Explanation:

Let's solve the first equation for y

4x - 2y = 6

4x-6 = 2y

2y = 4x-6

y = (4x-6)/2

y = (4x/2) - (6/2)

y = 2x - 3

After doing so, we see that 4x-2y = 6 is equivalent to y = 2x-3

Therefore, the original system of equations is effectively listing the same equation twice (one has a different form compared to the other).

Both equations in this system produce the same graph, which leads to infinitely many solutions. All solutions are on the line y = 2x-3.

You can say that all solutions are in the form (x, 2x-3) where x is any real number you want.

-------------------------------

Here's another approach using substitution

4x - 2y = 6 ... start with the first equation

4x - 2( y ) = 6

4x - 2( 2x-3 ) = 6 .... replace y with 2x-3; ie plug in y = 2x-3

4x - 2(2x) - 2(-3) = 6

4x - 4x + 6 = 6

0x + 6 = 6

0 + 6 = 6

6 = 6

We get a true statement. The last equation is always true regardless of what we plug in for x, so this is another way to see how we get to infinitely many solutions.

Side note: the system is considered dependent since one equation depends on the other. The system is also consistent since it has at least one solution.

Answer: \(1\dfrac{29}{60}\text{ minutes}\)

Step-by-step explanation:

Given: A total eclipse solar eclipse in 2003 lasted \(5\dfrac{3}{20}\) minutes

\(=\dfrac{5(20)+3}{20}=\dfrac{103}{20}\text{ minutes}\)

& a total eclipse solar eclipse in 2005 lasted \(3\dfrac{2}{3}\)minutes

\(=\dfrac{3(3)+2}{3}=\dfrac{11}{3}\text{ minutes}\)

Difference= \(\dfrac{103}{20}-\dfrac{11}{3}=\dfrac{103\times3-11\times20}{60}\)

\(=\dfrac{309-220}{60}\\\\=\dfrac{89}{60}\text{ minutes}\\\\=1\dfrac{29}{60}\text{ minutes}\)

So, 2003 solar eclipse was \(1\dfrac{29}{60}\text{ minutes}\) longer than solar eclipse in 2005.

Looking at the plot, we can see that the stems range from 60 to 89, with each stem representing a group of ten pounds. The leaves represent the remaining single digits, indicating the exact weight of each tuna. There are 4 tuna that weigh less than 90 pounds

Based on the stem-and-leaf plot of the weights of yellowfin tuna caught during a fishing contest, we can count the number of tuna that weigh less than 90 pounds.

To determine the number of tuna that weigh less than 90 pounds, we need to look at the stems that are less than 9. This includes stems 6, 7, and 8. The leaves associated with these stems show the weights of the tuna that are less than 90 pounds. We can count the number of leaves associated with these stems to determine the number of tuna that weigh less than 90 pounds.

In this case, there are 4 tuna that weigh less than 90 pounds. Two of them weigh 88 pounds and the other two weigh 87 pounds. Therefore, we can conclude that there are 4 tuna that weigh less than 90 pounds in the fishing contest based on the stem-and-leaf plot.

The value of the double integral is zero.

To evaluate the double integral, we need to convert the Cartesian coordinates to polar coordinates since the region is a circle. Let's recall the formula for changing variables in double integrals:

\($\iint_R f(x,y) dA = \iint_S f(r\cos\theta, r\sin\theta) r dr d\theta$\)

where\($R$\) is the region in the \($xy$\)-plane and\($S$\) is the region in the \(r\theta$-\)plane.

In this case, the region \($D$\) is a circle with center at the origin and radius \($4$\), so we have:

\($\iint_D (6x-2y) dA = \int_0^{2\pi} \int_0^4 (6r\cos\theta - 2r\sin\theta) r dr d\theta$\)

\($= \int_0^{2\pi} \int_0^4 (6r^2\cos\theta - 2r^2\sin\theta) dr d\theta$\)

\($= \int_0^{2\pi} \left[3r^3\cos\theta - r^3\sin\theta\right]_0^4 d\theta$\)

\($= \int_0^{2\pi} (48\cos\theta - 64\sin\theta) d\theta$\)

\($= \left[48\sin\theta + 64\cos\theta\right]_0^{2\pi}$\)

Answer: 15) 97

16) 16

17) 24

Step-by-step explanation:

15) (x-75) + (x-52)+ 293=360

x - 75 + x - 52 + 293 = 360

2x - 127 + 293 = 360

2x + 166 = 360

        2x  = 194           [Subtract 166 from both side]

          x  = 97             [Divide by 2 from both side]

16) (4x+15)+(5+6x)=180         The angle of a straight line is 180.

4x + 15 + 5 + 6x = 180

10x + 20 = 180

        10x = 160            [Subtract 20 from both side]

            x = 16               [Divide by 10 from both side]

17) (x+17)+(2x+1)= 90               These two angle combined equal to 90.

x + 17 + 2x + 1 = 90

3x + 18 = 90

x = 24                           [Divide by 3 from both side]

Answer:

Step-by-step explanation:

Let A be the area of the surface of the cube.

