Answer:
(x^3+3x^2+x+1)+(2x^3-2x^2-2x+2)
3x^3 + x^2 - x + 3
I think I simplified it completely. Hope this helps! Good luck! :)
1 gallon consists of 4 quarts.
1 gallon x 30 = 30 gallons
4 quarts x 30 = 120 quarts
Answer: 120 quarts per hour.
Multiply 190 by 0.27 and you should get your answer
The exponential regression that shows the relationship between the number of subcribers in millions (y) since 1990 is y = 4.9(1.37)ˣ
<h3>How to solve an
exponential function?</h3>
Let y represent the amount of subscribers in millions, x years since 1990.
From the table; at point (0, 4.9):
y= abˣ
4.9 = ab⁰
a = 4.9
At point (10, 118.1)
118.1 = 4.9(b)¹⁰
b = 1.37
The exponential regression that shows the relationship between the number of subcribers in millions (y) since 1990 is y = 4.9(1.37)ˣ
