Based on the amount you paid for the shares and the selling price as well as the number of years, the total return would be -51.9%

The annual return would be -16.7%

The total return on the stock can be found by finding the difference in stock prices for the 4 years and dividing by the buying price:

= (1,300 - 2,700) / 2,700 x 100%

= -1,400 / 2,700 x 100%

= 0.51851851851851851851851851851852  x 100%

= -51.9%

The annual return can be found as:

= ((1,300 / 2,700) ^ 1/4  - 1) x 100%

= -16.7%

You have to perform two transformations the first one is a 180º rotation with respect to the origin r(180º,O) and the second one is a translation of one unit left and 5 units up T(-1,5)

Given point A(8,-6)

To make a 180º rotation you have to invert the signs of both coordinates, following the rule:

For point A, the rotation is the following:

Once you rotate the point, you have to perform the translation T(-1,5). The rule for the translation can be expressed as follows

So, the translation of point (-8,6) is:

Using the vector form of velocity, it is possible to calculate the airspeed and bearing, which are 165.33 mph and 0.7 degrees respectively.

Given:

A plane may go 360 miles straight north in 2.0 hours if the wind is blowing at 15 mph and 331 degrees from the north.

You can use the following formula to calculate airspeed.

[tex]V^{2} =V_{x} ^{2} + V_{y} ^{2}- 2v_{x} v_{y}cos\beta \\[/tex] ...........equation (1)

[tex]v_{x}[/tex] is the velocity of the wind and [tex]v_{y}[/tex] is the velocity of the plane.

[tex]\beta = 331-180 = 151 degree[/tex]

Putting [tex]v_{x}, v_{y} , \beta[/tex] in equation (1)

[tex]V^{2}= 15^{2} +180^{2} -2*15*180*cos151\\ V^{2} = 225 + 32400 - 5400*cos151\\V^{2} = 27336.49\\V = 165.33[/tex]

Hence, The airspeed of the plane is 165.33 mph

Now,

[tex]\frac{sin\alpha }{v_{x} } =\frac{sin\beta }{V} \\\frac{sin\alpha }{15 } =\frac{sin151 }{165.33} \\\\sin\alpha = 10*0.00122\\\alpha = 0.7[/tex]

Hence bearing required is 0.7 degrees.

We get from the question the following equation:

S = d/t

We have the following informations:

Speed(S) = 75 miles /h

Distance(d) = 187.5 miles

If you plug those informations into the formula, you'll get the following:

75 miles/h = 185.5 miles/ t

Now, you just have to solve for "t". If you invert the equation, you'll get(I'm going to omit the units, to make it clearer, but don't forget about them!)

1/75 = t / 185.5

If you multiply both sides by 185.5, you'll get

185.5/75 = t

Solving this calculation, we get the final solution!

t = 185.5/75 hours = 2.47 hours

Hence, the square root of 225 is 15

Given that,

base salary = b = 5000$

Comission rate = 6% = 0.06

Let's say, the sales are = x

As given in the question, he receives 6% commission on all sales over $8000.

Hence, the commissionable amount is (x - 8000) '.' x - 8000 shows the amount greater than 8000, which receives a commission.

hence, gross income will be

base salary + commission * (commisonable amount)

=> 5000 + 0.06 * (x - 8000)

Using the sine formula;

sin 60 / x = sin 90 / 16

cross-multiply

x sin 90 = 16 sin 60

Divide both-side of the equation by sin 90

x = 16 sin 60 /sin 90

x= 13.86

To find y, we can simply use the Pythagoras theorem

opp² + adj² = hyp²

13.86² + y² = 16²

192.0996 + y² =256

subtract 192.0996 from both-side of the equation

y² = 256 - 192.0996

y² = 63.9004

Take the square root of both-side

y = 7.99

Area of square = L x L

12sq feet =L x L

So the first step is to solve the multiplication "4*2" and the division "10÷2"

Now all that is left is to add the numbers when you have to perform the same operation several times, you have to solve them from lef

Given:

The slopr of line is m = -7.

