Answer:
98 degrees
Step-by-step explanation:
the full degree of a triangle is 180 degrees
52 + 30 = 82
180 - 82 = 98
goal:tan^5x=tanx(sec²x-2sec²x+1)
proof: from l.h.s to r.h.s
tan^5x=(tanx)^5=((tanx)(tan²x)(tan²x))
from trigonometry identity
(tan²x)=sec²x-1
tan^5x=(tanx(sec²x-1)(sec²x-1))
=(tanx(sec^4x-sec²x-sec²x+1))
=(tanx(sec^4x-2sec²x+1))
proved
This is the correct answer: 3x^3 - x^2 + 6x - 9

Answer:
The maximum height is:
The ball reaches the ground in 1.79 s.
Step-by-step explanation:
We need to take the derivative and equal to zero to find the time at the maximum height.
(1)
Now, we just need to put t(max) into equation (1) to find h(max)
If we want to get the time when the ball reaches the ground we just need to equal h(t) to zero.
Let's solve this quadratic equation.
We will get two solutions and we must choose the positive value.
t1 = 1.79 u
t2 = -0.10 u
Therefore, the ball reaches the ground in 1.79 u.
