Step-by-step explanation:
Suppose U = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10} is the universal set and Q = {3, 6, 9). What is Q"?

Answer:
Step-by-step explanation:
U is the universal set, that is, a set that contains the universe of possible sets, which is formed by 10 elements in this. Q is a subset of U formed by three elements: 3, 6, 9. (
)
represents the complement of the complement of 
. The complement of is the subset of 
formed by elements not contained in . which simbolized by 
. That is, 1, 2, 4, 5, 7, 8, 10.
The complement of corresponds to the elements contained in . Hence, the correct answer is .
Answer:
Step-by-step explanation:
The height of the marshmallow (in feet) is represented by the equation h=−16t2+8t+48,
where t is the time (in seconds) after he throws the marshmallow.
The equation is a quadratic equation. When the marshmallow hits the ground, its height from the ground will be zero. Therefore
−16t^2+8t+48 = 0
- 2t^2 + t + 6 = 0
Multiplying through by the negative sign. It becomes
2t^2 - t - 6 = 0
2t^2 + 3t - 4t - 6 = 0
t(2t + 3) - 2(2t + 3) = 0
(t - 2)(2t + 3) = 0
t - 2 = 0 or 2t + 3 = 0
t = 2 or t = - 3/2
The time cannot be negative
So it will take 2 seconds to hit the ground
Answer:
Area of the field that the cow graze = 235.71 sq. ft
Step-by-step explanation:
Area of the field that the cow graze = (120 / 360) * πr²
= (1/3) * (22/7) * 15 * 15
= (22 * 5 * 15) / 7 = 1650 /7
= 235.71 sq. ft
