Answer:  The correct answer is x > −5.733333  (the second and third buttons (">" and "-5.73") shown in the screenshot)

Step-by-step explanation:

Solve the inequality:

−1.5x−3.1 < 5.5

Step 1 - Add 3.1 to both sides

−1.5x − 3.1 + 3.1 < 5.5 + 3.1

−1.5x < 8.6

Step 2 - Divide both sides by -1.5

−1.5x / -1.5 < 8.6 / -1.5

x > −5.733333

The completion of the inventory table is as follows:

A = $48

B = $264

C = $420

D = $304.

What methods are used for inventory?

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.

Given the fact the ball rolls down the slope, the gravitational force is the force caused the ball to move downhill.

In the test, when the ball is placed on the slope and slightly disturbed then ball will roll down the slope with increasing speed. This increasing speed of ball is due to the component of weight of ball which is along the inclined plane.

As shown in the attached, the component of weight perpendicular to inclined plane is used to counterbalance the normal force while other component of weight parallel to the inclined plane is accelerating the ball down the plane. Therefore, the Option D is correct.

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

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.

As per the given condition of the forty percent students from the science program are 8th grader out of total 50 students present in the class , then number of students which are not 8th grader are 30 students.

As given in the question,

Total number of students present in the class of science program = 50

Percent of students present in the class of science program are of 8th graders = 40 percent

Let y be the number of student not present in the class of science program

( 100 - 40 )% of 50 = y  

⇒ 60 % of 50 = y

⇒ (60/100) × 50 = y

⇒ y = ( 60 × 50) / 100

⇒ y= 3000/100

⇒ y = 30 students

Therefore, for the given condition of the forty percent students from the science program are 8th grader out of total 50 students present in the class ,then number of students which are not 8th grader are 30 students.

  (6)  The functions f and g are not inverses

Step-by-step explanation:

You want to know which of several statements proves f(x) = (9x+9)/7 and g(x)=(7x+9)/9 are inverses of each other.

The inverse of f(x) can be found by solving ...

  x = f(y)

  x = (9y +9)/7

  7x = 9y +9

  7x -9 = 9y

  y = (7x -9)/9

The plus sign in f(x) turns into a minus sign in its inverse function. g(x) is not the inverse of f(x).

The functions f and g are not inverses.

__

Additional comment

As answer choice (2) suggests, graphs of inverse functions will be reflections of each other in the line y=x. The attached graph shows they are not, hence f(x) is not the inverse of g(x).

The correct statement that correctly verifies the two functions f(x) = (9x + 9) / 7 and g(x) = (7x + 9) / 9 is the functions f and g are not inverses

The inverse of a function is solved by making the input function equal to the output function

the inverse of f(x) = (9x + 9) / 7

f(x) = y = (9x + 9) / 7

7y = 9x + 9

9x = 7y - 9

x = (7y - 9) / 9

changing the input and output of the new functions

hence f⁻¹ =  (7x - 9) / 9

Since f⁻¹ ≠ g(x) the last option is the correct option

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.

They needed 4 more games to have same number of hits which is 26 hits

The answer to the common factor is?

Factors that are shared by two or more numbers are referred to as common factors in mathematics. To put it another way, a common factor is a number that will divide a group of two or more numbers exactly.

Given That:
Player 1 average hits = 2 hit per game
Player 1 Total hits this season = 18
Player 1 total game this season = 18/2 = 9

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

If we add 4 game for each player than

Player 1 total hits = 18 + 4(2) = 26

Player 2 total hits = 22 + 4 = 26

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

=-27/8

The maximum height of the baseball will be 19.64 m

What are Equations of Motion?

The three equations of motions are :

Velocity-Time relation

v = u + at

Position-Time relation

S = ut + ( 1/2 ) at²

Position-Velocity relation.

v² - u² = 2aS

where v = final velocity

u = initial velocity

t = time

S = displacement

a = acceleration

Given data ,

Initial velocity u = 19.62 m/s

t = 2.01 s

a = -9.8 m/s² ( acceleration due to gravity )

To find maximum height of the baseball S , first we calculate the final velocity v

When the ball reaches the maximum height , the final velocity v will be 0

So v = 0

And , from the third equation of motion , we can find the maximum height of the baseball as

Position-Velocity relation.

v² - u² = 2aS

Substituting the value of v , u and a in the above equation , we get

0 - ( 19.62 )² = 2 x ( -9.8 ) x S

- 384.9444 = -19.6 x S

Dividing by ( -19.6 ) on both sides , we get

S = 19.64 m

Hence , the maximum height of the baseball will be 19.64 m
