Call the midpoint M. Then it must satisfy
... M = (R + S)/2
... 2M = R + S . . . . multiply the above equation by 2
... R = 2M -S . . . . . subtract S
Since we need to use this equation several times, it is convenient to calculate ...
... 2M = 2(6, -10) = (12, -20)
All we need to do is subtract the given value of S from this.
10. R = (12 -0, -20 -8) = (12, -28)
11. R = (12 -9, -20 -(-3)) = (3, -17)
12. R = (12 -(-2), -20 -(-7)) = (14, -13)
50.1 is the answer hope this helps and please GIVE ME BRAINIEST and add me as a friend. 86.9-36.8=50.1
The term of shaquil's loan will be 29 days approximatly.
We have given that,
Principle amount (p) = $400
Rate (r)= 250% = 2.5
Interest = $80
t = time (in days) = t/365
<h3>
What is the formula simple interest?</h3>
t = 29.2
t = 29 days
Therefore option (B) is correct.
Therefore the term of shaquil's loan will be 29 days approximatly.

Answer:
t = 1.5 seconds
Step-by-step explanation:
Given that d = −4t^2 + 2t + 6,
where d = distance above the water and
t = seconds.
Let assume that it's a perfect parabola
At the symmetry
t = -b/2a
Where a = -4, b = 2
t = -2/2(-4)
t = 1/4
To determine how long it will take a diver to reach the water’s surface
d = −4t^2 + 2t + 6
At water surface d =0
4t^2 - 2t - 6 = 0
Factorizing the above equation leads to
4t^2 + 4t - 6t - 6 = 0
4t(t + 1) -6(t + 1) = 0
4t - 6 =0
4t = 6
t = 6/4= 3/2 = 1.5 seconds
Since t can't be negative so we ignore the second factor.
