WILL GIVE BRAINLIEST!! The yearly population of a city with a 3% yearly growth rate and an initial population of 30,000 can be modeled by the following function where x is time, in years, from 2015.

f(x) = 30,000(1.03)x

The mathematical domain of this function is all real numbers, and its range is all y-values greater than zero.

Which statements describe how the reasonable domain and range compare to the mathematical ones? Check all that apply.
The reasonable domain has a minimum value.
The reasonable domain does not include zero.
The reasonable range has a minimum value of 30,000.
The reasonable range includes zero.
The reasonable range has an implied, but unknown, maximum value.

Answer:

y= 45

x=9

Step-by-step explanation:

plug 5x into y since y=5x:

5x=4x+9

-4. -4

x=9

5(9)=45

Answer:

x=9 y=45

Step-by-step explanation:

y=4x + 9.......(1)

y= 5x.........(2)

Substitute 5x for y in equation 1.

5x= 4x + 9

5x - 4x = 9 (Collect like terms 5 and 4 have x in common if +4 crossover it changes to -4)

x = 9

substitute 9 for x in equation 2.

y = 5(9)

y = 5 x 9(multiplication)

y = 45

Answer:

0.1%

Step-by-step explanation:

138 into a percent=1.38%

156 into a percent=1.56%

175 into a percent=1.75%

1.38-1.56=0.18

1.56-1.75=0.19

0.19-0.18= 0.1%

The increase in volunteers from year 1 to year 2 is 13.04 % and the increase from year 1 to year 3 is 26.81 %.

The percentage can be defined as a relative value that represents the hundredth part of any quantity.

Given that the number of volunteers in a program during year 1, year 2 and year 3 are 138, 156 and 175 respectively.

The percentage of increase in volunteers from year 1 to year 2 is given below.

Volunteers (%) = [tex]\dfrac {156-138}{138} \times 100[/tex]

Volunteers (%) = 13.04%

The percentage of increase in volunteers from year 1 to year 3 is given below.

Volunteers (%) = [tex]\dfrac {175-138}{138} \times 100[/tex]

Volunteers (%) = 26.81 %

Hence we can conclude the increase in volunteers from year 1 to year 2 is 13.04 % and the increase from year 1 to year 3 is 26.81 %.

  9.  not possible

  13, 14, 19.  AAS — 13: WYX≅AYZ; 14: CFD≅CEB; 19: DEH≅GEF

  15, 16.  not possible

Step-by-step explanation:

9. You're looking for three sides, or two sides flanking a congruent angle. Here, the angle is not between the two sides, so the SAS theorem does not apply. Proving congruence is not possible.

__

13, 14, 19. You have two adjacent angles, followed by a side, so the AAS theorem will prove congruence.  

When you write the congruence statement, you need to make sure the nodes are named in corresponding order. It can be useful to name the nodes in the same order as the elements you claim for congruence. For these, we name the two angle nodes first, then the other end of the side.

13: WYX≅AYZ; 14: CFD≅CEB; 19: DEH≅GEF

__

15, 16. With only one angle and one side, it is not possible to prove congruence.

_____

Additional comment

With these theorems, you are looking for angles or sides that are adjacent (next to each other). In figure 9, there are two sides and an angle, so you might be tempted to claim SAS congruence. The name SAS means the angle must be between the two sides. In that figure, the two sides are adjacent, and the angle is adjacent to only one of the sides (not between them). Hence SAS does not apply.

(You will find later that two sides and a non-adjacent angle will define a unique triangle if, and only if, the angle is opposite the longest of the two given sides. In figures like these, no side lengths are given, and you are not allowed to rely on appearances.)

Step-by-step explanation:

Angle ACO = 140° - x. (Sum of angles in a triangle is 180°)

Now draw the line OD. The triangles ODC and OBC are congruent via the SSS congruence property. (OD and OB are both the radius of semicircle, common side OC, and side CD = CB is given)

Hence Angle BCO = Angle ACO = 140° - x.

Since triangle OBC is an isosceles triangle with OC = OB, this means that Angle CBO is also 140° - x.

By Exterior Angle theorem,

we have Angle AOC = Angles BCO + CBO

=> x = (140° - x) + (140° - x)

=> 3x = 280°

=> x = 280°/3. (B)

Answer:

19.26%

Step-by-step explanation:

Given the original selling price of DVD player as ​$179.30 and the new sale price to be ​$144.77, the the first step in finding the percent​ markdown is to take the difference between the original selling price and the sale price to give $179.30 - $144.77 = $34.53

Percent markdown = original selling price- new sale price/original selling price × 100%

Percent markdown = $34.53/$179.30 × 100%

% markdown = 19.26%

Answer:

16 < n < 40

Step-by-step explanation:

use triangle inequality theorem:

n = length of third side

12 + 28 > n;    n > 40

12 + n > 28;    n > 16

n + 28 > 12  (this inequality can be discounted because it results in a negative)

The above equation equals -27

Answer: 311 bears

Step-by-step explanation:

Population increased by 115% in the 35 years from 1970 to 2005.

Population in 2005 is:

= 270 * 115/100

= 310.5

= 311 bears

Answer:

581

Step-by-step explanation:

270x%115=310.5

We have to round 310.5 to the nearest So 310.5 will be 311  

So if it increased by 115%  we have to add the 115% to 270

270+311= 581  

By the 2005 the population will be 581
