The distance between the two cars is now 320 yards.

Distances</u></h3>
To determine what is the distance between the two cars now if they did not collide the following calculation must be performed:
- 500 - (500 - 405) - (500 - 415) = X
- 500 - 95 - 85 = X
- 500 - 180 = X
- 320 = X
Therefore, the distance between the two cars is now 320 yards.

Answer:
32768
Step-by-step explanation:
Answer:
a) 400 meters
b) 67 meters
c) 124.790 meters
Step-by-step explanation:
Given data :
g1 = - 0.4 %
g2 = +2 %
change of grade of sag curve ( a ) = 0.6 %
Elevation of PVI ( h2 ) = 124.80 m
a) compute the length of the curve using the relation below
a = . hence ; L = ( g2 - g1 ) / a
L = ( 2 -(-0.4 ) / 0.6
= 2.4 / 0.6 = 4
= <em>400 meters</em>
<u>b) compute the elevation of the lowest point of the curve</u>
slope of the vertical curve = 0
0 = 2ax l + b
= 2( ) x + g1
∴ x = = ( 0.4 * 4 ) / ( 2 + 0.4 ) = 1.6 / 2.4 = 0.67 stations
therefore x ( elevation of the lowest point ) = <em>67 meters</em>
C<u>) compute the elevation at Sta. 12 + 125.60</u>
Given that the rate of change of elevation is the same at all points
= = 0.4 -------- ( 1 )
where h2 = 124.80
h1 = ? ( elevation of p0 ) at 12 + 125.60
PVI = 12 + 150.06
p0 = 12 + 125.60
back to the above equation
- h1 = 0.4 ( PVI - P0 ) - h2
= 0.4 ( 12.150 - 12.1256 ) - 124.80
-h1 = -124.790
hence h1 = 124.790 m
Note what i actually represents.
i is the very basis of a whole new level of counting. When finding discriminants, we often say that a quadratic has no
real roots if the discriminant is 0. Needless to say, there are roots, they are just imaginary.
, in real terms, is non-existent. That is, there are no numbers in the real number system that when multiplied by itself produces a result of -1. This is what i unit represents.
Let's tackle this problem in smaller steps.
Let's first expand our brackets.
(i - 7i)² = (-6i)² = 36i²
Now, let's distribute the xi.
xi(i - 7i)² = xi(36i²) = 36xi³ =
= -36xi
