The coordinates of B are (-7,-2).

What do you mean by x and y coordinates?

The x and y coordinates are a component of the x-axis and y-axis in a 2D space in the Cartesian coordinate system. The x and y coordinates for a point in space are expressed as an ordered pair (x, y). The position of the point on the x-axis is shown by the first number, while its location on the y-axis is indicated by the second number.

According to the given data in the question,

if M is the location where line segment AB meets its midpoint.

Then, we will using the midpoint formula,

\((-5,2)=(\frac{-3+x}{2},\frac{6+y}{2})..............(1)\)

Putting the x-coordinates in (1),

\(-5=\frac{-3+x}{2}\\ -10=-3+x\\-10+3=x\\x=-7\)

Similarly, putting the y-coordinates in (1),

\(2=\frac{6+y}{2} \\4=6+y\\4-6=y\\y=-2\)

Hence, the coordinates of B are (-7,-2).

The maximum error of estimate with a sample of 300 cell phones is 29.73%

The formula for calculating the maximum error of the estimate is expressed as:

ME = √0.25/n

n is the total sample

Given the following parameters

n = 300

Substitute into the formula to have:

ME = √0.25/n

ME = √0.25/300
ME = 0.2973
ME = 29.73%

Hence the maximum error of estimate with a sample of 300 cell phones is 29.73%

Answer:

y = 0.07n + 0.2

Step-by-step explanation:

y = mx + b

m: slope → amount cost is increasing

b: y-intercept → the cost at 0 minutes

cost is increasing by (m): 0.07 cost increase by minute

Time at 5 minutes + the amount cost increase = Time at 5 minutes

0.55 + m = 0.62

-0.55           -0.55         m = 0.07

Time at 6 minutes + the amount cost increase = Time at 5 minutes

0.62 + m = 0.69

-0.62          -0.62         m = 0.07

....and so on

the cost at 0 minutes (b): 0.2 is the cost at 0 minute (start)

cost at n minutes

= cost is increasing by (m) x n of minutes + cost at 0 minutes (b)

cost at 5 minutes

= cost is increasing by (m) x 5 minutes + cost at 0 minutes (b)

0.55 = 0.07 x (5) + b

 0.55 = 0.35 + b

- 035   - 035

b = 0.2

Our initial assumption that S is non-empty must be false. Therefore, for every x ε W, f(x) < x.

To prove the given statement, let's assume that (W, <) is a well-ordered set and f: WW is an increasing function. We need to show that f(x) < x for each x ε W.

Since (W, <) is a well-ordered set, every non-empty subset of W has a minimum element. Let's consider the set S = {x ∈ W | f(x) ≥ x}. Suppose S is non-empty.

By the well-ordered property of (W, <), S has a minimum element, let's call it a. Since a is the minimum element of S, it implies that for all x < a, f(x) < x, because if f(x) ≥ x for any x < a, then x would be an element of S smaller than a, contradicting the assumption that a is the minimum element of S.

Now, let's consider f(a). Since f is an increasing function, f(a) ≥ f(x) for all x < a. But we also know that f(x) < x for all x < a. Combining these two inequalities, we get f(a) < x for all x < a, which means f(a) is an element of S smaller than a, contradicting the assumption that a is the minimum element of S.

The height of the cylinder whose surface area is given would be = 85 yards.

The cylinder is a type of shape that has three sides which consists of two opposite circles that are joined by a curved surface.

To calculate the height of a cylinder, the formula that should be used is given as follows:

Surface area of cylinder = 2πrh + 2πr²

radius = 29 yards

surface area = 20,761.68 square yards

height = ?

That is ;

20,761.68 = 2×3.14× 29×h + 2×3.14× 29×29

20,761.68 =182.12h + 5281.48

182.12h = 20,761.68-5281.48

182.12h = 15480.2

h = 15480.2/182.12

The surface area οf the square prism after increasing the length by a factοr οf 3 is 1400 square units.

The surface area οf a sοlid is defined as the sum οf the areas οf each οf its faces (οr surfaces), hence the name.

Let's say the οriginal dimensiοns οf the square prism are l x w x h, where l = w = h = 10 (since it is a square prism). After increasing the length by a factοr οf 3, the new dimensiοns becοme 3l x w x h.

The surface area οf a rectangular prism can be calculated using the fοrmula:

SA = 2lw + 2lh + 2wh

Substituting the new dimensiοns, we get:

SA' = 2(3l)(w) + 2(3l)(h) + 2(w)(h)

SA' = 6lw + 6lh + 2wh

Nοw we can substitute l = w = h = 10 and simplify:

SA' = 6(10)(10) + 6(10)(10) + 2(10)(10)

SA' = 600 + 600 + 200

SA' = 1400

Therefοre, the surface area οf the square prism after increasing the length by a factοr οf 3 is 1400 square units.

Answer:

B(6, 5), C(1, -7)

Step-by-step explanation:

A(2, 5)

From A to B, there is translation x, (4, 0).

Add 4 to A's x-coordinate, and add 0 to A's y-coordinate.

B(2 + 4, 5 + 0) = B(6, 5)

From C to B there is the translation y, (5, 12).

Since we are going from B to C, we undo translation y.

The translation from B to C is (-5, -12).

Answer:  $4,000

Step-by-step explanation:

If the total earnings were $40,000 and the base pay was $10,000, then the commission earned would be $40,000 - $10,000 = $30,000.

Since the commission rate is 40%, we can set up the equation:

40% x Total Sales = Commission Earned

We know that the commission earned is $30,000, and we also know that 15 cars were sold. Therefore, we can solve for the average price of each car:

40% x Total Sales = Commission Earned

40% x (15 x Price per Car) = $30,000

6 x Price per Car = $30,000

Price per Car = $5,000

However, this is just the average price per car. Since the commission is based on the total sales, we need to calculate the actual commission earned on each car:

Commission per Car = 40% x Price per Car

Commission per Car = 40% x $5,000

Commission per Car = $2,000

Therefore, the total earnings of $40,000 divided by the number of cars sold (15) gives the amount earned per car:

Amount earned per Car = Total Earnings / Number of Cars Sold

Amount earned per Car = $40,000 / 15

Amount earned per Car = $4,000

The boundary line follows the graph of y = 2x - 4 because it represents the line of maximum or minimum values the graph could take. y = 2x - 4 has a y-intercept of -4 because it is in slope-intercept form. It also has a slope of 2, so to find another point on the line, you can go up two and right one. Also, this inequality has a solid line because it is "less than or equal to" and a solid line represents the values that equal.

Answer:

The other factor is 12⇒ A

Step-by-step explanation:

The factors of a number are all the numbers multiplied to form this number

Examples:

The factors of 12 are 1, 2, 3, 4, 6, 12 because

1 × 12 = 12

2 × 6 = 12

3 × 4 = 12

∵ The product of numbers = 1236

∵ One factor of that number is 103

∴ ------ × 103 = 1236

→ Divide the number by its factor to find the other number

∴ 1236 ÷ 103 = -------

∵ 123 ÷ 103 = 1 R 20

∵ 206 ÷ 103 = 2

∴ 1236 ÷ 103 = 12

∴ The other factor is 12

Step-by-step explanation:

Since we need to leave 2 cm of room on both sides, the maximum width of TV is 136 - 2 - 2 = 132 cm. Next, use the Pythagorean Theorem, a^2 + b^2 = c^2, to find the diagonal.

132^2 + 86^2 = c^2

c^2 = 17424 + 7396

c^2 = 24820

c = 157.543644746 cm
