Answer:
A)
Step-by-step explanation:
uv = u1v1 + u2v2 = (1/3)*18 + 4*(-3/2) = 6 - 6 = 0
Because uv=0, these 2 vectors are orthogonal.

How much farther is she on Tuesday
To do this, we simply calculate the difference between distance covered on both days.
Take LCM
<em>Hence, she ran 13/40 mile farther on Tuesday</em>
I plugged it in to a truncated square pyramid calculator and got v=76
the formula for this shape is V=1/3(A squared+AB+B squared)H.
Hello :
the center of this cercle is : O( 0, 0)
calculate the slope m of the line : OA .. A (3,-4)
m= (yA - yO) / (xA- xO)
m = (-4-0)/(3-0)
m= -4/3
if : k the slope of the tangent : k×m = -1 (the tangent perpendiclar of : OA)
k× (-4/3) = -1
k = 3/4
an equation of this tangent is : y - (-4) = (3/4)(x-3)
This is how I would do it, hope this helps!
