Answer:
14.42
Step-by-step explanation:
So what you want to do is multiply 245 by 1.65 (because it’s +65%) and by doing that you get $404.25 :)
19. The balloon hits the ground means -16t2+25t+3=0
After you solve the equation, there are 2 solution ~1.67 or ~-0.11 (the time can not be negative) so the solution is 1.67s
20.substitute t=1 to the function -16(1)2+25(1)+3=-16+25+3=12 ft. So the height is 12ft when t=1
Answer:
Both add up to 180 degrees
