I need help asap!! (Fractions)

Answer: 10

Step-by-step explanation:

Distance formula = (x2-x1)^2 + (y2-y1)^2

In this circumstance, we have (0,0) and (6,8) as our two points.

(6-0)^2 + (8-0)^2

(6^2) + (8^2)

36 + 64 = 100

Square root the 100.

SQRT of 100 is 10 (perfect square) so your answer is, again, 10.

The coordinates of A and B are-7 and 9. The coordinates of C and D are -4 and 12. AB and CD are not congruent

Congruent refers to objects that are precisely similar in size and shape. The forms stay equal no matter how they are rotated, flipped, or turned. For instance, create two circles with the same radius, cut them out, and stack them.

We'll see that they'll be placed entirely on top of one another and will superimpose one another. This demonstrates that the two circles are similar. Given that they have an equal radius and can be positioned exactly over one another, the circles below are considered to be congruent. "≅" is the sign used to represent the congruence of figures. Since circle A and circle B are similar, we may say the following: Circle B ≅ Circle A.

Lets assume AB and CD are congruent

Then according to Pythagoras theorem

Hypotenuse of AB of right-angled triangle AOB is equal to Hypotenuse of CD of right-angled triangle COD

Hypotenuse AB = Hypotenuse CD

Hypotenuse AB

a² + b² = c²

(-7)² + 9² = c²

49 + 81 = c²

130 = c²

Hypotenuse CD

a² + b² = c²

(-4)² + 12² = c²

16 + 144 = c²

160 = c²

Here, 130 ≠ 160

So, The coordinates of A and B are-7 and 9. The coordinates of C and D are -4 and 12. AB and CD are not congruent

The inequality for the number of cups of lemonade she can buy is :

             0 < c < 5.

Marilyn has $40 to spend in the amusement park.

Admission price = $20

So money left = 40 - 20 = $20

Now she plans to buy a sandwich for $5.

So the money left now will be = 20 - 5 = $15

Price of a cup of lemonade = $3

Marilyn can buy at most $15/3 = 5 cups of lemonade.

She can either choose to not buy a cup of lemonade or can buy at most 5 cups of lemonade.

Spherical geometry would be use in the real world practical applications to navigation. Professions that would need to make it use is astronomy.

These professions make use of spherical geometry for making Spherical conic, Spherical distance, Spherical polyhedron, Half-side formula.

Spherical geometry is the geometry of the two-dimensional surface of a sphere. In this context the word "sphere" refers only to the 2 dimensional surface and other terms like "ball" or "solid sphere" are used for the surface together with its 3-dimensional interior.

An important geometry related to that of the sphere is that of the real projective plane; it is obtained by identifying antipodal points (pairs of opposite points) on the sphere.

Locally, the projective plane has all the properties of spherical geometry, but it has different global properties. In particular, it is non-orientable, or one-sided, and unlike the sphere it cannot be drawn as a surface in 3-dimensional space without intersecting itself.

Answer:

[tex]\dfrac{a+b}{a-b}=-\sqrt{2}[/tex]

Step-by-step explanation:

Given:

[tex]a^2+b^2=6ab[/tex]

[tex]0 < a < b[/tex]

Add 2ab to both sides of the given equation:

[tex]\implies a^2+b^2+2ab=6ab+2ab[/tex]

[tex]\implies a^2+2ab+b^2=8ab[/tex]

Factor the left side:

[tex]\implies (a+b)^2=8ab[/tex]

Subtract 2ab from both sides of the given equation:

[tex]\implies a^2+b^2-2ab=6ab-2ab[/tex]

[tex]\implies a^2-2ab+b^2=4ab[/tex]

Factor the left side:

[tex]\implies (a-b)^2=4ab[/tex]

Therefore:

[tex]\implies \dfrac{(a+b)^2}{(a-b)^2}=\dfrac{8ab}{4ab}[/tex]

[tex]\implies \dfrac{(a+b)^2}{(a-b)^2}=2[/tex]

[tex]\textsf{Apply exponent rule} \quad \dfrac{a^c}{b^c}=\left(\dfrac{a}{b}\right)^c:[/tex]

[tex]\implies \left(\dfrac{a+b}{a-b}\right)^2=2[/tex]

Square root both sides:

[tex]\implies \sqrt{\left(\dfrac{a+b}{a-b}\right)^2}=\sqrt{2}[/tex]

[tex]\implies \dfrac{a+b}{a-b}=\pm\sqrt{2}[/tex]

As 0 < a < b then:

Therefore:

[tex]\implies \dfrac{a+b}{a-b}=\dfrac{+}{-}=-[/tex]

So:

[tex]\implies \dfrac{a+b}{a-b}=-\sqrt{2}[/tex]

The length and width of the rectangular garden is estimated as-

A rectangle's perimeter is the total length and distance of its border across all sides. The perimeter of a rectangular box is a linear measurement that is expressed in meters, feet, cm, or yards. Let us first examine the two primary characteristics of a rectangle.

The perimeter of the rectangle is given as-

Perimeter = 2(length + width)

perimeter= 256

Let the width of the rectangle be x.

Length is 8 feet longer than width, Thus,

length = x+8

Substitute the values in the formula of perimeter;

256 = 2( x+ 8+ x)

256 = 2( 2x + 8)

128= 2x + 8

120= 2x

x=60

Thus, width = 60 ft.

Length = 60 + 8 = 68 ft.

Therefore, the length and width of the rectangular garden is estimated.

