Según el ministerio de salud en número de infectados por un virus tiene un crecimiento exponencial, según el siguiente modelo matemático N=2e^0,5t donde t es el número de días transcurridos desde que se detectaron los 2 primeros casos. Fiorella una estudiante del curso de comma al ver el modelo matemático menciona que luego de 8 días el número de infectados sería 129, Jorge su compañero menciona que Fiorella está equivocada ya que el número de infectados es 109. A. ¿Quién tiene la razón? B. ¿Cuál es el número de infectados en un mes? C. ¿En que tiempo se estiman 10 000 infectados?

Answers

Answer 1

Answer:

A) Jorge tiene razón en su afirmación.

B) El número de infectados será de 6538035 personas en un mes.

C) Se requiere aproximadamente 5 días para alcanzar 10000 infectados.

Step-by-step explanation:

A) Sea el número de infectados por un virus representado por el modelo matemático [tex]N(t) = 2\cdot e^{0.5\cdot t}[/tex], si [tex]t = 8[/tex], entonces tenemos que la cantidad infectados por el virus sería:

[tex]N(8) = 2\cdot e^{0.5\cdot (8)}[/tex]

[tex]N(8) \approx 109.196[/tex]

En consecuencia, Jorge tiene razón en su afirmación.

B) Si tenemos que [tex]t = 30[/tex], entonces el número de infectados en un mes es:

[tex]N(30) = 2\cdot e^{0.5\cdot (30)}[/tex]

[tex]N(30) \approx 6538034.745[/tex]

El número de infectados será de 6538035 personas en un mes.

C) Si tenemos que [tex]N(t) = 10000[/tex], entonces el tiempo estimado para tal cantidad es:

[tex]t = \frac{1}{2} \ln \frac{N(t)}{2}[/tex]

[tex]t \approx 4.259\,dias[/tex]

Se requiere aproximadamente 5 días para alcanzar 10000 infectados.

Which equation matches the function shown in the graph?
A. Y= sin(x-pi)+3
B. Y= 3cos(x+pi)
C. Y= 3sin(x-pi)
D. Y= 3cos(x-pi)

Answers

Answer:

its c ! just took the test :)

Option C is correct. The equation that matches the function shown in the graph is expressed as y = 3sin(x-π)

The general formula for a sine function is expressed as;

y = Asin(x+Ф)

A is the amplitude i.e the maximum point on the curve. From the diagram, we can see that the maximum point is at 3 (factor 3 elongates the curve).

A = 3

Also, since the graph translates to the right by π, hence Ф = -π

Substituting the resulting values into the formula, we will have;

y =3sin(x+ (-π))

y = 3sin(x-π)

Hence the equation that matches the function shown in the graph is expressed as y = 3sin(x-π)

Ricky made approximately 4 goal points for every 7 of his shots on goal. What is the probability that Ricky would make 2 goal points on two shots in a row during the season?

Answers

Given:

Ricky made approximately 4 goal points for every 7 of his shots on goal.

To find:

The probability that Ricky would make 2 goal points on two shots in a row during the season.

Solution:

Using the given information, the probability of a goal point on one shot is:

[tex]P(one\ goal)=\dfrac{4}{7}[/tex]

We need to find the probability that Ricky would make 2 goal points on two shots in a row during the season.

Since the both shots are independent events therefore,

[tex]P(Two\ goals)=P(one\ goal)\times P(one\ goal)[/tex]

[tex]P(Two\ goals)=\dfrac{4}{7}\times \dfrac{4}{7}[/tex]

[tex]P(Two\ goals)=\dfrac{16}{49}[/tex]

Therefore, the required probability is [tex]\dfrac{16}{49}[/tex].

EF = 12

arc AG = 62°

Step-by-step explanation:

EF² + 13² - 5² = 169 - 25 = 144

EF = √144 = 12

∠AEG = 90° - 28° = 62°

arc AG = 62°

A wading pool is being filled with water from a garden hose at a rate of
6 gallons per minute. If the pool already contains 80 gallons of water and can hold
152 gallons, after how long will the pool overflow?
Assume m minutes later, the pool would overflow. Write an equation to model this scenario. There is no need to solve it.

Answers

152-80 = 72+1 (overflow). Divided by 6

A wading pool is being filled with water from a garden hose at a rate of

6 gallons per minute. If the pool already contains 80 gallons of water and can hold 152 gallons, and it will take 12 minutes for the pool to overflow.

In this scenario, we have a wading pool being filled with water from a garden hose at a constant rate of 6 gallons per minute. The pool already contains 80 gallons of water, and its maximum capacity is 152 gallons. We want to find out how long it will take for the pool to overflow.

Let's use "t" as the variable representing time in minutes. After "t" minutes, the amount of water in the pool will be the initial 80 gallons plus the additional water being filled by the hose at a rate of 6 gallons per minute. We can express this mathematically as:

Amount of water in the pool after "t" minutes = 80 gallons + 6 gallons/minute * "t" minutes

Now, we want to find out when the pool will overflow. The pool's capacity is 152 gallons, so we set up an equation to represent this:

Amount of water in the pool after "t" minutes = 152 gallons

Substituting the earlier expression for the amount of water in the pool after "t" minutes:

80 gallons + 6 gallons/minute * "t" minutes = 152 gallons

Now, we have an equation to model the scenario: "80 + 6t = 152".

To find the time "t" it takes for the pool to overflow, we need to solve this equation for "t."

To solve for "t," we need to find the value of "t" that satisfies the equation we derived earlier:

80 + 6t = 152

To isolate "t," we'll perform the following steps:

Subtract 80 from both sides to move the constant term to one side of the equation.

80 + 6t - 80 = 152 - 80

This simplifies to:

6t = 72

Divide both sides by 6 to solve for "t."

t = 72 / 6

t = 12

So, it will take 12 minutes for the pool to overflow.

In summary, we have a wading pool being filled with water at a rate of 6 gallons per minute, and we want to know when it will overflow, given its current water level of 80 gallons and a maximum capacity of 152 gallons. The equation "80 + 6t = 152" models this situation, with "t" representing the time in minutes. Solving this equation will give us the time it takes for the pool to overflow.

Answer:

C

Step-by-step explanation:

We know that ∠ 1 + ∠ 2 + ∠3 = 180 → (1)

and ∠ 3 + ∠ 4 = 180 → (2)

From (2) ∠ 3 = 180 - ∠ 4

Substitute ∠ 3 = 180 - ∠ 4 into (1)

∠ 1 + ∠ 2 + 180 - ∠ 4 = 180 ( add ∠ 4 to both sides )

∠ 1 + ∠ 2 + 180 = 180 + ∠ 4 ( subtract 180 from both sides )

∠ 1 + ∠ 2 = ∠ 4 → C
