Answer:

[tex]y=x^2[/tex]

Step-by-step explanation:

The given relation is

D={(x,y):(3,9),(5,25),(-2,4)}

We can see that;

[tex]3\to 3^2=9[/tex]

[tex]5\to 5^2=25[/tex]

[tex]-2\to (-2)^2=4[/tex]

Hence in general,

[tex]x\to x^2[/tex]

Therefore the equation for the relation is;

[tex]y=x^2[/tex]

Answer:

D

Step-by-step explanation:

given a quadratic equation in standard form

ax² + bx + c = 0, then the discriminant is

Δ = b² - 4ac

x² + 3x - 4 = 0 ← is in standard form

with a = 1, b = 3, c = - 4

b² - 4ac = 3² - (4 × 1 × - 4) = 9 - (- 16) = 9 + 16 = 25 → D

Answer:

x=-25

Step-by-step explanation:

Inverse variation

xy =k

We know x and y

20*5 =k

100 =k

So the formula is

x y = 100

We know y = -4

x (-4) = 100

Divide each side by -4

-4x/-4 = 100/-4

x = -25

Answer:

See possible solutions below.

Step-by-step explanation:

The equation x^2 = 36 is a polynomial equation.

It can be solved by using a radical on both sides. The solution is x = +/- 6.

The equation has two solutions. x = -6, 6.

While this is a polynomial equation, it is specifically called a quadratic since the exponent is 2.

The equation x^2 = 36 has two real number solutions: x = 6 and x = -6. Statements that acknowledge both of these solutions as possible would be true.

The equation in question is x^2 = 36. To solve this equation, one must realize that there are two real number solutions since squaring either a positive or negative number will result in a positive number. Taking the square root of both sides of the equation gives us two solutions: x = 6 and x = -6.

Therefore, any statement claiming that there is only one solution is incorrect. The true statements would acknowledge the existence of two solutions, one positive and one negative.

Answer:

Option D

Step-by-step explanation:

The domain of h(x) cannot include 0

h(0) = sqrt (-3) = i sqrt(3)

Which is an imaginary number, and doesn't make sense for the equation to represent imaginary numbers if we are talking about the production of hammers.

The same reasoning can be applied for the second statement.

The domain of the graph should not include zero, beacuse zero people cannot produce any wrenches.

Option D.

Answer:

A  cos C = 12/13

Step-by-step explanation:

cos theta = adjacent side/ hypotenuse

cos C = BC/AC

But we don't know BC, but we can find it using the Pythagorean theorem

a^2 +b^2 = c^2

5^2 +BC^2 = 13^2

25 + BC ^2 =169

Subtract 25 from each side

BC^2 = 169-25

BC ^2 = 144

Taking the square root of each side

BC =12

cos C = 12/13

By applying the Pythagorean theorem, it's determined that a triangle with side lengths of 14, 48, and 50 units is a right-angled triangle, as the sum of the squares of the two shorter sides equals the square of the longest side.

To determine the type of triangle with side lengths of 14, 48, and 50 units, we can use the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

This can be represented by the equation c² = a² + b², where c is the length of the hypotenuse and a and b are the lengths of the other two sides.

In this case, if we consider 50 as the potential hypotenuse (c), and 14 and 48 as the other two sides (a and b), we plug these values into the equation to check: 50² = 14² + 48².

Calculating each side of the equation gives us 2500 = 196 + 2304, which simplifies to 2500 = 2500.

Since both sides of the equation are equal, this confirms that the triangle is indeed a right-angled triangle.

There are nine letters in the word SEVENTEEN:

1 S

4 Es

1 V

2 Ns

1 T

Possible positions:

For the S, any one of the nine positions. That's ⁹C₁ positions.

For the Es, any four of the remaining eight positions. That's ⁸C₄ positions.

For the V, any one of the remaining four positions. That's ⁴C₁ positions.

For the N, any two of the remaining three positions. That's ³C₂ positions.

For the T, only one way  to fill the last position. That's ¹C₁ position.

Total number of positions

= ⁹C₁ × ⁸C₄ × ⁴C₁ × ³C₂ × ¹C₁ = 9 × 70 × 4 × 3 × 1

= 7560

There are 7560 permutations of the letters in the word SEVENTEEN.

Answer:

option B

0.30

Step-by-step explanation:

Given in the question,

probability that a student is a high school junior = P(A) = 0.47

probability that a student is high school junior and owns car = P(A∩B) = 0.14

It is question of conditional probability

Formula to use

Probability = P (A∩B) / P (A)

                  = 0.14 / 0.47

                  = 0.297

                  ≈ 0.30

Answer:

The population means is nothing but the average of this group of items. It is basically arithmetic mean of the group and can be calculated by taking a sum of all the data points and then dividing it by the number of items we have in the group.

