FUNCION AFÍN O LINEAL. Una empresa de gas cobra el servicio del siguiente modo: un cargo fijo de $140, mas un importe por el consumo mensual a razon de $25 el m3. A) ¿cuanto debera abonar la familia a la que se le registro un consumo de 140 m3 en el mes de mayo? (Los meses no es de importar :3) B) ¿cual es la formula que define esta funcion para un numero "x" de m3 consumidos? C) representar graficamente la situacion planteada D) ¿que representa en este caso la ordenada al origen? Si alguien me ayuda, de verdad se lo agradezco
Answer:
El costo es:
Primero tenemos un cargo fijo de $140.
Luego tenemos un $25 por cada m^3 consumido.
Entonces, si tenemos x m^3 consumidos en un mes, el cargo de ese mes va a ser:
C(x) = $140 + $25*x.
Esto es una relación linear.
A) En este caso tendríamos x = 140
C(140) = $140 + $25*140 = $3640
B) La formula es, como ya escribimos arriba, C(x) = $140 + $25*x.
C) El grafico estará al final. En el podemos ver que la linea corta el eje vertical en y = $140, que seria lo minimo que se puede pagar al mes, en el caso de que el consumo sea x = 0.
D) La ordenada al origen es $140, representa el cargo fijo que no depende de la variable x.
Kalila Winston worked for a software company for 26 years. She became permanently disabled and could no longer keep her job. She was 52 years old and had planned to work until she was 62. Her final salary was $43,000. Her rate of benefits was 2%. What is Kalila's monthly disability benefit?
Answer:
The monthly disability benefit is $2580
Step-by-step explanation:
Given
[tex]Final\ Salary\ (P) = \$43000[/tex]
[tex]Age = 52[/tex]
[tex]Benefit\ Rate (R) = 2\%[/tex]
Worked = 26 years
Expected = 62 years
Required
Determine the monthly disability benefit
First, we need to determine the years (T) left for her to work;
[tex]T = Expected - Worked[/tex]
[tex]T = 62 - 26[/tex]
[tex]T = 36[/tex]
Next, is to calculate the yearly disability benefit as follows;
[tex]Benefit = PRT[/tex]
Substitute 36 for T, 2% for R and 43,000 for P
[tex]Benefit = 43000 * 2\% * 36[/tex]
Convert percentage to decimal
[tex]Benefit = 43000 * 0.02 * 36[/tex]
[tex]Benefit = 30960[/tex]
There are 12 months in a year;
So; Monthly Benefit is as follows;
[tex]Monthly = \frac{30960}{12}[/tex]
[tex]Monthly = \$2580[/tex]
Hence, the monthly disability benefit is $2580
If an object is projected upward with an initial velocity of 123 ft per sec, its height h after t seconds is h=−16t2+123t. Find the height of the object after 5 seconds.
Answer:
Height after 5 seconds is 215 ft
Step-by-step explanation:
Given that:
The initial velocity of object which is projected upwards is 123 ft/sec.
Height of the object, h after time t in seconds, is given as:
[tex]h=-16t^2+123t[/tex]
Here, t will always be positive, so [tex]123t[/tex] and [tex]16t^2[/tex] will also be positive.
But coefficient of [tex]16t^2[/tex] is negative, that means something is subtracted from the positive term [tex]123t[/tex].
To find:
Height of object after 5 seconds.
Solution:
Given that [tex]t=5[/tex] seconds.
Let us put the value in the given relation of [tex]h[/tex] and [tex]t[/tex]:
[tex]h=-16\times 5^2+123 \times 5\\\Rightarrow h=-400+615\\\Rightarrow \bold{h = 215\ ft}[/tex]
So, height after 5 seconds is 215 ft.
Suppose y varies inversely with x, and y = 3 when x = 1/3. What is the inverse variation equation that relates x and y ?
Answer:
y = [tex]\frac{1}{x}[/tex]
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
To find k use the condition y = 3 when x = [tex]\frac{1}{3}[/tex] , then
3 = [tex]\frac{k}{\frac{1}{3} }[/tex] ( multiply both sides by [tex]\frac{1}{3}[/tex] )
3 × [tex]\frac{1}{3}[/tex] = k
1 = k
y = [tex]\frac{1}{x}[/tex] ← equation of variation

Answer:
Option 3
Step-by-step explanation:
AX and XB are congruent because we know that CD is a perpendicular bisector of AB.
The word "bisector" indicates that AB is cut into two equal parts, which allows us to make that claim.
<AXC≅<BXC because they are both equal to 90 degrees. This is because perpendicular means that the two lines are meeting at a 90-degree angle. Since both of them are 90 degrees, they are congruent.
Lastly, we know that XC ≅ XC since they are the same side.
With that in mind, we are able to prove that triangle AXC and BXC are congruent by SAS or side angle side. (The angle is between the two sides)
The correct choice would be option 3.

