The population of Ashmore was 925 in 2000 and in 1028 in 2001. the linear model for ashmores population is p= 103t+925, where th

e is the years since 2000.
Find an exponential model, in the form pm a (b)^2, for ashmores population t-ywars after 2000. round b to the nearest thousandth.

How much greater is the population predicted by the exponential model than that predicted by the linear model for the year 2015?

Answer:

exponential population is 2035 greater than the linear model.

Step-by-step explanation:

Exponential modal for the population of Ashmore given in the question after 2000 is in the form of population = a.(b)^{2} Or we can the equation in the form of population = a.(r)^{t}

where "a" is the population of Ashmore in 2000 = 925

r = common ration = 1028/925 = 1.1113

t = years

Now we have to calculate the population for the year 2015

=925.(1.1113)^{15}

= 925 × 4.87 = 4505

population predicted by linear model for year 2015

p = 103t + 925

p = 103×15 + 925

p = 2470

Now the difference in exponential model and linear model will be

= 4505 - 2470 = 2035

Divide known populations:

1028 / 925 = 1.11135

so exponential formula would be 925*1.11135^t

using 15 years:   925 * 1.11135^15 = 4507

linear model: 103(15) +925 = 2470

4507 - 2470 = 2037 more people using exponential

Need some geometry help
GenaCL600 [577]
Check the picture below.

that means

angle AFB is 27 + 2 = 29

angle BFC is 2(27) + 12 = 66

and angle CFD is 2(27) or 54

so hmmmm, you'd know which one isn't there.

The value of x is negative. What must be true about 10 - x? Explain.
pashok25 [27]

What must be true is the expression will actually be adding 10 + (+ x), because of the two marks you have to make when subtracting by a negative.

The subtraction sign is also the negative sign. So in this case, the expression is also saying -x, which means there is two negative signs.

A double negative is a positive, so in this case the x will be turned to a positive integer.

If this is still too confusing, she can plug in a number to replace x. Let’s try it with -2:

Ex. 10 - (-2)= 12.

The two negative signs turn into one positive sign, AKA an addition sign. So, the above expression can be simplified as 10 + 2, or 12.

Jackie ordered a set of wood and metal clothes pins. Of the 276 pins, 172 were wood. What percentage of the clothes pins were me
timurjin [86]

We know that 172 of them were wood, so the rest are metal. To find that number we do:

276 - 172 = 104 metal pins.

To find the percentage that they were metal, take the number of metal pins and divide by the total number of pins:

104/276 is about 0.3768.

Multiply this by 100:

37.68

So, the percent of metal pins is 37.68%.

How to factor ax2 bx c?
Burka [1]

In the same way as you could factor trinomials on the form of

<span><span><span>x2</span>+bx+c</span><span><span>x2</span>+bx+c</span></span>

You can factor polynomials on the form of

<span><span>a<span>x2</span>+bx+c</span><span>a<span>x2</span>+bx+c</span></span>

If a is positive then you just proceed in the same way as you did previously except now

<span><span>a<span>x2</span>+bx+c=<span>(<span>x+m</span>)</span><span>(<span>ax+n</span>)</span></span><span>a<span>x2</span>+bx+c=<span>(<span>x+m</span>)</span><span>(<span>ax+n</span>)</span></span></span>

<span><span>where  c=mn,ac=pq         </span><span>and b=p+q=am+<span>n</span></span></span>
