Answer: 10

Step-by-step explanation:

The correct option is: (x + 3)² = 17; x equals negative 3 plus or minus the square root of 17(x = -3 ± √17) by completing the square

The completing the square method require we move constant term to the right hand side of the equation, divide the middle term and add its square to both sides of the equation as follows:

For the equation;

x² + 6x - 8 = 0

add 8 to both sides

x² + 6x = 8

divide 6 by 2 and add the square of the result to both sides

x² + 6x + 3² = 8 + 3²

by factorization;

(x + 3)² = 8 + 9

(x + 3)² = 17

x + 3 = ± √17 {take square root of both sides}

x = -3 ± √17

Therefore, by completing the square we the equation to be (x + 3)² = 17 and the solution for the value of x = -3 ± √17

The length f the diagonal of the square is

The marked points represents the diagonal hence we find the distance between the points

The distance between them is calculated using the following formula:

d = √((x₂ - x₁)² + (y₂ - y₁)²)

Using the points (3, 5) and (12, 14), we can substitute the values into the formula and calculate the length of the line segment:

d = √((12 - 3)² + (14 - 5)²)

= √(9² + 9²)

= √(81 + 81)

= √162

≈ 12.73

Therefore, the length of the line segment between (3, 5) and (12, 14) is approximately 12.73 units.

The apothem of the hexagon is 8√3 cm.

We are given that;

The area of a regular hexagon= 384√3Cm²

Now,

To find the side length, radius, and apothem of a regular hexagon given its area, we can use the following formulas:

Area = (3√3 s^2) / 2 Area = (1/2) a P Area = (3/2) r a

where s is the side length, a is the apothem, P is the perimeter, and r is the radius of the hexagon. We can solve for any of these variables by rearranging the formulas and plugging in the given area.

A. To find the side length, we can use the first formula and solve for s:

s^2 = (2 Area) / (3√3) s = sqrt((2 Area) / (3√3))

Plugging in Area = 384√3, we get:

s = sqrt((2 * 384√3) / (3√3)) s = sqrt(256) s = 16

Therefore, the side length of the hexagon is 16 cm.

B. To find the radius, we can use any of the formulas and solve for r. For example, using the third formula, we get:

r = (2 Area) / (3 a)

To find a, we can use the second formula and solve for a:

a = (2 Area) / P

To find P, we can use the fact that P = 6s and plug in s = 16:

P = 6 * 16 P = 96

Plugging in P and Area into the formula for a, we get:

a = (2 * 384√3) / 96 a = 8√3

Plugging in a and Area into the formula for r, we get:

r = (2 * 384√3) / (3 * 8√3) r = 32

Therefore, the radius of the hexagon is 32 cm.

C. To find the apothem, we can use any of the formulas and solve for a. For example, using the second formula, we get;

a = (2 Area) / P

Plugging in Area = 384√3 and P = 96, we get:

a = (2 * 384√3) / 96 a = 8√3

Therefore, by polygon the answer will be 8√3 cm.

The value of ∠N is 54.38 degrees.

Given that in ΔNOP, n = 56 inches, p = 61 inches and ∠P=80°.

We need to find the value of ∠N,

According to the cosine rule, the following equation is true for every triangle with sides a, b, and c and the corresponding opposite angles A, B, and C:

c² = 2ab cos(C) - a² + b²

In this instance, we have:

A = P and B = P

C = ∠P

When we enter the values, we obtain:

n² = p² + p² - 2p² cos(∠P)

Substituting the known values:

56² = 61² + 61² - 2(61²) cos(80°)

Simplifying:

3136 = 3721 + 3721 - 2(3721) cos(80°)

3136 = 3721 + 3721 - 7442 cos(80°)

Now we can solve for cos(80°):

3136 = 7442 - 7442 cos(80°)

7442 cos(80°) = 7442 - 3136

cos(80°) = (7442 - 3136) / 7442

cos(80°) ≈ 0.5798

Step-by-step explanation:

For finding the surface area of this rectancular prism, or any, we find the area of each shape. Then, we add up all of the areas together to get the surface area. There are 2 squares with 2 as a side length for each side. To find the area of a square, we can multiply any 2 sides. That is because the sides of the square is equal to eachother, so 2•2=4. Being 2 squares, they are both have area of 4. Looking at the 4 rectangles, they have a length of 4 and a width of 2. We multiply the height and width of a rectangle to get the area. 4•2=8, the area of each rectangle is 8. Now, we add up all of our areas. Two squares, each are 4 for their area. Add them up, you get 8 for the 2 squares. Then, we have 4 rectangles each are 8 for their area. 4•8=32 since they all have the same area. 32+8=40! 40 is the surface area of this net.

If you get a perfect score of 100% on both assignments, your overall grade in the class would be 100%.

To calculate your grade, we need to consider the weight of each assignment.

Since each assignment is worth 5% of your grade, we can calculate the contribution of the assignments to your overall grade.

The total weight of the two assignments is 2×5% = 10%.