A population is defined as a group of individuals of the same species living and interbreeding within a given area. Members of a population often rely on the same resources, are subject to similar environmental constraints, and depend on the availability of other members to persist over time.

Population is the number of people or animals in a particular place. An example of population is over eight million people living in New York City.

Answer:

180 feet

Step-by-step explanation:

√2000 = 44.8

44.8 x 4 =  179.2 = 180 feet

The amount of fencing that would be needed to enclose this square field is  178.88 feet.

A square field would have both the length and the width being equal both of them could be represented as x.

Area of a square = Length x Width

2,000 = x × x

x² = 2,000

x = √2,000

x = 44.72 feet

The fencing needs to go around the field which means it needs to go around the field's perimeter.

Perimeter of Square = Length x 4

= 44.72 x 4

= 178.88 feet

In conclusion, 178.88 feet of fencing would be needed.

[tex]|x-7|=5[/tex]

We know that we need to write our absolute value equation as [tex]|x-b|=c[/tex]. We also know that the solutions must be [tex]x=2[/tex] and [tex]x=12[/tex]. We need to replace those values for [tex]x[/tex] in our absolute value equation, so we can create a system of equations and find the values of  [tex]b[/tex] and [tex]c[/tex].

- For [tex]x=2[/tex]

[tex]|x-b|=c[/tex]

[tex]|2-b|=c[/tex] equation (1)

- For [tex]x=12[/tex]

[tex]|x-b|=c[/tex]

[tex]|12-b|=c[/tex] equation (2)

Now we can solve our system of equations step-by-step:

Step 1. Replace equation (1) in equation (2)

[tex]|12-b|=|2-b|[/tex]

Step 2. Square both sides of the equation to get rid of the absolute values

[tex]|12-b|=|2-b|[/tex]

[tex](12-b)^2=(2-b)^2[/tex]

Step 3. Use the square of a binomial formula: [tex](a-b)^2=a^2-2ab+b^2[/tex] and solve the equation.

For our first binomial, [tex](12-b)^2[/tex], [tex]a=12[/tex] and [tex]b=b[/tex]; for our second binomial, [tex](2-b)^2[/tex], [tex]a=2[/tex] and [tex]b=b[/tex]

[tex](12-b)^2=(2-b)^2[/tex]

[tex]12^2-(2)(12)(b)+b^2=2^2-(2)(2)(b)+b^2[/tex]

[tex]144-24b+b^2=4-4b+b^2[/tex]

[tex]144-24b=4-4b[/tex]

[tex]140=20b[/tex]

[tex]b=\frac{140}{20}[/tex]

[tex]b=7[/tex] equation (3)

Step 4. Replace equation (3) in equation (2) to find the value of [tex]c[/tex]

[tex]|12-b|=c[/tex]

[tex]|12-5|=c[/tex]

[tex]|7|=c[/tex]

[tex]c=7[/tex]

Putting it all together we can conclude that our absolute value equation is [tex]|x-7|=5[/tex]

Step-by-step explanation:

Carlo can use 3 triangles to make a square if the triangles are the correct size and type, such as right-angled triangles, whose hypotenuses can form one side of the square.

Alternatively, he could arrange the triangles to cover half the square's area; however, this would require six triangles, not three.

It is theoretically possible for Carlo to use 3 triangles to make a square, but it requires the right types and sizes of triangles.

A square is a geometrical shape with four equal sides and four right angles.

Triangles, on the other hand, have three sides and can have various angles.

If Carlo is using right-angled triangles, he might arrange them in such a way that the hypotenuses form one side of the square and the other sides of the triangles complete the remaining sides of the square.

However, this would need a bit of creative thinking and specific side lengths for the triangles to ensure the sides of the resulting square are equal.

Another way to approach this is by considering the area of the shapes.

By dissecting the square into smaller squares, and further into triangles, if three triangles can be arranged to form a larger triangle that covers exactly half the area of the square, then two sets of such triangles would be required to form the entire square.

Answer:

x=-9

Step-by-step explanation:

B is unnecessary here, so we can ignore it. The first thing we do in this equation is simplify by adding like terms. 5a-10a=-5a. So, the equation is now -5a=45. To solve a, we need it by itself. To do that, we undo the multiplication by diving both sides of the equation by -5. 45 divided by -5 is -9, and then we have x=-9.
