QUICK whoever gives correct answer will get brainliest please and thank you.​

Answers

Answer:

B

Step-by-step explanation:

that is the definition of a function : every valid value of x gets exactly one value of y assigned as function result value.

that allows gaps. not every value on the x-axis has to be a valid x value for the function. and neither do we need every possible y value to be a valid function result value.

so, if we consider x to be the set of {2, 4, 6, 9}, then this is indeed a function.

2 gets 3, 4 gets 9, 6 gets 10, and 9 gets 5 assigned as y (function result) value.

all good and perfect - exactly one assigned value for every valid x value.

The angle from a stake in the ground to the top of a tree is 60 degrees. If the height of the tree is 40 feet, what is the distance from the stake to the bottom of the tree (the distance along the gound) in feet? Please explain your answer!

Answers

Answer:

23.09 ft

Step-by-step explanation:

Here we are given that the angle from stake in ground to the top of the tree is 60° and the height of the tree is 40ft . We are interested in finding out the distance from stake to the bottom of the tree . For figure refer to the attachment .

From the figure , BC = 40ft which is the perpendicular of the right angled triangle ABC . Also assume that AB = x ft , which is the base of the triangle .

Now since we have base and perpendicular , we should use the ratio of tangent as ,

[tex]\rm\longrightarrow tan\theta =\dfrac{perpendicular}{base}=\dfrac{p}{b} [/tex]

And here [tex]\theta[/tex] = 60° . On substituting the respective values , we have ;

[tex]\rm\longrightarrow tan 60^o =\dfrac{40\ ft}{x \ }\\ [/tex]

And the value of tan60° = 3 , so that ;

[tex]\rm\longrightarrow \sqrt3 =\dfrac{40\ ft}{x} [/tex]

Cross multiply ,

[tex]\rm\longrightarrow x =\dfrac{40}{\sqrt3}ft. [/tex]

The value of √3 is 1.732 approximately .

[tex]\rm\longrightarrow x =\dfrac{40}{1.732}ft. [/tex]

Simplify,

[tex]\rm\longrightarrow \underline{\underline{\red{{x =23.09\ ft }}}} [/tex]

And we are done !

A game of “Doubles-Doubles” is played with two dice. Whenever a player rolls two dice and both die show the same number, the roll counts as a double. If a player rolls doubles, the player earns 5 points and gets another roll. If the player rolls doubles again, the player earns 5 more points. Whenever the player rolls the dice and does not roll a double, they lose points.

Answer:

[tex]\sf x = 4\sqrt{2}[/tex]

Given:

adjacent: 4 cmhypotenuse: x cmangle: 45°

using cosine rule:

[tex]\sf cos(x) = \dfrac{adjacent}{hypotenuse}[/tex]

[tex]\sf cos(45) = \dfrac{4}{x}[/tex]

[tex]\sf x = \dfrac{4}{cos(45)}[/tex]

[tex]\sf x = 4\sqrt{2}[/tex]

Solution:

Step-1: Find the missing angle.

90 + 45 + y = 180=> 135 + y = 180=> y = 180 - 135=> y = 45°

Step-2: Review the following.

This triangle is an isosceles right triangle because two angles are equivalent.Two sides of the triangle must equal 4 cm.

Step-3: Use Pythagoras theorem.

x² = 4² + 4²=> x² = 16 + 16=> x = √32 ≈ 5.65 cm (Using calculator)

Step-by-step explanation:

Given the expression:

You can simplify it as follows:

1. Apply the Distributive Property multiplying each term inside the parentheses by the number 5 outside:

[tex]=(5)~(4m)-(5)~(6)-10[/tex]

[tex]=20m-30-10[/tex]

2. Add the like terms (remember that like terms have the same variables with the same exponents):

Answers

Answer:

[tex]{x,y}={3,3}[/tex]

Step-by-step explanation:

System of Linear Equations entered :

[tex][1] 2x + 3y = 15\\ [2] x + y = 6[/tex]

Graphic Representation of the Equations :

3y + 2x = 15        y + x = 6  

Solve by Substitution :

// Solve equation [2] for the variable  y

 [2]    y = -x + 6

// Plug this in for variable  y  in equation [1]

  [1]    2x + 3•(-x +6) = 15

  [1]    -x = -3

// Solve equation [1] for the variable  x

  [1]    x = 3

// By now we know this much :

   x = 3

   y = -x+6

// Use the  x  value to solve for  y

   y = -(3)+6 = 3

x= -a-0.5

you add (0.5) to both sides, to cancel out the -0.5 on the left side.

then you have -x=a+0.5

then multiply both sides by (-1) to cancel out the (-x).

so youre left with x= -a - 0.5

A toy maker used 36 batteries for his 9 new toy cars. The toy maker uses the same amount of batteries for each toy car. Which table shows the relationship between the amount of batteries and the amount of toy cars? = 25x

Answers

The table that shows the proportional relationship between the number of batteries and the number of toy cars is as follows:

x = 12, y = 3x = 24, y = 6x = 48, y = 12

Proportional relationship

proportional relationships are relationships between two variables where their ratios are equivalent.

Therefore, If we establish the relationship between the number of batteries and the number of car toys, we can draw the table.

Therefore,

let

y = kx

where

y = number of toys

x = number of batteries

Therefore,

9 = 36k

k = 9 / 36

k = 1 / 4

y = 1 / 4 x

Therefore,

x = 12, y = 12 / 4 = 3x = 24, y = 24 / 4 = 6x = 48, y = 48 / 4 = 12

The question wants to draw a table for the proportional relationship between x(number of batteries) and y(number of toy cars).

The picture above represents a small section from the periodic table. Which of the elements has chemical properties most similar to element X?
A.
Element 1

B.
Element 2

C.
Element 3

D.
Element 4

Answers

The element that has chemical properties most similar to element X is element 1.

What are the relations in the periodic table?

Elements on the periodic table are ordered accordingly to the number of protons in each element.

The first one is hydrogen, with 1 proton, the second is helium, with two protons, and so on.

So, element 3 has one proton less than x, and element 4 has one proton more than x.

Then we have two more relations:

Horizontal lines are called periods, so 3, x, and 4 are on the same period (it is related to the energy level of the valence's electrons).

Vertical lines are called families because elements in vertical lines have similar chemical behavior.

This is the one that we care for this problem, we want to see which element has chemical properties most similar to element X, so we need to see which element is on the same family as element X.

As you can see, the only element on the same vertical line as X is element 1, so the correct option will be A.
