Answer:
i = 7.5
Step-by-step explanation:
(5-3i)+(10+5i)
(5+10)+(5i-3i)
15+2i
15=-2i
15/2-i
7.5=i
Answer:
C 180-123
Step-by-step explanation:
This is because 180 is what triangles always equal and if one angle is 128 then the rest will be answered from this equation
Answer:
P = 36 inches
A = 81 inches ^2
Step-by-step explanation:
This is a square so all the sides lengths are equal
P = 4s where s is the side length
P = 4*9 = 36 inches
A = s^2 where s is the side length
A = 9^2 = 81 inches ^2
Answer:
1) Factor form :
2) 8 second after launch.
Step-by-step explanation:
The height of the ball (in meters above the ground) t seconds after launch is modeled by
To find the time when ball hit the ground, we need to find the factor form of the given function.
When ball hi the ground, then height of the ball from the ground is 0.
Using zero product property, we get
Ball hit the ground at t=0 and t=8. It means ball hit the ground in starting and 8 second after launch.
8 is te answer > i hope that helpped
