Answer: [tex]12*\sqrt{2}[/tex]

Step-by-step explanation:

We have the equation:

[tex]\frac{14}{\sqrt{2} } + \sqrt{50}[/tex]

we know that:

14*14 = 196

then:

14 = √196

[tex]\frac{\sqrt{196} }{\sqrt{2} } + \sqrt{50} = \sqrt{196/2} + \sqrt{50} = \sqrt{98} + \sqrt{50}[/tex]

Now, we can rewrite:

50 = 2*25

98 = 2*49

This is because we know that 49 and 25 are perfect squares, then:

[tex]\sqrt{98} + \sqrt{50} = \sqrt{2*49} +\sqrt{2*25} = \sqrt{2} *\sqrt{49} + \sqrt{2} *\sqrt{25}[/tex]

Now we can use the common factor √2 and get:

[tex]\sqrt{2} *\sqrt{49} + \sqrt{2} *\sqrt{25} = \sqrt{2}*(\sqrt{49} + \sqrt{25} )[/tex]

and we know that:

7*7 = 49

5*5 = 25

then:

[tex]\sqrt{2}*(\sqrt{49} + \sqrt{25} ) = \sqrt{2}*(7 + 5) = 12*\sqrt{2}[/tex]

the value of b is:

b = 12

What is the interquartile range?

The interquartile range is a measurement of a data set's "middle fifty." A range is a measurement of where a set's beginning and end are located.

To get the interquartile range, we must know the first and third quartiles. To find those, we need to know the median of the data.

The rule for 90 degree clockwise rotation is (h,k) -> (k,-h). This means flip the x-value's sign and then switch x and y's position. For example E (-5,-2), first flip x's sign (5,-2) and then switch x and y's places (-2,5).

PLEASE HELP WILL GIVE BRAINLIEST TO CORRECT ANSWER

Answers

Answer:

Step-by-step explanation:

h(x) = 7 - x - 2x^5

h(-1) = 7 + 1 - 2(-1)^5

h(-1) = 7 + 1 + 2

h(-1) = 10

Now differentiate h(x)

h'(x) = -1 - 2*5*x^4

h'(x) = -1 - 10x^4

h'(x) = -1 - 10(x)^4

h'(x) = -1 - 10 (x)^4

h'(-1) = -1 - 10(10000)

h'(-1) = -1 - 100000

h'(-1) = - 99999

Dos aviones salen del mismo aeropuerto,uno se dirige hacia el norte y el otro,al oriente.Cuando estan a 1580 km de distancia uno del otro,uno de ellos ha recorrido 800 km¿Que distancia ha recorrido el otro avion?

Answers

Answer: El otro avión recorrió a distancia de 1362.5 km.

Step-by-step explanation:

Vamos a definir:

Norte es el eje y-positivo.

Oriente (o este) es el eje x-positivo.

Y también sabemos que si tenemos los puntos (a, b) y (c, d)

La distancia entre esos puntos es:

Distancia = √( (a - c)^2 + (b - d)^2)

Ahora, uno de los aviones va hacia el norte, entonces si el aeropuerto está en la posición (0, 0), después de un rato viajando hacia el norte su nueva posición va a ser (0, A)

Mientras que el que va al oeste va a tener una nueva posición (B, 0)

La distancia entre ellos es:

Distancia = √( (B - 0)^2 + (0 - A)^2) = √( B^2 + A^2)

Sabemos que cuando la distancia entre ellos es 1580 km, uno de ellos ha recorrido 800km, asumamos que A = 800km.

Entonces tenemos la ecuación:

1580 km = √( B^2 + (800km)^2)

(1580km)^2 = B^2 + (800km)^2

(1580km)^2 - (800km)^2 = B^2

√((1580km)^2 - (800km)^2 ) = B = 1362.5 km

El otro avión recorrió a distancia de 1362.5 km.

find the value of each angle.​

Answers

Answer + Explanation:

First, find what the sum of the interior angles must be. You can use the formula 180(n - 2) where n is the number of sides to find this.

n = 5, so 180( 5 - 2) = 180 * 3 = 540 degrees.

