The modeling with mathematical expressions allow to make predictions about the thing being modeled. For example, we can predict if the population of the country will decrease or increase. What velocity has to have the spaceship to get to the other planet. How long it takes travel from on city to another by plane and by car. How many schools should be build during next 10 years.
Answer:
<h2>a = 11</h2>
Step-by-step explanation:
Since 2.5% as a decimal is .025, the equation to get this is:
(.025)(80000)
Once multiplied, these equal 2,000. Or in other words, the Smiths pay $2,000 in school taxes per year.
No because when one number is odd and the other one is even it can't be simplified (unless they are multiples/factors of each other) ex: 7/14
Answer:
an = 4/3n - 13/3.
Step-by-step explanation:
The first term is a1,
a24 = a1 + 23d
83/3 = a1 + 4/3* 23
a1 = 83/3 - 92/3
a1 = -9/3 = -3.
So the nth term an = -3 + 4/3(n - 1)
an = -3 + 4/3 n - 4/3
an = 4/3n - 13/3
