Answer:
t=0
Step-by-step explanation:
r=<+1,
>
by differentiating the r vector component by component
r' = <2at, 1>
Two vector are orthogonal when the dot product between them is zero, so:
r'·r=0
<+1,
>·<2at, 1>=2
+2at+t=0
common factor
t(+2a+1)=0
Then, the only real value for t is zero.
-> t=0
To calculate the slope, you can use the formula
In this case,
Your slope is 0/3, which does not make sense so there should be something incorrect about your points.

Answer:
Step-by-step explanation:
Number of phones broken = 3
Number of phones not broken = 15
Total number of phone in the shipment = 18
Since a not broken phone has been randomly selected, the number of phones not broken reduces to 14. And the total number of phones would be 17.
Pr(of newly selected phone NOT broken) =
=
Therefore, the probability of the selected phone not being broken is .
