Answer: Amount of Money Barak  earned last week =$125

Step-by-step explanation:

Amount of money Barak spent= $20

Amount of money spent = 16% of Money earned (X)can be represented as

16%  x  X =20

0.16 x X  =20

X = Money earned last week = 20/ 0.16= $125

Answer:

43.98 (44) Circumference

Area: 153.94 (154)

Step-by-step explanation:

Answer:

Circumference: 14π square inches or approximately 43.96 square inches

Area: 49π square inches or 153.86 square inches

Step-by-step explanation:

Circumference = 2πr, where r = radius

2π(7) = 14π or 14(3.14) = 43.96

Area = πr^2, where r = radius

π7^2 = 49π or 49(3.14) = 153.86

The answer is below

Step-by-step explanation:

A composite function is a function which is placed inside another function, this type of function can be calculated by substituting one function into another function.

If two functions g(x) and f(x) are inverses, then each will reverse the effect of the other. That is, (f○g)(x)=f(g(x))=x and (g○f)(x)=g(f(x))=x.

Given that F(x) =(x+4)/3 and g(x) = 3x – 4

a) (f o g)(x) = f[g(x)]

   = f(3x - 4)

   = [(3x - 4) + 4]/3

   = [3x - 4 + 4]/3

   = 3x / 3

   = 3

b) (g o f)(x) = g[f(x)]

   = g[(x + 4)/3]

   = 3(x + 4)/3 - 4

   = x + 4 - 4

   = x

We can see that (f o g)(x) = (g o f)(x) = x. Hence the functions are inverse functions.

Answer:

1.-6 is the Y intercept

2.3/14

3.empty set

step by step explanation:

1.Y= mX-B

so B is -6

2.11-2raised3/14

2raised 3 is 8

that means 11-8/14=3/14

3. 7(x+3)= 7x-8

7x+21=7x-8

7x-7x=-8-21

0=-29

Step-by-step explanation:

Answer:

77 5/8

Step-by-step explanation:

a) Multiply the whole number 6 by the denominator 4. Whole number 6 equally 6 * 4/4

= 24/4

b) Add the answer from the previous step 24 to the numerator 3. New numerator is 24 + 3 = 27

c) Write a previous answer (new numerator 27) over the denominator 4.

Conversion a decimal number to a fraction: -11.5 = -115/10

= -23/2

a) Write down the decimal -11.5 divided by 1: -11.5 = -11.5/1

b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)

-11.5/1

= -115/10

c) Simplify and reduce the fraction

-115/10

= -23 * 5/2*5

= -23 * 5/2*5

= -23/2

Multiple: 27/4

* (-11.5) = 27 · (-23)/4 times5

= -621/8

Answer:

135

Step-by-step explanation:

Ratio = 3 : 9

Angles are : 3x , 9x

3x + 9x = 180         {supplementary angles}

   12x   = 180  {divide both side by 12}

       x = 180/12

x = 15

Larger angle = 9x = 9*15 = 135

If the distance across the floor from one mark to the other is [15] inches then the [Pythagorean Theorem] says that because 12^2+9^2=[15]^2, a right triangle is formed.

Answer:

The answer is below

Step-by-step explanation:

A triangular prism is a polyhedron (three dimensional shape) made up of two equal triangles, two equal rectangle and a base rectangle.

The total surface are of a triangular prism is given as:

A = bh + 2ls + lb

where b is the base of the triangle, h is the height of the triangle, l is the length of the base rectangle and s is the length of the slant side of the triangle.

Given that:

b = 6 ft, s = 5.5 ft, h = 5 ft, l = 9 ft.

Therefore:

A = (6 * 5) + 2(9 * 5.5) + (9 * 6) = 183 ft²

Therefore 183 ft² of fabric is needed to make the tent

Answer:

So Imma use the explanation area to answer this (I'll link a video on how I solved this.)

Step-by-step explanation:

F(x)=1/3(-5x -4)³-3 (Multiply 1/3 by -5x & -4. Be sure to move the unused parts of the equation down)

F(x)= -1.66x -1.33³-3 (Here we need to use our exponent)

F(x)= -1.66x -2.37 -3 (Here we need to subtract -3 from -2.37)

F(x)= -1.66x - 0.629 (You need to subtract 0.629 from the right side and left side)

-0.629 =  -1.66x (Now since X is attached by multiplication, we need to divide both sides by -1.66)

0.378 = x (this means that your inverse is 0.378)

Answer:

Interés compuesto:

El tiempo entre dos fechas en las que los intereses se agregan al capital se llama periodo

de capitalización, y el número de veces por año en que los intereses se capitalizan se llama

frecuencia de conversión y de denota con la “p”.

