Answer:
16.52
Step-by-step explanation: There are more sig figs
2/5 of 100 would be 40%
1/9 an hour would be 1/9 x 40 % = 4.44% every hour
Total hours left would be 40% / 4.44%= 9.0009 = 9 hours
Y = 2(x+3)² - 5
(x+3)² = x(x+3) + 3(x+3) ⇒ x² + 3x + 3x + 9 = x² + 6x + 9
y = 2(x² + 6x + 9) - 5
y = 2x² + 12x + 18 - 5
y = 2x² + 12x + 13 This is the standard form of the equation. Choice D.
Answer:
A. Scalene
E. Obtuse
Step-by-step explanation:
Obtuse are angles that are greater than 90°
Scalene is not congruent sides.
