Answer:

S(n) = 12,000(–0.05)n

Step-by-step explanation:

The function that represents the number of students, S, in the school district after n years is [tex]S=12000(0.95)^n[/tex]

Original population , P  =  12000

Rate of decline, r = 5%

r  =  5/100

r  = 0.05

The number of years = n

The population of students after n years will be given by the formula:

[tex]S =P(1-r)^n[/tex]

Substitute r = 0.05 and P = 12000 into the formula above

[tex]S=12000(1-0.05)^n\\\\S=12000(0.95)^n[/tex]

The function that represents the number of students, S, in the school district after n years is [tex]S=12000(0.95)^n[/tex]

Answer: i believe you're trying to find N, if so N=3

Step-by-step explanation:

you would start by adding +2 to each side of the equation, leaving you with 3n=9

you would then divide each side by 3, which gives you N=3

Answer:

The point of intersection with the x axis are (-2,0) and (8,0)

Answer:

-33 and -21

Step-by-step explanation:

-36, -33, -30, -27, -24, -21, -18

-36

-36 + 3 = -33

-33 + 3 = -30

-30 + 3 = -27

-27 + 3 = -24

-24 + 3 = -21

-21 + 3 = -18

Answer:

x = 119, y =  55

Answer:

x = 119°

y = 55°

Step-by-step explanation:

y + 125 = 180         {linear pair}

       y   = 180 - 125

       y = 55°

Sum of all the angles of quadrilateral = 360

x + 55 + 72 +114 = 360

               x + 241 = 360

                         x = 360 - 241

                        x = 119°

I just want to tell you what a term is because your going to really need it when you go into middle school. So a term is where there is a number or a a number with a variable with it or a variable by itself. For example if there is 4x + 6m + 3 + X you would have 4 terms because you have 4 numbers along with variables and a variable by itself and with some numbers which are Co -Efficient. Co-Efficient is when a number is with a variable the number along with the variable is called a Co-Efficient. Both of them together is called a term so now you know :) The whole equation is called an expression if a a number is by itself like 4 + 3m the 4 would be considered as a constant because its just a normal number standing by itself.

Given:

The function is

[tex]y=\tan x[/tex]

To find:

The domain of the given function.

Solution:

We know that, domain is the set of x-values or input values.

We have,

[tex]y=\tan x[/tex]

[tex]y=\dfrac{\sin x}{\cos x}[/tex]

The functions sin x and cos x are defined for all real values of x. So, the function tan x is defined for all real values of x except those value for which cos x = 0.

So, domain is [tex]-\infty<x<\infty, x\neq \dfrac{\pi}{2}+n\pi[/tex].

Note: All options are incorrect.

Answer:

C

Step-by-step explanation:

all x≠pi/2+pi n

Answer:

Step-by-step explanation:

7-x=-2

-x=-2-7

-x=-9

x=9

Answer:

[-2,4]

Step-by-step explanation:

The domain is just asking for all the possible x values

we can see that the lowest x value is -2 and the highest is 4 which means our answer is

[-2,4]

Answer:

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the

x

-axis. The range is the set of possible output values, which are shown on the

y

-axis. Keep in mind that if the graph continues beyond the portion of the graph we can see, the domain and range may be greater than the visible values.

We can observe that the graph extends horizontally from −5 to the right without bound, so the domain is [−5,∞). The vertical extent of the graph is all range values 5 and below, so the range is (−∞,5]. Note that the domain and range are always written from smaller to larger values, or from left to right for domain, and from the bottom of the graph to the top of the graph for range.
