Answer:

[tex]x = \frac{3}{4} + \frac{ \sqrt{105} }{4} \: \: , \: \: \: x = \frac{3}{4} - \frac{ \sqrt{105} }{4} \\ [/tex]

Step-by-step explanation:

2x² - 3x - 12 = 0

Using the quadratic formula which is

[tex]x = \frac{ - b \pm\sqrt{ {b}^{2} - 4ac} }{2a} \\ [/tex]

From the question

a = 2 , b = - 3 , c = - 12

So we have

[tex]x = \frac{ - - 3\pm \sqrt{ ({ - 3})^{2} - 4(2)( - 12)} }{2(2)} \\ = \frac{3\pm \sqrt{9 + 96} }{4} \\ = \frac{3\pm \sqrt{105} }{4} \: \: \: \: \: \: [/tex]

Separate the solutions

We have the final answer as

[tex]x = \frac{3}{4} + \frac{ \sqrt{105} }{4} \: \: , \: \: \: x = \frac{3}{4} - \frac{ \sqrt{105} }{4} \\ [/tex]

Answer:

25 days

Step-by-step explanation:

Assuming that the farmer waits for n days to get get the maximum profit.

Given that the total number of cows the farmer has, = 100

Currect weight of one cow = 125 kg.

Weight gain rate for one cow = 3 kg/day

So, weight gained by one cow in n days = 3n kg

Therefore, the weight of one cow after n days [tex]= 125 + 3n \;\;kg \cdots(i)[/tex]

Cost for keeping one cow = $5/day.

Cost for keeping one cow for n days = $ 5n

So, Cost for keeping 100 cows for n days [tex]= \$ 5n \times 100 =\$500n \cdots(ii)[/tex]

Current market price = 25 pesos / kg = 125 cents / kg [ as 1 peso = 5 cents]

The falling rate of market price = 1 cent /day.

Fall in price in n days [tex]= 1\times n = n[/tex] cents.

So, market price after n days [tex]= 125-n cent/kg\cdots(iii)[/tex]

By using equations (i) and (iii),

The selling price of one cow after n days [tex]= (125+3n) \times (125-n)[/tex] cents.

So, the selling price of 100 cows after n days [tex]= (125+3n) \times (125-n)\times 100[/tex] cents.

As 1 $ = 100 cents. so

The selling price of 100 cows after n days [tex]=\$ 5(125+3n) (125-n)\cdots(iv)[/tex].

Now, from equations (ii) and (iv)

Net profit, [tex]P = 5(125+3n) (125-n) - 500n\cdots(v)[/tex]

To get the maximum profit, differentiate the profit function in equation (v) with respect to n and equate it to zero to get the value of n, i.e

[tex]\frac {dP}{dn}=0 \\\\\Rightarrow \frac {d}{dn}(5(125+3n) (125-n) - 500n)=0 \\\\\Rightarrow  5[ (125+3n)(-1)+(125-n)(3)]-500=0 \\\\\Rightarrow 5[ -125-3n+375-3n]-500 =0 \\\\\Rightarrow 5[ -125-3n+375-3n]=500\\\\\Rightarrow 250-6n=500/5=100 \\\\\Rightarrow 6n = 250-100=150 \\\\\Rightarrow n= 150/6 = 25.[/tex]

Hence, the farmer has to wait for 25 days to get the maximum profit.

El granjero puede obtener ganancias máximas en el día 229.

En este problema debemos construir una función de ganancia ([tex]G[/tex]), en pesos, igual a la ganancia neta por venta de la carne de vacuno ([tex]N[/tex]) menos los costes de mantenimiento ([tex]M[/tex]). Cada una de las variables ha de considerar el cambio de los indicadores en función del tiempo, entonces:

Función de ganancia

[tex]G = N - M[/tex] (1)

Función de ganancia neta

[tex]N = (125+3\cdot t)\cdot 100\cdot (5-0.01\cdot t)[/tex] (2)

Función de mantenimiento

[tex]M = 5[/tex] (3)

Al aplicar (2) y (3) en (1) tenemos la siguiente fórmula:

[tex]G = (125 + 3\cdot t) \cdot 100 \cdot (5 - 0.01\cdot t) - 5[/tex]

[tex]G = (125 + 3\cdot t) \cdot (500-t) - 5[/tex]

[tex]G = 62500+1500\cdot t -125\cdot t -3\cdot t^{2}-5[/tex]

[tex]G = -3\cdot t^{2}+1375\cdot t +62495[/tex]

El día correspondiente a la máxima ganancia es el valor [tex]t[/tex] del vértice de la parábola. Una forma rápida es mediante herramientas gráficas. Aquí encontramos que el granjero puede obtener ganancias máximas en el día 229.

