A limited-edition poster increases in value each year with an initial value of $18. After 1 year and an increase of 15% per year

Andru [333]

Answer:

$y = 18 * 1.15^x$

Step-by-step explanation:

Given

$a = 18$ --- initial

$r =15\%$ -- rate

Value after a year = $20.70

Required

Expression to calculate its value after y years

This is calculated using:

$y = ab^x$

Where

$b=1 +r$

Substitute $r =15\%$ in $b=1 +r$

$b = 1 + 15\%$

$b = 1 + 0.15$

$b = 1.15$

Substitute $b = 1.15$ and $a = 18$ in $y = ab^x$

$y = 18 * 1.15^x$

Se van a unir dos tramos de cadena: uno mide 0.75 m de largo y el otro 15/100 de metro . ¿Cual será la longitud total ya que est

likoan [24]

Step-by-step explanation:

It is given that,

The length of section 1 is 0.75 m and the length of section 2 is 15/100 m. The total length of the section is equal to the sum of section 1 and section 2. So, we will add them as follows :

$l=0.75\ m+\dfrac{15}{100}\ m\\\\\because \dfrac{15}{100}=0.15\\\\l=0.75\ m +0.15\ m\\\\l=0.9\ m$

So, the length of the section is 0.9 m or 9/10 m

Answer:

x=27, y=18

Step-by-step explanation:

Angle CB is 128, which means angle AC is 72. We can confirm angle O is also 72, since the lines are straight. Angle AM is 27, because AN is a right angle. 63+72+27= 162 180-162=18 Angle ND is 18.
