Answer:
Step-by-step explanation:
If x - 1 is a factor of the cubic, then 1 should result in 0 when you put it in the cubic for x. Does it?
f(1) = 2(1)^3 - 15(1)^2 + 22(1) + 15
f(1) = 2 - 15 + 22 + 15
f(1)= 24.
No the result is not zero. So x - 1 is not a factor.
However there must be something that makes this cubic go to zero. The easiest way to find it is to graph it.
The numbers that do make this zero are -0.5, 3, 5
Which mean that the factors are (2x+1)(x-3)(x - 5)

_______
4^2 h^4
when you have negatives, you want them to be positive. To do that you need to convert it into a fraction

Answer:
Step-by-step explanation:
Ok so to find constant of proportionality, you need to find K.
X would be gallons and y is cost.
To find k you need to do k=y/x
k=17.50/5
k=3.5
That's the first one. Now you need to make sure its <em>constant</em> with each one so keep going.
k=35/10
k=3.5
k=52.50/15
k=3.5
For all of those 3.5 was constant.
Because they are constant, that means the data in the graph is a proportion.
An example of an unproportional relationship would be if instead of 15 in the last column, it was 16.
k=52.50/16
k=3.28
That be different from the other 3.5's meaning its not proportional. But that's just an example.

Answer:
Kayla = 0.4 inches
Miranda = 0.46 inches
Stefano = 0.5 inches
Kateira = 0.58 inches
Step-by-step explanation:
Kateira plant = 0.58 inches
Stefano plant = 1/2 inch
Change to decimal
Stefano plant = 0.5 inches
Kayla plant = 0.4 inches
Miranda plant = 5/11 inches
Change to decimal
Miranda plant = 0.46 inches
Order from least to greatest
= 0.4, 0.46, 0.5, 0.58 inches
That is, Kayla, Miranda, Stefano and Kateira respectively