Answer:

f(g(2))=7

Step-by-step explanation:

The Composite Function

Given f(x) and g(x) as real functions, the composite function [tex](f\circ g)(x)[/tex] is defined as:

[tex](f\circ g)(x)=f(g(x))[/tex]

It can be found by substituting g into f.

The given functions are:

[tex]f(x)=4x+3[/tex]

[tex]g(x)=x^2-3[/tex]

It's required to find f( g( 2 ) )

Find g(2):

[tex]g(2)=2^2-3[/tex]

Operating:

[tex]g(2)=4-3 =1[/tex]

g(2)=1

Now find f(1):

[tex]f(1)=4(1)+3[/tex]

[tex]f(1)=4+3 =7[/tex]

Thus:

f( g( 2 ) )=7

Step-by-step explanation:

Maxwell bought $15,000 worth of 52-week T-bills for $14,650

Therefore the rate of return on investment can be calculated as follows

= 15,000-14,650/14,650× 100

= 350/14,650 × 100

= 0.02389 × 100

= 2.39%

Hence the rate of return on this investment is 2.39%

Step-by-step explanation:

Answer:

y = -4x + 50

Step-by-step explanation:

To write the function we'll use y = mx + b, where y is the distance the boat is away from shore, m is how many km/minute the boat moves at, x is how many minutes it's been, and b is how many km away from shore the boat was at the start. We already know the value of b is 50, so we can put that into the equation:

y = mx + 50

To find how many km the boat moves per minute, let's use the given amount of minutes and km (9, 14) and put them into the equation:

14 = m(9) + 50

Now let's solve for m:

14 = 9m + 50

Subtract 50 from both sides to isolate the 9m:

14 - 50 = 9m + 50 - 50

- 36 = 9m

divide both sides by 9 to isolate the m:

-36/9 = 9m/9

-4 = m

The boat moves at -4 km/minute, which is the same thing as saying that  after 1 minute passes, the boat gets 4km closer to the shore. Now we can input this value into the equation and we have our answer:

y = -4x + 50

Answer:

x = 2/5

Step-by-step explanation:

Given:

7 + 5x = 3(y-2)

Rearrange this equation such that x is expressed in terms of y

7 + 5x = 3(y-2)   (expand right side)

7 + 5x = y(3)-2(3)

7 + 5x = 3y-6   (subtract 7 from both sides)

5x = 3y - 6 - 7

5x = 3y - 13

we are given the y-value of the coordinate pair (? , 5)

simply substitute y=5 into the equation above

5x = 3y - 13

5x = 3(5) - 13

5x = 15 - 13

5x = 2   (divide both sides 5)

x = 2/5

(2x - 8) + (x + 17) = 39

3x + 9 = 39

x = 10

AB = 2(10) - 8 = 12

Answer:

The symbols that we will use are:

a > b   (a is larger than b)

a < b   (a is smaller than b)

a ≥ b   (a is larger than or equal to b)

a ≤ b  (a is smaller than or equal to b).

1) if x represents the inches of snow, we have:

"More than 4 inches" means that x must be strictly larger than 4 inches, this can be written as:

x > 4 inches.

2)  "less than 25 inches" means that x must be strictly smaller than 25 inches, this can be written as:

x < 25 inches.

3) If T represents the temperature

"No more than 8°F" means that the temperature can be smaller than 8°F, or equal to 8°F, then we can write this situation with:

T ≤ 8°F

4) "At least 7°F" means that the temperature can be 7°F or more than that, then we can write this situation as:

T ≥ 7°F
