Answer:
The cost in 2015 will be $283.45.
What is the reference point (t=0)?
d. The year 2005.
Step-by-step explanation:
The exponential growth model for the cost is the following:
In which C(t) is the cost after t years, 
is the initial cost and r is the decimal inflation rate
In this problem, we have that:
What will it cost in 2015 assuming the rate of inflation remains constant?
2015 is 10 years after 2005, so this is C(10).
The cost in 2015 will be $283.45.
The reference point is the year in which t = 0, so the year 2005.
16x can be broken down into factors of -105.
21 and -5 come to mind.
7x² + 21x - 5x - 15
7x(x + 3) - 5(x + 3)
(7x - 5)(x + 3) is the factorised form.
Answer:
D = rt
b, slower plane
8.5(3b) - 8.5(b) = 1649
25.5b - 8.5b = 1649
17b = 1649
b = 97mph
3b = 291mph
Answer:
−5 < x < 10
Step-by-step explanation:
Add 1 to each part of the three parts of the inequality:
-6 +1 < x - 1 +1 < 9 +1
-5 < x < 10 . . . . . simplify
_____
The only place where there's an x is in the middle section. The only operation performed on x is subtraction of 1. To undo that subtraction, you add 1, but you must add 1 to all sides of the comparison symbols in order to keep them true.
Such a compound inequality is the same as the two inequalities:
Solving either one of these is done by adding 1 to both sides of the < symbol:
You can put these back together in the form of the compound inequality ...
-5 < x < 10
Answer: All assets represent money, but only liquid assets can be easily turned into spendable money.
Earned income is money you received for a job performed and capital gains are profits from investments.
Step-by-step explanation: Because this is the definition of liquid assets: A liquid asset is cash on hand or an asset that can be readily converted to cash. An asset that can readily be converted into cash is similar to cash itself because the asset can be sold with little impact on its value.
-Earned income refers to salary, bonuses, commissions, tips that you receive because of a job that you have done from an employer or your business.
-Capital gains refer to money that you receive because of the sale of a capital asset like stocks or real estate.