To find the impact of the assignments on your grade, we multiply your average score on the assignments (100%) by their weight (10%):

Contribution from the assignments = 100% * 10% = 10%

Since you currently have a grade of 79, the remaining 90% of your grade is based on other assessments, tests, or assignments.

To calculate your overall grade, we add the contribution from the assignments to the remaining 90%:

Answer:

To find the slope of a line passing through four points, we can use the formula:

slope = (change in y) / (change in x)

We can use any two points to calculate the slope, but since we need to find the slope for the entire line passing through all four points, we need to make sure that the slope is the same for any two points that we choose.

Let's use the points (-6,7) and (-2,6) to calculate the slope:

slope = (6 - 7) / (-2 - (-6)) = -1/4

Now let's use the points (2,5) and (6,4) to calculate the slope:

slope = (4 - 5) / (6 - 2) = -1/4

Since the slope is the same for both pairs of points, we can conclude that the slope of the line passing through all four points is -1/4.

hello

the answer to the question is:

y = a cot(bx – c) + d

a = 1, b = 1/2, c = 0

the midline is y = d, so y = 0

the vertical stretch is 1, so label the y-axis so the inflection point of the curve is 1 above the midline, and the other inflection point is 1 below the midline

the period is:

T = π/b ----> T = 2π

the phase shift is:

PS = c/b ----> PS = 0

and also, there's no amplitude for tangent and cotangent, there is only the vertical stretch that takes the place of an amplitude

Answer:

amplitude does not exist. period = 2π (360°)

The surface area of the box increases by 27.4 cm² when the height is increased by 0.2 cm.

To find the increase in surface area, we first need to calculate the initial surface area of the box and then calculate the surface area after increasing the height.

The formula for the surface area of a rectangular prism is given by:

Surface Area = 2*(length width + length height + width*height)

Initial Surface Area:

Length (L) = 13 cm

Width (W) = 8.7 cm

Height (H) = 28 cm

Initial Surface Area = 2*(138.7 + 1328 + 8.7*28)

Next, we calculate the new surface area after increasing the height by 0.2 cm. The new height is:

New Height = Initial Height + Increase in Height = 28 cm + 0.2 cm

New Surface Area = 2*(138.7 + 13(28+0.2) + 8.7*(28+0.2))

To find the increase in surface area, we subtract the initial surface area from the new surface area:

Increase in Surface Area = New Surface Area - Initial Surface Area

Let's calculate the values:

Initial Surface Area = 2*(138.7 + 1328 + 8.728) = 2(113.1 + 364 + 243.6) = 2*(720.7) = 1441.4 cm²

New Surface Area = 2*(138.7 + 13(28+0.2) + 8.7*(28+0.2)) = 2*(113.1 + 377.2 + 244.1) = 2*(734.4) = 1468.8 cm²

Increase in Surface Area = New Surface Area - Initial Surface Area = 1468.8 cm² - 1441.4 cm² = 27.4 cm²

Therefore, the surface area of the box increases by 27.4 cm² when the height is increased by 0.2 cm.

We will use the following equation, x² + y² = 81, where x and y are the pool's dimensions in feet, to determine the necessary estimations for the pool project.

1. Calculate the pool's diameter and radius:

We can infer that the radius of the pool is equal to the square root of 81 because the equation depicts a circle. As a result, r = 81 = 9 ft.

The pool's diameter is simply equal to twice its radius, or d = 2r = 18 feet.

2. Calculate the amount of water in the pool:

Since the pool is 4 feet high, we can determine its volume by multiplying the area of its circle-shaped base by the height.

The formula A = πr² can be used to calculate the area of the pool's base,

Therefore, V = Ah = πr²h = 1017.87 cubic feet represents the volume of water in the pool.

3. Determine the pool's total material cost:

There are 7.48 gallons in a cubic foot and a gallon of water costs $0.22.

As a result, Cw = V × 7.48 × 0.22 = 1017.87 × 7.48 × 0.22 = $1,619.72 is the entire cost of water for the pool.

If the radius of the pool is $185 per foot, then the cost of the materials is Cm = r × 185 = 9 × 185 = $1,665.

4. Calculate the pool's total labour hours:

A pool's construction is estimated to take 2.5 hours for every foot of its radius.

So, L = r × 2.5 = 9 × 2.5 = 22.5 hours of labour would be needed to complete this pool.

5. Calculate the total cost of labour for the project:

If you pay someone $19 per hour, Cl = L × 19 = 22.5 × 19 = $427.5.

6. Find the project's overall cost:

The project's overall cost is the product of its labour and material costs:

Cost as a whole equals Cm + Cw + Cl, which is 1,665 + 1,619.72 + 427.5, or $3,712.22.

In conclusion, the pool has an 18-foot diameter and a 9-foot radius according to the supplied equation. There are roughly 1017.87 cubic feet of water in the pool. Water and building supplies are included in the pool's projected material cost of $3,284.72. 22.5 hours of labour in total are needed, with a labour cost estimate of $427.5. Consequently, $3,712.22 is the expected final cost of the pool renovation.
