a) The linear function that models the population in t years after 2004 is: P(t) = -200t + 29600.

b) Using the function, the estimate for the population in 2020 is of 26,400.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

The initial population in 2004, of 29600, is the y-intercept. In 12 years, the population decayed 2400, hence the slope is:

m = -2400/12 = -200.

Hence the equation is:

P(t) = -200t + 29600.

2020 is 16 years after 2004, hence the estimate is:

P(16) = -200(16) + 29600 = 26,400.

D=rt for r<br> solve for the specified variable
Harlamova29_29 [7]

Answer:

r=d/t

Step-by-step explanation:

d=rt

we are to make r the subject of the formula, so we remove t from the rhs.

we do this by dividing both sides by t

d divided by t= d/t and rt divided by t = r

therefore d/t =rt/t

= r=d/t

You are driving home on a weekend from school at 55 mi/h for 110 miles. it then starts to snow and you slow to 35 mi/h. you arri
stepladder [879]

Okay lets get started.

I drove 110 miles with speed of 55 mi/hr so the time taken =

time = distance / speed

time = 110 / 55 = 2 hrs For the distance which is covered with 55 mi/hr speed.

Total time for reaching home is 4 hrs 15 minutes. (given in question)

Means rest distance after snow is covered in = 4 hrs 15 minutes - 2 hrs

= 2 hrs 15 minutes = 2 + 15/60 = 2.25 hrs

The speed in snow driving is 35 mi/hr

So distance covered in snow driving is = 2.25 * 35 = 78.75 miles

Hence the total distance = 110 + 78.75 = 188.75 miles : Answer

Hope that will help :)
