The missing values in the ratios are 2/3 and 16/3 in the set of 1, _ , _.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given are two sets of ratios 2, _, _ and 3, 1, 8.

If we observe the first value of the first and second ratio we see that

The second set of ratios is (3/2) or 1.5 times larger than the first set of ratios.

So the second and the third value of the first set of ratios are (1/3/2) = 2/3 and 8/(3/2) = 16/3.

The polynomial graph has only one relative maximum at point b.

A function's graph can be used to determine the relative peaks and minima of the function. A relative maximum or minimum is a point that is higher than the points directly adjacent to it on both sides. The opposite is true for a relative maximum or minimum. When drawing a curve, relative maxima and minima are crucial spots that can be discovered using either the first or second derivative test.

Given, a polynomial function by observing the graph itself we conclude that the graph has no absolute maxima as it is going towards negative and positive infinity but it has a relative maximum a point b.

1. Triangle ABC with the vertices, A(0, 2), B(6, 4), and C(4, -2) is drawn and attached below.

2. The midsegment is EF. This is verified using the triangle midsegment theorem which states that EF = 1/2(AC).

The midsegment of a triangle is the line segment that joins the midpoints of two sides of a triangle together. Every triangle typically has three midsegments.

According to the triangle midsegment theorem, the length of the midsegment is half the length of the third side of the triangle that it is parallel to.

The midpoint of a line is its middle, which can be calculate using the formula:

M(x, y) = [tex](\frac{x_2 - x_1}{2}, \frac{y_2 - y_1}{2})[/tex].

1. The coordinate of the three vertices that is used to draw a triangle are:

A(0, 2), B(6, 4), and C(4, -2).

The triangle is in the attachment below.

2. To plot the midsegment of the triangle, determine the midpoints of AB and BC, then plot the coordinate where both midpoints would be joined.

Midpoint of AB = (x, y) = (0+6)/2, (2+4)/2

= (6/2, 6/2)

= (3, 3) (let this be point E)

Midpoint of AB = (x, y) = (4+6)/2, (−2+4)/2

F = (5, 1)

The midsegment will have the endpoints, E(3, 3) and F(5, 1).

To verify the segment draw is the midsegment according to the triangle midsegment theorem, find the length of the midsegment, EF, and the length of the third side, AC using the distance formula, d = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].

EF = √[(5−3)² + (1−3)²]

EF = √8 units

AC = √[(4−0)² + (−2−2)²]

AC = √32 units

Based on the triangle midsegment theorem:

EF = 1/2(AC)

Plug in the values:

√8 = 1/2(√32)

√8 = 1/2(4√2)

√8 = 2√2

2√2 = 2√2 (true)

This means that EF is a midsegment of triangle ABC.

Utilizing some of the inventory procedures, the aforementioned inventory table is finished.

The First-in, First-out (FIFO) principle presupposes that the physical flow of products sold corresponds to the order in which they were acquired.

The Last-in, First-out method (LIFO) bases the cost of products sold on the most recent inventory acquisitions.

The weighted-average technique calculates the ending inventory and cost of goods sold using the average cost of goods.

Allocating the expenses of products sold and ending inventory are not based on any presumptions in Specification Identification. It substitutes specified expenses instead.

An equation 7x+3x+10= -2[-5x +(-5)] has infinite solutions and an equation 7x+3x+10= -2[-5x + (-4)] has no solution.

Given that:

7x+3x+10 = -2 (_x + _)

=> 10x + 10 = -2 (_x + _)

Putting in the blank -5 so as to satisfy the equation that has an infinite solution.

=> 10x + 10 = -2(-5x + -5)

This is the equation that shows that it has infinite solutions and they are in the same line.

For no solutions

7x+3x+10 = -2 (_x + _)

In no solution, the value of b is not equal to -5.

For equation:

7x+3x+10 = -2 (-5x + b) [If putting value in first blank = -5]

Therefore, -2 (-5x + b) is parallel to 10x+10 for any value of b not equal to -5. Parallel lines never intersect. So solutions are no solution.

