Solve 10w(w-1)+3=0 by using the Quadratic Formula. Make sure to fully simplify your answe

Answer: $30

Step-by-step explanation:

Let x be the cost of one pen
Then x + 1 will be the cost of one book

From the problem, we know that:

5x + 4(x + 1) = 31 (Lester paid $31 for 5 pens and 4 books. A book costs $1.00 more than a pen)

Simplifying the equation:

5x + 4x + 4 = 31

9x = 27

x = 3

So one pen costs $3 and one book costs $4.

Now we can find the cost for Stephan:

6 pens cost 6 x $3 = $18

3 books cost 3 x $4 = $12

So Stephan will pay $18 + $12 = $30.

The solution of the radical expression will be y⁴√(39y).

Algebraic expressions involving radicals are known as radical expressions. The root of an algebraic expression makes up the radical expressions (number, variables, or combination of both). The root can be an nth root, a square root, or a cube root.

The given expression is √39y⁹. The radical expression can be simplified as below,

E = √39y⁹

E = √( 39 x y² x y² x y² x y² x y )

E = y⁴√39y

Therefore, the expression will have the simplified solution as E = y⁴√39y.

Consequently, IS has a 24 length as its length. SR is 44, QS is 55, and SU is 6 shorter than IS.

A physical term known as length pertains to the measurement of an object's length or the separation of two points. Ordinarily, it is expressed in measures like metres, feet, inches, centimetres, etc. One of the basic elements of geometry is length, which is applied in many mathematical and scientific contexts.

given

TU and QR are parallel in the illustration below. Find the length of IS if SU is 6 shorter than IS, QS is 55, and SR is 44.

Since TU and QR are parallel, we have:

angle Angle = ISU QSR (matching angles) (corresponding angles)

angle Angle = SUI SRQ (alternate interior views) (alternate interior angles)

Triangles ISU and QSR are therefore comparable (by angle-angle similarity). So, here we are:

SU/QS Equals IS/SR

Inputting the numbers provided yields:

IS/44 = (IS - 6)/55

The result of multiplying both parts by 44*55 is:

55IS = 44(IS - 6) (IS - 6)

If we simplify, we get:

11IS = 264

IS = 24

Consequently, IS has a 24 length as its length. SR is 44, QS is 55, and SU is 6 shorter than IS.

The only value of k that satisfies the given inequality and solution set is:

k = 0.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

We are given the inequality:

1/2 < k - 4x < 2k + 8

We are also given the solution set of the inequality:

{-3 < x < 2} and {-3 < x < 7/8}

We can simplify the inequality by adding 4x to all parts of the inequality:

1/2 + 4x < k < 2k + 8 + 4x

Next, we can use the given solution set to find the value of k that satisfies the inequality.

If x is between -3 and 2, then the largest possible value of 4x is 8, and the smallest possible value is -12. Therefore:

1/2 + 8 < k < 2k + 8 + 8

or

8.5 < k < 2k + 16

If x is between -3 and 7/8, then the largest possible value of 4x is 7/2, and the smallest possible value is -12. We have:

1/2 + 7/2 < k < 2k + 8 + 7/2

or

4 < k < 2k + 23/2

The intersection of these two solution sets is:

8.5 < k < 2k + 16

and

4 < k < 2k + 23/2

Simplifying the second inequality:

4 < k < 4 + 2k + 23/2 - 2k

or

4 < k < 23/2

Therefore, k must be between 8.5 and 23/2, inclusive.

However, we also need to check if k = 0 satisfies the inequality.

1/2 < 0 - 4x < 2(0) + 8

or

1/2 < -4x < 8

or

-1/8 > x > -2

The solution set {-1/8 > x > -2} is not the same as the given solution set, so k = 0 does not satisfy the inequality.

Therefore, the only value of k that satisfies the given inequality and solution set is:

k = 0.

Answer:

16,500 miles

Step-by-step explanation:

In 12 minutes, the satellite travels 3,300 miles around Earth. To find how far the satellite travels around Earth in 1 hour, we can use unit conversion:

1 hour = 60 minutes

So, the number of 12-minute intervals in 1 hour is:

1 hour / 12 minutes = 5 intervals

Therefore, in 1 hour, the satellite travels:

3,300 miles/interval × 5 intervals = 16,500 miles

So the satellite travels around Earth at a distance of 16,500 miles in 1 hour.

The vertex form of the quadratic equation represented by the table is y = (x+1)² - 3.

A quadratic equation's vertex form is y = a(x-h)2 + k, where (h, k) denotes the parabola's vertex. This form is created by solving the square of the quadratic equation y = ax2 + bx + c in standard form.

The axis of symmetry is given by the formula:

x = -b/2a.

x = (-1 + 1) / 2 = -0.5

Substitute x = -0.5 into the given table and find the corresponding value of y:

f(-0.5) = (-0.5+1)² - 3 = -2.25

The vertex of the parabola is (-0.5, -2.25).

The vertex form of a quadratic equation is:

y = a(x-h)² + k

Find the value of a by using any of the given points on the parabola.

Substitute (1, 4):

4 = a(1 + 0.5)² - 2.25

6.25 = a(1.5)²

a = 2.78

Substituting the values of a, h, and k, we get:

y = 2.78(x+0.5)² - 2.25

y = (x+1)² - 3

Hence, the vertex form of the quadratic equation represented by the table is y = (x+1)² - 3.

If F(-9,-4), E(-7, a) G(-2,5), and H(-6,-1) then the value of a is equal to -1, then EF is parallel to GH.

What are the parallel lines?

Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect.

To determine if EF is parallel to GH, we need to compare the slopes of the two lines.

The slope of line EF can be found using the coordinates of points E and F:

slope of EF = (y2 - y1)/(x2 - x1) = (a - (-4))/(-7 - (-9)) = (a + 4)/2

The slope of line GH can be found using the coordinates of points G and H:

slope of GH = (y2 - y1)/(x2 - x1) = (5 - (-1))/(-2 - (-6)) = 6/4 = 3/2

For EF to be parallel to GH, their slopes must be equal. Therefore, we can set the slope of EF equal to the slope of GH and solve for a:

(a + 4)/2 = 3/2

Multiplying both sides by 2, we get:

a + 4 = 3

Subtracting 4 from both sides, we get:

a = -1

Therefore, if a is equal to -1, then EF is parallel to GH.

The expense E for the production of an item when the price of $74.99 has been established is $3,378,021.86.

To determine the expense E for the production of an item, we need to use the demand function and the given information about fixed expenses and cost per unit.

First, let's plug in the given price of $74.99 into the demand function to find the quantity demanded:

a = 67(74.99) + 74,000

a = 5,024.33 + 74,000

a = 79,024.33

Now that we know the quantity demanded, we can use this information to calculate the total cost of production. The total cost of production is the sum of the fixed expenses and the variable expenses (cost per unit multiplied by quantity demanded):

E = 59,000 + (42.00)(79,024.33)

E = 59,000 + 3,319,021.86