The line passes through point (-6,8).

Explanation:

The equation of line in slope-intercept form is,

Substitute the valus in the equation to determine the value of c.

So equation of line is y = -7x - 34.

We illustrate the division of fractions by taking the example below.

The first step is to change the division sign to multiplication by changing the fraction after the division sign.

Next, we multiply the numerators together and the denominators together.

You then simplify by dividing common factors.

The equation of the line woth slope 0 and passing through (-9,7) in slope-intercept form is y = 7.

If a line L has a slope M and it has the intercept c, then the equation of the line L can be written in the point slope form as,

L : y = Mx + c

This above equation of line is known as slope-intercept form of line.

Here, we have to find the equation of line which has slope m equal to zero and passing through (-9,7).

putting the known values in y = mx+c

y = (0)x+ c

y = c

Putting the value of y = 7

c = 7

Here, we have,

y = 7

So, the equation of the required line is y=7.

As we can se from the graph, the maximum value of the function is almost 15 meters, it is reached between t=1s and t=2s, and the height is 0 again when the time is approximately 3 seconds.

We can find the exact values by using the equation.

First, find the zeroes of the function by setting h(t)=0 and solving the quadratic equation for t:

Then, the projectile hits the ground at t=3s.

To find the time at which the projectile reaches its maximum height, find the average between both zeroes:

To find the maximum height, evaluate h at t=1.3s:

Therefore, to the nearest tenth, the projectile reached a maximum height of 14.5 meters in 1.3 seconds and it took 3.0 seconds for it to hit the ground.

The correct option is the second one.

The vehicle speed is 53 units if s = 24d and d = 245ft

Given the formula for speed is  =  √24 d

s denotes the vehicle's speed.

d = the length of the skid marks

We need to find the speed of the vehicle.

We know that the displacement d is 117 ft

d = 117 ft

And also it is mentioned in the question to use the below-given formula.

s = √24d

Now substituting the value of displacement in the formula we get

=> s = √24 x 117

=> s = √2808

=> s = 52.99

Now approximating to the nearest value of the decimal, we get.

=> s = 53

Therefore the speed of the vehicle is 53 units.

Answer:

25 more cups

Step-by-step explanation:

1. You need more than $636.00, but you already have $492.00. To find the needed amount of cups needed to sell, you need to find the difference of the two prices first. In other words, you need to subtract the total needed by the amount already raised.

2. You can get the equation, 636 - 492 = 144

3. Now that you have the amount needed, you can divide the number that you got (144) by 6. You divide it by 6 because that is the amount each cup costs.

4. After dividing 144 by 6, you should get 24. This gives your answer for getting EXACTLY 636. However, in this case, you need more to reach your goal. Since you cannot sell fractions of a cup, just raising it by one can reach your goal. We can add one to 24, making it 25.

In conclusion, you need to sell 25 more cups to reach your goal.

a)  Amount of paint needed for 200 km road = 6250 litres

b)  Length of road that can be painted by using 4000 litres of paint = 128 km

Amount of paint used for painting white lines on road= 250 litres

Length which was painted = 8 km

By using unitary method;

Thus for 1 km amount of paint required = 250/8

= 31.25 litres

a) Amount of paint needed for 200 km road = 31.25 × 200

= 6250 litres.

therefore, Amount of paint needed for 200 km road = 6250 litres

b) Since for 1 km 31.25 liters paint is required this implies with 1 liter = 1/ 31.25 =  0.032 km can be covered.

Length of road that can be painted by using 4000 litres of paint = 4000× 0.032

= 128 km

Thus, Length of road that can be painted by using 4000 litres of paint = 128 km

A single or unique unit is referred to as unitary. Determining values in relation to a single unit is the goal of this strategy. For instance, we can use the unitary technique to determine how many kilometers a car will go on one litre of gas if it travels 44 km on two litres of fuel.
