Answer:
B.) Orthogonal
Step-by-step explanation:
Two vectors u and v whose dot product is u·v=0 are said to be orthogonal
u = <6, -2>, v = <2, 6>
u·v = u1*v1 + u2*v2
6*2 + -2 * 6
=12 -12
=0
Answer:
B.
Step-by-step explanation:
According to the graph the function is defined for all real number except -3 and 7 (where the two red dashed vertical lines cross the x-axis)
so our function should be :

Answer:
Step-by-step explanation:
Alright, lets get started.
This is the combination of three figures semi circle, rectangle and triangle.
We will find the area of each figure and will add them.
The radius of the circle is half of the diameter, so radius is 6.
Area of semi circle will be : 
Area of semi circle is : 56.52
Area of rectangle is: 
So, area of rectangle is:
Area of triangle is : 
So, area of triangle is :
Adding all these three areas, the area of above figure will be:
[tex]Area = 56.52+480+30
Hence Area is 566.52............... Answer
Answer:
$40
Step-by-step explanation:
since 6 x 8 = 48
you need 8 boxes which each cost $5
so
8 x $5 =$40
4/5 of an hour would be 48 minutes. if he still has two thirds to do and it takes 48 minutes to do one third than multiply 48 by 3 and you get your answer: 144 minutes
