2.25 for the first mile. That leaves 4.2 miles.
4 * 0.1 = 0.4
0.15 * 4 = $6.00
0.15 * 2 = 0.3
$6.30 + $2.25 = $8.55
$10.00 - $8.55 = $1.45
The driver's tip was $1.45.
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
Find the intercepts
<u>The y-intercept</u> is the value of y when the value of x is equal to zero
so
For x=0 ----->
The y-intercept is the point (0,-1)
<u>The x-intercept </u>is the value of x when the value of y is equal to zero
so
For y=0 -----> ----->
The x-intercept is the point (-1,0)
<em>Find the domain</em>
we know that
The radicand must be positive
so
All real numbers greater than or equal to -1
The range is all real numbers less than or equal to -1
using a graphing tool
see the attached figure
Take the cross product, then normalize the result.
This has norm
and so a unit vector orthogonal to both given vectors is
An equally correct answer would be the negative of this vector, since
.
