Answer:

Ver desarrollo en los parrafos que siguen

Step-by-step explanation:

El problema describe todos los pasos para llegar al sistema the equaciones:

y = x^2

y = m x + 4 - 2 m

Luego igualamos las cantidades 'y" y llegamos a la siguiente ecuacion cuadratica en "x":

x^2 = m x + 4 - 2m

luego restamos "m x" y "4" de ambos lados, y sumamos "2 m" de ambos lados para terminar con una ecuacion cuadratica igualada a cero para poder aplicar la equacion cuadratica

x^2 - m x - 4 + 2 m = 0

similar a:

a x^2  + b x + c = 0

donde

a = 1; b = "-m"; y c = "2 m - 4"

Luego usando la ecuacion cuadratica:

nos da de resultado:

[tex]x=\frac{m+/-\sqrt{m^2-4(1)(2m-4)} }{2(1)}[/tex]

Y para que la solucion sea UNICA, es necesario que la cantidad dentro de la raiz sea "cero" de modo que de solamente la solucion

x = m/2

Ahora, requiriendo que el determinante the la ecuacion cuadratica sea cero es:

[tex]m^2-4(2m-4)=0\\m^2-8m+16=0\\(m-4)^2=0\\m-4=0\\m=4[/tex]

ya que reconocemos que el trinomio m^2-8m+16 es un binomio quadrado perfecto; (m-4)^2

Y pidiendo que that binomio quadrado sea cero, es lo mismo que requerir que el binomio (m-4) sea cero, lo que significa que m = 4.

De esta manera, obtuvimos la pendiente "m" de nuestra recta:

y = m x + b

y = 4 x + b

Y como conociamos el valor de "b" usando el hecho de que el punto (2, 4) esta en la recta:

4 = 4 (2) + b

4 = 8 + b

4 - 8 = b

b = -4

Por lo tanto, la ecuacion dela recta es:

y = 4 x - 4

Answer:

P(-11 , 14)

Step-by-step explanation:

Explanation:-

Given points A(-6, 9), B(2, 1); Ratio 5 : 3

The Point P divides the directed line segment from A to B in the given ratio Externally

       5 : 3

A( -6,9)    B(2,1)

we will use formula



                            =   [tex](\frac{5(1)-3(9) }{5-3} ,\frac{5(2) -3(-6)}{5-3})[/tex]

                           =  [tex](\frac{5-27}{2} , \frac{10+18}{2} ) = (-11 , 14)[/tex]

The point P( -11 ,14) divides the directed line segment from A to B in the given ratio Externally

Given:

In ABCD, AB=BC, AD=CD.

To find:

The additional information that can be included in the figure showing kite ABCD with  diagonals AC and BD.

Solution:

We know that, a quadrilateral is a kite if,

1. Two pairs of congruent sides which are adjacent to each other.

2. One diagonal is perpendicular bisector of other.

From the given information, we have two pairs of consecutive congruent sides AB=BC and AD=CD.

ABCD is a kite if it holds the second property, i.e., one diagonal is perpendicular bisector of other.

So, the required additional information is "segment BD is perpendicular bisector of segment AC".

Therefore, the correct option is B.

Answer:

B

Step-by-step explanation:

BD is a perpendicular bisector of AC

Answer:

y = 4/3x - 3

Step-by-step explanation:

y = mx + b

m is the slope and b is the y - intercept

The slope is rise/run, count how much it rises, or goes down, and how much it goes to the right. So there are points highlighted for us already, pick 2 points and count the units between them for rise it's 4, for run it's 3. So the slope is 4/3

b is the y-intercept, it's where the line goes through the y-axis, in this case it's -3

So plug the numbers in and it's y = 4/3x - 3

Answer:

[tex]\frac{cosA-(1+sin2A)^{\frac{1}{2} } }{sinA-(1+sin2A)^{\frac{1}{2} } } =tanA[/tex]

Step-by-step explanation:

Step(I):-

Given

    [tex]\frac{cosA-(1+sin2A)^{\frac{1}{2} } }{sinA-(1+sin2A)^{\frac{1}{2} } }[/tex]    

By using  sin²x+cos²x =1

now

  =  [tex]\frac{cosA-(1+sin2A)^{\frac{1}{2} } }{sinA-(1+sin2A)^{\frac{1}{2} } }[/tex]

=    [tex]\frac{cosA-(sin^{2} +cos^{2}x +2sinAcosA)^{\frac{1}{2} } }{sinA-(sin^{2}x+cos^{2} x +s2sinAcosA){\frac{1}{2} } }[/tex]  

= [tex]\frac{cosA-(sinx +cosx)^{2} )^{\frac{1}{2} } }{sinA-(sinx+cos x)^2){\frac{1}{2} } }[/tex]

After simplification , we get

= [tex]\frac{cosA-(sinA+cosA)}{sinA-(sinA+cosA)}[/tex]

= [tex]\frac{-sinA}{-cosA}[/tex]

= tanA





Answer:

Because even and odd are 2 different ways to determine whether or not you get the right answer for the chosen function.

Step-by-step explanation:

Hope this helps!!!

