In isosceles ∆ABC the segment BD
(with D ∈
AC
) is the median to the base
AC
. Find BD, if the perimeter of ∆ABC is 50m, and the perimeter of ∆ABD is 40 m
(I need statement and reasoning)

What is the quadric regression equation that fits these data

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?

What is the common difference for this arithmetic sequence? -6,-2,2,6,10 a.4 b.5 c.3 d.6
