Answer:

Tano=x

Step-by-step explanation:

First, let's call sin(tan−1(x))=sin(θ) where the angle θ=tan−1(x) . More specifically, tan−1(x)=θ is the angle when tan(θ)=x

The circumference of ΔAOC, ΔAOB and ΔABC are  4√2(1+√2), 2(√5+3) and 2(3+√5+2√2) units respectively and area of ΔAOC, ΔAOB and ΔABC are 8,4 and 12 square units respectively.

The perimeter of a triangle can be calculated by simply adding the length of all the sides.

The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle. Basically, it is equal to half of the base times height, i.e. A = 1/2 × b × h.

There are three triangle in the given diagram namely ΔAOC, ΔAOB and ΔABC.

We will find the area and circumference of each of the triangle.

First we find area of each triangle.

Area of ΔAOC = 1/2*CO*AO = 1/2*4*4 = 8 square units.

Area of ΔAOB = 1/2*BO*AO = 1/2*2*4 = 4 square units.

Area of ΔABC = 1/2*BC*AO = 1/2*6*4 = 12 square units.

Now, we will find circumference of each triangle.

Since,  ΔAOC, ΔAOB are right angled triangle

⇒    AC = [tex]\sqrt{AO^{2}+OC^{2} }[/tex] = [tex]\sqrt{4^{2}+(-4)^{2} }[/tex] = [tex]\sqrt{32}[/tex] = 4√2 units.

and AB = [tex]\sqrt{AO^{2}+OB^{2} }[/tex] = [tex]\sqrt{4^{2}+2^{2} }[/tex] = [tex]\sqrt{20}[/tex] =2√5 units.

Circumference of ΔAOC = AC+CO+AO = 4√2+4+4 =4√2+8 = 4√2(1+√2) units.

Circumference of ΔAOB = AB+BO+AO = 2√5+2+4 =2√5+6=  2(√5+3)units.

Circumference of ΔABC = AB+BC+AC = 2√5+6+4√2 = 2(3+√5+2√2)units.

Therefore, circumference of ΔAOC, ΔAOB and ΔABC are  4√2(1+√2), 2(√5+3) and 2(3+√5+2√2) units respectively and area of ΔAOC, ΔAOB and ΔABC are 8,4 and 12 square units respectively.

If Giuseppe’s buys supplies to make pizzas for $4. Operating expenses of the business are 110% of the cost and the profit made is 130% of cost. the regular selling price of each pizza is: $13.60.

Using this formula to find the regular selling price

Regular selling price = Cost price × (Operating expenses + Profit +1)

Where:

Cost price =$4

Operating expenses = 110% or 1.1

Profit = 130% or 1.3

Let plug in the formula

Regular selling price =$4 × (1.1 +1.3 +1)

Regular selling price  =$4 × 3.4

Regular selling price  = $13.60

Therefore the regular selling price is $13.60.

The cost for 1 hot dog is $2.25  and the cost for 1 bag of potato chips is  $1.5   .

In the question ,

it is given that ,

a vendor is selling  hot dogs and bags of potato chips ,

the customer bought 5 hot dogs and 4 bags of potato chips for $17.25

let the cost of 1 hot dog = h    and

let the cost of 1 bag of potato chips = p

So , the equation is 5h + 4p = 17.25

and another customer buys , 2 hot dogs and 2 bags of chips

So , the equation is , 2h + 2p = 7.50

2p = 7.50 - 2h

and 4p = 15 - 4h

Substituting 4p = 15 - 4h in the equation 5h + 4p = 17.25 , we get

5h + 15 - 4h = 17.25

h + 15 = 17.25

h = 17.25 - 15

h = 2.25

and 4p = 15 - 4h

4p = 15 - 4(2.25)

4p = 15 - 9

4p = 6

p = 6/4

p = 1.5

The period used = 4 years, Rate used = 6%, the PV factor used = 0.792, and the PV of the amount desired at end of the period = $7049.63.

According to the given question, the required solution would be as:

The period used = 4 years,

Rate Used = 6%

We know that,

PV factor = 1/(1+r)ⁿ

Here r = 6% = 6/100 = 0.06, and n = 4

PV factor = 1/(1+0.06)⁴

PV factor = 1/(1.06)⁴

PV factor = 0.792

PV of the amount desired at end of the period = FV/(1+r)ⁿ

Here FV = $8,900.00

PV of the amount desired at end of the period = 8,900.00/(1+0.06)⁴

PV of the amount desired at end of the period = 8,900.00/(1.06)⁴

PV of the amount desired at end of the period = $7049.63

According to a common understanding, capitalism is an economic system in which individual actors own and control property according to their interests and where supply and demand freely set market prices in a way that benefits society. The fundamental quality of capitalism is the desire to make a profit.

