Answer:
Therefore the ball strikes the ground 5.98 s after kick.
Step-by-step explanation:
Given that , a ball is kicked in the air. The height of the ball can be calculated using the equation where h is height in feet and t is time in second.
When the ball touches the ground then the height will be zero.
i.e h(t)=0
Therefore
Since -2≠0 then
[The solution of a quadratic equation ax²+bx+c=0 is
here a=8, b=-32 and c=-95]
Therefore t= 5.98 or -1.98
since time can not be negative So , t=5.98 s
Therefore the ball strikes the ground 5.98 s after kick.
Answer:
x = -3
y = 4
Step-by-step explanation:
3x+22=10x-41
-22 -22
----------------------
3x=10x-63
-10x -10x
-----------------
-7x=-63
divide by -7 on both sides
yep ur right its x=9
