Answer:
a
Step-by-step explanation:
the balloon was at 595 feet
595
then it dropped 495 feet
525-495= 30
the equals 30 means that it is currently 30 feet above the ground
and if it dropped another 15 feet it would not reach the ground, which is zero, the balloon would still be 15 feet above the ground
30-15= 15
so the balloon never reached zero
Answer:
-3 plus/minus square root 17 over 4
Step-by-step explanation:
2x squared = -3x + 1 is the same as 2x squared + 3x -1
a=2 b=3 c=-1
sub those into the formula and you get -3 plus/minus square root of 9 + 8 over 2×2
and then you simplify
Step-by-step explanation:
Start by adding 2 to both sides to get 3r^2 = 48. then divide both sides by 3 to get r^2 = 16. square root both sides to get r = 4.
(11,3) Becuase when you plug it in, 11,3 satisfies the equation.
