.Margaret is treating her best friend to a birthday dinner. Before ordering, Margaret wants to have an idea of the final bill. T
Nikitich [7]

Answer:

Your answer is 61.

Step-by-step explanation:

Simple enough! We simply round up each cost to the nearest whole dollar. $6.50 can be rounded to $7, $15.75 can be rounded up to $16, $2.25 can be rounded up to $3 (Note we're rounding up, in normal rounding we would round down to $2). Finally, $7.25 can be rounded up to $8.

Next comes simple algebra,

7+(16*2)+(3*2)+(8*2)=61

Therfore, your overestimate of the cost would be 61.

Assume that f is continuous on [-4,4] and differentiable on (-4,4). The table gives some values of f'(x) x: -4, -3, -2, -1, 0, 1
kondaur [170]
f will be increasing on the intervals where f'(x)>0 and decreasing wherever f'(x). Local extrema occur when f'(x)=0 and the sign of f'(x) changes to either side of that point.

f'(x) is positive when x is between -4 and some number between -2 and -1, and also 2 (exclusive) and 4, so you can estimate that f(x) is increasing on the intervals [-4, -2] and (2, 4].

f'(x) is negative when x is between some number between -2 and -1, up to some number less than 2. So f(x) is decreasing on the interval [-1, 1].

You then have two possible cases for extrema occurring. The sign of f'(x) changes for some x between -2 and -1, and again to either side of x=2.
