How do you ratify the denominator for 2/ 2(sqrt2)? When I multiply by sqrt2/sqrt 2 I'm still left with a radical in the denominator.

Answers

Answer: [tex]\dfrac{\sqrt{2}}{2}[/tex]

Step-by-step explanation:

Given

The fraction is [tex]\dfrac{2}{2\sqrt{2}}[/tex]

Making denominator a number, multiply and divide by [tex]\sqrt{2}[/tex]

[tex]\Rightarrow \dfrac{2}{2\sqrt{2}}\times \dfrac{\sqrt{2}}{\sqrt{2}}\\\\\Rightarrow \dfrac{2\sqrt{2}}{2\sqrt{2}\times \sqrt{2}}=\dfrac{2\sqrt{2}}{2\sqrt{2\times 2}}\\\\\text{cancel out the common term 2}\\\\\Rightarrow \dfrac{\sqrt{2}}{2}[/tex]

The organizers want the zip line to have two platforms (towers / anchors). The first platform (on the higher ground) should be about 50 m away from the second platform. The slope length from the top of platform one to the top of platform two should be about 70 m. What would be the angle of depression from platform one to two to the nearest degree?

Answers

Answer:

The angle if depression is 44.4 degree.

Step-by-step explanation:

horizontal distance, d = 50 m

slope length, L = 70 m

The angle of depression is given by

[tex]cos\theta=\frac{d}{L}\\\\cos \theta = \frac{50}{70}\\\\cos \theta = 0.714\\\\\theta = 44.4^o[/tex]

Solve for y.
3= y+7 divided by 3

Y=

Answers

Answer:

y=2

Step-by-step explanation:

3 = (y+7)/3

Multiply each side by 3

3*3 = (y+7)/3 *3

3*3 = y+7

9 = y+7

Subtract 7 from each side

9-7 = y+7-7

2 =y

Answer:

2 = y

Step-by-step explanation:

3 = y + 7 ÷ 3

multiply both side of equation by 3

3 × 3 = y + 7 ÷ 3 / 3

9 = y + 7

subtract 7 from both side

9 - 7 = y + 7 - 7

2 = y

how much work is done when you lift an object that weighs 150 N to a height of 5 meters​

Answers

Answer:

Work done = 150 x 5  = 750 J

Step-by-step explanation:

Work done is the measure of energy transferred to an object when a force is added causing the object to move a distance in the direction of the force.

The equation for work done is force time the distance and is measured in Joules. Therefore the formula is W = F x D

work done (W) is measured in joules (J)

force (F) is measured in newtons (N)

distance (d) is in the same direction as the force and is measured in

metres (m)

W = F x D

w = 150 x 5

W = 750 J

Step-by-step explanation:

Hello!

To find f(-7) you simply plug the value, -7, into the function.

This will get you:

f(-7) = 4(-7)^2 - 4(-7)

Remember that the square of a negative number is a positive! Also, remember to use the order of operations (PEMDAS)!

This will get you:

f(-7) = 4(49) - 4(-7)

f(-7) = 196 - (-28)

f(-7) = 224

Step-by-step explanation:

Dado que un político envía un cuestionario a sus votantes para determinar sus intereses acerca de 6 asuntos de importancia nacional: desempleo, medio ambiente, impuestos, tasas de interés, defensa nacional y seguridad social, y los votantes deben seleccionar cuatro asuntos de interés personal y colocarlos en orden 1, 2, 3 y 4 después de cada asunto para indicar el grado de interés, donde 1 indica el mayor interés y 4 el menor interés, para determinar en cuantas formas se puede responder al cuestionario se deben realizar los siguientes cálculos:

6 x 5 x 4 x 3 = X

30 x 4 x 3 = X

120 x 3 = X

360 = X

Por lo tanto, el cuestionario puede ser respondido de 360 formas diferentes.

Esmerelda flips a coin and draws a card. What is the possibility that she gets “heads” and a black card?

Answers

the possibility of flipping heads is 1 in 2 (1/2)
the possibility of pulling a black card is 26 in 52 (26/52) which equals 1 in 2 (1/2)
multiply those together and you get 1 in 4, 1/4, or a 25%

Answer:

1/4

Step-by-step explanation:

The probability of flipping a coin and landing a heads is 1/2. Their are 26 black cards in a standard deck of 52 cards- 26/52 (1/2). Multiply the fractions to get the probability.

1/2 * 1/2 = 1/4

The perimeter of the outer square in thiæ pattern is 8
Ron says, “The perimeter of the inner square is 4"
Do you agree with Ron? Yes
Show workings to support your answer.

Answers

Answer:

The answer is Yes .. Ron is correct

Step-by-step explanation:

This is because each side of the outer square is 2 units summing up to 8 units. So dividing each into two equal parts give 1 unit each.

Each side of the inner square divides the outer square into two making each side 1 unit.

The inner square thus takes 1 unit for it's side summing the perimeter to 4 units.

How do I solve a system of equations algebraically with a substitution method and then write it as a coordinate point?

y = 3x -17 and y = -2x + 8

Answers

To solve it using substitution, you need to plug in one of the equations for y on the other. Since they both equal y, that means the equations also equal each other.

It would be:

3x - 17 = -2x + 8

Then solve. First you can add 2x to both sides.

5x - 17 = 8

Add 17 to both sides

5x = 35

Divide both sides by 5.

x = 5


Since we now have x, we can find y by plugging in 5 for x in any of the equations. I will use y = -2x + 8

y = -2(5) + 8

y = -10 + 8

y = -2


We now have both x and y. As a coordinate point, it would be (5, -2).

What is the area of the polygon given below?

Answers

Answer:

C, which is 340!

Step-by-step explanation:

Split the polygon into two rectangles to make it easier (see the attachment below), and calculate the areas of both rectangles. Then add the areas of the two rectangles, 264+76=340. So the answer is 340 square units, or C. Hope this helped!! :)

The area of polygon = 340 square units.

How to estimate the area of the polygon?

Area of rectangle = Length [tex]\times[/tex] [tex]\tmes[/tex]breadth

Area of rectangle (side A) = 19 [tex]\times[/tex] 4 = 76

Area of rectangle (Side B) = 24 [tex]\times[/tex] 14 = 264

To estimate the area of the polygon, add both of the equations then we get

Area of the polygon

= Area of a rectangle (side A) + Area of a rectangle (Side B)

= 76 + 264

Area of the polygon  = 340 square units.

Therefore, the correct answer is option C. 340 square units.
