Which number line represents the solution set for the inequality –x ≥ 4?

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.

Amount of population Decay A= Pe^-re

A= accumulated amount

r=rate ⇒3.1% ⇒ 3.1/100. ⇒0.031

t = elapsed time ⇒ 4

A=40000e ^0.031(4) ⇒A=40000 ^0.124⇒A=40000/e^0.124

A  ≈35335.194 ⇒ A ≈ 35335.(rounded up

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:

Step-by-step explanation:

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.

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:

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=-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.

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]

the equation for your answer is y=mx+b

Answer:

[tex]y=-\frac{1}{4} x-6[/tex]

Step-by-step explanation:

Slope-Intercept Form

[tex]y=mx+b[/tex]

y: range

m: slope

x: domain

b: y-intercept

We can see that the line intersects at [tex](0,-6)[/tex], which is the y-intercept. We now have:

[tex]y=mx-6[/tex]

To find the slope, we need to start at the y-intercept. We need to find another nice point we can use. There is a nice point at [tex](4,-7)[/tex]. Start at the y-intercept, go down one unit, and go right four units. By doing that, you just found your slope.

[tex]y=-\frac{1}{4} x-6[/tex]

We know it is negative because as the x values become greater, the y values become less.

Step-by-step explanation:

if you simplify it all then you have to flip creating 50 = 49

The variable got eliminated. Then inequality –7(3x – 7) + 21x ≥ 50 has no solution.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

The inequality is given below.

–7(3x – 7) + 21x ≥ 50

Simplify the inequality, then we have

–7(3x – 7) + 21x ≥ 50

–21x + 49 + 21x ≥ 50

–21x + 49 + 21x ≥ 50

–21x + 21 ≥ 1

The variable got eliminated. Then inequality –7(3x – 7) + 21x ≥ 50 has no solution.

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

Answer:

Greater than 5 and less than 6

Step-by-step explanation:

To find the square root of 34, find the closest perfect squares to it.

The closest perfect squares are 25 and 36

The square root of 25 is 5

The square root of 36 is 6

Therefore, the square root of 34 is greater than 5, and ess than 6.

(It's in between 5 & 6).

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.
