The projection of vector a onto vector b is 2/3 i + 2/3 j + 2/3 k.

None of the given options in the choices match the correct projection.

To find the projection of vector a onto vector b, we can use the formula:

Projection of a onto b = (a · b) / |b|² * b

where (a · b) represents the dot product of vectors a and b, and |b|² is the squared magnitude of vector b.

Given:

a = i - j + 2k

b = i + j + k

First, let's calculate the dot product of a and b:

a · b = (i - j + 2k) · (i + j + k)

      = i · i + i · j + i · k - j · i - j · j - j · k + 2k · i + 2k · j + 2k · k

      = 1 + 0 + 0 - 0 - 1 - 0 + 0 + 2 + 4

      = 6

Next, let's calculate the squared magnitude of vector b:

|b|² = (i + j + k) · (i + j + k)

     = i · i + i · j + i · k + j · i + j · j + j · k + k · i + k · j + k · k

     = 1 + 0 + 0 + 0 + 1 + 0 + 0 + 0 + 1

     = 3

Now, let's substitute these values into the formula for the projection:

Projection of a onto b = (a · b) / |b|² * b

                      = (6 / 3) * (i + j + k)

                      = 2 * (i + j + k)

                      = 2i + 2j + 2k

                      = 2/3 i + 2/3 j + 2/3 k

Therefore, the projection of vector a onto vector b is 2/3 i + 2/3 j + 2/3 k.

None of the given options in the choices match the correct projection.

When the line to be examined's slope is known, and the provided point also serves as the y intercept, the slope intercept formula, y = mx + b, is utilised (0, b). B stands in for the y value of the y-intercept point in the formula.

Determine the equation of the line with a slope of 2/3 and a y intercept of (0, 4).

Solution

Step 1: Replace the provided in the formula.

Provided that the slope, m, is given as 2/3 and the y intercept, (0, 4), b = 4.

y = mx + b

y = 2 3 x + 4

2 /3 x – y = - 4

(Note: You must multiply this by the LCD of 3 to fix this since the conventional form does not support fractional numbers.)

3( 2 /3x – y) = (- 4) (- 4)

3/2x – 3y = - 12

This is the line's determined equation.

Verify is the second step.

Utilizing the formula, plot two points. In this example, y1 = 2 and Y2 = -6. 2x - 3y = - 12 2x – 3y = - 12

Let y = 2 Let y = - 6

2x – 3(2) = - 12 2x – 3(-6) = - 12

2x – 6 = - 12 2x + 18 = - 12

2x = - 6 2x = - 30 \sx = - 3 x = - 15

P1 therefore equals (-3, 2) and P2 equals (-15, -6).

The required value of y for the unit circle is: 2/3

The circle is defined as the locus of a point whose distance from a fixed point is constant i.e center (h, k).

The equation of the circle is given by:

(x - h)² + (y - k)² = r²

where:

h, k is the coordinate of the center of the circle on coordinate plane.

r is the radius of the circle.

Here,

Equation of the unit circle is given as,

x² + y² = 1

Now substitute the given value in the equation,

5/9 + y² = 1

y² = 1 - 5/9

y² = 4/ 9

y = √(4/9)

y = 2/3

Thus, the required value of y for the unit circle is 2/3

The depreciation expense for the year is $260,000. This means that the correct answer is option D: $260,000.

The depreciation expense for the year can be calculated by multiplying the depreciation per unit by the number of units produced. In this case, the depreciation per unit is given as $1.30, and the number of units produced is 200,000.

To find the depreciation expense, we can use the following formula:

Depreciation expense = Depreciation per unit × Number of units produced

Plugging in the values, we have:

Depreciation expense = $1.30 × 200,000

Multiplying, we get:

Depreciation expense = $260,000.

Therefore, the depreciation expense for the year is $260,000. This means that the correct answer is option D: $260,000.

The solution of the non-homogeneous equation to the initial value problem is:

y = 3t + 3 + 2 cos(2t)

We are given the initial value problem:

y' - 3 = 10 - 4 sin(2t)

y(0) = 5

To solve this, we can start by finding the general solution of the homogeneous equation y' - 3 = 0:

y' - 3 = 0

y' = 3

Integrating both sides with respect to t gives:

y = 3t + C

where C is the constant of integration.

