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:

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

Step-by-step explanation:

The range of the data is 14.

What is a boxplot?

A boxplot is defined as a common method for visualizing data distribution based on a five-number summary. (minimum, first quartile (Q1), median, third quartile (Q3), and maximum).

Given that,

The box-and-whisker plot shows the number of books read by history students during the last school year.

The box extends from 4 to 15 on the number line.

There is a vertical line at 8, median = 8.

The whiskers end at 4 and 15,

So, minimum of data = 4 and maximum of data = 15.

∵ Range = maximum of data - minimum of data

Range = 15 - 4

Range = 11

Hence, the range of the data is 14.

Ya tengo el resultado, debe ser "y=4x-4"
Pero le doy 15 puntos al que llegue a ese resultado y explique cómo llegó a él
El método de Descartes para determinar tangentes se basa en la idea de que para muchas gráficas, la recta tangente en un punto dado es una recta "única" que intersecta la gráfica solamente en ese punto. Aplicaremos ese método para determinar la ecuación de una recta tangente a la parábola y=x^2 en el punto (2,4).
Primero, sabemos que la ecuación de la recta tangente debe tener la forma de y=mx+b. Usando el hecho de que el punto (2,4) está en la recta, podemos resolver para b en términos de m y obtener la ecuación y=mx+ (4-2m). Ahora queremos que (2,4) sea la "única" solución del sistema
{ y=x^2
y=mx+4-2m
De este sistema obtenemos x^2-mx+(2m-4)=0. Usando la fórmula cuadrática obtenemos
m+- √(m^2-4(2m-4))
x= --------------------------------
2
Para obtener una solución única para x, las dos raíces deben ser iguales, en otras palabras, el discriminante m^2-4(2m-4) debe ser 0. Completa el trabajo para obtener m y escribe una ecuación de la recta tangente

Answers

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

Quincy rides his bicycle 1 mile in 4 minutes, and his sister Marissa runs 13,376 feet in 16 minutes. In miles per hour approximately how much faster is Quincy than Marissa? (Note: 1 mile = 5,280 feet)

Answers

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

Answers

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

11. The difference in the price of 1 football when compared to the price of 1 baseball is less than $3
12. The price of 3 footballs is equal to the price of 6 baseballs. True or False

Answers

Answer:

True, False, True

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
