Answer:
x = -30
cos(x - 30) = ½
Step-by-step explanation:
Look at the picture
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

Perpendicular slopes are opposite reciprocals.
This means the slope of the line perpendicular to GA will be the opposite reciprocal of -5.
Reciprocal of -5: -1/5
Opposite of -1/5: 1/5
The slope of the line perpendicular to GA is 1/5.