Capital, which developed from capitale, a late Latin term based on caput, meaning "head," is where the word "capitalism" originates. Chattel and cattle, both of which allude to moveable property, also have their roots in capital (only much later to refer only to livestock).

The annual percentage yield (APY) of Rocio is 3.11 %

What is Annual Percentage Yield?

The annual percentage yield (APY) is the real rate of return earned on an investment, taking into account the effect of compounding interest.

Given data ,

Deposit amount of Russ = $ 3200

Interest rate R = 3.1 %

And it is given that the interest rate is compounded daily , so

Interest rate R = 3.1 % / 365

                       = 0.031 / 365

                       = 0.000084

Now , The annual percentage yield (APY) is calculated as

The interest amount = 3200 x ( 1 + 0.000084 )³⁶⁵

                                 = 3200 x ( 1.000084 )³⁶⁵

                                 = 3200 x 1.031133

                                 = 3299.6272

                                 ≈ 3299.627

Therefore , the interest will be

= 3299.627 - 3200

= $ 99.627

Now , the annual percentage yield (APY) is given by

= Interest / Deposit

= 99.627 / 3200

Answer: $54,742.75

Step-by-step explanation:

Each year you need to multiply the employee's current salary by 4% (in decimal form this is 0.04). Then you add the result to their current salary.

Year 1

40000 * 0.04 = 1600

40000 + 1600 = 41600

Year 2

41600 * 0.04 = 1664

41600+ 1664 = 43264

Year 3

43264 * 0.04 = 1730.56

43264+ 1730.56 = 44994.56

Year 4

44994.56 * 0.04 = 1799.78

44994.56+ 1799.78 = 46794.34

Year 5

46794.34 * 0.04 = 1871.77

46794.34+ 1871.77 = 48666.11

Year 6

48666.11 * 0.04 = 1946.64

48666.11+ 1946.64 = 50612.75

Year 7

50612.75 * 0.04 = 2024.51

50612.75+ 2024.51 = 52637.26

Year 8

What is the slope of line?

Given two line-side coordinates, use the slope formula to determine the slope of the line. The slope is defined as the ratio of the change in the y values to the change in the x values using the formula m=(y2-y1)/(x2-x1). x1 and y1 are represented by the first point's coordinates. The second points are located at x2, y2, and their locations. Whichever point you choose to classify as the first and which as the second doesn't matter.

For the first point, we would have 9=3k;

So we have k=9/3.

For the second point, we would have 13=4k;

this would mean that k=13/4.

And for 3rd point, we would have 23 =7k;

Checking using proportions shows us that 11/7 does not equal 13/4:

Step-by-step explanation:

The angle θ = 170° and  θ = 350°  have the same Sine and Cosine as 10° respectively

Since the Sine and Cosine of angle 10° are positive

In order to find an angle θ with 0° < θ < 360° that has the same Sine and

Cosine as 10°, we have to check the quadrants in Trigonometry where Sine and Cosine are positive

1st quadrant (0° - 90°) => Sine is positive (10° is here)

2nd quadrant (91° - 180°) => Sine is positive

3rd quadrant (181° - 270°) => None is postive

4th quadrant (271° - 360°) => Cosine is positive

We will consider the 2nd and 4th quadrants:

2nd quadrant: Sine 10° = Sine (180 - 10)° = Sine 170°

4th quadrant: Cosine 10° = Cosine (360 - 10)° = Cosine 350°

2) In second circle radius is 46 inch and diameter is 92 inch

3)In third circle radius is 23 ft and diameter is 46ft

What's the radius solution?

The radius formula is easily obtained by halving the circle's diameter. The line segment created when we join a point on a circle's circumference to its exact center is referred to as the ring's radius. The radius of a circle is the separation between its center and circumference.

What is diameter, for instance?

If you look at the cycle wheel, the spikes that run through the center from one end to the other are an illustration of diameter. This is comparable to the diameter of a circle, which is the line segment that extends from one end of the circle to the other end while passing through the center of the circle.
