Let the units of the problem be miles and hours. The first plane's distance from point p can be described by
... x = 150 -450t
The second plane's distance from point p can be described by
... y = 200 -450t
Since their flight paths are at right angles, the Pythagorean theorem can be used to describe the distance between them (s).
... s² = x² + y²
... s² = (150 -450t)² + (200 -450t)² = 22500 -135000t +202500t² +40000 -180000t +202500t²
... s² = 40500t² -315000t +62500 = 2500(162t² -126t +25)
... s = 50√(162t² -126t +25)
Answer:
26-33-40-47-54-61-68-75-82-89-96
When you have two lines in an x shape, vertical angles are the ones opposite each other.
in the example here, the angles with the purple dots are vertical angles and the angles with the blue dots are the other vertical angles
The answer would be 60x-48
Answer:
a<-7/2 or a>1
Step-by-step explanation:
2a+5<-2 or -4a-1<-5
2a<-2-5 -4a<-5+1
2a<-7. -4a<-4
2a/2<-7/2 -4a/-4<-4/-4
a<-7/2 a>1
