Step-by-step explanation: well first the product means multiplication, so u multiply 3 and j. and the second part is 8 less than that, so 8 is the last part so u do 3 times j minus 8. i graduated from high school last year so i know what im doin

According to the question,

Let,

The homogeneous equation corresponding to W = Span(2, 1, -3) is 0.

To discover a set of one or more homogeneous equations for which the corresponding answer set is W = Span(2, 1, -three), we will use the idea of linear independence.

The set of vectors v1, v2, ..., vn is linearly unbiased if the only strategy to the equation a1v1 + a2v2 + ... + anvn = 0 (wherein a1, a2, ..., an are scalars) is a1 = a2 = ... = an = 0.

Since W = Span(2, 1, -3), any vector in W may be represented as a linear aggregate of (2, 1, -three). Let's name this vector v.

Now, to find a homogeneous equation corresponding to W, we need to discover a vector u such that u • v = 0, in which • represents the dot product.

Let's bear in mind the vector u = (1, -1, 2). To check if u • v = 0, we compute the dot product:

(1)(2) + (-1)(1) + (2)(-3) = 2 - 1 - 6 = -5.

Since u • v = -five ≠ zero, the vector u = (1, -1, 2) is not orthogonal to v = (2, 1, -3).

To discover a vector that is orthogonal to v, we can take the go product of v with any other vector. Let's pick the vector u = (1, -2, 1).

Calculating the cross product u × v, we get:

(1)(-3) - (-2)(1), (-1)(-3) - (1)(2), (2)(1) - (1)(1) = -3 + 2, 3 - 2, 2 - 1 = -1, 1, 1.

So, the vector u = (-1, 1, 1) is orthogonal to v = (2, 1, -3).

Therefore, the homogeneous equation corresponding to W = Span(2, 1, -3) is:

(-1)x + y + z = 0.

Note that this equation represents an entire answer set, now not only an unmarried solution. Any scalar more than one of the vectors (-1, 1, 1) will satisfy the equation and belong to W.

Lin should expect to sell 10 more cups of lemonade on Sunday compared to Saturday, assuming the high temperature on Sunday is 5 degrees warmer than on Saturday.



To determine the number of cups of lemonade Lin should expect to sell on Sunday compared to Saturday, we need to substitute the temperatures into the equation c = 2t - 89.

Let's assume the high temperature on Saturday is represented by t, which means the high temperature on Sunday will be t + 5 (5 degrees warmer). Substituting these values into the equation:

c(Saturday) = 2t - 89

c(Sunday) = 2(t + 5) - 89

Simplifying the equation for Sunday:

c(Sunday) = 2t + 10 - 89

c(Sunday) = 2t - 79

To find the difference in the number of cups sold, we need to subtract the equation for Saturday from the equation for Sunday:

c(Sunday) - c(Saturday) = (2t - 79) - (2t - 89)

c(Sunday) - c(Saturday) = 2t - 79 - 2t + 89

c(Sunday) - c(Saturday) = 10

Therefore, Lin should expect to sell 10 more cups of lemonade on Sunday compared to Saturday, given that the high temperature on Sunday is 5 degrees warmer than on Saturday.

When a hollow plastic ball is projected into the air, there is air resistance opposing its motion. The magnitude of the ball's acceleration is not equal to zero. At time t, the ball is moving up and to the right at a 45-degree angle to the horizontal.

The acceleration of the ball can be determined by considering the forces acting on it. Since there is air resistance opposing the ball's motion, its acceleration is less than the acceleration due to gravity (g). Therefore, the statement "a < g" best represents the magnitude and direction of the ball's acceleration at time t. This means that the ball's acceleration is directed downward but is smaller than the acceleration due to gravity. The presence of air resistance affects the ball's motion and causes its acceleration to be less than the acceleration due to gravity.

he resolution of the A/D converter is 0.39% of the full-scale value.

To find the resolution in millivolts, we can use the formula:

Resolution = Vfull-scale value / (2^n)

Given that the full-scale value is 5 volts and the A/D converter is 8 bits, we have:

Resolution = 5 volts / (2^8) = 5 volts / 256 = 0.0195 volts

To convert this to millivolts, we multiply by 1000:

Resolution = 0.0195 volts * 1000 = 19.5 millivolts

Therefore, the resolution of the A/D converter is 19.5 millivolts.

To express the resolution in terms of the % of full-scale value, we can use the formula:

Resolution (%FS) = (Resolution / Vfull-scale value) * 100

Using the resolution value we obtained in part 1 (0.0195 volts) and the full-scale value of 5 volts, we have:

Resolution (%FS) = (0.0195 volts / 5 volts) * 100 = 0.39%

Therefore, the resolution of the A/D converter is 0.39% of the full-scale value.

