In 2012, the number of people attending the south coast comic convention was 5,000. the number of attendees continues to grow at a rate of 8.7% each year. if t is the number of years after 2012, write the equation in simplest form that could be used to determine how long it will take the number of attendees to reach 11,000.

Answer from: hosain5801

11000=5000(1.087)^t

Explanation:

The exponential growth function is given by :-

f(x)=A(1+r)^t , where A is the initial value , r is rate of growth and t is the time period.

Given: The initial population of attendees (in 2012) =5,000

The rate of growth = 8.7 %=0.087

If t is the number of years after 2012 , then the exponential growth function that models the given situation will be :-

$f(x)=5000(1+0.087)^t\\\\\Righatrrow\ f(x)=5000(1.087)^t$

Now, the equation that could be used to determine how long it will take the number of attendees to reach 11,000 will be :-

11000=5000(1.087)^t

Answer from: Quest

assuming that your periodic table has eighteen columns, you should highlight the four elements in the third column from the left of the table.

explanation

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the $3d$ have energy higher than those in the $4 s$ orbital while lower than those of the $4 p$ orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the $4s$ orbital is therefore filled right after $3p$ orbitals and before $3 d$ orbitals.

potassium has electron configuration $[\text{ar}] 4 s^{1}$ and calcium $[\text{ar}] 4 s^{2}$ . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration $[\text{ar}] 4 s^{2} \; 3d^{1}$ and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the $ns^{2} \; (n-1) p^{1}$ and should be highlighted as well.
