If a company’s stock was selling at 35$ a share a month later it was selling at 14$ a share the percentage loss is 60%

The company's initial share price = $35 per share

The company's new share price = $14 per share

Therefore the share price decreased from $35 to $14,  we have to find the percentage loss

The percentage loss = [(The company's initial share price - The company's new share price) / The company's initial share price ] × 100

Substitute the values in the equation

The percentage loss = [(35-14) / 35] × 100

= (21/35)×100

= 0.6 × 100

= 60%

Hence, if a company’s stock was selling at 35$ a share a month later it was selling at 14$ a share the percentage loss is 60%

What is Turns?

This is referred to as a cycle. It is a unit of plane angle measurement that is equivalent to 2π radians, 360 degrees, or 400 gradians.

formular for calculating Turns:

Turns =         Lenght

              Circumference

Circumference of a circle, C= πD

Where,

Diameter=D

            π =22/7

Calculating Circumference;

C= 22  * 66

What is perimeter?

A perimeter could be a closed path that encompasses, surrounds, or outlines either a 2 dimensional form or a one-dimensional length. The perimeter of a circle or an oval is termed its circumference.

Main body:

to find the perimeter we need the measurement of each side.

so length of DE side

DE = A F - BC

DE = 6-2

DE = 4 cm

so perimeter = 6+4+2+4+3

                     = 19 cm

area of figure =  area of rectangle ABCG + GDEF

area = 4*3 + 4*2

area of figure = 12+8

The function that can represent the graph is the option;

f(x) = x²·(x - a)²·(x - b)⁴·(x - c)

A function that only uses non-negative integer powers or only positive integer exponents of a variable in an equation is referred to as a polynomial function.

As, the graph touches the at x axis by 3 points.

So, the graph has an even multiplicity at three points as x², (x - a)², and  (x - b)⁴ .

Now, The function has a single zero or factor such as (x - c) in the first equation

3   $29,000   $18,560          $10,440           $4,176           $22,736   $6,264

What is the double-declining-balance method?

The double-declining-balance method is one of the depreciation methods in use, but it allocates more cost to the earlier years of the asset's life.

This depreciation method uses twice the straight-line rate, which is computed as the product of 100/estimated useful life multiplied by 2.

For each year's depreciation expense, the double rate is applied at the end of the year's balance.

For the last year, the difference between the previous year's ending balance and the residual value is taken as the depreciation expense.

Auto  = $29,000

Estimated useful life = 5 years

Residual = $2,000

Depreciable amount = $27,000 ($29,000 - $2,000)

Straight-line depreciation rate = 20% (100/5)

Double-declining depreciation rate = 40% (20% x 2)

Depreciation Expense:

1st year = $11,600 ($29,000 x 40%)

2nd year = $6,960 ($17,400 x 40%)

3rd year =  $4,176 ($10,440 x 40%)

4th year = $2,506 ($6,264  x 40%)

5th year = $1,758 ($3,758 - $2,000)

The time taken for the rocket to reach its maximum height by virtue of the information given is; 2.25 seconds.

The maximum height reached by the toy rocket is; 88 feet.

It follows from the task content that the maximum height reached by the rocket is to be determined.

The given function is; h (t) = -16 t² + 72t + 7.

Since it follows from evaluation that; at maximum height, the rate of change of height to time is equal to 0.

Therefore; at maximum height;

h'(t) = 0

h'(t) = -32t + 72 = 0

-32t = -72

t = -72/-32

t = 2.25 seconds.

Therefore, the time taken for the rocket to reach its maximum height is; 2.25 seconds.

Also, the maximum height reached by the rocket is at; h (2.25);

h(2.25) = -16(2.25)² + 72 (2.25) + 7

Yes Timothy is correct because triangle AKLM was dilated by a scale factor of 1.5 centered at the origin.

In Geometry, dilation simply refers to a type of transformation which changes the size of a geometric object based on the scale factor, but not its shape.

For the given vertices of triangle KLM, the dilation with a scale factor of 1.5 from the origin (0, 0) or center of dilation should be calculated as follows:

Point K (-1, 3) → Point K' (-1 × 1.5, 3 × 1.5) = Point K' (-1.5, 4.5).

Point L (8, 4) → Point L' (8 × 1.5, 4 × 1.5) = Point L' (12, 6).

Point M (10, -3) → Point M' (10 × 1.5, -3 × 1.5) = Point M' (15, -4.5).

In conclusion, the coordinates of the image triangle K'L'M after a dilation with a scale factor of 1.5 from the origin are (-1.5, 4.5), (12, 6), and (15, -4.5) as shown in the graph, and as such Timothy is correct.

The standard form equation

ax + by = c

y = mx + c ...... (1)

where m is the slope, b = y-intercept

y = 1/2x + 4

Slope (m) = 1/2

It passes through a line that has points (-3,4)

Let's find c by putting the value of x = -3 and y = 4 in equation (1).

4 = 1/2 (-3) + c

4 = -3/2 + c

c = 4 + 3/2

Angle 3: 126 degrees

Angle 4: 54 degrees

Step-by-step explanation:

since angle 1 is 126 degrees we can find angle 2 since it’s right next to it like that the 2 angles added equal 180 degrees so we just subtract from 180

180-126

Angle 2 is 54 degrees

Since angle 3 is across angle 1 they are equivalent so angle 3 is 126 degrees
