I being the intercenter of the triangle means that IA = BI= CI
CI = 52-2X
AI = 3X +7 ==> AI = IC ==> 3X+7 = 52-2X SOLVE FOR X
3X+2X = 52-7 ==> 5X = 45 & X =9
IF X = 9 THEN IC = 52-2(9) = 34. IC =34
Answer:
Time t = 2 seconds
It will reach the maximum height after 2 seconds
Completed question;
Amir stands on a balcony and throws a ball to his dog who is at ground level. The ball's height, in meters above the ground, after t seconds that Amir has thrown the ball is given by:
H (t) = -(t-2)^2+9
many seconds after being thrown will the ball reach its maximum height?
Step-by-step explanation:
The equation of the height!
h(t) = -(t-2)^2 + 9 = -(t^2 -4t +4) + 9
h(t) = -t^2 +4t -4+9
h(t) = -t^2 + 4t +5
The maximum height is at dh/dt = 0
dh/dt = -2t +4 = 0
2t = 4
t = 4/2 = 2
Time t = 2 seconds
It will reach the maximum height after 2 seconds
This is a true statement, or false depending on whether Alfonso actually did or not. There's no proof.
so if you do 9 divided by 60 and it will give you 0.15 and that is your answer
I hope this helps if you need any other help just message me and i will answer
