Answers

Answer:

a. y= -1221x+19820

b. For every year the car value decreases $1,221.

c. $11,273

Step-by-step explanation:

a. (y2-y1)/ (x2-x1)

(16157-17378)/(3-2)= -1221

For the y-intercept you would just add 1221 twice to the value of the 2 year old car, get the value of 0 years.

Times are tough for Peter the Penguin and his "Hug a Penguin" business has been on the decline. Last year Peter the Penguin made $570 dollars from selling hugs. If he experienced a 20% decrease in sales how much did he make this year?

Answers

Answer:

the new sales after decrease in sales percentage this year is $456 dollars

Step-by-step explanation:

The computation of the sales made this year is  shown below:

Given that

last year sales would be $570 dollars

And in this year there is 20% decrease in sales

so, the new sales after 20% decrease would be

= Last year sales × (1 - decreased percentage)

= $570 × (1 - 0.20)

= $570 × 0.80

= $456 dollars

hence, the new sales after decrease in sales percentage this year is $456 dollars

In ARST, mZR = (5x – 11)", mZS = (3x – 3)°, and m_T = (3x + 18)º.
Find mZR.

Answers

Answer:

m∠R = 69

Step-by-step explanation:

m∠R + m∠S + m∠T = 180       {Angle sum property of triangle}

5x - 11 + 3x - 3 +  3x + 18 = 180

5x + 3x + 3x - 11 - 3 + 18 = 180     {Combine like terms}

                     11x  +4      = 180

                                 11x = 180 - 4

                                 11x = 176

                                    x = 176/11

x = 16

m∠R = 5x - 11

        = 5*16 - 11

        = 80 - 11

m∠R = 69

19. Perimeter of rectangle = 2(l + b)

l = 25m

b = 16m

Perimeter of rectangular park = 2 (25 + 16)

= 50 + 32

= 82m

Perimeter of square park = 82m

(given that, perimeter of rectangular and square park are equal)

Perimeter of square = 4a

4a = 82

a = 82/4

a = 20.5m

Area of square park = a²

= 20.5²

6. A farmer sows a certain crop. It costs $240,000 to buy the seed, prepare the ground, and sow the crop. In one year's time it will cost $93,200 to harvest the crop. If the crop will be worth $350,000, and the interest rate is 7%, what is the net present value (NPV) of this investment?

Answers

Answer:

$0

Step-by-step explanation:

Given that:

Preparation and sowing cost = $240,000

Cost of harvest after a year = $93,200

Worth of crop = $350,000

Interest rate (r) = 7% = 0.07

Net present value of Investment :

[(worth - Cost after 1 year) / (1 + r)] - initial investment cost

[(350,000 - 93,200) ÷ (1 + 0.07)] - 240,000

[256,800 / 1.07] - 240,000

$240,000 - $240,000

= $0

Una persona ahora en el banco 1000 pesos, el cual le ofrece un interés fijo de 3%. La función que relaciona el dinero ahorrado que recibirá después de x meses de ahorro

Answers

Answer:

Interes= [Principal*(1+tasa de interes)^x] - Principal

Step-by-step explanation:

Dada la siguiente información:

Principal= $1,000

Tasa de interes= 3% anual = (0.03/12)= 0.0025 mensual

Número de periodos= x

Para calcular el interés ganado, hay que usa la formula siguiente:

Interes= [Principal*(1+tasa de interes)^x] - Principal

Por ejemplo, para 6 meses:

Interes= [1,000*(1.0025^6)] - 1,000

Interes= $15.09
