Answer: sec (x)
Step-by-step explanation: sin (2x). cos(2x)
_______ -- __________
sin(x). cos(x)
Step-by-step explanation:
The object will hit the ground after 5 seconds. You can rewrite the quadratic function as a quadratic equation set equal to zero to find the zeros of the function 0 = -16t2 + 80t + 0. You can factor or use the quadratic formula to get t = 0 and t = 5. Therefore, it is on the ground at t = 0 (time of launch) and then hits the ground at t = 5 seconds.
2 - 3d = 4d - 19
Add the opposite to both sides to get the variable on the left side only.
2 - 3d = 4d - 19
-4d -4d
2 - 7d = - 19
Then get the terms w/o variables on the right,
2 - 7d = - 19
-2 -2
-7d = -21
Then divide by the number paired with the variable.
--7d = -21
----- ----- ; d = 3
-7 -7
Final answer = 3
Hope I helped :)
So her best jump is 12% of her 1st jump. So
this is:
best jump = 1.12 * 4.25 m
best jump = 4.76 m
Since the winning jump is 15% lower, so this is only 85%
of the best jump hence:
winning jump = 0.85 * 4.76 m
winning jump = 4.046 m = 4.05 m
