Given:

Population in 2002 is 2 million and is growing at 6%per year.

A)

Recursive formula:

P_n=P_{n-1}(1+\frac{6}{100})P_n=P_{n-1}(\frac{100+6}{100})P_n=P_{n-1}(\frac{53}{50})P_0=2.2\text{ }P_n=P_{n-1}(1.06)

B)

P_1=P_0(1.06)P_2=P_1(1.06)P_2=P_0(1.06)_{}(1.06)P_2=2.2(1.06)^2_{}P_n=2.2(1.06)^n_{}

C)

n=2011-2002

n=9

No\text{ of people in 2011=}2.2(1.06)^9No\text{ of people in 2011=}3.7\text{ millon}

Simplify 4/7 + 5/6 whoever possible
Pani-rosa [81]

Hey there!

4/7 + 5/6

≈ 24/42 + 35/42

≈ 24 + 36/ 42 - 0

≈ 59/42

≈ 1 17/42



Therefore, your answer is:

59/42 or 1 17/42

EITHER OF THOSE SHOULD WORK BECAUSE THEY ARE EQUIVALENT.


Good luck on your assignment & enjoy your day!

The correct answer is:  [D]:  " <span>x-int : 1 ,  y-int:  0.5  " .
_____________________________________________________
Note:
_____________________________________________________
The "x-intercept" refers to the point(s) at which the the graph of a function (which is a "line", in this case) cross(es) the "y-axis".  

In other words, what is (are) the point(s) of the graph at which "x = 0<span>" ?
</span>
By examining the graph, we see that when " x = 0" ; y is equal to:  "1<span>" .
</span>
So; the "x-intercept" is at point:  "(0, 1)" ; or, we can simply say that the 
   "x-intercept" is:  "1" .

Can somebody please help me with this ?
mrs_skeptik [129]
Domain is the values of y. 
Plug the x values in the equation to find the corresponding y values:
when x=0, y=3
when x=2, y=-1
when x=-6, y=15
so the answer is D
