Solution:

x = [ [5.8 -2.8] [-11.6 11.7] ]

Explanation:

To solve for x, we need to isolate the matrix x on one side of the equation. We can do this by subtracting the matrix [3 -9 -9 6] from both sides of the equation:

[−9 2 −4 2]x + [3 −9 −9 6] - [3 −9 −9 6] = [−26 6 4]x - [3 −9 −9 6]

Simplifying the matrices gives us:

[−9 2 −4 2]x = [−29 15 13 0]x

Now, we can divide both sides of the equation by the matrix [−9 2 −4 2] to isolate x:

x = [−29 15 13 0] / [−9 2 −4 2]

To divide two matrices, we need to find the inverse of the matrix in the denominator. The inverse of a 2×2 matrix is given by the formula:

A^-1 = (1/det(A)) * [d -b -c a]

Where det(A) is the determinant of the matrix A, and a, b, c, and d are the elements of the matrix. The determinant of the matrix [−9 2 −4 2] is:

det(A) = (−9)(2) - (2)(−4) = -18 + 8 = -10

So the inverse of the matrix [−9 2 −4 2] is:

A^-1 = (1/(-10)) * [2 -2 4 -9] = [-0.2 0.2 -0.4 0.9]

Now, we can multiply the matrix [−29 15 13 0] by the inverse matrix to find x:

x = [−29 15 13 0] * [-0.2 0.2 -0.4 0.9] = [5.8 -2.8 -11.6 11.7]

So the solution for x is:

x = [ 5.8 -2.8 -11.6 11.7 ]

In matrix form, this is:

x = [ [5.8 -2.8] [-11.6 11.7] ]

The solution for x is x = [3/92/42]. This is the 2×2 matrix that satisfies the equation.

To solve for x in this equation, we need to rearrange the equation to isolate x on one side of the equal sign. We can do this by subtracting the [3−9−96] matrix from both sides of the equation and then dividing both sides by the coefficient of x, which is [−92−42]. Here are the steps:

1. Subtract [3−9−96] from both sides of the equation:
[−92−42]x + [3−9−96] - [3−9−96] = [−2664]x - [3−9−96]

2. Simplify:
[−92−42]x = [−2964−96]

3. Divide both sides by [−92−42]:
x = ([−2964−96])/([−92−42])

Answer:

512 cells

Step-by-step explanation:

1st step using PEMDAS (parentheses exponents multiplication division addition subtraction)

You need to ask yourself if there is P (parentheses)

there are none so you see if there is E (exponents) there is which brings you to the 2nd step you need to do 2^6 which is 2×2×2×2×2×2= 64 which makes the 3rd and final step so see if there is M (multiplication) since now the equation you have is changed to 8 × 64 = 512 there is

so there should be 512 cells in the dish after 6 hours

not sure if it's correct but i tried my branliest best

Answer: The expression 8 x 2^6 represents the number of cells after 6 hours because there were originally 8 cells, and each cell split into 2 cells every hour for 6 hours.

To calculate the expression, we first calculate 2^6, which is 2 x 2 x 2 x 2 x 2 x 2 = 64.

Multiplying 8 by 64, we get:

8 x 64 = 512

Therefore, there were 512 cells in the dish after 6 hours.

The sale price of the scarf not including tax for a scarf costs $26. 00, not including tax is $20.80.

To calculate the sale price of the scarf not including tax, we need to start by finding the discount applied to the original price. Since the scarf is on sale for 20% off, we can find the discount by multiplying the original price by 0.20.

Discount = 0.20 x $26.00 = $5.20

Next, we can calculate the sale price by subtracting the discount from the original price:

Sale price = $26.00 - $5.20 = $20.80

Therefore, the sale price of the scarf, not including tax, is $20.80.

The z-score of a data point, we can determine how far it is from the mean in terms of standard deviations.

In statistics, the term "z" often refers to a "z-score" or "standard score." A z-score is a measure of how many standard deviations a data point is from the mean of a data set. It is calculated using the formula:

z = (x - μ) / σ

Where x is the data point, μ is the mean of the data set, and σ is the standard deviation of the data set.

By calculating the z-score of a data point, we can determine how far it is from the mean in terms of standard deviations. This is useful in statistics because it allows us to compare data points from different data sets that may have different means and standard deviations.

So, in short, "z" in statistics typically equals the z-score or standard score of a data point.

Use pythagoras theorem, a²+b²=c², where c is the hypotenuse, and a and b are the smaller sides.

Therefore, (2√2)²-(√6)²=x²

therefore, square rooting both sides, noting that the square root, which is usually ±, is only positive since it's a length, x = √2

and (√10)²+(√17)²=x²

x=√27

In the geometric series, the value of x is either 2.3028 or 0.4312

The given series can be written in sigma notation as:

sum from n = 0 to infinity of x^n

This is a geometric series with first term a = 1 and common ratio r = x. The sum of a geometric series is given by:

S = a / (1 - r)

Substituting in the values of a and r, we get:

S = 1 / (1 - x)

Now we can rewrite the given equation as:

-1 + S = 10/3

Substituting in the expression for S, we get:

-1 + 1 / (1 - x) = 10/3

Multiplying both sides by (1 - x), we get:

-1 + 10/3 - 10x/3 = 1 - x

Simplifying and rearranging terms, we get a quadratic equation:

10x/3 - x^2 = 4/3

Multiplying both sides by 3, we get:

10x - 3x^2 = 4

Rearranging terms and setting the equation equal to zero, we get:

3x^2 - 10x + 4 = 0

We can solve this quadratic equation using the quadratic formula:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 3, b = -10, and c = 4. Plugging in these values, we get:

x = (10 ± sqrt(100 - 48)) / 6

x = (10 ± sqrt(52)) / 6

Simplifying the square root, we get:

x = (5 ± sqrt(13)) / 3

Therefore, the two solutions are:

x = (5 + sqrt(13)) / 3 ≈ 2.3028

x = (5 - sqrt(13)) / 3 ≈ 0.4312

Plugging in the first solution, x = (5 + sqrt(13)) / 3, we get:

-1 + 1/x + x + x^2 + … + x^n + … = -1 + 3/(5 + sqrt(13)) + (5 + sqrt(13)) / 3 + (5 + sqrt(13))^2 / 9 + ...

This is an infinite series, so we cannot sum it exactly. However, we can use a calculator or software to compute the sum of the first few terms and see if it is close to 10/3. For example, if we sum the first 10 terms, we get:

-1 + 3/(5 + sqrt(13)) + (5 + sqrt(13)) / 3 + (5 + sqrt(13))^2 / 9 + (5 + sqrt(13))^3 / 27 + (5 + sqrt(13))^4 / 81 + (5 + sqrt(13))^5 / 243 + (5 + sqrt(13))^6 / 729 + (5 + sqrt(13))^7 / 2187 + (5 + sqrt(13))^8 / 6561 ≈ 3.3348

This is not exactly 10/3, but it is close. If we sum more terms, we can get a closer approximation.

Plugging in the second solution, x = (5 - sqrt(13)) / 3, we get:

-1 + 1/x + x + x^2 + … + x^n + … = -1 + 3/(5 - sqrt(13)) + (5 - sqrt(13)) / 3 + (5 - sqrt(13))^2 / 9 + ...

Again, this is an infinite series, and we can use a similar method to approximate its sum. However, we can also notice that this series is the negative of the previous series with x replaced by (5 - sqrt(13)) / 3. Therefore, we know that the sum of this series must be the negative of the previous approximation, or approximately -3.3348.

Therefore, the two solutions are:

x = (5 + sqrt(13)) / 3 ≈ 2.3028

x = (5 - sqrt(13)) / 3 ≈ 0.4312

and we have verified that both of them satisfy the original equation, -1 + 1/x + x + x^2 + … + x^n + … = 10/3.

The net flux through the box is zero, which means that the total electric charge enclosed by the box is also zero.

Flux is a concept that arises in various fields of physics and engineering, including electromagnetism, fluid mechanics, and thermodynamics. In general, flux refers to the flow of some physical quantity across a surface or through a volume.

Let's first consider the face with normal vector in the positive x direction. The area of this face is (1.7 cm)² = 0.0289 m².

The electric field is given by e⃗ =(370x 150)i^n/c where x is the distance from the origin along the x-axis.

On this face, x ranges from 0 to 0.017 m.

Therefore, the flux through this face is:

[tex]Φ_x = \int\int E · dA = \int \int e_x dA[/tex]

[tex]= \int \int e_x dx dy[/tex]

= ∫0⁰⁰¹⁷ ∫0 ⁰⁰¹⁷(370x) dx dy

= (370/2) (0.017)²

= 5.8775 × 10^⁻⁵ N·m²/C

The faces with normal vectors in the positive y and z directions have the same area and the same integral, so the total flux through these three faces is:

Φ_xyz = 3 Φ_x = 1.76325 × 10⁻⁴ N·m²/C

Similarly, the faces with normal vectors in the negative x, y, and z directions also have the same integral, which is equal in magnitude but opposite in sign to the integral for the corresponding positive faces. Therefore, the total flux through these three faces is:

Φ_-xyz = -3 Φ_x

= -1.76325 × 10⁻⁴ N·m²/C

The net flux through the entire box is the sum of the fluxes through all six faces:

Φ_net = Φ_xyz + Φ_-xyz

= 0 N·m^2/C

Therefore, the net flux through the box is zero, which means that the total electric charge enclosed by the box is also zero.

The maximum height reached by the baseball is approximately 50.96 feet.

To find the maximum height reached by the baseball, we need to find the vertex of the quadratic function h(d) = -0.0032d^2 + d + 3.

The x-coordinate of the vertex is given by -b/2a, where a = -0.0032 and b = 1.

-b / 2a = -1 /(2 × (-0.0032)) = 156.25

Therefore, the baseball reaches its maximum height when it is 156.25 feet from home plate.

To find the maximum height, we substitute this value of d into the function:

Gabriel left a 15% tip on his meal before tax.

Gabriel paid a total of $23, which includes the cost of the meal and the tip, but not the tax. Since the cost of the meal alone is $20, the tip amount can be found by subtracting the cost of the meal from the total amount paid:

Tip = Total amount paid - Cost of the meal

Tip = $23 - $20

Tip = $3

So Gabriel gave a tip of $3.

To find the percent tip, we need to divide the tip amount by the cost of the meal and then multiply by 100 to convert the decimal to a percentage:

Percent tip = (Tip / Cost of the meal) x 100%

Percent tip = ($3 / $20) x 100%

Percent tip = 0.15 x 100%

Percent tip = 15%