The probability would be zero that both the pirate and the captain hit each other's ships.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

Captain Ashley has probability 1/2 of hitting the pirate ship.

Dread pirate Umaima has a 1/3 probability of attacking the Captain's ship if it hasn't already.

The captain must miss if the pirate hits, and the requirement that both hits are not satisfied. The requirement that both hits cannot be satisfied if the pirate misses.

Therefore, the probability would be zero that both the pirate and the Captain hit each other's ships.

The rate of change/slope of the ramp’s incline is found to be 3.

A line's slope is defined as the change in y coordinate in relation to a change in x coordinate.

m = Δy/Δx

where, m is the slope

And, tan θ = Δy/Δx

Such an tan θ is also known as the line's slope.

The slope of a line could be determined by calculating using only two straight line points. The slope of line formula could then be used with two point coordinates.

Now, in response to the question;

To link a driveway to a front door, a ramp with a constant incline is built.

The ramp's height  y₁ is 12 inches at a point 4 feet from of the driveway x₁.

The height y₂ of the ramp is 18 inches at a point 6 feet from of the driveway x₂.

The incline of the ramp's rate of change is given by:

Slope = m = tan θ = (y₂ - y₁)/(x₂ - x₁)

The values given in the question;

(x₁, y₁) = (4, 12) and,

(x₂, y₂) = (6, 18)

Put the values in the formula of the slope;

Slope = m = (18 - 12)/(6 - 4)

m = 6/2

m = 3

Therefore the rate of change also called as ramp’s incline is calculated as 3.

Segment PS in the scaled copy corresponds to segment AD in polygon ABCD in polygon PQRS. They are similar in appearance and appear in the same location.

A polygon is a two-dimensional flat shape with straight, fully closed sides. Straight, not curved, sides are required. Polygons, on the other hand, can have any number of sides.

Polygon is derived from the Greek word "polugonos." It has evolved into the term "polygon" over time. The term "polygon" means "many" and "gon" means "angled." This is due to the fact that a polygon has numerous angles and corners within its shape.

The Greeks may have been the first to recognize polygons, as there are numerous examples of them recognizing polygons such as the pentagram in their ancient art and writings.

The value of the expression [tex]\lim_{x \to A} \frac{xcot(A)-Acot(x)}{x-A}[/tex] is [tex]cot(A)+\frac{A}{sin^{2}A}[/tex].

The value that a function approaches when the input approaches a certain value is known as a limit. Calculus and mathematical analysis are not possible without limits, which are also required to determine derivatives, continuity, and integrals.

Mathematical expressions consist of at least two variables or numbers, at least one arithmetic operation, and a statement. It's possible to divide, multiply, add, or subtract with this mathematical operation.

Consider the expression,

[tex]\lim_{x \to A} \frac{xcot(A)-Acot(x)}{x-A}[/tex]

Adding and subtracting Acot(A) and A common in the numerator,

[tex]\lim_{x \to A} \frac{xcot(A)-Acot(A)+Acot(A)-Acot(x)}{x-A}[/tex]

Taking cot(A) common,

[tex]\lim_{x \to A} \frac{cot(A)(x-A)+A(cot(A)-cot(x))}{x-A}[/tex]

[tex]\lim_{x \to A} cot(A) + \frac{A(cot(A)-cot(x)}{x-A}[/tex]

Now, using the identity:

cot x = cos x / sin x

[tex]\lim_{x \to A} cot(A) + \frac{A(\frac{cos(A)}{sin(A)} -\frac{cos(x)}{sin(x)}) }{x-A}[/tex]

[tex]\lim_{x \to A} cot(A) + \frac{A}{x-A}(\frac{cos(A)sin(x)-cos(x)sin(A) }{sin(A)sin(x)})[/tex]

By using the identity, sin ( a - b ) = sin(a)cos(b) - sin(b)cos(a)

[tex]\lim_{x \to A} cot(A) + \frac{A}{x-A}(\frac{sin(x-A)}{sin(A)sin(x)})[/tex]

[tex]\lim_{x \to A} cot(A) + \frac{A}{x-A}(\frac{sin(x-A)}{sin(A)sin(x)})=\lim_{x \to A} cot(A) +\lim_{x \to A} \frac{sin(x-A)}{(x-A)}\frac{A}{sin^{2}A}[/tex]

The locations of the vertices of the dilated figures are (48,16), (32,40), and (8,24).

This problem can be solved by using the concept of scale factor. Scale factor is useful in finding proportional measurements.

Proportion implies having the same ratio.

Scale factor can be defined as the ratio of the measurement of the model to the measurement of the actual form in the simplest form. In other words, the ratio of any two corresponding lengths in two similar geometric figures is called a scale factor.

If the scale factor is more than 1, that is, scale factor > 1,

then it is an enlargement,

If the scale factor is less than 1, that is, scale factor < 1,

then it is a reduction.

We can obtain the answer by multiplying the given coordinates, first by a scale factor of 4 and then by a scale factor of 2/3.

(18,6) => (18x4, 6x4) => (72,24) => (72x2/3, 24x2/3) => (48,16)

(12,15) => (12x4, 15x4) => (48,60) => (48x2/3, 60x2/3) => (32,40)

(3,9) => (3x4, 9x4) => (12,36) => (12x2/3, 36x2/3) => (8,24)

Therefore, using the concept of scale factor, we get the locations of the vertices of the dilated figures as (48,16), (32,40), and (8,24).
