It's the third choice. Since the symbol is not greater than or equal to -3 so it must got left..
Answer:
At 1.5 seconds and 2.5 seconds
Step-by-step explanation:
Because this is parabolic motion, the object will reach the height of 68 feet when it's going up AND when it's coming down. In order to find out those times, you set the h on the left side of the equation equal to 68, because h stands for height.
Set that equal to 0 and factor to solve for t:
Using the quadratic formula, we get t = 1.5 and t = 2.5
I can read it take a better picture
Answer: she would have to use 5 seed packets
This is because every seed packet has 15 plants so 15 x 5 would equal 75
If you only use 4 packets you would be short 5 plants so you have to add another packet to get all 65 plants
