x less than or equal to 5
hope this helps !!
Answer:
Therefore the length of AB is 15 unit.
Step-by-step explanation:
Given:
A ≡ ( -7 , 4 ) ≡ (x₁ , y₁)
B ≡ ( 8 , 4 ) ≡ (x₂ , y₂)
C ≡ ( 8 , -3 )
D ≡ ( -7 , -3 )
To Find:
Length of AB =?
Solution:
Distance Formula between two points is given as
Substituting the values we get
Therefore the length of AB is 15 unit.

Two integers<span> with polar signs can have the same absolute value.</span>
<span> Absolute value measures the displacement of a number from 0 disregarding the direction. Examples are: </span>
1.-8 and +8, their absolute values is |8| = 8 <span>
2.+ 5 and -5 = |5| = 5</span> <span>
3.1 + 2 absolute value is 3</span> <span>
4.-10 + 2 = usually the answer is -8 but its absolute value is 8</span> <span>
5.Same with -6 = |6| = 6</span><span> </span>
The ball takes 6 seconds to reach the ground.
<u><em>Explanation</em></u>
Height of the ball after seconds is represented by....
The height of the ball is 0 feet when it hits the ground. So, for finding the number of second the ball takes to reach the ground, <u>we will just plug into the above equation and then solve for .</u>
Thus...
Using zero-product property....
and
(Negative value is ignored as time can't be negative)
So, the ball takes 6 seconds to reach the ground.
