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

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:

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

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.

c. -1221(7) +19820 =$11,273

The average of your 3 quiz grades is 17 points. Two of your quiz grades are 14 points and 19 points. Write and solve an equation to find the score of your third quiz.

Answers

Answer:

The equation would be 14+19+x=51, and the 3rd quiz score would be 18.

Step-by-step explanation:

To get to the average, you have to add all the quiz scores and divide by the number of quizzes. If you work backwards, you can multiply the average by the number of quiz scores, which is 51. Then you subtract the known test scores, and you get your answer.

how to solve 2x^2-11x+12=0

Answers

Answer:

x= 3/2 and 4

Step-by-step explanation:

Use this method to solve;

First get the multiples of 12: -1, -12 -2, -6 -3, -4 (we use negatives, because we need a positive 12, and a negative 11).

Next, set it up like this: (2x - ) (x- ).

Then plug in (2x-3) and (x -4), and use rainbow to double check.

Then take 2x-3=0 and x -4 =0 to get x.

2x-3=0, add 3 to both sides, leaving you with 2x=3, then divide by 2 to get x alone which leaves x= 3/2, could use 1.5 or 1 (1/2) too.

Then do the same with x-4=0, add 4 to both sides leaving x= 4.

Answers are x= 3/2 and 4.

1.Your brother and some of his friends, all under 12 years old, went to the movies. They paid $60 for their tickets. What equation could describe the situation?

2.Another family went to the movies. They bought some child tickets and some adult tickets and spent $96 altogether.
What equation could describe the situation?
How would the equation change if a child’s ticket cost $10?
How would the original equation change if the total price spent on the tickets were $156?

Answers

Answer:

1. 60=12y

60=5*12 y=5

2. a) 96=16x+12y

b) the 12y would be changed to 10y so, 96=16x+10y

c) 156=16x+12y the number of tickets will change if the total price goes up

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

[tex]b^2-4ac>0\cdots(i)[/tex].

The given expression is [tex]x^2-2x+m[/tex].

Here, a=1, b=-2 and c=m.

So, by using equation (i),

[tex](-2)^2-4(1)(m)>0[/tex]

[tex]\Rightarrow 4-4m>0[/tex]

[tex]\Rightarrow 4m<4[/tex]

[tex]\Rightarrow m<4/4[/tex]

[tex]\Rightarrow m<1[/tex].

Hence, the condition for the expression [tex]x^2-2x+m[/tex] to have two different real roots is m<1.

The yield of corn in bushels per acre and the amount of rain in the growing season.

Identify the explanatory variable and the response variable, if possible.

1. Amount of rain is the explanatory variable and yield of corn is the response variable.

2. Bushels per acre is the explanatory variable and amount of rain is the response variable.

3. Yield of corn is the explanatory variable and amount of rain is the response variable.

4. Amount of rain is the explanatory variable and bushels per acre is the response variable.

5. Rain is the explanatory variable and corn is the response variable.

Answers

Answer:

1. Amount of rain is the explanatory variable and yield of corn is the response variable.

Step-by-step explanation:

Explanatory Variable is the causal variable, which effects the other variable.

Response Variable is the resultant variable, which is effected by the other variable.

In this case, amount of rain effects the yield of corn (bushels per acre).

So, Amount of rain being causal effecting variable - is Explanatory Variable. Corn yield, being resultantly effected variable - is Response Variable.
