Calculate the distance using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = B(0, 0) and (x₂, y₂ ) = ([tex]\frac{\sqrt{6} }{2}[/tex], [tex]\frac{\sqrt{58} }{2}[/tex] )

AB = [tex]\sqrt{((\frac{\sqrt{6} }{2})^2 }[/tex] + [tex]\{(\frac{\sqrt{58} }{2})^2 }[/tex]

The product of 4127 and 28324 is 116884748.

To find the product of 4127 and 28324:

Write down the numbers vertically aligning the digits:

4127 x 28324

Multiply each digit of the second number by the entire first number, remembering to shift each subsequent multiplication one place to the left:

4127 × 4 = 16508

4127 × 2 = 8254 (shift one place to the left, becomes 82540)

4127 × 3 = 12381 (shift two places to the left, becomes 1238100)

4127 × 8 = 33016 (shift three places to the left, becomes 33016000)

4127 × 2 = 8254 (shift four places to the left, becomes 82540000)

Add all these partial products together:

16508 + 82540 +1238100 +33016000 +82540000

= 116884748

So, the product of 4127 and 28324 is 116884748.

Answer:

21.29 milliliters

Step-by-step explanation:

First find how much water is need for 1 gram of stone by dividing both numbers by 263. Then multiplying both numbers by 70.

Grams : Milliliters

263       80

1           : 0.3042 (Rounded to 4 decimal places)

70        : 21.29 (Rounded to 2 decimal places)

The amount of water needed when using 70 grams of dental stone powder is approximately 21.29 milliliters. This is based on the ratio of stone powder to water in the original mixture.

The question is asking for the calculation of the amount of water needed if 70 grams of dental stone powder is used. This can be resolved by determining the ratio of water to dental stone powder in the initial mixture, and then applying this ratio to the lesser quantity of 70 grams. In the original mixture, there are 263 grams of dental stone powder to 80 milliliters of water which simplifies to approximately 1 gram to 0.3042 milliliters of water. Therefore, if you use 70 grams of stone powder, you multiply 70 grams by 0.3042 milliliters/g, which equates to approximately 21.29 milliliters of water.

Anderson was unable to capitalize on her invention, and other companies were able to profit from her invention without paying her.

The sequence of events that explains why Anderson did not make any money from her patent is as follows:

The image of Mary Anderson and the First Windshield Wipers confirms this sequence of events. The image shows Anderson with a model of her windshield wiper invention. The text below the image states that Anderson "failed to sell her patent to any manufacturer" and that "her patent expired in 1920 without her making any money from her invention."

In addition to the information in the image, we can also infer that Anderson did not make any money from her patent because she did not have the business acumen or resources to bring her invention to market. She was a single woman with no business experience. She also did not have the financial resources to manufacture and market her invention on her own.

Roots are complex numbers

Step-by-step explanation:

we know that

In a quadratic equation of the form [tex]ax^{2} +bx+c=0[/tex]

The discriminant is equal to  [tex]b^{2} -4ac[/tex]

If [tex]b^{2} -4ac=0[/tex] -----> The equation has only one real root

If [tex]b^{2} -4ac>0[/tex] -----> The equation has two real roots

If [tex]b^{2} -4ac<0[/tex] -----> The equation has complex roots

In this problem the discriminant is -8

so

-8 < 0

Step-by-step explanation:

Distribute the 3 with the parenthesis to make the new equation -2=12x-9+5.

Combine like terms. -2=12x-4.

Move -4 to other side. -6=12x.

Divide by -6. x=-2

Answer:

1) [tex]2,549,786\ people \approx3,000,000\ people[/tex]

2) [tex]3*10^6[/tex]

Step-by-step explanation:

1) To round a number to the nearest million, you must look at the digit located in the hundred thousands place. If this is greater than or equal to 5 you must round up, and if this is less than 5, you must round down.

In this case you know that the city has a population of [tex]2,549,786\ people[/tex].

You can notice that the digit located in the hundred thousands place is 5, therefore, you must round up:

[tex]2,549,786\ people \approx3,000,000\ people[/tex]

2) Scientific notation has the following form:

[tex]a*10^n[/tex]

Where "a" must be a number from 1 to 10 but not including 10 and "n" must be an integer.

To express [tex]3,000,000[/tex] in Scientific notation, the decimal point must be moved 6 places to the left; therefore, the exponent will be positive.

Then:

[tex]=3*10^6[/tex]

Answer:

After 5 years : ( n + 5 ) years !

Before 5 years : ( n - 5 )

Step-by-step explanation:

Given the age of Mary is n years old

After 5 years , She must be 5 years more from now so,

Her age will be ( n + 5 ) years after 5 years from now !

Also, 5 years ago she must be 5 years less than from now ,

So, her age 5 years ago was ( n - 5 ) years !

To represent Mary's age 5 years from now, the expression 'n + 5' is used. To represent her age 5 years ago, the expression 'n - 5' is used.

To represent Mary's age 5 years from now, we can use the expression n + 5. This is because we add 5 to her current age, represented by 'n', to find her age in the future.

To represent Mary's age 5 years ago, we can use the expression n - 5. This is because we subtract 5 from her current age, represented by 'n', to find her age in the past.

The domain of the heart rate function h(t) for a runner who completed a 10-mile run in 112 minutes is [0, 112] in interval notation.

In this scenario, the domain of the function h(t) is the time duration during which the runner is running. Thus, since the runner completed the 10-mile run in 112 minutes, the domain is from 0 (the start of the run) to 112 (the end of the run). We represent this in interval notation as [0, 112]. The square brackets indicate that the endpoints are included in the domain. So, the domain of the function h(t) in this context is [0, 112].

Answer:

The coordinates of the vertex of the graph are (-2, -9).

Step-by-step explanation:

The quadratic function is described by the standard equation   The graph of a quadratic function is called a parabola.

We have the quadratic function

We identify the coefficients a, b, and c. For this equation,

The axis of symmetry is , i.e.,  Thus, the statement in the question for the symmetry axis x = -2 is correct.

The vertex (or turning point) is  where   or

The parabola opens upward because a > 0, resulting in a vertex that is a minimum.

Finding the minimum value is as follows:

Therefore, the coordinates of the vertex of the graph are (h, k), i.e.,

the vertex of the graph is (-2, -9)
