The vertex of the function g(x)=-2x²- 14x +12 is (-7/2, 25/2).

A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .

The given function is g(x)=-2x²- 14x +12

We need to find the vertex of the function.

y=-2x²- 14x +12

To make it a perfect square we are adding and subtracting (7/2)²

y=-2x²- 14x +(7/2)²+12-49/4

y=-2(x+7/2)²+25/2

x+7/2=0

Subtract 7/2 on both sides

x=-7/2

and y=25/2

Hence, the vertex of the function g(x)=-2x²- 14x +12 is (-7/2, 25/2).

Answer:

Answer:A=20000(1+0.059)^10A=$35,480.49

Step-by-step explanation:

The volume of the resulting solid is 16623 when a circular hole of radius 5 has been bored through the center of a ball with a radius of 16.

Given that,

A circular hole of radius 5 has been bored through the center of a ball with a radius of 16.

We have to determine the resulting solid's volume.

We know that,

Volume of the original ball= 4/3πr³

Radius r=16

Volume v₁=4/3π(16)³ = 16384π/3

Volume of hole = 4/3πr³

Radius r=5

Volume v₂=4/3π(5)³ = 500π/3

Volume of the resulting solid = v₁-v₂

= 16384π/3 - 500π/3

= 15882π/3

= 16623

Therefore, The volume of the resulting solid is 16623 when a circular hole of radius 5 has been bored through the center of a ball with a radius of 16.

Slope is a measure of how much a line changes in the y-direction for every unit of change in the x-direction. It is typically represented by the m in the equation y = mx + b. Line through points -5, -10, and -1 has a slope of 5.

Slope is calculated by taking the difference in the y-coordinates divided by the difference in the x-coordinates of two points on a line. Since we only have one point, we cannot calculate the slope .The slope of a line is equal to the change in y divided by the change in x. We can calculate the slope by subtracting the y-coordinates and then dividing by the difference of the x-coordinates. In this case, the change in y is (10 - (-5)) = 15 and the change in x is (5 - (-1)) = 6. Therefore, the slope of the line is 15/6 = 5.

The amount of money lost per year is 15x

Where 100x can be any amount

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Let the total amount of money earned in a year from the field = 100x

The new field area.

= 100% - 15%

= 85%

Now,

The amount of money earned in a year from the new field area.

The slope intercept form of equation of required line is y = 3x + 9

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If  [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m =  [tex]tan\theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

Here,

Slope = 3

The line passes through (8, 33)

The function is continuous when it has these two features:

For the definitions in this problem, we have that:

For the first two functions, the function can be simplified as follows:

(x² - 16)/(x + 4) = [(x - 4)(x + 4)]/(x + 4) = x - 4.

Hence the limit at x = -4 is given as follows:

To solve the equation y = -5/2x - 7, we can first multiply both sides of the equation by 2x + 7, which is the denominator of the fraction on the right-hand side. This gives us the equation 2xy + 7y = -5, which we can rearrange to isolate the variable y on one side of the equation. Dividing both sides of the equation by 2x + 7, we get y = -5 / (2x + 7). This is the solution to the original equation.

Option B is correct, the perimeter of the entire design is 64cm.

In the design, there are two congruent trapezoids stitched together.

So, the given length = 14cm & base = 9cm

There are 4 bases and 2 lengths.

So, the perimeter of a trapezoid is

= length + base

= 14 x 2 + 9 x 4

= 64 cm.

So, the perimeter of the entire design is 64 cm.

The perimeter of a trapezoid is the sum of the lengths of every facet of the trapezoid. A trapezoid is a quadrilateral that has aspects parallel to each different and non-parallel aspects termed bases and legs respectively. The perimeter of a trapezoid is defined as the overall length of the boundary of the trapezoid. A trapezoid is a -dimensional shape (2nd shape) and an irregular polygon. thus, the perimeter of the trapezoid is calculated by including the period of all its aspects.

The perimeter of a trapezoid is expressed in linear units like, 'inches', 'feet', 'meters' or 'centimeters', and many others. The formulation of the perimeter of a trapezoid is a simple one wherein the duration of all 4 sides is added. study the trapezoid ABCD given below wherein aspects AB and CD (bases) are parallel to each other while ad and BC (legs) are non-parallel sides.

The length of the rectangle is 6m - 2.

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

Area = 30m² - 20m - 10

Width = 5m - 5

Now,

Area = Length x Width

30m² - 20m - 10 = Length x (5m - 5)

10(3m² - 2m - 1) = Length x (5m - 5)

10(3m² - (3 - 1)m - 1 = Length x (5m - 5)

10 (3m² - 3m + m - 1) = Length x (5m - 5)

10 (3m(m - 1) + 1(m - 1)) = Length x (5m - 5)

10 (3m + 1)(m - 1) = Length x 5(m - 1)

(m - 1) gets canceled.

10(3m - 1) = Length x 5

2(3m - 1) = Length

Length = 6m - 2

The Poster Dimensions of rectangle will be:

W = 18 inches

Y = 36 inches

Area can be defined as the amount of space covered by a plane of a particular shape. It is measured in "number" of square units (square centimeters, square inches, square feet, etc.). The area of ​​a rectangle is the number of unit squares that fit in the rectangle. Examples of rectangles are flat surfaces such as laptop monitors, chalkboards, and painting canvases. You can use the rectangle area formula to find the space occupied by these objects.

Now,

Let's say the printable area of ​​a rectangular poster is 512 square inches

"x". " and "y" - the dimensions of the printed area of ​​the poster

A(p) = printed area of ​​the poster = x × y

512 = x × y ⇒ y = 512/x

Therefore, The total area of ​​the poster is:

A( t) = ( y + 4 ) ×  ( x + 2 )

⇒ A(t) = yx +2y +4x + 8 and y = 512/x

Total Area of x or Total poster area as x function:

   A(x) =( 512/x)*x + 2* (512/x) + 4*x + 8

   A(x) = 512 + 1024/x + 4 *x + 8

⇒ A(x) = 520 + 1024/x + 4*x

Differentiating both sides of the equation gives:

     A´(x) = - 1024/x² + 4

     A´(x) = 0

⇒ - 1024 /x² = -4

⇒  4*x² = 1024

⇒ x² = 1024/4

⇒ x² = 256

or, x = 16 inches

and y = 512/x

⇒ y = 512/16

⇒ y = 32 inches

So x is found, the y dimension of the print area, Than n is the dimension of the poster:

Therefore,

w = x + 2 ⇒ w = 16 + 2 w = 18 in

And,

Y = y + 4 ⇒ Y = 32 + 4 Y = 36 in

The required pounds of Bolivian coffee and Colombian coffee are 2500 and 1500 respectively.

A equation is supposed to be linear equation in two factors in the event that it is written as ax + by + c=0, where a, b and c are genuine numbers and the coefficients of x and y, i.e an and b separately, are not equivalent to nothing. For instance, 10x+4y = 3 and - x+5y = 2 are direct conditions in two factors.

Let x be the pound of Bolivian coffee and y is that of Colombian coffee.

Bolivian coffee sells for $4.59 per pound, and Colombian coffee sells for $5.95 per pound and whole mixture sells for $5.10.

So,  4.59x + 5.95y = 5.10(4000)

4.59x + 5.95y = 20400--------------------(1)

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.

The fair die is thrown twice.

The total number of outcomes if a fair die is tossed twice is 36.

The favorable number of outcomes, which also contains six, is six.

Following is a calculation of the likelihood of the same number appearing twice.

Probability = (Number of possible outcomes)/(Total number of outcomes)
