Answer: Part A: y= -1200x +25000 this is because it decreases 1200$ a year that is your rate of change and it started at 25000 that is your y-intercept
Part B: question a would be 46000$ because that’s where the zero is which is when he bought it question b is 3000$ because that is how much the table decreases with each year
Step-by-step explanation:
Circumference is <span>πd</span> where d is the diameter. You can derive this to isolate diameter by dividing both sides by π.
<span>D=<span>Cπ</span></span>. Now just plug the numbers for your variables.
<span>D=<span>75.363.14</span></span>
<span>D=24</span>
The diameter is 24 yards.

Answer:
-- Exponential decay
-- Exponential growth
-- Exponential growth
-- -- Exponential growth
-- -- Exponential growth
-- Exponential decay
Step-by-step explanation:
The equations are:
An exponential equation is of the form
Where
If , then it is a growth
If , then it is a decay
If , then it is none.

Put 3 where x is, then do the arithmetic.
... 3 - 7·3 + 2·3
... = 3 - 21 + 6
... = -18 + 6
... = -12
_____
If you like, you can simplify first.
... = 3 + x(-7 +2)
... = 3 -5x
For x=3, this is
... = 3 -5·3
... = 3 -15
... = -12
