Answer:
x = -13 or 2
Step-by-step explanation:
x² + 11x + ¹²¹/₄ = ¹²⁵/₄
(x + ¹¹/₂)² = ¹²⁵/₄
x + ¹¹/₂ = ±¹⁵/₂
x = -¹¹/₂ ± ¹⁵/₂
x = -13 or 2

Answer:
trapezoid
Step-by-step explanation:
y = 4x slope = 4
y' = 4x -16 slope = 4
TA // OM
TA: -1 ≤ x ≤ 0 (limited value)
OM: 3 ≤ x ≤ 5
TA and OM limited in different range, their length is not equal
The shape is a trapezoid

Answer:
17 seconds
Step-by-step explanation:
h(t) represents height, we want to know when the ball will return to a height of 28 feet. So our equation is..
28 = -2t² + 34t + 28
Now solve for t...
0 = -2t² + 34t (subtract 28 from both sides)
0 = t² - 17t (divide both sides by -2)
0 = t(t - 17) (factor out a t)
So
t = 0
or
t - 17 = 0
t = 17
0 seconds is the initial height. At 17 seconds, the ball will return to that height