Is the range correct for this problem?
Answer:
See below.
Step-by-step explanation:
So, looking at the graph (and you graphed correctly, so nice job :D ) we can see that the range (the span of y-values) covered by the graph is everything less than or equal to 0. Therefore, our range should be all values less than or equal to 0. And this includes 0.
Therefore, in interval notation, our answer is:
[tex](-\infty,0][/tex]
Your answer of:
[tex](0,-\infty)[/tex]
is incorrect for 2 reasons.
First, we need to use brackets for the 0 since we include it in our solution set. (5,0) is a valid point in the equation (it's also the vertex). Thus, we need to use brackets.
Second, traditionally, the smaller unit comes first. 0 is technically greater than negative infinity. Yes, the graph does go from 0 to negative infinity, but conventionally, we would still write negative infinity first.
And everything else is correct (maybe you forgot to add "flipped over x-axis for the first question," however?) so nice work!

a submarine is 50 meter below sea levl. it goes up 15 meters, then goes down 40 meters. what is the submarine' new position relative to sea level ? 1. ( -105 meters) 2. ( -75meters) 3.( -35 meters) 4. ( 25 meters)
Answer:
-75 meters
Step-by-step explanation:
First, subtract 15 from 50, since it is going up:
50 - 15
= 35
Then, add 40, since it is going back down:
35 + 40
= 75
So, the new position is -75 meters relative to sea level
First condition of submarine=50 m below the sea=-50 m
It goes up 15 m, that means we must add up 15 m.
-50 m+15 m=
15 m-50 m=-35 m (35 m below the sea)
And, then goes down 40 m, so we subtract it with 40 m.
-35 m-40 m=-75 m (75 m below the sea)
So, the right answer is 2. (-75 meters)

The three medals earned in the Olympics are the gold, silver, and bronze medals. In the 2014 Winter Olympics, the United States had 28 total medal winners. There were two more gold medals than sivler medals, and the number of bronze medals was four less than the sum of the number of gold and silver medals. How many winners were there of each type of medal? Gold: Silver: Bronze:
Answer:
Let x be the number of silver medals.
As there were two more gold medals than silver ones, gold medals are x+2
We also know that the number of bronze medals was 4 less than the sum of gold and silver, so if there are x + 2 of gold and x of silver, there are x+x+2-4 of bronze.
Now, we can do an equation, as we know there were a total of 28 medals:
x + x + 2 + x + x + 2 - 4 = 28
And we isolate x:
4x = 28
x = 28/4 = 7
There were 7 silver medals, so there were 9 gold ones (7-2) and 12 of bronze (9+7-4).
The number of Gold, Silver and Bronze medals are 9, 7 and 12 respectively.
Let the number of silver medals = s
Let the number of good medals = s + 2
Let the number of bronze medals = 2s - 2
Total medals = 28
Therefore, the value for each medal will be:
s + s+2 + 2s-2 = 28
Collect like terms
4s = 28 - 2 + 2
4s = 28
s = 28/4 = 7
Silver medals = 7
Gold medals = s + 2 = 7 + 2 = 9
Bronze medals = 2s - 2 = 2(7) -2 = 14 - 2 = 12

Mya buys 4 pounds of turkey and 2 pounds of ham.she pays a total of $30,and the turkey cost $1.50 less than the ham.what would be the combined cost of 1 pound of ham and 1 pound of turkey?
Answer:$10.50
Step-by-step explanation:
Let t = cost per pound of turkey
Let h = cost per pound of ham
4t + 2h = 30
t = h - 1.5
substitute h-1.5 in place of t in 1st equation
4(h-1.5) + 2h = 30
4h - 6 + 2h = 30
6h - 6 = 30
6h = 36
h = 6
t = h-1.5 = 4.5
1 pound of turkey costs $4.50
1 pound of ham costs $6.00
----------
cost of 1 pound each $10.50
