The coordinates of the midpoint are 22,-4.

A location that is halfway between two other points is considered to be a line segment's midway. The distance between the midway and each endpoint is the same.

Given that the coordinates of the midpoint of a segment with the given points. 16,5 and 28,-13.

The midpoint will be calculated as:-

M = ( x₁ + x₂ ) / 2 , ( y₁ + y₂ ) / 2 ,

M = ( 16  + 28 ) / 2 , ( 5 - 13  ) / 2 ,

M = ( 44 ) / 2 , ( -8 ) / 2 ,

M = 22 , -4

Therefore, the coordinates of the midpoint are 22,-4.

Answer:

P" = (-2, -1)

Step-by-step explanation:

When a point P(x, y) is rotated 180° clockwise or anticlockwise the coordinates of the new point P'(x', y') become (-x, -y). The rotated point has coordinates which are negative of the original coordinates

When a point is translated (a, b) then new coordinates become (x + a,, y + b)

Here point P is (1, -1)

Rotation by 180° ⇒ rotated point P'(-1, 1)

If we translate P' by (-1, -2) translated point

P" has coordinates x" = -1 -1 = -2 and y" = 1 -2 = -1

So coordinates of P" are (-2, -1)

Given the total number of notes is eight and their value total is $550, then you have 5 notes of $50 and 3 notes of $100

As per the question statement, You have [tex]x[/tex] number of $50 notes and [tex]y[/tex] number of $100 notes. Their total value of $550 and total number of notes are eight. We are supposed to calculate the value of [tex]x[/tex] & [tex]y[/tex]

This question is a classic example of how to form and solve linear equations. For solving this, we will have two equations, both in two variable x and y.

As we have total 8 notes, therefore,

[tex]x+y=8[/tex]

And their total value is 550, therefore,

[tex]x*50+y*100=550[/tex]

From 1st equation we get, [tex]y=8-x[/tex]

substituting this in another equation, we get

[tex]x*50+(8-x)(100)=550\\50x+800-100x=550\\800-50x=550\\50x=250\\x=5[/tex]

Solving for y, we get

[tex]y=8-x\\x=5\\y=8-5\\y=3[/tex]

Therefore we have 5 notes of $50 i.e., [tex]x=5[/tex] and 3 notes of $100 i.e., [tex]y=3[/tex]

Answer:

Step-by-step explanation:

We cannot tell what kind of proportionality to assume here.

If x and y are directly proportional, multiplying one by a factor will multiply the other by the same factor.

If x and y are inversely proportional, multiplying one by a factor will divide the other by the same factor.

__

1. Given (x, y) = (2, 24). Direct: y = 9/2(24) = 108.

  Inverse: y = 2/9(24) = 16/3

__

2. Given (x, y) = (25, 18). Direct: y = 30/25(18) = 108/5.

  Inverse: y = 25/30(18) = 15.

3. Given (x, y) = (1, 10). Direct: y = 20/1(10) = 200.

An inequality can be defined as a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following arguments:

In this exercise, you're required to describe the score which this ski jumper must earn on the second jump to beat his or her competitor. Therefore, let x represent the score of his or her second acrobatic ski jump.

Based on the competitor's score of 119.8 in the second jump, this ski jumper must earn the following score represented by this inequality:

x > 119.8

From the table (see attachment), we can logically deduce that the competitor's score in the first ski jump is equal to 117.1. This ultimately implies that, the ski jumper's score can be modeled by this inequality:

x > 117.1

In this context, we can reasonably infer and logically deduce that both the coach and the teammate are correct because a score of "118.4" and "117.5" are greater than a score of "117.1."

Answer:

43%

Step-by-step explanation:

There are 39 girls. 21 of them like biology. 11 out of 34 who like chemistry are girls.

No. of girls who prefer biology = 21

There are (100-39) boys. 16 of them like physics. (34-11) of them like chemistry.

No. of boys who prefer biology = 100-39-16-34+11

                                                    = 22

Percentage of students who prefer biology = [tex]\frac{21+22}{100}[/tex] × 100%

                                                                        = [tex]\frac{43}{100}[/tex] × 100%

Hi there!

The error in using the diagram to find x in the solving is that they only picked two angles and equated to 180° which is wrong. You'll find out that their final value for x contains a decimal point which should never be in angles.

The above diagram is a revolution (360°) or angle at a point, so all the angles have to be considered and equated to 360° and NOT 180°

Below is the corrected solving.

[tex]13x + 45 + 12x - 40 + 19x + 3 + 6x + 2 = 360[/tex]

(reason: angles at a point = 360°)

Collect like terms, and make x the subject of formula.

[tex]⟹50x + 10 = 360[/tex]

[tex]⟹50x = 360 - 10[/tex]

[tex]⟹50x = 350[/tex]

Now, divide both sides by 50 to find the value of x.

