The answer is 54 dollars I believe
28x + 8y + 2 is the simplified version.
The ascending or descending order of a polynomial is
determined by the increasing or decreasing power of variable “x” respectively.
<span>The question is to find about the polynomial in
descending order, so in this case, the 3rd option is correct, i.e.
4x^2 – 3x + 9 or 4x^2 – 3x^1 +9x^0. The power of “x”
decreasing from 2 to 1 and then finally to 0.</span>
Answer:
The diver will hit the water at 1.5 seconds
Step-by-step explanation:
Given

Required (Missing from the question)
When will the diver hit the water?
To do this, we simply solve for t
When the diver hits the water, the height is 0 (at that point)
So, substitute 0 for h in 

Divide both sides by -16




Split
or 
Solve for t
or 
But time (t) can not be negative.
So:

Hence, the diver will hit the water at 1.5 seconds
Yes on day 7, they both have 46 dollars