Putting the value of b = -4

7x+3x+10 = -2 [-5x + (-4)]

The area of the final polygon is 8x² + 4x - 16

From the question, we are to determine the area of the final polygon.

From the given information,

"A polygon with an area of (4x^2 + 2x - 16) square units is combined with a rectangle that has a width of (6x + 2) units and a length of (x - 5) units."

First, we will determine the area of the rectangle.

Area of the rectangle = (6x + 2)(x - 5)

Area of the rectangle = 6x² - 30x + 2x - 10

Area of the rectangle = 6x² - 28x - 10

Now, we will add it to the area of the polygon

4x² + 2x - 16 + 6x² - 28x - 10

= 4x² + 6x² - 28x + 2x - 10 - 16  

= 10x² - 26x -26

Also,

From the given information,

"a polygon with an area of (2x^2 - 30x - 10) square units is removed"

Then,

The area of the final polygon = 10x² - 26x - 26 - (2x² - 30x - 10)

Area of the final polygon = 10x² - 26x - 26 - 2x² + 30x + 10

Area of the final polygon = 10x² - 2x² + 30x - 26x + 10 - 26

Area of the final polygon = 8x² + 4x - 16

The equation of circle (x-4)² + (y+11)² = 64

What is a Circle?

All points in a plane that are at a specific distance from a specific point, the center, form a circle. Alternatively, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant.

Here we know that (h,k)=(4,-11) but we are not given the radius.

However, we can find the radius by using the distance formula.

Therefore,

r = √[(x2 - x1)² + (y2 - y1)²]

r = √[(4 - 4)² + (-3 + 11)²]

r = √[(0)² + (8)²]

r = √(8²)

r = 64

An equation of the circle with center (h,k) and radius r is

(x−h)^2 +(y−k)^2=r^2

Substitute the values in the equation of circle as follows:

(x-4)² + (y+11)² = 8²

(x-4)² + (y+11)² = 64

Therefore, the equation of the circle is (x-4)² + (y+11)² = 64

The value of dy/dx is -27/8 for 1=5x³+2y²+4xy  at (-1,3).

A differential equation is an equation that contains one or more functions with its derivatives.

Given,

The equation is 1=5x³+2y²+4xy

We need to differentiate the given equation

5.3x²+4ydy/dx+4(xdy/dx+y)=0

15x²+4ydy/dx+4(xdy/dx+y)=0

15x²+4ydy/dx+4xdy/dx+4y=0

15x²+dy/dx(4y+4x)+4y=0

dy/dx(4y+4x)=-15x²-4y

dy/dx=-15x²-4y/4y+4x

Now plug in x =-1 and y=3

dy/dx=-15(-1)²-4(3)/4(3)+4(-1)

=-15-12/12-4

According to the give triangle ABC, the length of the line segments

BD is 5.5

CD is 13.5

AC is 10.5

Triangle:

Triangle refers a polygon with three sides having three vertices. The angle formed inside the triangle is equal to 180 degrees.

Given,

AD is a median in ΔABC, if BD = 5x - 8, CD = 3x + 12, and AC = 7x -14.

Here we need to find the length of the all three segments.​

We know that, the length of BC is the sum of BD and CD.

Thus can be written as,

BC = BD + CD

Now, we have to apply the values on the equation, then we get,

Length of BC is x.

=> 5x - 8 + 3x + 12

=> 8x - 4

=> 8x = 4

=> x = 1/2

Now, we have to apply the value of x as 1/2, on the line segments, then we get,

BC = 5(1/2) - 8

BC = 5/2 - 8

BC = 11/2 = 5.5

So, the value of CD is,

CD = 3(1/2) + 12

CD = 3/2 + 12

CD = 27/2

CD = 13.5

Then the value of AC is,

AC = 7(1/2) - 14

AC = 7/2 - 14

AC = 21/2

AC = 10.5

Therefore, the line segments BC is 5.5, CD is 13.5 and AC is 10.5.

Player 2 average hits = 1 hit per game
Player 2 Total hits this season = 22
Player 2 total game this season = 22/1 = 22
