If the part shown is ¾ of a flag, what could the whole flag look like? Draw a picture and write a fraction to represent the whole.

​

Answer:

00.300

Step-by-step explanation:

What value does the 3 represent in the number 16.344

The 3 in the number 16.344 represents 0.003, since it's located on the third decimal place. It contributes three-thousandths to the total value. The position of the number changes the value it represents.

The value of 3 in the number 16.344 is represented as 0.003 in decimal place value. This is because it is situated in the third digit after the decimal point, signifying that it contributes the amount equal to three thousandths (0.003) to the total value of the number. For example, in using the concept of Six significant figures, we can say the number 16.344 has five significant figures, that is, the digits that give us precise information about the magnitude of the number - these digits being 1, 6, 3, 4 and 4.

It's also worthwhile to note that the placement of the digit 3 in the number 16.344 is different from a 3 that is located at other decimal places. For instance, if we look at the number 16.3443, the second 3 after the decimal point represents three ten-thousandths (0.0003) contribution to the total value of the number.

Answer:

The last one

Step-by-step explanation:

volume is v= [tex]\pi r^{2} h[/tex] . this means volume is mathematical number pi, times the (radius squared), times the height. the radius is marked at the yellow line, and the height on the side. this means you would have v = [tex]\pi[/tex][tex](x+2)^{2}[/tex][tex](3x+8)[/tex]

first, lets work out [tex](x+2)^{2}[/tex]. we can rewrite this as (x+2)(x+2). we are going to use a system called FOIL. this stands for First Outside Inside Last. This means we are going to take the first number from both and multiply them together, then the outside, inside, and last. so, for first, we will multiply x and x and then we have [tex]x^{2}[/tex], for outside we multiply x and 2 and we get [tex]2x[/tex], for inside we multiply 2 and x and we get [tex]2x[/tex], and for last we multiply 2 and 2 and we get [tex]4[/tex]. then we add all these together. [tex]x^{2} + 2x + 2x + 4[/tex]. then simplify like terms to get

[tex]x^{2} + 4x + 4[/tex]. now, we can't forget about our times [tex]\pi[/tex] and (3x+8)

this means we have to multiply [tex]x^{2} + 4x + 4[/tex] by those two.

it would look like this: ([tex]x^{2} + 4x + 4[/tex])(3x+8)[tex]\pi[/tex]

so now we are going to multiply the other two sets of parentheses

we multiply each number from the first set to each number in the second set.

To prove ABCD is a rhombus, showing that all sides of parallelogram ABCD are equal in length would suffice.

If ABCD is a parallelogram, to prove that it is a rhombus, a statement that would suffice is that all four sides of the parallelogram are of equal length.

This is because a rhombus is defined as a parallelogram with four congruent sides. If any one of its diagonals bisects an angle of the parallelogram, or its diagonals are perpendicular, or its diagonals are of the same length, these conditions would not exclusively prove it to be a rhombus, although they are properties of a rhombus. However, the definition of a rhombus centers on the equality of all sides.

Equal adjacent angles would not necessarily mean that all sides are equal, which is a requirement for a rhombus.

The correct option is (B).

To prove that a parallelogram is a rhombus, you need to show that all four sides are of equal length. A parallelogram has opposite sides that are equal and parallel, but for it to be a rhombus, every side must be equal in length to every other side.

The statement options you might have in your image could be something like:

a. Diagonals are perpendicular (AC ⊥ BD)

b. Adjacent angles are equal (∠ABC ≅ ∠CDA)

c. One pair of opposite sides are equal (AB ≅ CD)

d. Diagonals are equal (AC ≅ BD)

From these options:

- Option a: If the diagonals are perpendicular, it's an indication that the parallelogram could be a rhombus, but it's not conclusive proof because a rectangle also has perpendicular diagonals.

- Option b: Equal adjacent angles would not necessarily mean that all sides are equal, which is a requirement for a rhombus.

- Option c: Having one pair of opposite sides that are equal is already a property of a parallelogram and does not prove it's a rhombus.

- Option d: Equal diagonals would be a property of a rectangle, not necessarily a rhombus.

The conclusive proof that a parallelogram is a rhombus would be if you can show that all sides are of equal length (not provided in the typical options above), or if the diagonals are perpendicular and bisect each other into equal segments. This latter property is unique to a rhombus among parallelograms. If this were one of the choices, it would be the correct answer.

