Answer:
Step-by-step explanation:
Given function l:
h= -16t² + 26t
where h represents height and t represents time.
The time for dolphin atbthe height 5 feet is given by putting the value of h as 5 in the function,
5 = -16t² + 26t
16t² - 26t + 5 = 0
For this equation: a=16, b=-26, c=5
Use quadratic formula with a=16, b=-26, c=5.
x=(−b±√b2−4ac)/2a
x=−(−26)±√(−26)2−4(16)(5)/2(16)
x=13/16 + 1/16√89 or x=13/16+ −1/16√89
x=1.40 or 0.22

Answer:
1.5
Step-by-step explanation:
225° bisects Q III
315° bisects Q IV
-270° = 90°
405° = 45° bisects Q I
cos(225) sin(315) + sin( –270) tan(405) = ?
(-½√2)(-½√2) + 1(1) = ?
0.5 + 1 = 1.5
The answer for the first one would be 6.4.
And the second one is C. 3.16
