I just graphed this equation, and it shows that the projectile will hit the ground at 5.3 seconds. I could be wrong but I'm going with the calculator is right I hope. I hope this helps you!
C) g-0.1g
You multiply gx0.1 then subtract that from the price of apple (g).
First you'll take 18/2 which equals 9. Then 30/2 which equals 15. Then you can divide both 9 and 15 by 3. So 9/3 equals 3 and 15/3 equals 5. So the answer is 3:5.
You can use the calculator it’s easier and plus you don’t have to put four 9’s
