Answer:
It would take you 9 hours
Step-by-step explanation:
Speed (s) = Distance (d) / Time (t)
given that; Speed = 42 miles/hour
Distance = 361 miles
42 miles/hour = 361 miles / Time (t)
Time (t) * 42 miles/hour = 361 miles
Time (t) = 361 miles / 42 miles/hour
Time (t) = 8.59 hours
≈ 9 hours (to the nearest hour)
Substituting 3 for x:
-4(3)+9
-12+9
-3

(a)
Given:
is in xy plane and
is in the direction of k.
|a|=6 units, |b|=3 and θ = 90°
|a × b| = |a| × |b| sinθ
= |a| × |b| sin90°
= 6 × 3 × 1
|a × b| = 18
(b)
Let
is perpendicular to both
.
In this case,
x-component of
is positive.
y-component of
is negative.
z-component of
is zero.
