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.
Answer with explanation:
The Given Inequality is
|x-4|<9
Modulus of a number yields always a positive value.
→|x-4|= x-4, when, x-4≥0
That is , x≥4.
= -(x-4), when, x-4<0
means, x<4.
it can be Written as
→ -9<x-4<9
→ -9+4 < x -4+4 < 9+4
→ -5<x<13
→x∈(-5,13)
Answer:
−12
Step-by-step explanation:
8 - 5 = -3
-3 x 4 = -12
Answer: x+6
Step-by-step explanation:
5x-3(x-2)-x .......................... Question
5x-3x+6-x ........................... Distribute
1x+6 ..................................... Combine like terms
x+6 ...................................... Multiply by 1
Answer: -27 is the correct answer. (apparently)
