Answer:a and d
Step-by-step explanation:
Answer:
This problem is easier than it appears to be at first glance! If we assume the ground is located at y = 0, then we only use the following equation to solve:
y = -9t + 18
0 = -9t + 18
-18 = -9t
t = 2
Therefore, it takes 2 units of time (whatever units the problem specifically states) for the rocket to hit the ground.
Answer:
Option 2 (Graph B)
Step-by-step explanation:
x ≤ ⁵/4 or x ≥ ⁵/2 represents a compound inequality containing the union of two statements. Either of the statements makes the compound inequality true.
On a graph, the small "o" indicating the start of the value of x would be full, this means ⁵/4 and ⁵/2 are included in the solutions.
Therefore, the correct graph in option 2 (Graph B), where the arrow goes from between 1 and 1.5 to your left, and the other arrow goes from 2.5 to your right.
Answer:
50 seconds, 25 seconds longer
Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
1) 5/0.1=5x10=50 seconds
2) It would take the cooter turtle 5/0.5=25 seconds
50 seconds-25 seconds=It would take the giant tortoise 25 seconds longer
