Help!! 20 points ASAP math

Answer: what are you talking about????????

Step-by-step explanation:

Answer: flight to NYC

distance: 740 rate: 495+x time: 740/495+x

flight home:

distance: 740 rate: 495-x time: 740/495-x

Step-by-step explanation: the plane is flying with the wind when flying to NYC so the planes speed, or rate, can be modeled as 495+x

on the flight back home plane is flying against the wind so the planes speed, or rate, can be modeled as 495-x

multiply across the table to find the time each journey will take by using the equation time=distance/rate. Hope this helped :)

Answer:

n = 18

Step-by-step explanation:

[tex] \frac{6}{5} = \frac{n}{15} [/tex]

Cross multiply and simplify

[tex]6 \times 15 = 5 \times n \\ 90 = 5n[/tex]

Divide both sides of the equation by 5

[tex] \frac{90}{5} = \frac{5n}{5} [/tex]

Simplify : Cross cancel common factor: 5

[tex]18 = n \\ n = 18[/tex]

The region in the x-y plane is the set of points

[tex]R=\{(x,y)\mid0\le x\le 1,x^2\le y\le\sqrt x\}[/tex]

The height of the solid falls between the x-y plane (for which z = 0) and the equation of the plane, z = 3x + 2y.

So the volume is

[tex]\displaystyle\int_0^1\int_{x^2}^{\sqrt x}\int_0^{3x+2y}\mathrm dz\,\mathrm dy\,\mathrm dx[/tex]

[tex]=\displaystyle\int_0^1\int_{x^2}^{\sqrt x}(3x+2y)\mathrm dy\,\mathrm dx[/tex]

[tex]=\displaystyle\int_0^1(3x^{3/2}+x-3x^3-x^4)\,\mathrm dx[/tex]

[tex]=\displaystyle\frac65+\frac12-\frac34-\frac15=\boxed{\dfrac34}[/tex]

Answer:

In the 8% option , $5,000 should be invested

In the 12% option, $15,000 should be invested

Step-by-step explanation:

Let’s start with the total return.

Since the total return expected is 11%, the amount expected to be returned will be;

11/100 * 20,000 = $2,200

Now, let the amount invested at 8% interest be $x while the amount invested at 12% interest be $y

Mathematically;

x + y = 20,000 ••••••(i)

Now let’s work with the interest part;

On the 8% part, amount of interest expected is 8/100 * x

on the 12% part, amount of interest expected is 12/100 * x

8% of $x + 12% of $y = 2,200

Writing this fully mathematically, we have;

(8/100 * x) + (12/100 * y) = 2,200

8x/100 + 12y/100 = 2,200

Multiply through by 100

8x + 12y = 220,000 ••••••(ii)

Now we have two equations to solve simultaneously;

x + y = 20,000

8x + 12y = 220,000

From i, x = 20,000-y

Substitute this into ii

8(20,000-y) + 12y = 220,000

160,000-8y + 12y = 220,000

4y = 220,000 - 160,000

4y = 60,000

y = 60,000/4

y = $15,000

x = 20,000 -y

x = 20,000 - 15,000

x = $5,000

The answer is

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(3, 5.25) and (3, –8.75)

The distance between them is

[tex]d = \sqrt{ ({3 - 3})^{2} + ({5.25 + 8.75})^{2} } \\ = \sqrt{ {0}^{2} + {14}^{2} } \\ = \sqrt{196} \: \: \: \: \: \: \: \: \: \: \\ = 14 \: \: \: \: \: \: [/tex]

We have the final answer as

The number 25w^9x^6 - 4 is not factorable.

Answer:

74°F

Step-by-step explanation:

In order to find the average of a certain amount of numbers, you add those numbers together and divide by how many numbers there are. In this case, you would reverse that method to find the last number. We know that there were four readings, and we have three of them and the average. Multiply the average (84.75) by the number of readings (4), and you get the sum of all the readings (339). Then you subtract each of the readings that you already know to isolate the last reading. 339 - 112 (first reading) = 227, 227 - 68 (second reading) = 159, and 159 - 85 (fourth reading) = 74. Therefore, the third reading must be 74.

Answer:

1. Statisticians and operations research analysts.

2. 167,582.3 persons.

3. 40%.

4. Pharmacist

Step-by-step explanation:

1.  According to data from the U.S. Bureau of Labor Statistics,  Statisticians and Operations Research analysts are among the fastest-growing occupations in terms of their percent growth, having high projected growth rates of 33.8 percent and 30.2 percent.

2. People who are expected to work as Mathematicians by 2026 are projected to grow up to 27.9 percent (167,582.3 persons).

3. About 40% of the fastest-growing careers are in the health & human services industry. This is the case because as the human population continues to increase, the need for healthcare providers will increase rapidly.

4. Considering the lower projection of 22% for this career,  it gives better prospects for getting employment due to the limited supply of Pharmacists.

Answer:

The equation of the line is:

[tex]y = -4\,x +16[/tex]

Step-by-step explanation:

A line perpendicular to the given one is going to have a slope equal to the opposite of the reciprocal of 1/4. That is the slope of the new line will be "-4".

Now we write the point-slope form for a line using the info provided of slope -4 and point (5, -4):

[tex]y-y_0=m\,(x-x_0)\\y - (-4) = -4 \,(x-5)\\y+4 = -4\,x +20\\y = -4\,x +16[/tex]

Answer:

y = -4x + 16

Step-by-step explanation:

For questions like this, I would first find the slope of the line that we are trying to find the equation for. To do this, I would use the line y = 1/4x - 2 and find the slope of a line that would be perpendicular to it. Taking the negative reciprocal of the slope of y = 1/4x - 2 will do just that.

By looking at the equation y = 1/4x - 2, we can see that the slope of the line is 1/4. The negative reciprocal of 1/4 would be -4, which would be the slope of the line whose equation we are trying to find.

Since we have a point on the line, and we now have the slope of the line, we can now make an equation for the line in point-slope form:

y + 4 = -4(x - 5)

Now while this is an equation for the line, lets try to get it into slope-intercept form:

y + 4 = -4(x - 5)

Distribute the -4 on the right side of the equation.

y + 4 = -4x + 20

Subtract 4 from both sides.

y = -4x + 16

And now we have the equation of the line in slope-intercept form.

I hope you find my answer helpful.

There would be no x intercepts (I think)

And the y intercept would be (0,7)

So the vertex would be (-6,3)
