This is exponential decay which can be expressed as:
y=ab^t, y=final value, a=initial value, b=rate, t=time
In this case a=25000, r=(100-20)/100=0.8 so
y=25000(0.8^t), so in 4.5 years...
y=25000(0.8^4.5)
y≈$9158.93 (to nearest cent)
Answer:
Positive-Real
Zero-Complex
Negative-Real
Really hope this is right
Since Juanuary has 31 days we will also count the 31st day.Lets count the days Kevin waters his ivy.He will water it every 3 days so let’s count by threes.
2 5 8 11 14 17 20 23 26 29
That is all theaters you.Can have in February if you count by 3s.
He will water his cactus every 5th day.Just like before let’s count but this time by 5s.
4 9 14 19 24 29
There are two dates Kevin will water both plants but you said to do the first one so the date will be 14.
Your Answer is the 14th
Answer:
b = 
Step-by-step explanation:
To clear the radicals square both sides
= 
( cross- multiply )
(6 - a)(8 + b) = b - 7 ← expand factors on left using FOIL
48 + 6b - 8a - ab = b - 7 ( subtract 48 from both sides )
6b - 8a - ab = b - 55 ( add 8a to both sides )
6b - ab = b - 55 + 8a ( subtract b from both sides )
6b - ab - b = 8a - 55, that is
5b - ab = 8a - 55 ← factor out b from each term on the left side )
b(5 - a) = 8a - 55 ← divide both sides by (5 - a)
b =
