Answer:
5=135
7=45
Step-by-step explanation:
Set them equal to 180. So i started plugging in numbers and subtracting them by 90. Then add it back to the number until i got 180.
Solving the inequality we get
Step-by-step explanation:
We need to find the value of x from the inequality
Solving:
Subtract 8 on both sides:
Divide both sides by (-1). For doing this the sign of inequality is reversed i.e, > is changed into <
So, Solving the inequality we get

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.
The answer is
Step-by-step explanation:
