Answer:

The image connected shows what the graph looks like.

Step-by-step explanation:

If there is a line underneath the inequality (≥, ≤), then the line WILL filled in.

If there isn't a line underneath the inequality (>, <), then the like WONT be filled in

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

Make sure the variable is before the number.

(THINK: Say the inequality out-loud, x is greater than 6 so the fraction will go to the RIGHT and WONT be filled in.)

The pairwise comparisons that need to be made for this anova result will be b.3

In order to determine the number of pairwise comparisons needed for a one-way between-subjects ANOVA with three groups, we can use the formula:

N = (k * (k-1)) / 2

Where N represents the number of pairwise comparisons and k represents the number of groups. In this case, k = 3.

Plugging in the values:

N = (3 * (3-1)) / 2

N = (3 * 2) / 2

N = 6 / 2

N = 3

The RTS of the isoquant is 1000K, indicating the rate at which labor can be substituted for capital while maintaining constant production. The labor to capital cost ratio is 0.5. To minimize the cost of producing q units per hour, the specific value of q is needed to find the optimal combination of K and L along the expansion path, represented by the cost function C(K, L) = 40K + 20L.

The RTS (Rate of Technical Substitution) measures the rate at which one input can be substituted for another while keeping the production level constant. To determine the RTS, we need to calculate the derivative of the production function with respect to L, holding q constant.

Given the production function q = 1000KL, we can differentiate it with respect to L:

d(q)/d(L) = 1000K

Therefore, the RTS of the isoquant for production level q is 1000K.

The ratio of labor to capital cost can be calculated by dividing the labor cost by the capital cost.

Labor cost = $20/hour

Capital cost = $40/machine/hour

Ratio of labor to capital cost = Labor cost / Capital cost

                              = $20/hour / $40/machine/hour

                              = 0.5

The ratio of labor to capital cost is 0.5.

To find the combination of K and L that minimizes the cost of producing q units per hour, we need to set up the cost function and take its derivative with respect to both K and L.

Let C(K, L) be the total cost function.

The cost of capital is $40 per machine per hour, and the cost of labor is $20 per hour. Therefore, the total cost function can be expressed as:

C(K, L) = 40K + 20L

To produce q units per hour at minimal cost, we need to find the values of K and L that minimize the total cost function while satisfying the production constraint q = 1000KL.

The expansion path of the firm represents the combinations of K and L that minimize the cost at different production levels q.

The bottom part of this block is a rectangular prism. you would need 188 cm² of paper to cover the block entirely.

To calculate the amount of paper needed to cover the block entirely, we need to find the surface area of both the rectangular prism and the square pyramid and add them together.

Let's start with the rectangular prism:

The rectangular prism has a base of length 5 cm and width 4 cm, and a height of 6 cm. It has three pairs of identical faces: two pairs of rectangles with dimensions 5 cm by 4 cm (base and top), and one pair of rectangles with dimensions 5 cm by 6 cm (sides). So, the total surface area of the rectangular prism is:

2(5 cm * 4 cm) + 2(5 cm * 6 cm) + 2(4 cm * 6 cm) = 40 cm² + 60 cm² + 48 cm² = 148 cm²

Next, let's consider the square pyramid:

The square pyramid has a base of side length 5 cm and a height of 4 cm. It has four triangular faces with the base formed by the sides of the square pyramid and the height equal to the height of the pyramid.

The area of each triangular face can be calculated using the formula: ½ * base * height.

The base of each triangular face is 5 cm, and the height is 4 cm. Therefore, the area of each triangular face is:

½ * 5 cm * 4 cm = 10 cm²

Since there are four triangular faces, the total surface area of the square pyramid is:

4 * 10 cm² = 40 cm²

To find the total paper needed to cover the entire block, we add the surface areas of the rectangular prism and the square pyramid:

148 cm² + 40 cm² = 188 cm²

Therefore, you would need 188 cm² of paper to cover the block entirely.

Population Proportion(p) = 0.3

q = 1 - 0.3

q = 0.7

σ = √npq

σ = √(525 × 0.3 × 0.7)

σ = √110.25

σ = 10.5

Step-by-step explanation:

we would like to solve the following trigonometric equation:

\( \displaystyle 6 { \sin}^{2} ( \theta) + 7 \sin( \theta) + 2 = 0\)

to do so we can let sinθ be u so it'll be easier to solve:

\( \displaystyle 6 { u}^{2} + 7 u + 2 = 0\)

to notice is that it's a quadratic equation to solve the equation we can consider factoring method in this method we rewrite the middle term as sum or substraction of two different terms in that case 3u+4u can be mentioned:

\( \displaystyle 6 { u}^{2} +3u + 4u + 2 = 0\)

(continuing the method) well we can factor out the common terms and that yields:

\( \displaystyle 3u(2 { u}^{} +1) + 2(2u + 1)= 0\)

group:

\( \displaystyle (3u+ 2)(2u + 1)= 0\)

by Zero product property we acquire:

\( \begin{cases}\displaystyle 3u+ 2 = 0 \\ 2u + 1= 0 \end{cases}\)

solve the equation for u:

\( \begin{cases}\displaystyle u = - \frac{2}{3} \\ \\ u= - \dfrac{1}{2} \end{cases}\)

substitute back:

\( \begin{cases}\displaystyle \sin( \theta) = - \frac{2}{3} \\ \\ \sin( \theta) = - \dfrac{1}{2} \end{cases}\)

take inverse trig in both sides and that yields:

\( \begin{cases}\displaystyle \theta = - {41.8}^{ \circ}, {221.8}^{ \circ} \\ \\ \theta = {210}^{ \circ} , {330}^{ \circ} \end{cases}\)

add period of 2nπ:

The value of ∠ABD is 120 degrees if given an isosceles trapezoid ABCD with median XY

What is trapezoid ?

A trapezoid is a quadrilateral (a four-sided polygon) with at least one pair of parallel sides. The parallel sides of a trapezoid are called bases, and the non-parallel sides are called legs.

Since ABCD is an isosceles trapezoid, the length of AB is equal to the length of CD. Let's assume that AB = CD = a, and BC = d.

The length of XY is equal to half the sum of the lengths of the non-parallel sides AB and CD. Therefore, XY = (1/2)(AB+CD) = (1/2)(a+a) = a.

So, the length of the median XY is a.

Since ABCD is an isosceles trapezoid, the base angles A and D are congruent. Let's assume that m∠ABD = x.

Since XY is the median of ABCD, it bisects the legs AB and CD at M and N, respectively. Therefore, AM = MB = (AB/2) and DN = NC = (CD/2).

Since AD and BC are parallel, we have ∠AMB = ∠DNC (corresponding angles). Also, ∠AMB + ∠BMD = 180° (linear pair), so ∠BMD = 180° - ∠AMB.

Similarly, we have ∠CND + ∠DNC = 180° (linear pair), so ∠CND = 180° - ∠DNC.

Since AD and BC are parallel, we have ∠ABD + ∠BMD = 180° (co-interior angles), so ∠ABD = 180° - ∠BMD.

Similarly, we have ∠DCB + ∠CND = 180° (co-interior angles), so ∠DCB = 180° - ∠CND.

Since ABCD is an isosceles trapezoid, we have AB = CD, so AM + MC = DN + NB. Substituting the values, we get (a/2) + d = (a/2) + d. Therefore, d = d.

Now, we can use the fact that ∠BMD = ∠CND to get an equation in terms of x: x + ∠ABD = 180° - x + ∠DCB. Substituting d = d, we get x + ∠ABD = 180° - x + ∠ABD. Therefore, x = (1/2)*(180° - ∠ABD).

Since ABCD is an isosceles trapezoid, we have ∠ABC = ∠DCB. Also, we know that ∠ABD and ∠CBD are supplementary angles. Therefore, ∠ABD + ∠CBD = 180°. Substituting the value of x, we get (1/2)*(180° - ∠ABD) + ∠ABD = 180°. Simplifying, we get ∠ABD = 120°.

Therefore, The value of ∠ABD is 120 degrees if given an isosceles trapezoid ABCD with median XY

Step-by-step explanation:

Answer:

a=4, b = 12

Step-by-step explanation:

This is a relatively simple question once you break it down. Make two equations based on the rectangles given:

64 = 4b + 4a

56 = 8a + 2b

64 = 4b + 4a => 64 = 4 (b+a) => 16 = b + a

isolate for a variable (any will do I just chose b)

16 - a = b

56 = 8a + 2b => 56 = 2(4a + b) => 28 = 4a + b

isolate for b then plug in equation

28 - 4a = b

16 - a = 28 - 4a

28 - 16 = -a + 4a

12 = 3a

4 = a

16 - a = b

b = 16 - 4

b = 12

Assuming my math is right, this should be your answer

To find an equation of the line perpendicular to the line 4x - 3y = 12 and passing through the point (-8, 1), we can start by determining the slope of the given line.

The equation 4x - 3y = 12 can be rewritten in slope-intercept form as y = (4/3)x - 4. The perpendicular line will have a slope that is the negative reciprocal of the slope of the given line.

Therefore, the perpendicular line will have a slope of -3/4. Using the point-slope form of a linear equation, we can plug in the slope and the coordinates of the given point to find the equation. Thus, the equation of the line perpendicular to 4x - 3y = 12 and passing through (-8, 1) is y - 1 = (-3/4)(x + 8).

To find an equation of a line perpendicular to a given line, we need to consider the slope of the given line. The slope of the perpendicular line will be the negative reciprocal of the slope of the given line.

Given the equation 4x - 3y = 12, we can rearrange it to slope-intercept form, which is y = (4/3)x - 4. The slope of this line is 4/3.

To find the slope of the perpendicular line, we take the negative reciprocal of 4/3, which gives us -3/4.

Next, we use the point-slope form of a linear equation, which states that y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Plugging in the values of the point (-8, 1) and the slope -3/4 into the point-slope form, we get y - 1 = (-3/4)(x + 8).

This equation can be further simplified to obtain the final answer, either in the point-slope form or by rearranging it to slope-intercept form, depending on the desired representation of the equation.
