Answer:
(a) D(t) = 250t -500 miles
(b) Controller has 2 hours, but including time for pilots to divert course or altitude.
Step-by-step explanation:
Given:
two planes at same altitude heading in a collision course.
Plane A at 400 miles from collision point at 200 mph
Plane B at 300 miles from collision point at 150 mph.
Theoretical collision happens in
t = 400/200 = 300/150 = 2 hours
Distance ya of plane A from collision point as a function of time in hours
ya(t) = 400 -200t
Distance yb of plane B from collision point as a function of time in hours
yb(t) = 300-150t
(a) Distance between two planes,
Since the two planes are on courses perpendicular to each other, will need using pythagorean theorem
D(t) = sqrt(ya(t)^2+yb(t)^2)
= sqrt((400-200t)^2+(300-150t)^2)
= 250(t-2)
D(t) = 250t -500 miles
b. time available
Time until D(t) = 0
solve D(t) = 0
D(t) = 0
250(t-2) = 0
t = 2 (two hours)
Answer:
t=1/2
Step-by-step explanation:
There are 36 total possibilities when one rolls a six sided die.
<span><span>(1,1)(1,2)(1,3)(1,4)(1,5)(1,6)</span><span>(2,1)(2,2)(2,3)(2,4)(2,5)(2,6)</span><span>(3,1)(3,2)(3,3)(3,4)(3,5)(3,6)</span><span>(4,1)(4,2)(4,3)(4,4)(4,5)(4,6)</span><span>(5,1)(5,2)(5,3)(5,4)(5,5)(5,6)</span><span>(6,1)(6,2)(6,3)(6,4)(6,5)<span>(6,6).
Out of these possibilities there are 3 that make 4.4 that make make 5. 5 that make 6. 6 that make 7. 5 that make 8. 4 that make 9. 3 that make 10. 2 that make 11 and 1 that makes 12. Now add the combinations 3+4+5+6+5+4+3+2+1. The answer would be 33. </span></span></span>
