Given:
The height of ball is represented by the below function:
To find:
The number of seconds it will take to reach the ground.
Solution:
We have,
At ground level, the height of ball is 0, i.e., 
.
Taking out greatest common factor.
Splitting the middle term, we get
Using zero product property, we get
and 
and 
Time cannot be negative, so .
Therefore, the ball will reach the ground after 2 seconds.
If I'm understanding this correctly 20 rounded to the nearest ten would be 20
It would be in a state of loss because the units manufactured neither reaches nor exceeds the break even point.
Given situation: => 18 times 4 to the second power plus (9 minus 3) to the second powerLila answers 324 while Rob answers 360 in the given problem or equation.Now, let's try to solve it to know who got the correct answer:=> 18 x 4^2 + (9 - 3)^2, since we have a parenthesis in our equation, we need to solve it first=> 18 * 4^2 + (6)^2=> 18 * (4* 4) + (6 * 6)=> (18 * 16) + 36=> 288 + 36=> 324<span>Thus Lila got the correct answer</span>