Now, to find a particular solution to the non-homogeneous equation, we can use the method of undetermined coefficients. Since the right-hand side of the equation is a sinusoidal function, we can assume a particular solution of the form:

y_p = A sin(2t) + B cos(2t)

Taking the derivative of this, we get:

y'_p = 2A cos(2t) - 2B sin(2t)

Substituting y_p and y'_p into the original equation, we get:

2A cos(2t) - 2B sin(2t) - 3 = 10 - 4 sin(2t)

Matching the coefficients of sin(2t) and cos(2t) on both sides, we get:

-2B = -4 => B = 2

2A = 0 => A = 0

So, our particular solution is:

y_p = 2 cos(2t)

Therefore, the general solution of the non-homogeneous equation is:

y = y_h + y_p = 3t + C + 2 cos(2t)

To find the value of C, we can use the initial condition y(0) = 5:

y(0) = 3(0) + C + 2 cos(2(0)) = 5

C + 2 = 5

C = 3

Thus, the solution to the initial value problem is:

y = 3t + 3 + 2 cos(2t)

Under the given conditions, with cos θ = -1/3 in Quadrant III and sin ϕ = 1/4 in Quadrant II, the expression tan(θ + ϕ) evaluates to (-√120 + 1) / (√15 + √8). This represents the tangent of the sum of the two angles.

To evaluate the expression tan(θ + ϕ) given the conditions:

First, determine the values of tan θ and tan ϕ using the given information.

Since cos θ = -1/3 and θ is in Quadrant III, we can use the Pythagorean identity to find sin θ:

sin θ = √(1 - cos^2 θ) = √(1 - (-1/3)^2) = √(1 - 1/9) = √(8/9) = √8/3

Using the ratio definition of tan θ, we have:

tan θ = sin θ / cos θ = (√8/3) / (-1/3) = -√8

Similarly, since sin ϕ = 1/4 and ϕ is in Quadrant II, we can use the Pythagorean identity to find cos ϕ:

cos ϕ = √(1 - sin^2 ϕ) = √(1 - (1/4)^2) = √(1 - 1/16) = √(15/16) = √15/4

Using the ratio definition of tan ϕ, we have:

tan ϕ = sin ϕ / cos ϕ = (1/4) / (√15/4) = 1/√15

Now, we can evaluate tan(θ + ϕ) using the sum formula for tangent:

tan(θ + ϕ) = (tan θ + tan ϕ) / (1 - tan θ * tan ϕ)

Substituting the values we obtained earlier, we have:

tan(θ + ϕ) = (-√8 + 1/√15) / (1 - (-√8 * 1/√15))

Simplifying further, we can rationalize the denominator:

tan(θ + ϕ) = (-√8 + 1/√15) / (1 + √(8/15))

Multiplying the numerator and denominator by √15, we get:

tan(θ + ϕ) = (-√8 * √15 + 1) / (√15 + √8)

Therefore, the expression tan(θ + ϕ) under the given conditions is:

tan(θ + ϕ) = (-√(8*15) + 1) / (√(15) + √(8))

= (-√120 + 1) / (√15 + √8)

Note: The final expression can be simplified further, but it is left in this form since the question does not specify to simplify it.

This entry records the collection of the note receivable from Payton Summers, replacing the accounts receivable.

The first graph is the graph of the solution set of the inequality  \(-\frac{3}{5}\) x ≥ 9

Step-by-step explanation:

If multiply or divide the two sides of the inequality by a negative number, then we must reverse the sign of the inequality

Example:

2 < 3, when we divide both sides by -1, then it will be -2 > -3

Let us solve the question

∵ \(-\frac{3}{5}\) x ≥ 9

→ To find x divide both sides by \(-\frac{3}{5}\)

∵ \(-\frac{3}{5}\) is a negative number

→ From the rule above

∴ Reverse the sign of inequality

∴ x ≤ -15

∵ We have an equal sign with the sign of inequality

∴ The vertex of the arrow should be bold

∵ The sign of inequality is smaller than

∴ The arrow must be pointed to the left ⇒ (negative direction)

∵ x ≤ -15

∴ The arrow represents it has a bold starting point at -15 and pointed

   to the left

∴ The answer is the first graph

The standard error of the sample means, using the finite population correction factor, is approximately 1.50.


To calculate the standard error of the sample means with the finite population correction factor, we use the formula:
Standard Error = Population Standard Deviation / √(Sample Size) √((Population Size – Sample Size) / (Population Size – 1))
Given that the population standard deviation is 15, the sample size is 100, and the population size is 350, we can substitute these values into the formula.
Standard Error = 15 / √100  √((350 – 100) / (350 – 1)) ≈ 1.50
Therefore, the standard error of the sample means, with the finite population correction factor, is approximately 1.50. The finite population correction factor adjusts for the finite population size, resulting in a slightly smaller standard error compared to when the correction factor is not used.