A la frecuencia de conversión se le conoce también como frecuencia de capitalización de

intereses.

P = 1 Para periodos anuales, los intereses se capitalizan cada año.

P = 2 Si los periodos son semestrales

P = 3 Para periodos cuatrimestrales.

P = 4 Para periodos trimestrales.

P = 6 Cuando son periodos bimestrales

P = 12 Para periodos de un mes.

P = 13 Si los periodos son de 28 días.

P = 24 Para periodos quincenales

P = 52 Para periodos semanales

P = 360 0 365 Si son periodos diarios.

M = Ceit

M = C(1 + i / p)tp

Donde:

t = periodo en años

tp = es el número de periodos

i = La tasa de interés anualizada en “p” periodos por año.

Ejemplo: Inversión de un capital para monto preestablecido. (Villalobos, 2007, pág. 171)

a) ¿Qué capital debe invertirse ahora al 12.69% anual capitalizable por bimestre para tener

$40,000 en 10 meses?

b) ¿A cuánto ascienden los intereses?

Datos:

El plazo “t” debe estar en años, por lo que para expresar 10 meses en estas unidades se divide

entre 12, o sea, el número de meses que tiene un año. En consecuencia, el plazo en años es t =

10 / 12. La frecuencia de conversión o capitalización de intereses es p = 6 porque 6 son los

bimestres que tiene un año. Entonces:

tp = (10/12)6 = 5 bimestres.

El monto es M = $40,000, la tasa de interés es i = 0.1269 o 12.69% anual, capitalizable por

semestres, y la incógnita es C, la cual se despeja de la igualdad que resultó de sustituir estos

valores en la ecuación:

Solución:

Fórmula: M = C(1 + i/p)tp

40,000 = C(1 + (0.1269 / 6))5

Apuntes de Matemáticas Financieras Prof. Gerardo Gutiérrez Jiménez

40

40,000 = C(1.02115)5

40,000 = C(1.110318838)

C = 40,000 / 1.110318838

C = $36,025.68797

Solución b) Los intereses son la diferencia entre el monto y el capital:

I = M – C

I = 40,000 – 36,025.69

I = $3,974.31

Ejemplo: Monto que se acumula al invertir un capital.

El capital es C = $65,000, la tasa anual es i = 0.10, la frecuencia de conversión es p = 2 por que

el año tiene dos semestres, t = 3 porque el capital se acumula tres años, el número de periodos

en el plazo es tp = 6, entonces el monto según el teorema es: (Villalobos, 2007, págs. 170-171)

R = $87,106.22

Ejemplo: Tasa de interés para duplicar un capital.

¿Con qué tasa de interés anual capitalizable por bimestres se duplica un capital en 3 años?

(Villalobos, 2007, pág. 172)

R = 23.55%

Ejemplo: Valor presente de un crédito e intereses.

El 25% del precio de un mueble de sala se paga con un documento con valor nominal de $4,000

y vencimiento a 30 días. Un 30% se liquida mediante un pago a 60 días de plazo, otro 30% con

un documento a 90 días de la compra y el 15% restante se dejan como anticipo. Obtenga:

a) El precio del mueble.

b) El anticipo y los otros dos pagos.

c) El cargo total por intereses.

Suponga que la mueblería carga el 22.20% anual compuesto por mes en sus ventas a crédito.

(Villalobos, 2007, págs. 173-174)

Solución inciso a:

C1 = $3,927.344134

Entonces:

Precio = $15,709.38

Solución del inciso b: “el anticipo es el 15% de este precio”.

C2 = 4,712.81

Entonces, el segundo pago es el valor futuro de este capital, es decir:  

Apuntes de Matemáticas Financieras Prof. Gerardo Gutiérrez Jiménez

M2 = $4,888.80

El valor presente del último pago es igual al del anterior y por tanto, este pago es:

M3 = $4,979.24

Finalmente, solución del inciso c), Los intereses son la diferencia entre el total pagado y el precio

del mueble:

I = $512.07

Note que la tasa de interés global es:

G = 3.2787%