(x + 4) ^2 = (x^2 + 8x + 16)

Step-by-step explanation:

You have to factor the equation (X + 4) ^2.

Expanded: (x + 4) * (x + 4)

Using the foil technique:

First: (x) * (x) = x^2

Outer: (x) * (4) = 4x

Inner: (4) * (x) = 4x

Last: (4) * (4) = 16

Factor equations should look like this

a^2 + bx + c, where the Outer and Inner values are added together. Resulting in:

x^2 + 8x + 16

The annual rate of population growth in the US was about 1.2% in 2015, then the growth factor will be 1.012. The growth factor depends upon annual growth rate.

Growth factor typically refers to a constant multiplier that is used to calculate the growth or decay of a quantity over time. It is given as:

Growth factor = (1 + annual growth rate)

Therefore, the growth factor for the US in 2015 can be calculated as follows:

Growth factor (1+0.012) = 1.012

Therefore, the growth factor for the population of the US in the year 2015 was about 1.012.

The inequality is true, so we can conclude that Nicole can buy at most 2 CDs.

This is a parabola's equation in vertex form, with the vertex located at (4, 12). With the help of this knowledge, we can draw the parabola's graph.

(a) We can substitute \($x=5$\) into the inequality and simplify as follows:

\($9.99(5)+11.95+10 \leq 50$\)

\($49.95+11.95 \leq 50$\)

\($61.90 \leq 50$\)

Since the inequality is not true, we can conclude that Nicole does not have enough money to buy 5 CDs.

(b) To write an inequality that represents the number of CDs Nicole can buy, we can start with:

\($9.99x+11.95+10 \leq 50$\)

Simplifying, we get:

\($9.99x \leq 27.10$\)

\($x \leq \frac{27.10}{9.99} \approx 2.71$\)

Since Nicole cannot buy a fraction of a CD, she can buy at most 2 CDs. To confirm, we can substitute $x=2$ and check if the inequality is true:

\(9.99(2)+11.95+10 \leq 50\\31.93 \leq 50\)

The octagon's remaining equal angles are each 121.5 degrees.

The sum of the interior angles of any polygon is given by the formula:

Sum of interior angles = (n - 2) * 180 °

where n is the number of sides of the polygon.

In the case of an octagon, which has 8 sides, the sum of the interior angles is:

Sum of interior angles = (8 - 2) * 180°

= 6 * 180°

= 1080°

Now, we subtract the known angles from the sum:

1080 ° - (120 ° + 110° + 130 ° + 144° + 90°) = 486°

We are left with 486 °, which is the sum of the equal angles in the octagon. Since there are four equal angles remaining, we divide 486 ° by 4:

The size of each of the equal angles is 162 degrees. All the remaining three angles are equal to each other and have a value of 162 degrees.

We know that the sum of all interior angles in a polygon = (n-2)180

where n is the number of sides of that polygon.

In this case, we have an octagon,

The sum of all interior angles in an octagon = (8-2) 180

n = 8 ( an octagon has 8 sides)

The sum of all interior angles in an octagon, A = 1080 degrees.

Sum of given angles = 120 + 110 +130 +144 + 90 = 594

We have 3 more angles in the octagon which are all equal, let's say x

A + x + x + x = 1080

The value of Vou = 14, ||V|| = √(106) and ||U|| = √(3).

The cosine of the angle between U and V is (14) / (√(106)√(3)).

To find the following for the vectors V = 9i - 5k and U = i + j + k:

A. Vou and Vol:

Vou is the dot product of vectors V and U, which is given by:

Vou = V · U = (9i - 5k) · (i + j + k)

= (9i - 5k) · i + (9i - 5k) · j + (9i - 5k) · k

= 9i · i - 5k · i + 9i · j - 5k · j + 9i · k - 5k · k

= 9 - 5(0) + 0 - 5(0) + 0 - 5(-1)

= 9 + 0 + 0 + 0 + 0 + 5

= 14

Now, Vol is the dot product of vectors V and U, which is given by:

Vol = V · U = ||V|| ||U|| cos(θ)

Where ||V|| represents the magnitude of vector V, ||U|| represents the magnitude of vector U, and θ is the angle between the two vectors.

B. The cosine of the angle between U and V:

To find the cosine of the angle between U and V, we can use the dot product formula:

cos(θ) = (V · U) / (||V|| ||U||)

||V|| = √((9²) + 0 + (-5²)) = √(81 + 25) = √(106)

||U|| = √((1²) + (1²) + (1²)) = √(3)

Substituting the values into the formula:

cos(θ) = (14) / (√(106) √(3))

Therefore, the cosine of the angle between U and V is (14) / (√(106)√(3)).
