ANSWER:
x > - 1
STEP-BY-STEP EXPLANATION:
- 10 < x - 9
x - 9 > - 10
x > - 10 + 9
x > - 1
For this case we have the following equation:
H (t) = - 16t ^ 2 + 28t
When the dolphin finishes a jump, then the height is equal to zero.
We have then:
-16t ^ 2 + 28t = 0
We look for the roots of the polynomial:
t1 = 0
t2 = 1.75 s
Therefore, the dolphin takes 1.75 seconds to make a jump.
Answer:
it will take for the dolphin to make one jump about:
t = 1.75 s
Answer:
The answer is: X= -1 and y= -2 so <em><u>(-1,-2)</u></em>