Answer:

For even functions, we take f(-x) to be the starting function. The y-axis reflection of this function is f(-(-x)), which is equal tof(x). So the relationship f(-x) = f(x) means that the function is the same as its y-axis reflection.

For odd functions, there are two reflections that must occur. First, we start with f(-x). The y-axis reflection of this function is f(-(-x)) = f(x). When we apply an x-axis reflection to this result, we get -f(-(-x)) = -f(x). So the fact that f(-x) = -f(x) means that odd functions are the same as sequential reflections across both the x-axis and the y-axis. (The same sequence of reflections also represents a rotation 180 degrees about the origin).

Probability of an event to occur (P) = [tex]\frac{\text{Favorable event}}{\text{Total outcomes}}[/tex]

1). Probability of getting the red crewmate,

   [tex]P_1=\frac{3}{6}=\frac{1}{2}[/tex]

   Probability of getting a chef hat,

   [tex]P_2[/tex] = [tex]\frac{1}{8}[/tex]

  Probability of getting the red crewmate and the chef hat = [tex]P_1\times P_2[/tex]

   = [tex]\frac{1}{2}\times \frac{1}{8}[/tex]

   = [tex]\frac{1}{16}[/tex]

2). Probability of getting blue crewmate,

     [tex]P_1=\frac{2}{6}[/tex]

          [tex]=\frac{1}{3}[/tex]

   Probability of getting an egg hat,

    [tex]P_2=\frac{2}{8}=\frac{1}{4}[/tex]

   Probability to get the blue crewmate and an egg hat = [tex]P_1\times P_2[/tex]

    Probability of getting a banana hat = [tex]\frac{3}{8}[/tex]

    Probability of getting a green crewmate and banana hat

Step-by-step explanation:

Calculate the unit price of a football and a baseball

2 footballs cost $17.00 , then

1 football costs $17 ÷ 2 = $8.50

A baseball is 50% of a football, thus

cost of base ball = 50% of $8.50 = 0.5 × $8.50 = $4.25

(10)

4 footballs cost $34.00 ( given in table )

6 baseballs cost 6 × $4.25 = $25.50 < $34

Thus 6 baseballs < 4 footballs is True

(11)

The difference in price = $8.50 - $4.25 = $4.25

Thus the difference in price is greater than $3, not less False

(12)

3 footballs cost 3 × $8.50 = $25.50

6 baseballs cost 6 × $4.25 = $25.50

Thus the costs are equal is True

(a)

If 2 chords of a circle intersect then the product of the measures of the parts of one chord is equal to the product of the measures of the parts of the other chord.

(b)

If 2 secants are drawn from an external point to a circle then the product of the measures of one secant's external part and the entire secant is equal to the product of the measures of the other secant's external part and that entire secant.

(c)

If a tangent and a secant are drawn from an external point to a circle , then the square of the measure of the tangent is equal to the product of the measures of the secant's external part and the entire secant.

A radian is defined as the angle subtended at the centre of a circle by an arc equal to the radius of the circle.

Step-by-step explanation:

The given equations are :

2x+ y =5 ....(1)

5x+3y = 12

We need to find the matrix equation that represents the system of equations.

[tex][A]=\left[\begin{array}{cc}2&1&\\5&3\end{array}\right][/tex]

[tex][B]=\left[\begin{array}{cc}5\\12\end{array}\right][/tex]

And

[tex][X]=\left[\begin{array}{cc}x\\y\end{array}\right][/tex]

Hence, the matrix equation is :

[tex]\left[\begin{array}{cc}2&1&\\5&3\end{array}\right] \left[\begin{array}{cc}x\\y\end{array}\right]=\left[\begin{array}{cc}5\\12\end{array}\right][/tex]

Hence, the correct option is (b).

Answer:

Quincy is 5.5 mi/h faster than Marissa

Step-by-step explanation:

Speed

It's required to compare the speed of Quincy and Marissa knowing that Quincy rides his bicycle 1 mile in 4 minutes.

The speed can be calculated as the distance by the time, but it's required to express the speed in miles/hour.

4 minutes is 4/60 = 0.0667 hours, thus Quincy's speed is:

[tex]\displaystyle \frac{1\ mile}{0.0667\ h}=15\ mi/h[/tex]

Quincy rides at 15 miles/hour.

Marissa runs 13,376 feet in 16 minutes. Since 1 mile=5,280 feet:

13,376 / 5,280 = 2.533 miles

16 minutes = 16/60 = 0.2667 hours

Marissa's speed is:

[tex]\displaystyle \frac{2.533\ mile}{0.2667 \ h}=9.5\ mi/h[/tex]

The difference is 15 - 9.5 = 5.5 mi/h

Quincy is 5.5 mi/h faster than Marissa

Answer:

C. x = 3

Step-by-step explanation:

because it is not a function, it's an answer. The other equations are all equal to y, which you can find the x and the y for a coordinate, but for c you have just x, and without y you can't have a function.

Answer:

x = 3

Step-by-step explanation:

Think about an archery practice. One target can get hit by multiple archers, but an archer can only shoot one arrow. Therefore its x = 3, because the same x value can not hit every y. Hope this helps, its for more visual learners.
