Step-by-step explanation:
D because it shows that 1x1/3 is shown on # D
Answer:
The owner should gather more.
Step-by-step explanation:
He should gather more so he can make sure he is correct.
Answer:
v2 - v02 = 2ad
v = final speed = 0 (came to a full stop)
v0 = initial speed (what you want to solve for)
d = stopping distance = 175 feet
Then
v0 = √(-2ad) [Remember a is negative, so the argument of the square root is positive.]
But as you can see, we need the acceleration.
If we knew the time it took to come to a full stop, we could still answer the question. Either way, we need more information than just the stopping distance.

<h3><u>Required Answer</u><u>:</u><u>-</u></h3>
- For finding a,b and c we need to compare it with
![\sf ax^2+by+c=0](https://tex.z-dn.net/?f=%5Csf%20ax%5E2%2Bby%2Bc%3D0%20)
![\sf 2x^2-3y+8=0](https://tex.z-dn.net/?f=%5Csf%202x%5E2-3y%2B8%3D0%20)
<h3>Hence the values are </h3>
![\sf a=2 \\ b=(-3) \\ c=8](https://tex.z-dn.net/?f=%5Csf%20a%3D2%20%5C%5C%20b%3D%28-3%29%20%5C%5C%20c%3D8%20)
Answer:
A + B + C = π ...... (1)
...........................................................................................................
L.H.S.
= ( cos A + cos B ) + cos C
= { 2 · cos[ ( A+B) / 2 ] · cos [ ( A-B) / 2 ] } + cos C
= { 2 · cos [ (π/2) - (C/2) ] · cos [ (A-B) / 2 ] } + cos C
= { 2 · sin( C/2 ) · cos [ (A-B) / 2 ] } + { 1 - 2 · sin² ( C/2 ) }
= 1 + 2 sin ( C/2 )· { cos [ (A -B) / 2 ] - sin ( C/2 ) }
= 1 + 2 sin ( C/2 )· { cos [ (A-B) / 2 ] - sin [ (π/2) - ( (A+B)/2 ) ] }
= 1 + 2 sin ( C/2 )· { cos [ (A-B) / 2 ] - cos [ (A+B)/ 2 ] }
= 1 + 2 sin ( C/2 )· 2 sin ( A/2 )· sin( B/2 ) ... ... ... (2)
= 1 + 4 sin(A/2) sin(B/2) sin(C/2)
= R.H.S. ............................. Q.E.D.

In step (2), we used the Factorization formula
cos x - cos y = 2 sin [ (x+y)/2 ] · sin [ (y-x)/2 ]
