Answer:
True
Step-by-step explanation:
All sides of each inscribed triangle are congruent, therefore, the segment bisector AUTOMATICALLY confirms their authenticity.
Answer:
(60 - 4x)(50 + 2x) = 2,800
Step-by-step explanation:
-4 is less than -5 even though they are both on the same side of the number line. -4 is closer to zero.
T = 5, so after 5 years
p(t) = t^3 - 14t^2 + 20t + 120
Take derivative to find minimum:
p’(t) = 3t^2 - 28t + 10
Factor to solve for t:
p’(t) = (3t - 2)(t - 5)
0 = (3t - 2)(t - 5)
0 = 3t - 2
2 = 3t
2/3 = t
Plug 2/3 into original equation, this is a maximum. We want the minimum:
0 = t - 5
5 = t
Plug back into original:
5^3 - 14(5)^2 + 20(5) + 120
125 - 14(25) + 100 + 120
125 - 350 + 220
- 225 + 220
p(5) = -5