Since I can't see the options, please review them and look for the one that indicates all four sides are of equal length or that the diagonals bisect each other into equal segments and are perpendicular. That would be the correct choice to prove the parallelogram is a rhombus.

Answer:

Step-by-step explanation:

Answer:

-1 is the smallest according to this question

minimum value of the quadratic function f(x) = x² - 2x + 7 is at x=1 & is (1, 6).

Step-by-step explanation:

Here we have ,  f(x) = x² - 2x + 7 or [tex]f(x) = x^2 - 2x + 7[/tex] . We need to find the minimum value of f(x) for which we need to differentiate it one time and equate it to zero . Value of x at which first differentiation of f(x) is zero will be the minimum value of function  . Let's solve this:

[tex]f(x) = x^2 - 2x + 7[/tex]

⇒ [tex]f(x) = x^2 - 2x + 7[/tex]

⇒ [tex]\frac{df(x)}{dx} = \frac{d(x^2 - 2x + 7)}{dx}[/tex]

⇒ [tex]\frac{df(x)}{dx} = \frac{d(x^2)}{dx} - \frac{d(2x)}{dx} + \frac{d(7)}{dx}[/tex]

⇒ [tex]\frac{df(x)}{dx} = 2x-2 = 0[/tex]

⇒ [tex]2x-2 = 0[/tex]

⇒ [tex]x =1[/tex]

Now, value of function at x=1 is :

[tex]f(x) = x^2 - 2x + 7[/tex]

⇒ [tex]f(x) = x^2 - 2x + 7[/tex]

⇒ [tex]f(1) = 1^2 - 2(1) + 7[/tex]

⇒ [tex]f(1) = 8- 2[/tex]

⇒ [tex]f(1) = 6[/tex]

Therefore, minimum value of the quadratic function f(x) = x² - 2x + 7 is at x=1 & is (1, 6).

The minimum value of the quadratic function f(x) = x² - 2x + 7 is 6, which occurs at x = 1, as determined by finding the vertex of the parabola.

The minimum value of the quadratic function f(x) = x² - 2x + 7 can be determined by finding the vertex of the parabola represented by the function. This is because the graph of a quadratic function is a parabola, and if the coefficient of the x² term is positive, the parabola opens upwards and the vertex represents the minimum point.

To find the vertex, use the formula -b/2a to determine the x-coordinate of the vertex. For the function f(x), the value of 'a' is 1 and 'b' is -2. Substituting these values gives us the x-coordinate of the vertex as x = -(-2)/(2*1) = 1. Substituting x = 1 back into the function f(x), we get the y-coordinate of the vertex, which is the minimum value of the function: f(1) = (1)² - 2*(1) + 7 = 6.

Therefore, the minimum value of the quadratic function f(x) is 6, occurring at x = 1.

Answer:

(- 8, - 4 )

Step-by-step explanation:

Under a counterclockwise rotation about the origin of 90°

a point (x, y ) → (- y, x ), thus

(- 4, 8 ) → (- 8, - 4 )

When we say "a is at most b" we mean that "a is less than or equal to b" or "a is not greater than b". So let's solve this problem as follows:

Step 1. Twice the difference of a number and 2

Let's call that unknown number as n. Then, twice the difference of a number and 2 is:

[tex]2(n-2)[/tex]

Step 2. Twice the difference of a number and 2 is at most -27

[tex]2(n-2)\leq -27[/tex]

_________________________________________

So the mathematical form of the statement twice the difference of a number and 2 is at most -27 is:

[tex]\boxed{2(n-2)\leq -27}[/tex]

Step-by-step explanation:

We have the following figure attached as shown below.

