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:

6 x 4 = 24 x $2 = $48

Step-by-step explanation:

The total cost of the rectangular frame is C = $240.

A rectangle is a two-dimensional shape in which the opposite sides are parallel and equal to each other and all four angles are right angles.

Given that, a painting measures 4 by 6 inches, the framing material costs $2 per inch,

We need to find the total cost of framing material

The perimeter is given by:

P = 2x(L + W)

In this case, we know that the frame is 6 inches by 14 inches, then the perimeter will be:

P = 2x(6in + 14in)

P = 2x20in = 40in

Since, the framing material costs $6 per inch, then the total cost of the frame will be:

cost = 40x$6 = $240

Answer:

C= 38 in Approx

A=113 in^2 Aprprox

Step-by-step explanation:

Given data

radius= 6 ft

Circumference, C=2πr

substitute

C=2*3.142*6

C=37.704 in

Area A= πr^2

substitute

A=3.142*6^2

A=3.142*36

A=113.112 in^2

Answer:

C) 5/3

Step-by-step explanation:

The ratio comparing red to blue marbles can be created by putting 5 and 3 together, since there are 5 red marbles and 3 blue marbles

This gets you 5/3

So, the correct answer is C) 5/3

Answer:

5/3

Step-by-step explanation:

This is because there are 5 red marbles and there are 3 blue marbles. If you put them side by side, the ratio is 5:3 or 5/3.

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.

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°

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