Then, you can add up all the interior angles of the pentagon and it will add to 540. This means that:

2x + x + 2x + 90 + 90 = 540

5x + 180 = 540

5x = 360

x = 72

Then you can go through and find the measure of each angle:

S = 90 degrees (given)

T = 2x = 2 * 72 = 144 degrees

U = x = 72 degrees

V = 2x = 72 * 2 = 144 degrees

W = 90 degrees (given)

Answers

Answer:

0.46875 ; 1.133 ; $17 ;19.27

Step-by-step explanation:

Number of slots = 32

0, 00, {1,.. 30}

Odd outcomes = {1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29}

1.) probability of winning :

P(winning) = number of odd outcomes / tot possible outcomes

P(winning) = 15 / 32 = 0.46875

2.)

Odds against winning :

Number of losing outcomes / number of winning outcomes

Not odd numbers / odd numbers = 17 /15 = 1.133

C.)

Payoff odd = 1:1

If bet value = $17 ;

Profit made on winning = $17 * 1 = $17

d.)

If Payoff odd = odd against winning = 17 / 15

Profit on $17

17/ 15 * 17

(1.1333333) * 17

So the first step would be is to multiply the denominators so you would get this:

6/30 + 5/30

Then you would have 11/30 no simplification needed.

Se image below for more info:

Answer:

11/30

Step-by-step explanation:

To add fractions, you need to find the common denominators

the common denominator for 5 and 6 is 30, because 5*6 = 30

1/5 times (6/6) to get a common denominator of 30. Remember, you have to multiply the numerator by 6 too!

1           6          6

_    x    _    =    _

5         6          30

Now, we just have to multiply 1/6 by (5/5) to get a common denominator of thirty.

1           5          5

_    x    _    =    _

6         5          30

5             6         11

_     +      _    =    _

30          30        30

You final answer should be 11/30

The perimeter of a rectangular coffee table is given by the trinomial 2t2+4t+2. The table's length is 2t-3. What is the table's width?

Answers

Answer:

t^2+4

Step-by-step explanation:

The perimeter of the table can be given by the equation 2l+2w, and we know the length is 2t-3, meaning 2(2t-3)+2w=2t^2+4t+2, as we know 2t^2+4t+2 is the perimeter. Simplifying we get:

4t-6+2w=2t^2+4t+2

4t+2w=2t^2+4t+8

2w=2t^2+8

w=t^2+4

This means that the table's width is t^2+4

A city council organized a marathon race to promote good health. There were 3 times as many female participants as male participants in the marathon. If the total number of participants was 812, how many participants were male

Answers

Answer:

609 males

Step-by-step explanation:

A city council organized a marathon race to promote good health.

Let the number of

Females = x

Males = y

There were 3 times as many female participants as male participants in the marathon.

3x = y

If the total number of participants was 812,

x + y = 812..... Equation 1

We substitute 3x for y in Equation 1

x + 3x = 812

4x = 812

x= 812/4

x = 203 females

3x = y

Solving for y

3(203) = 609 males

The number of males participants = 609

using the parent function y = mx + b,
y = -3x
slope is m- so rise over run -3/1 = -3
where the line crosses the y axis is b- 0 (origin)
ExplanationFind the slope by using rise over run with two coordinate points.

[tex](0,0) \longrightarrow \sf{part \: \: of \: \: the \: \: graph} \\ (1, - 3)\longrightarrow \sf{given \: \:coordinate \: \: point}[/tex]

[tex]m = \frac{dy}{dx} = \frac{y_2-y_1}{x_2-x_1}[/tex]

Substitute these coordinate values in.

[tex]m = \frac{0 - ( - 3)}{0 - 1} \\ m = \frac{3}{ - 1} \\ m = - 3[/tex]

Hence, the slope is -3.

Find the y-intercept.

From the graph, the line passes through the origin point. Therefore, the y-intercept is (0,0).

Slope-Intercept form

[tex]y = mx + b \\ \begin{cases} \sf{m = slope} \\ \sf{b = y - intercept} \end{cases}[/tex]

Substitute both m and b in the slope-intercept form.