Now, this triangular prism have 2 similar right angled surfaces and 3 rectangular surfaces , Let's calculate area for all of them:

2 similar right angled surfaces

We know that area of triangle = [tex]\frac{1}{2} b(h)[/tex]

⇒ [tex]area = \frac{1}{2} b(h)[/tex]

⇒ [tex]area = \frac{1}{2} (3.6)(7.7)[/tex]

⇒ [tex]area = 13.86km^{2}[/tex]

But there 2 such surfaces so , [tex]area = 2(13.86) = 27.72km^2[/tex]

3 rectangular surfaces

Area of rectangle = [tex]length(breadth)[/tex]

⇒ [tex]area_1 = 3.6(1.8)[/tex]

⇒ [tex]area_1 = 6.48km^2[/tex]

⇒ [tex]area_2= 7.7(1.8)[/tex]

⇒ [tex]area_2 = 13.86km^2[/tex]

⇒ [tex]area_3 = 8.5(1.8)[/tex]

⇒ [tex]area_2 = 15.3km^2[/tex]

Total area =[tex]6.48 + 13.86 + 15.3 = 35.64km^2[/tex]

Adding area of 2 similar right angled surfaces & 3 rectangular surfaces:

[tex]Area = 27.72+35.64 = 63.36km^2[/tex] = [tex]63.4km^2[/tex]

Correct option B)[tex]63.4km^2[/tex] .

1. Both [tex]x^{2}[/tex] and 64 are perfect squares, meaning [tex]16b[/tex] is twice the product of x and 8. Since all signs are positive, the equation would be: [tex](a+b)^{2} =a^{2} +2ab+b^{2}[/tex]. Let [tex]a=x[/tex] and [tex]b=8[/tex]. Answer: [tex](b+8)^{2}[/tex] or [tex](b+8)(b+8)[/tex].

2. Since -3 is a factor of all 3 terms, factor out the -3 which makes,  [tex]-3(k^{2} +5k^{2} -2k)[/tex] . K is also a common factor, so you would factor that out too, [tex]-3k(k^{2} -5k-2)[/tex]. Then simply, find the two factors whose product is -2 and whose sum is -5. Answer: [tex]-3k(k^{2} -5k+2)[/tex].

3. By factoring [tex]3x^{2} -16x+5[/tex], you would break the expressions in the group=[tex](3x^{2} -x)+(-15x+5)[/tex]. Then, factor out "x" from [tex]3x^{2} -x: x(3x-1)[/tex]. Factor out "5" from [tex]-15x+5:-5(3x-1)[/tex] = [tex]x(3x-1)-5(3x-1)[/tex]. Finally, factor out the common term "3x-1" = [tex](3x-1)(x-5)[/tex]

Answer:

Yes.

Step-by-step explanation:

Note that  15^2 = 122^ + 9^2  ( 225 = 144 + 81 = 225).

So by the Inverse of Pythagoras Theorem  it is a right triangle.

The given values of side makes a proper right angle triangle.

To determine if the three given side lengths, 9, 12, and 15, form a right triangle, we can use the Pythagorean theorem.

The Pythagorean theorem states that in a right 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.

Let's check if this holds true for the given side lengths:

[tex]9^2 + 12^2 = 81 + 144 = 225\\\\15^2 = 225[/tex]

The sum of the squares of the two shorter sides, 9 and 12, is equal to the square of the longest side, 15. This satisfies the Pythagorean theorem.

Therefore, the side lengths 9, 12, and 15 do form a right triangle.

Answer:

y = 9

Step-by-step explanation:

Calculate the slope m of line k using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (5, 8) and (x₂, y₂ ) = (2, y)

m = [tex]\frac{y-8}{2-5}[/tex] = [tex]\frac{y-8}{-3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex]

The slope of line l is m = 3, thus slope of line k is

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

Equating the 2 slopes for line k

[tex]\frac{y-8}{-3}[/tex] = - [tex]\frac{1}{3}[/tex] ( multiply both sides by - 3 )

y - 8 = 1 ( add 8 to both sides )

y = 9

To find the value of y, we can use the fact that the slopes of Perpendicular lines are negative reciprocals of each other. Using the given information and equations, we can solve for y.

To determine the value of y, we can use the fact that the slopes of perpendicular lines are negative reciprocals of each other. Since line l has a slope of 3, the slope of line k would be -1/3. We can use the slope-intercept form, y = mx + b, to find the equation of line k.

Substituting the coordinates (5, 8) and the slope -1/3 into the equation, we can solve for y.

Using the point-slope form, y - y1 = m(x - x1), where (x1, y1) is the given point (2, y). We can rearrange this equation to get y = mx + b form, substitute the values, and solve for y to find the value of y.
