Subject: Decision About Selling Custom Flower Bouquets
Date: April 5, 2025
Our shop, which prides itself on selling handmade gifts and cultural items, has
recently received inquiries from customers about the availability of fresh flower
bouquets for special occasions. This has prompted me to consider whether we
should introduce custom flower bouquets in our shop. We need to decide
whether to start offering this new product. There are three options: provide a
complete selection of custom bouquets for events like birthdays and
anniversaries, start small with just a few ready-made flower arrangements, or do
not add flowers.
There are also three possible outcomes. First, we might see high demand, and the
bouquets could sell quickly. Second, we might have medium demand, with a few
sold each week. Third, there might be low demand, and the flowers may not sell
well, possibly going to waste. These outcomes…
Consider the function f(x) = 2x² - 8x + 3 over the interval 0 ≤ x ≤ 9. Complete the following
steps to find the global (absolute) extrema on the interval. Answer exactly. Separate multiple answers
with a comma.
a. Find the derivative of f (x) = 2x² - 8x+3
f'(x)
b. Find any critical point(s) c within the intervl 0 < x < 9. (Enter as reduced fraction as needed)
c. Evaluate the function at the critical point(s). (Enter as reduced fraction as needed. Enter DNE if
none of the critical points are inside the interval)
f(c)
d. Evaluate the function at the endpoints of the interval 0 ≤ x ≤ 9.
f(0)
f(9)
e. Based on the above results, find the global extrema on the interval and where they occur.
The global maximum value is
at a
The global minimum value is
at x
Determine the values and locations of the global (absolute) and local extrema on the graph given.
Assume the domain is a closed interval and the graph represents the entirety of the function.

The plane 1st turns at a bearing of N 73° E, flies for a while, then 2nd turns to intercept the original path and travels for 50 km at a bearing of S 41° E, back to the original path. As stated the plane traveled 50 km in the 2nd leg of the journey getting back to the path. How far did the plane travel in the 1st leg of the journey?arrow_forwardQuestion 6 Aloha Airlines Flight 007 is flying due east but finds it necessary to detour around a group of thundershowers.
