Answer:
Answer:
x = 11
Step-by-step explanation:
Since this is a triangle, all interior angles add up to 180 so:
57 + 73 + 3x + 17 = 180
3x + 147 = 180
3x = 180 - 147
3x = 33
x = 11
Answer:
Step-by-step explanation:
The position equation is given as
and we are looking for the times when the position of the ball is 9 feet. That means that we simply plug in a 9 for s(t) and factor to solve for t:
and
and this is what we factor to find t:
t = .42 sec and then again on its way back down at t = .89 sec
So, Simplified as mixed number equals to
(
Keep in mind that the LCM was 8.)
2/3X + 8 +2/3X = 4
4/3X + 8 = 4
4/3X = -4
X = -12/4 = -3
