Answer: time to reach maximum height = 605
Step-by-step explanation:
The expression that relates height with time is
M(d)=-0.123x^2+148.83x-21.07
Where time = x
d = height
The expression is a quadratic equation. If height of the object is plotted against time, the resulting graph is a parabola whose vertex is equal to the maximum height attained by the object. The time, x corresponding to the vertex is the time for it to reach maximum height.
To find x,
x = -b/2a
Where a= 0.123
b = 148.83
x = - 148.83 / -2 × -0.123
x = -148.83 / -0.246
= 605
Substituting x = 605 in the equation,
M(d)=-0.123x^2+148.83x-21.07
d = -0.123 × 605^2 + 148.83×605
= - 45021.075+ 90042.15
= 45020.4
Approximately 45000 feet
Answer:
(-1)/28
Step-by-step explanation:
Simplify the following:
((-19)/2×1/38)/7
(-19)/2×1/38 = (-19)/(2×38):
((-19)/(2×38))/7
(-19)/(2×38)×1/7 = (-19)/(2×38×7):
(-19)/(2×38×7)
The gcd of -19 and 38 is 19, so (-19)/(2×38×7) = (19 (-1))/(2 (19×2) 7) = 19/19×(-1)/(2×2×7) = (-1)/(2×2×7):
(-1)/(2×2×7)
2×2 = 4:
(-1)/(4×7)
4×7 = 28:
Answer: (-1)/28
