P is the weighted average of point C and D. Find the coordinates of P under the given conditions

Answer:

80 miles per hour.

Step-by-step explanation:

120 - 80 = 40 Because 40 is half than 80.

The ratio of the cost price and the printed price of the book is 1.2444.

We have,

Let's assume the printed price of the book = P.

As per the problem, the shopkeeper is selling the book at a discount of 10% on the printed price. So the selling price of the book.

= (P - 0.1P)

= 0.9P.

The shopkeeper earns a profit of 12% on selling the book.

So, the selling price of the book is also 112% of the cost price.

That is,

0.9P = 1.12C

where C is the cost price of the book.

Now, let's find the ratio of the cost price and the printed price of the book:

C/P

= (C/0.9P)/(P/0.9P)

= 1.12/0.9

= 1.2444

Therefore,

The ratio of the cost price and the printed price of the book is 1.2444.

An equation for the line that passes through (-14, 14) and whose slope is undefined is x = -14.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical expression:

y - y₁ = m(x - x₁)

Where:

At data point (-14, 14) and an undefined slope, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 14 = undefined(x - (-14))

y - 14 = undefined(x + 14)

x = -14

In conclusion, the equation of a line that has an undefined slope represents a vertical line that crosses the x-axis only i.e x = -14.

By completing squares, we can rewrite the quadratic equation as:

(x + 9)^2 = -9

Remember the perfect square trinomial:

(a + b)^2 = a^2 + 2ab + b^2

Here we have the quadratic equation:

x^2 + 103 = -18x + 13

We can rewrite this as:

x^2 + 18x = 13 - 103

x^2 + 18x = -90

x^2 + 2*9*x = -90

We can add 9^2 and subtract 9^2 to get:

x^2 + 2*9*x + 9^2 - 9^2= -90

(x^2 + 2*9*x + 9^2) - 9^2= -90

(x + 9)^2 - 81 = -90

(x + 9)^2 = -90 + 81

(x + 9)^2 = -9

The angle formed between this vector and the positive x-axis measures around 61.26° and goes in a counterclockwise direction.

First, we calculate the components:

u = (80cos(30°), 80sin(30°)) ≈ (69.28, 40.00)

v = (60cos(60°), 60sin(60°)) ≈ (30.00, 51.96)

w = (50cos(120°), 50sin(120°)) ≈ (-25.00, 43.30)

Now, let's find the resultant vector (u+v+w):

u+v+w = (69.28 + 30.00 - 25.00, 40.00 + 51.96 + 43.30) ≈ (74.28, 135.26)

The magnitude of the resultant vector ||u+v+w|| can be found using the Pythagorean theorem:

||u+v+w|| = √(74.28² + 135.26²) ≈ 152.44

To find the direction, we calculate the angle θ:

θ = atan2(135.26, 74.28) ≈ 61.26°

The total size of the composite vector, obtained by adding u, v, and w, amounts to a value close to 152.44.

Step-by-step explanation:

2.50/10

there is only one zero in 10 so we move the decimal one digit towards left.

which then the decimal ends up in front of 2.

Answer:

Step-by-step explanation:

The sum of angles in a quadrilateral is 360 degrees. So, we have:

x + 2x + 3x + fourth angle = 360

6x + fourth angle = 360

fourth angle = 360 - 6x

To find the value of x, we can use the fact that the angles in a quadrilateral add up to 360 degrees:

x + 2x + 3x + (360 - 6x) = 360

6x + 360 - 6x = 360

360 = 360

This equation is true for any value of x, so we cannot solve for x.

To find the size of the largest angle, we can substitute any value of x into the expression for the fourth angle and then find the largest of the four angles. For example, if we choose x = 30, then the angles are:

x = 30 degrees

2x = 60 degrees

3x = 90 degrees

fourth angle = 360 - (x + 2x + 3x) = 180 degrees

So the largest angle is 180 degrees.

Answer:

The cost of one share of the stock on Friday is $41.45

Step-by-step explanation:

The initial cost of one share of the stock on Monday is $41.45.

