Answer:
b)0, yes
Step-by-step explanation:
Given:
Vectors (4,8) . (6,-3)
Finding inner product of vectors:
= 4x6 + 8x-3
=24-24
=0
Now to check the angle between them using formula a.b=|a|.|b|cosθ
|a|= 
=8.9
|b|=
=6.7
Putting values of a.b=0 and |a|=8.9, |b|=6.7 in a.b=|a|.|b|cosθ we get,
0= 8.9(6.7)cosθ
cosθ =0
θ=90 degrees
Hence the two vectors are perpendicular !
A.
For Deshaun: $75 - $10x
For Ann: $90 - $15x
B.
$75 - $10x = $90 - $15x

Answer:
1.21e+6 seconds
525,600 minutes
Step-by-step explanation:
Seconds in 1 day: 86,400
Seconds in 14 days: 1.21e+6
multiply the time value by 86400
525600
multiply the time value by 525600
Hi there!
Standard form is ax + by = c.
Now, we just need to simplify the equation enough so that we can get the answer:
y = -2/9x + 2
2/9x + y = 2
Since 2/9x + y = 2 is in standard form, it'd be the answer.
Hope this helps!
