F ( x ) = 7 x + 2
y = 7 x + 2
- 7 x = - y + 2  /*(-1)
7 x = y - 2   / : 7
x = y/7 - 2/7 = ( y - 2 ) / 7
The inverse of the function is:
f^(-1) ( x ) = ( x - 2 ) /7

Effectus [21]

The correct answer is:

X=2

Y=4

Here's how you solve it!

log5\sqrt{5}( 125)= x

Write in exponential form.

log_{5} \frac{3}{2} 125=x

log_{5} \frac{3}{2} (5^{3} )=x

Simplify.

x=2

log_{2\sqrt{2} 64= y

Write in exponential form

log_{2}\frac{3}{2}  (2x^{6} )= y

Simplify.

y=4

Hope this helps! :3

P(<em>Z</em> ≥ <em>z</em>) = 1 - P(<em>Z</em> ≤ <em>z</em>) = 0.06

==>   P(<em>Z</em> ≤ <em>z</em>) = 0.94

Una empresa comercial vende automóviles cuyo precio es de S/. 60 000, con una cuota inicial del 20%, para cancelar el saldo en 3
Inessa05 [86]

Responder:

2560

Explicación paso a paso:

Dado lo siguiente:

Precio del automóvil = 60000

Cuota inicial = 20% del precio = (0.2 * 60000 = 12,000

Saldo = (60000 - 12000) = 48000

La empresa cobra un interés simple del 12% cada 6 meses

Periodo de pago = 30 meses / 6 = 5 periodos

Interés simple: p * r * t

= 48000 * 0,12 * 5 = 28800

Por lo tanto, monto total a reembolsar, incluidos los intereses:

Balance + 28800; 48000 + 28800 = 76800

El reembolso mensual es fijo;

Por lo tanto,

76800/30 = 2560
