Answer:
43.82 mph
266.67 feet
Step-by-step explanation:
Given :
S = √30fl
S = speed of car
f = drag Coefficient
l = Length of skid mark
If f = 0.8 ; l = 80 feets
s = √30fl
s = √(30*0.8*80)
s = √1920
s = 43.817
s = 43.82 mph
B.)
s = 80 mph
f = 0.8
s = √30fl
80 = √30*0.8*l
80 = √24l
Square both sides
80² = 24l
6400 = 24l
l = 6400/24
l = 266.67 feets

To know whether the shape is the pre-image or the resulting shape, we need to look at its name.
In this instance, the name of the pre-image is GHIJ.
The resulting name of the shape would be G'H'I'J'.
An apostrophe is placed after every letter to signify that it is the resulting coordinate of the original.

Answer:
Part--1:
We know that a equation in point-slope form is represented by:
<em> y-y1=m</em>
<em />
where m is the slope of the line and is a point through which the line passes.
<em />
<em> </em>
<em />
Consider a equation in a point-slope form as:
This means that the slope of the line is: 5
and the line passes through the point (1,5).
Part--2:
Now as we know that if a line has a slope as m then the perpendicular line has a slope: -1/m
Since,
Let this perpendicular line passes through (2,6)
Hence, the equation of a line in point slope form is given by:
