A gym charges an initial fee plus $25 per month. John paid $200 for six months. Assume the relationship is linear.
a.What is the rate of change and what does it mean in context to the situation?
b. What is the initial value and what does it mean and context to the situation?
i will give brainliest!!!!!
Step-by-step explanation:
a. The rate of change is $33.33 per month
200/6 = approximately $33.33 per month
This means that in addition to the initial fee, Josh has to pay $33.33 per month for the gym membership.
b. The initial value is $25. This is a constant value and a one time fee to open and attain a gym membership.

Center (-10, -4), Point on Circle: (4,2)
h=
k=
r^2=
Fill in the parenthesis for the equation of the circle:
(Blank 1)² +(Blank 2)²= (Blank 3)
*Just type what you would write in the parentheses with no spaces
Answer:
(x + 10)² + (y + 4)² = 232Step-by-step explanation:
Given Center = (-10, -4)Point on circle = (4, 2)To find The equation of circleSolutionRemember the standard equation of circle:
(x - h)² + (y - k)² = r², where (h, k) is the center and r is radiusWe have
h = -10, k = -4Use distance formula (Pythagorean theorem) to work out the length of the radius. We know that radius is the distance from the center to any point on the circle.
Here we are finding the distance between points (-10, -4) and (4, 2)
r² = (-10 - 4)² + (-4 - 2)² r² = 14² + 6²r² = 232So the equation is:
(x + 10)² + (y + 4)² = 232Se requiere saber la elevación x los 20.00 m de longitud , al construir una carretera , sabiendo que pendiente es de 5 %
Answer:
La elevación de la carretera es de aproximadamente 0.999 metros.
Step-by-step explanation:
Cuando se dice que la pendiente es de 5 %, se quiere decir que la tangente del ángulo de elevación de la carretera es de 0.05. Trigonométricamente hablando, podemos calcular el ángulo de la pendiente como sigue:
[tex]\theta = \tan^{-1} 0.05[/tex]
[tex]\theta \approx 2.862^{\circ}[/tex]
La elevación de la carretera se determina mediante la función seno:
[tex]\sin \theta = \frac{h}{l}[/tex] (1)
Donde:
[tex]h[/tex] - Elevación de la carretera, medida en metros.
[tex]l[/tex] - Longitud de la carretera, medida en metros.
Si sabemos que [tex]l = 20\,m[/tex] y [tex]\theta \approx 2.862^{\circ}[/tex], entonces la elevación de la carretera es:
[tex]h = l\cdot \sin \theta[/tex]
[tex]h \approx 0.999\,m[/tex]
La elevación de la carretera es de aproximadamente 0.999 metros.
Considerando la regla de tres, la elevación de la carretera es de 1 metro.
Regla de tresLa regla de tres es una forma de resolver problemas de proporcionalidad entre tres valores conocidos y un valor desconocido, estableciendo una relación de proporcionalidad entre todos ellos.
Es decir, lo que se pretende con ella es encontrar el cuarto término de una proporción conociendo los otros tres.
Si la relación entre las magnitudes es directa, es decir, cuando una magnitud aumenta, la otra también (o cuando una magnitud disminuye, la otra también), se debe aplicar la regla de tres directa.
Para resolver una regla de tres directa se debe seguir la siguiente fórmula, siendo a, b y c datos conocidos yx la variable a calcular:
a ⇒ b
c ⇒ x
Por lo tanto: [tex]x=\frac{cxb}{a}[/tex]
ElevaciónUna pendiente de 5% indica que por cada 100 m de longitud hay 5 m de pendiente.
Entonces podes aplicar la siguiente regla de tres: si por cada 100 m de longitud hay 5 m de pendiente o elevación, por 20 metros de longitud ¿cuál será la pendiente?
[tex]elevacion=\frac{20 metrosx5 metros}{100 metros}[/tex]
elevación= 1 metro
La elevación de la carretera es de 1 metro.

Answer:

Step-by-step explanation:
Answer:
First box: F (because we don't know the degrees Fahrenheit yet.
Second box: -62.1 (the degrees Celsius it tells us to find the equivalent of
Step-by-step explanation:
Solving the equation will go like this:
5/9(F - 32) = -62.1
multiply both sides by 9 to get rid of the fraction
5 (F - 32) = -558.9
divide both sides by 5
F - 32 = -111.78
add 32 to both sides
F = -79.78

To find:
The missing values.
Solution:
We have,
[tex]\left(\dfrac{11}{19}n-8\right)+\left(\dfrac{1}{19}n+10\right)[/tex]
It can be written as
[tex]\left(\dfrac{11}{19}n-8\right)+\left(\dfrac{1}{19}n+10\right)=\left(\dfrac{11}{19}n+\dfrac{1}{19}n\right)+\left(-8+10\right)[/tex]
So, the values for the first two boxes are [tex]\dfrac{11}{19}n[/tex] and 10 respectively.
On simplification, we get
[tex]\left(\dfrac{11}{19}n-8\right)+\left(\dfrac{1}{19}n+10\right)=\left(\dfrac{11+1}{19}n\right)+\left(2\right)[/tex]
[tex]\left(\dfrac{11}{19}n-8\right)+\left(\dfrac{1}{19}n+10\right)=\dfrac{12}{19}n+2[/tex]
So, the values for third and fourth boxes are [tex]\dfrac{12}{19}[/tex] and 2 respectively.

3. What is true about the graph of a system of equations that has infinitely many solutions? A. The lines will have the same slope but different y-intercepts. B. The lines will have the same slope and the same y-intercepts. C. The lines will have different slopes and different y-intercepts. D. The lines will have different slopes but the same y-intercepts.
Answer:
B
Step-by-step explanation: for infinitely many solutions the two lines must lie directly on top of one another- so same slope and same y-intercept
The lines in the graph of a system of equations that has infinitely many solutions will have The lines will have the same slope and the same y-intercepts.
What is a slope?A slope is a ratio that describes the steepness and the direction of a line.
What is the y-intercept?The y-intercept is the point at which a line touches the y-axis. This means that x=0.
A system of equations will have infinitely many solutions when they are the same line or when the two lines coincide on every point that makes up the line. Two lines are the same when the slope and the y-intercept of the lines are also the same.Thus we can say that the lines in the graph of a system of equations that has infinitely many solutions will have the same slope and the same y-intercepts. The correct answer is option B.

Answer:
x = 0
Step-by-step explanation:
If the line is parallel to x = 7, it will also be a vertical line.
Vertical lines will only have one possible x-value, and since the line passes through (0, 1), this means the vertical line goes through the x value 0.
The equation of the line will be x = 0
