Exponential equation is
y=a(b)ˣ
when b>1, it is growth
when 0>b>1, it is decay
so
we want the 2nd number to be more than 1
that would be the 3rd one, y=3(8)ˣ
Answer:
A) There is a pretty strong positive linear relationship between sales of firewood and cough drops.
Explanation:
Correlation coefficient: It is used to analyze the relationship between two variables, the greater it is the stronger the relationship will be.

2x - 24 = x - 2
2x - x = -2 + 24
x = 22
BC = x = 22
Answer:
x = 18.
Step-by-step explanation:
The 2 amgles are adjacent so add up to 180 degrees so we have:
x^2 - 11x + 3x = 180
x^2 - 8x - 180 = 0
(x -18)(x + 10) = 0
x = -10, 18.
x = -10 cannot be correct because that would make the 3x angle = -30.
Answer:
about $62.18
Step-by-step explanation:
Just find the amount of the percentage so,
7.5% of 829 = 62.175
So the tax for the phone is 62.175,
Now round it to the nearest tenth since you can't pay 62.175 because you can't pay half a cent.
62.175 = about $62.18
