Which statement is true about the local minimum of the graphed function?
a over the interval [–4, –2], the local minimum is 0.
b over the interval [–2, –1], the local minimum is 25.
c over the interval [–1, 4], the local minimum is 0.
d over the interval [4, 7], the local minimum is -7.

554.4

step-by-step explanation:

44*12.6=544.4

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
