Answer:
Z= 5ft
Step-by-step explanation:
14/7 is equal to 2 so I divided 10/2 to get 5.
The situation above is an arithmetic sequence with the third term (a3) equal to $285 and sixth term (a6) equal to $510. To determine the nth term of the arithmetic sequence, use the equation,
an = a1 + (n - 1)d
where a1 is the first term and d is the common difference. To solve for these, use the given values,
285 = a1 + (3-1)(d)
510 = a1 + (5 -1)(d)
Solving for the unknowns gives an answer of a1 = 60 and d = 112.5.Thus, the equation is,
y = 60 + 112.5x
Using it's critical points, it is found that the least possible degree of the polynomial graphed above is 4.
<h3>What are the critical points of a function?</h3>
The critical points of a function are the values of x for which:
At these critical points, the behavior of the function changes from increasing to decreasing or vice versa.
If a function has n critical points, the least possible degree is of n + 1.
From the changes in behavior of the graph, the function has critical points at:
- .
The function has 3 critical points, hence the least possible degree of the polynomial graphed above is 4.
