Answer:
h(t) = -16t2 + 186t + 43
at the ground h = 0
hence; -16t2 + 186t + 43 = 0
solving this quadratic equation using the quadratic formula ; a = -16, b = 186, c = 43 ; x = (-b +-(b2 - 4ac)1/2)/2a
gives t = 11.8 seconds to the nearest tenth (note that the negative root has no practical significance)
Step-by-step explanation:
Answer:
6x - 5 ≥ 8
Step-by-step explanation:
Which inequality corresponds to the sentence "five less than the product of a number and 6 is at least 8"?
The inequality sign of
a) At least = greater than or equal to = ≥
Let us represent the number as = x
Hence: "five less than the product of a number and 6 is at least 8" can be written as:
= x × 6 - 5 ≥ 8
= 6x - 5 ≥ 8
