The population of a city is modeled by the exponential function ƒ (x​) = 689,254 · 2.40.014x​, where x is the number of years af
Alex Ar [27]

Answer:

<h3>2036</h3>

Step-by-step explanation:

Given the population of a city is modeled by the exponential function

ƒ (x​) = 689,254 · 2.4e^0.014x​, where x is the number of years after 2000

In order to determine the year that the city's population will exceed one million, we will substitute f(x) = 1,000,000 and find x first as shown:

1,000,000 = 689,254  2.4e^0.014x​,

1000000/689,254  = 2.4e^0.014x​,

1.4508 = 2.4e^0.014x​,

1.4508 /2.4 = e^0.014x​,

0.6045 = e^0.014x​,

Apply ln to both sides

ln 0.6045 = lne^0.014x​,

-0.5033 = 0.014x

x = -35.95

Since x cannot be negative, lets say x ≈ 36years

<em>This means that the population will exceed one million after about 36 years. The year it will exceed this amount will be 2000+36 = 2036</em>

<em>Note that the exponential equation used was not correctly written but the same calculation can be employed for any exponential functions you might have.</em>

3(X-5)=27. 3x-15=27. 3x=42. X=14. It looks like they tried to add 5 instead of multiplying it, and they added 5 and 27 wrong. :)

X and y simplifying problem. Please explain how to do thiese. I will gove 15 points
Strike441 [17]

\dfrac 56 x + \dfrac25 y - \dfrac14 x + \dfrac3{10} y

First, combine like terms:

\left(\dfrac 56 - \dfrac14\right) x + \left(\dfrac25 + \dfrac3{10}\right)y

Now just simplify the coefficients of x and y. We do this by converting each pair of fractions to ones with a common denominator. Then we can combine them easily.

\dfrac56 - \dfrac14 = \dfrac56\cdot\dfrac22 - \dfrac14\cdot\dfrac33 = \dfrac{5\cdot2}{6\cdot2} - \dfrac{1\cdot3}{4\cdot3} = \dfrac{10}{12} - \dfrac3{12} = \dfrac{10-3}{12} = \dfrac7{12}

\dfrac25 + \dfrac3{10} = \dfrac25\cdot\dfrac22 + \dfrac3{10} = \dfrac{2\cdot2}{5\cdot2} + \dfrac3{10} = \dfrac4{10} + \dfrac3{10} = \dfrac{4+3}{10} = \dfrac7{10}

So the simplified expression would be

\dfrac7{12} x + \dfrac7{10} y