On Tuesday, the cost goes up by $0.58, so the cost becomes:

$41.45 + $0.58 = $42.03

On Wednesday, the cost goes down by $0.26, so the cost becomes:

$42.03 - $0.26 = $41.77

On Thursday, the cost also goes down by $0.26, so the cost becomes:

$41.77 - $0.26 = $41.51

Finally, on Friday, the cost goes down by $0.06.

So the expression to represent the cost of one share of the stock on Friday is:

$41.51 - $0.06

To evaluate this expression, we simply subtract $0.06 from $41.51:

$41.51 - $0.06 = $41.45

Therefore, the cost of one share of the stock on Friday is $41.45

The measures of the angles add up to 180°, using that we can see that x = 10.

Here we can see that the two vertical lines are parallel, thus, the angles in both intersections are equal.

Now, notice that the 75° angle would be an adjacent angle to (11x - 5)°, then their measures add up to 180°, then we can write:

75° + (11x - 5)° = 180°

We can solve that for x.

75 + 11x - 5 = 180°

70 + 11x = 180

11x = 180 - 70 = 110

x = 110/11

x = 10

That is the value of x.

Given data ,

Let the amount of commission earned be C

Now , the equation is

The first $1,500 in sales are eligible for a commission rate of 21%, so the commission on this portion of his sales is:

0.21 x $1,500 = $315

The remaining portion of his sales is:

$2,233 - $1,500 = $733

This amount is eligible for a commission rate of 14%, so the commission on this portion of his sales is

On simplifying the equation , we get

0.14 x $733 = $102.62

The local maximum of f is at (-5/3, 128/27), and the local minimum is at (4/3, -64/27).

To find the neighborhood maxima and minima of the capability f(x) = (x-3)(x+1)(x+4), we really want to take its subordinate:

f'(x) = (x+1)(x+4) + (x-3)(x+4) + (x-3)(x+1)

f'(x) = [tex]3x^2 + 6x - 20[/tex]

Setting f'(x) equivalent to nothing and settling for x, we get:

[tex]3x^2 + 6x - 20 = 0x^2 + 2x - 20/3 = 0(x+5/3)(x-4/3) = 0[/tex]

Thusly, the basic focuses are x=-5/3 and x=4/3.

To decide the time periods and diminishing, we can utilize the principal subsidiary test. Since f'(x) is a quadratic capability with a positive driving coefficient, it is dependably certain for x < - 5/3 and x > 4/3, and consistently negative for - 5/3 < x < 4/3.

Thusly, f(x) is expanding on the spans (- ∞, - 5/3) and (4/3, ∞), and diminishing on the stretch (- 5/3, 4/3).

To find the nearby maxima and minima, we can utilize the subsequent subsidiary test. Taking the subordinate of f'(x), we get:

f''(x) = 6x + 6

Subbing x=-5/3 and x=4/3, we get:

f''(- 5/3) = - 2 < 0, so f has a neighborhood greatest at x=-5/3.

f''(4/3) = 10 > 0, so f has a neighborhood least at x=4/3.

Thusly, the neighborhood limit of f is at (- 5/3, 128/27), and the nearby least is at (4/3, - 64/27).

A function f(x) = (x⁴ - 5x² + 4) / (x² + x - 2) is discontinuous at  x = 1 and x = -2. And it is a removable discontinuity.

Consider function f(x) = (x⁴ - 5x² + 4) / (x² + x - 2)

We factorise denominator as,

x² + x - 2

= x² + 2x - x - 2

= x(x + 2) - 1(x  + 2)

= (x  + 2)(x - 1)

So, the function f(x) becomes,

f(x) = (x⁴ - 5x² + 4) / ((x  + 2)(x - 1))

A function f(x) is discontinuous when the denominator of f(x) is zero.

i.e.,  (x  + 2)(x - 1) = 0

i.e., x = 1 or x = -2

Also, the factors of the polynomial x⁴ - 5x² + 4 are (x - 2), (x  + 2), (x - 1) and (x + 1)

We can write function f(x) as,

f(x) = (x⁴ - 5x² + 4) / (x² + x - 2)

f(x) = ((x - 2) (x  + 2) (x - 1) (x + 1)) / ((x  + 2)(x - 1))

f(x) = (x - 2)(x + 1)
