A city had population 67,255 on january 1, 2000, and its population has been increasing by 2935 people each year since then. A l
irina1246 [14]

We are given: On january 1, 2000 initial population   = 67,255.

Number of people increase each year = 2935 people.

Therefore, 67,255 would be fix value and 2935 is the rate at which population increase.

Let us assume there would be t number of years after year 2000 and population P after t years is taken by function P(t).

So, we can setup an equation as

Total population after t years = Number of t years * rate of increase of population + fix given population.

In terms of function it can be written as

P(t) = t * 2935 + 67255.

Therefore, final function would be

P(t) = 2935t +67255.

So, the correct option is d.P(t) = 67255 + 2935t.

If a car with an average speed of 40 miles per hour drives for 45 minutes how far will it have gone
REY [17]

Answer: 30\ miles

Step-by-step explanation:

The average speed of the car is 40 miles per hour:

V=40\ \frac{mi}{h}

The car drives for 45 minutes:

t=45\ min

Since 1 hours has 60 minutes, we can convert the time from minutes to hours:

(45\ min)(\frac{1\ h}{60\ min})=0.75\ h

Knowing these values, we can use the following formula for calculate the distace "d":

d=V*t

Therefore, substituting values into the formula, we get:

d=(40\ \frac{mi}{h})(0.75\ h)\\\\d=30\ mi
