Find the measure of line segment MK. K 8 I 7 J M 5 2x+1

Find The Measure Of Line Segment MK. K 8 I 7 J M 5 2x+1

Answers

Answer 1

Hello!

This is a problem about relating circle theorems to line lengths.

We can first see that both line segment MK and CM are secants within the circle that come from a common point K.

This means that the Intersecting Secant Theorem applies here.

The Intersecting Secant Theorem states that if two secants are formed from a common point outside the circle, the length of each secant multiplied by the length of its corresponding external secant are equivalent.

We can set up the following equation.

[tex]8(8+x+5)=7(7+2x+1)[/tex]

[tex]8(x+13)=7(2x+8)[/tex]

[tex]8x+104=14x+56[/tex]

[tex]6x=48[/tex]

[tex]x=8[/tex]

Using this value, we can find the length of line segment MK.

[tex]MK=x+5+8[/tex]

[tex]MK=8+5+8[/tex]

[tex]MK=21[/tex]

Hope this helps!

No

Step-by-step explanation:

If we assume there is such a proportion, then we have the proportion:

m(x) = kx, where m is amount the person eats, k is coefficient of proportion, x is age of the person

For 5 year old we have:

m(5) = 5k

For 20 year old:

m(20) = 20k

For 60 year old:

m(60) = 60k

In reality this proportion doesn't make sense as 60 year old normally eats less than 20 year old.

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:

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.

For the area imagine you cut the triangle in half. from P to the middle of NS. Put the 2 triangle halves together to form a rectangle. (PS is now touching NP). This would be a 2x 3.5 rectangle. 2x 3.5 is 7, meaning both this imagined rectangle and the triangle have an area of 7cm^2.

Given {(1, 2), (3, 5), (-2, 2), (3,6)}, choose the pair of coordinates that clarify why this
relation is not a function.

Answers

Given:

The relation is:

[tex]\{(1, 2), (3, 5), (-2, 2), (3,6)\}[/tex]

To find:

The pair of coordinates that clarify why this relation is not a function.

Solution:

A relation is called a function if there exist unique y-value for each x-value. In other words, if a relation has two outputs for a single input, then the relation is not a function.

The given relation is:

[tex]\{(1, 2), (3, 5), (-2, 2), (3,6)\}[/tex]

This relation has two y-values 5 and 6 for a single x-value 3. Since the y-value is not unique all all values of x, therefore the relation is not a function.

Hence, the pairs of coordinates (3,5) and (3,6) clarify that the given relation is not a function.

The following is based on information from The Wolf in the Southwest: The making of an Endangered Species by David E. Brown ( University of Arizona Press). Before 1918the proportion of female wolves in the general population of all southwestern wolves wasabout 50%. However, after 1918, southwestern cattle ranchers began a widespread effort to destroy wolves. In a recent sample of 34 wolves, there were only 10 females. One theoryis that male wolves tend to return sooner than females to their old territories where their predecessors were exterminated. Do these data indicate that the populationproportion of female wolvesis now less than 50% in the region?

Answers

This question is incomplete, the complete question is;

The following is based on information from The Wolf in the Southwest: The making of an Endangered Species by David E. Brown ( University of Arizona Press). Before 1918the proportion of female wolves in the general population of all southwestern wolves was about 50%. However, after 1918, southwestern cattle ranchers began a widespread effort to destroy wolves. In a recent sample of 34 wolves, there were only 10 females. One theory is that male wolves tend to return sooner than females to their old territories where their predecessors were exterminated. Do these data indicate that the population proportion of female wolves is now less than 50% in the region? Use ∝ = 0.01

Answer:

Since p-value (0.0082) < ∝ ( 0.01 ), we reject null hypothesis.

Therefore, at 0.01 significance level, we have sufficient evidence that the population proportion of female wolves is now less than ( 0.5 ) 50% in the region.

 

Step-by-step explanation:

Given the data in the question;

Hypothesis;

H₀ : p ≥ 0.5   { 50% }

H₁ : p < 0.5

This is a lower tailed test { H₁ : p < 0.5 }

sample size n = 34

number of female wolves x = 10

sample proportion p" = x / n = 10 / 34 = 0.2941176

claimed proportion P = 0.5

significance level ∝ = 0.01

we determine the standard deviation of p"

σ[tex]_{p"[/tex] = √[ (p(1 - p)) / n ] = √[ (0.5(1 - 0.5)) / 34 ]

= √[ (0.5 ×0.5) / 34 ]

σ[tex]_{p"[/tex] = 0.08575

Test statistics

[tex]z_{observed[/tex] = (p" - 0.5) / σ[tex]_{p"[/tex]

[tex]z_{observed[/tex] = (0.2941176 - 0.5) / 0.08575

[tex]z_{observed[/tex] = -2.40

so

Test statistic : -2.40  

Since its a lower tailed test;

P-value = P( Z < [tex]z_{observed[/tex] ) = P( Z < -2.40 ) = 0.0082

Rejection criteria: Reject H₀ if p-value < ∝

Decision:

Since p-value (0.0082) < ∝ ( 0.01 ), we reject null hypothesis.

Therefore, at 0.01 significance level, we have sufficient evidence that the population proportion of of female wolves is now less than ( 0.5 ) 50% in the region.
