Jeremy can determine the total number of miles walked at a constant speed by using the formula an=an-1+3. If a1=2, what are the
KengaRu [80]
If the recursive formula is a(n)=a(n-1)+3 and a1=2 then the explicit formula is:

a(n)=2+3(n-1) which simplifies to

a(n)=2+3n-3

a(n)=3n-1 so the first three terms are a(1), a(2), and a(3) which are:

What’s a larger number is two less than four times a smaller. if the sum of the number is 18
s344n2d4d5 [400]
Let x be the larger number and y be the smaller number.
Using the given info, we get
x = 4y - 2
We also know that 
x + y = 18
Substitute x = 4y -2 into x + y = 18
(4y -2) +y = 18
5y - 2 = 18
5y = 20
y = 4
Enter this value into x = 4y - 2
x = 4(4) - 2
x = 14
The larger number is 14 and the smaller one is 4.

Suppose that the population of a certain town, in thousands, was 105 in 1990 and 141 in 2002. Assume that the population growth
ASHA 777 [7]
Let's calculate the growth rate from 1992 to 2002 (Since it's assumed to be a LINEAR function, instead of an exponential one)

Growth rate = (141 - 105 )/ (105) = 12/35

Growth Rate = Slope, then y = ax becomes y = (12/35).x OR y =0.342x

Why is it important to be aware of marketing tricks?
ddd [48]
Because people in the market can use it against you / scam you.
If you know someone doesn't have any prior knowledge of what you're selling you can easily say," this helped my grandma cure her cancer" etc. You could easily be used if you're not aware.

(20 points) please give me motivation to study and study tips or test taking tips for finals. it would be greatly appreciated.
Daniel [21]

Answer: Think about graduating. Think about never having to take the courses again. You're almost at the finish line! It'll be worth it. You've worked hard all year for this. You can do it!

Study tips: I would recommend Quizlet! They have a section that generates study games. It's a lot more fun than normal studying. It's also a good idea to make a goal for yourself. Try to make a challenge of achieving a certain score! By the time you accomplish said score, you'll find that you've learned a lot. Another tip is to make sure you take breaks. If you work too long without giving yourself a break, it will become harder to focus and your brain will become tired. Just don't get too distracted! set yourself an alarm during break times to help you stay on task. If you become frustrated with a certain subject or task, take a break from that task. Use this time as an opportunity to work on another subject. You can begin working on the first subject again once you feel refreshed. A lot of this may sound redundant, but hopefully it will help at least a little bit. Good luck!
