below

Step-by-step explanation:

<u>Multiply and simplify:</u>

  • (x - 1)(x + 2)(x + 3) =
  • (x² + 2x - x -2)(x + 3) =
  • (x² + x - 2)(x + 3) =
  • x³ + 3x² + x² + 3x - 2x - 6 =
  • x³ + 4x² + x - 6

<u>From the final polynomial we can see that:</u>

  • a = 1, b = 4, c = 1 and d = - 6

So all the coefficients are positive but the constant d is negative
