Suppose a city with population of 400,000 has been growing at a rate of ​5% per year. If this rate​ continues, find the populati
kakasveta [241]

The number of years value isn't given, we could use an hypothetical value, which can be substituted for the correct number of years given in your exercise in other to find the exact answer.

Using a t value of 10 years

Answer:

651558

Step-by-step explanation:

Given that:

Initial population, P0= 400,000

Growth rate, r = 5%

Using the relation :

P(t) = P0 * (1 + r)^t

t = number of years = 10

P(10) = 400000 * (1 + 0.05)^10

P(10) = 400000 * (1.05)^10

P(10) = 400000 * 1.628894626777

P(10) = 651557.8507

= 651558 nearest whole number.

Recall that, the t value used is hypothetical and should be replaces with te exact value given in your question.

Kevin bought a membership to a golf club. He pays $250 per month and $18 every time he plays a round of golf. Write an equation
Arturiano [62]
Hi there!

Let's solve this problem step by step!

The cost of 1 round of golf is $18
and therefore the total cost for all of the tickets is $18 × 
the amount of golf plays, mathematically $18 × g, hence 18g

The membership cost of 1 month is $250
and therefore the total cost for all of the tickets is $250 × 
the amount of months, mathematically $250 × m, hence 250m.

Now we can set up the equation. The only thing we need to do is adding up the individual functions.

Answer:
C = 250m + 18g
