4 2/3 + 3 1/4
(4+3) + (2/3 + 1/4)
7 + 11/12
= 7 11/2

Problem: Using the doubling time growth model, what will the population for a city be in 4 years if the current

yarga [219]

Answer:

In four years the population will be 810,045 rounded to the nearest whole number.

Step-by-step explanation:

I'm not sure what port and d are but here's the solution.

since we know the doubling time we can set up a function where P is the initial value x will actually be the rate, since we know the time, which is what x usually is.

usually an exponential function looks like P*b^x=R where x is the time. We know the time though, 36 years. So we are going to use this to find the rate, which is normally b.

Px^36=2P

We don't need to worry about the actual values of P since we know that P gets doubled. Now we just use algebra to solve.

Px^36 = 2P

x^36 = 2

x = 2^(1/36) or the thirty sixth root of 2, or about 1.019. So we know every year the population increases by about 1.9 percent. I am going to use 2^(1/36) just to keep the answer accurate.

So now using the original equation we have P*(2^(1/36))^x = R where now we can plug in any number for x and get what the population will be that many years after the start. Keep in mind it has to be years though, if you wanted anything longer or less than a year you'd have to convert something.

It asks for 4 years sowe just plug in 4 for x and of course 750,000 for P.

750,000*(2^(1/36))^4 = 810,045 if we round to the nearest whole number.

Also worth noting if you have something like (a^b)^c you can rewrite it as a^(bc) so the exponents multiply together. Just need to make sure c is a power to the whole term a^b.

The slope of line 1 is (blank)

Ray Of Light [21]

Line 1: We are given the points (-3, 1) and (-7, -2).

Line 2: We are given the points (2, -1) and (8, 4).

In order to calculate the slope, we use the formula:

m = (y2-y1)/(x2-x1)

Substitute in the points to find the slope.

Line 1: (-2 - 1)/(-7 - (-3)) = -3/-4 = 3/4.

Line 2: (4 - (-1))/(8-2) = 5/6.