[tex] \frac{50x}{50} = \frac{350}{50} [/tex]

Therefore:

[tex]x = 7[/tex]

Answer: for b: function one has a greater rate of change

Step-by-step explanation: sorry i don't know the first one

Answer:

a) -2 and 4, b) function 2

Step-by-step explanation:

Rate of change is the same thing as slope. For the first function, the table, we can use two of the points and the slope formula. I'll use (-1,3) and (-2,5). Remember the slope formula:

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

Plug the points in:

[tex]m=\frac{5-3}{-2-(-1)}\\m=\frac{2}{-1}\\m=-2[/tex]

(Remember that subtracting a negative = adding. I look at it like the two 'minus' signs form one plus sign, if that helps)

So the slope of function 1 is -2.

We can do the same thing with the second function. Two points that I notice on the graph are (-1,0) and (0,4). Let's use the same slope formula.

[tex]m=\frac{4-0}{0-(-1)}\\m=\frac{4}{1}\\m=4[/tex]

And the slope of function 2 is 4. That answers the first part. The second part asks about rate of change.

Function 2 has a greater rate of change, since 4>-2.

Hope this helps!

Answer:

balloons= 9

candles= 8

Step-by-step explanation:

let the number of balloons be x

and candles be y

So

15x+8y=192----------1

x+y=17--------------2

from 2, x= 17-y

put x= 17-y in 1

15( 17-y)+8y=192

255-15y+8y=192

solve for y

-7y=192-255

-7y=-63

x=63/7

x=9

put x= 9 in 1

9+y=17

y= 17-9

y=8.

b) 59

c) Too lazy

Step-by-step explanation:

If 30% were to be a decimal, it would be 0.3 because 30% of 1 is 0.3. We will use this to figure out how many purple skittles there are.

A) To find the amount of purple skittles we must multiply the total number of skittles by the percent (in this case 0.3). Equation = (84*0.3=25.2) You can't really have 0.2 of a skittle so we would round down to the whole number (25).

B) Knowing the number of purple skittles, finding the number of non-purple skittles is straightforward. All you have to do is subtract the # of purple skittles from the total amount of skittles (84-25=59).

Answer:   [tex]\frac{14y}{25x^2}[/tex]

====================================================

Work Shown:

First calculate [tex]\frac{dy}{dx}[/tex] through the use of implicit differentiation.

Don't forget about the chain rule.

[tex]y^5 = x^7\\\\\frac{d}{dx}\left[y^5\right] = \frac{d}{dx}\left[x^7\right]\\\\5y^4\frac{dy}{dx} = 7x^6\\\\\frac{dy}{dx} = \frac{7x^6}{5y^4}\\\\[/tex]

Go back to line 3, shown above, and apply the derivative to both sides.

You'll be using the product rule.

[tex]5y^4\frac{dy}{dx} = 7x^6\\\\\frac{d}{dx}\left[5y^4\frac{dy}{dx}\right] = \frac{d}{dx}\left[7x^6\right]\\\\\frac{d}{dx}\left[5y^4\right]*\frac{dy}{dx}+5y^4*\frac{d}{dx}\left[\frac{dy}{dx}\right] = 42x^5\\\\20y^3*\frac{dy}{dx}*\frac{dy}{dx}+5y^4*\frac{d^2y}{dx^2}=42x^5\\\\20y^3*\left(\frac{dy}{dx}\right)^2+5y^4*\frac{d^2y}{dx^2} = 42x^5\\\\[/tex]

Use substitution and isolate [tex]\frac{d^2y}{dx^2}[/tex] to get the following:

[tex]20y^3*\left(\frac{dy}{dx}\right)^2+5y^4*\frac{d^2y}{dx^2} = 42x^5\\\\20y^3*\left(\frac{7x^6}{5y^4}\right)^2+5y^4*\frac{d^2y}{dx^2} = 42x^5\\\\\frac{196x^{12}}{5y^5}+5y^4*\frac{d^2y}{dx^2} = 42x^5\\\\\frac{196x^{12}}{5x^7}+5y^4\frac{d^2y}{dx^2} = 42x^5\\\\[/tex]

[tex]\frac{196x^5}{5}+5y^4*\frac{d^2y}{dx^2}=42x^5\\\\5y^4*\frac{d^2y}{dx^2}=42x^5-\frac{196x^5}{5}\\\\5y^4*\frac{d^2y}{dx^2}=\frac{210x^5-196x^5}{5}\\\\5y^4*\frac{d^2y}{dx^2}=\frac{14x^5}{5}\\\\[/tex]

[tex]\frac{d^2y}{dx^2}=\frac{14x^5}{5}*\frac{1}{5y^4}\\\\\frac{d^2y}{dx^2}=\frac{14x^5}{25y^4}\\\\\frac{d^2y}{dx^2}=\frac{14x^5*x^2}{25y^4*x^2}\\\\\frac{d^2y}{dx^2}=\frac{14x^7}{25y^4*x^2}\\\\\frac{d^2y}{dx^2}=\frac{14y^5}{25y^4*x^2}\\\\\frac{d^2y}{dx^2}=\frac{14y}{25x^2}\\\\[/tex]
