Help please And how would you get the answer need asap

No the 2 equations are not equal
the -1/10, -1/10 can't be subtracted from 1 3/10g
they are not like terms
the proper equation is
1/5g converts to 2/10g
2/10g - 1g + 1 3/10 g = 5/10g or 1/2g
1/2g - 2/10 is final equation

The population p (in millions) of Italy from 1990 through 2008 can be approximated by the model p=56.8e^o.oo15t , where t repres

dimulka [17.4K]

As we already have the model that describes the change of the population in Italy in terms of the years that have elapsed, we only have to replace the conditions that are requested in that equation.

Therefore to find the population of Italy in the year 2000 (t = 10 years) substitute t = 10 in the equation and have:

$p = 56.8e^{0.0015*10}\\$

$p=57.6584$ million people

To find the population of Italy in 2008 (t = 18 years)

substitute t = 18 in the equation and have:

$p=56.8e ^{0.0015*18}\\$

$p=58.3545$ million people

To predict the population in Italy for 2015 and 2020 with this model, we substitute in the equation t = 25 and t = 30

t = 25

$p=56.8e^{0.0015*25}$

$p=58.9704$ million people

t = 30

$p=56.8e^{0.0015*30}$

$p=59.4144$ million people

Debbie estimated that a caterpillar was 4.5 cm long. Later, she found its actual length to be 4.8 cm. Find the percent error.

Tamiku [17]

Answer:

Percent error = 6.25%

Step-by-step explanation:

Percentage error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.

Mathematically, it is given by this expression;

$Percent \; error = \frac {experimental \;value - theoretical \; value}{ theoretical \;value} *100$

<u>Given the following data;</u>

Experimental value = 4.5cm

Theoretical value = 4.8cm

<em>Substituting into the equation, we have;</em>

$Percent \; error = \frac {4.8 - 4.5 }{ 4.8} *100$

$Percent \; error = \frac {0.3}{4.8} *100$

$Percent \; error = 0.0625 *100$

Percent error = 6.25%