When the side length changes from s to 4s, the new area A' can be calculated as:

A' = 6(4s)^2 = 96s^2

The change in area is then:

ΔA = A' - A = 96s^2 - 6s^2 = 90s^2

To find the integral that quantifies the change in area, we can integrate the expression for ΔA with respect to s, from s to 4s:

∫(90s^2)ds from s to 4s

= [30s^3] from s to 4s

= 30(4s)^3 - 30s^3

= 1920s^3 - 30s^3

= 1890s^3

Therefore, the integral that quantifies the change in area of the surface of a cube when its side length quadruples from s units to 4s units is:

∫(90s^2)ds from s to 4s

= 1890s^3 from s to 4s

= 1890(4s)^3 - 1890s^3

= 477,840s^3 - 1890s^3

The prime factorization of the number 21 is:

21 = 3*7

We want to write the prime factorization of 21.

To do so, we just need to divide the number by prime numbers.

The first prime number we can try is 2, if we divide by 2 we get:

21/2 = 10.5

This is not an integer, so 2 is not a factor.

The next one is 3:

21/3 = 7

Now we can rewrite:

21 = 3*7

The distance from the origin to the complex number and can be calculated using the formula: r = √(Re^2 + Im^2)

a) To write a complex number in trigonometric form with a positive angle (≤ θ ≤), we use the formula:

z = r(cosθ + isinθ)

where r is the magnitude (or modulus) of the complex number and θ is the argument (or angle) of the complex number.

b) To write a complex number in trigonometric form with a negative angle (≤ -θ ≤), we use the formula:

z = r(cos(-θ) + isin(-θ))

where r is the magnitude (or modulus) of the complex number and -θ is the negative angle.

Please note that in both cases, r represents the distance from the origin to the complex number and can be calculated using the formula:

r = √(Re^2 + Im^2)

Two choices correctly describe reflections in the given diagram:

Triangle A is reflected across the x-axis to form triangle D.

Triangle D is reflected across y = x to form triangle B.

The first reflection in the diagram involves triangle A being reflected across the x-axis to form triangle D. When a shape is reflected across the x-axis, its y-coordinates are negated while its x-coordinates remain the same. In this case, triangle A has vertices at (1,1), (3,1), and (2,3). When it is reflected across the x-axis, the y-coordinates of its vertices are negated, giving us triangle D with vertices at (1,-1), (3,-1), and (2,-3).

The second reflection in the diagram involves triangle D being reflected across y = x to form triangle B. When a shape is reflected across y = x, its x-coordinates and y-coordinates are swapped. In this case, triangle D has vertices at (1,-1), (3,-1), and (2,-3). When it is reflected across y = x, its x-coordinates become its y-coordinates and its y-coordinates become its x-coordinates, giving us triangle B with vertices at (-1,1), (-1,3), and (-3,2).

Therefore, the correct choices that describe reflections in the given diagram are: Triangle A is reflected across the x-axis to form triangle D, and triangle D is reflected across y = x to form triangle B.

The equation for the transformed logarithm that passes through the points (3,0) and (0,2) can be written as f(x) = -b * log(base a)(x - h) + k, where a, b, h, and k are constants to be determined.

To find the equation for the transformed logarithm, we need to use the given points (3,0) and (0,2) to determine the values of a, b, h, and k. Let's start with the point (3,0). Plugging the x-coordinate (3) into the equation, we have:

0 = -b * log(base a)(3 - h) + k

Next, we'll use the point (0,2) to obtain another equation. Plugging the x-coordinate (0) into the equation, we get:

2 = -b * log(base a)(0 - h) + k

Simplifying these equations, we have a system of equations to solve for a, b, h, and k. However, since the equation involves a logarithm, we need more information to determine the specific values of a, b, h, and k.The transformed logarithm function includes transformations such as vertical stretches/compressions (b), horizontal shifts (h), and vertical shifts (k). Without more specific information about these transformations or the base of the logarithm, it is not possible to determine the equation uniquely.

In general, the equation for a transformed logarithm can be written as f(x) = -b * log(base a)(x - h) + k, where a, b, h, and k are constants determined by the specific transformations applied to the logarithm function. It's important to have additional information or instructions to determine the values of a, b, h, and k and provide an equation that accurately represents the given transformed logarithm.

For a 7 times 8 matrix A; dim Nul A = 6 and Col A does not span R^2, but at most a two-dimensional subspace of R^7.

To determine the dimension of the null space (Nul) of matrix A, we can use the rank-nullity theorem, which states that the dimension of the null space plus the dimension of the column space (Col) equals the number of columns of the matrix.

In this case, we have a 7x8 matrix A with two pivot columns.

The pivot columns are the columns in the matrix that contain leading non-zero entries in a row reduced echelon form.

Since there are two pivot columns, it means that there are two leading non-zero entries in the row reduced echelon form of matrix A.

The remaining 8 - 2 = 6 columns are free columns, which do not contain pivot elements.

The dimension of the null space, dim Nul A, is equal to the number of free columns, which in this case is 6.

Therefore, dim Nul A = 6.

Regarding the column space of matrix A, Col A, it is not R^2 because the number of pivot columns represents the maximum number of linearly independent columns in the matrix.

In this case, there are two pivot columns, so the column space of matrix A can span at most a two-dimensional subspace of R^7, not R^2.
