Answer:
183.27miles
Step-by-step explanation:
Note that we are considering two planes.
Plane 1
Speed = 140 mph
Time = 2.5 hours
Distance = ?
Speed = distance/time
140 mph = distance/2.5hrs
Distance = 140×2.5
= 350miles
Plane 2
Speed = 170 mph
Time = 2.5 hours
Distance = ?
Speed = distance/time
170 mph = distance/2.5hrs
Distance = 170×2.5
= 425miles
The angle between side is 25 degree
From cosine rule
c^2 = a^2 + b^2 − 2abcos(tetha)
Where a = 350
b = 425miles
c^2 = 350^2+425^2-2(350×425)(cos25)
c^2 = 122500+180625-297500(0.906)
c^2 = 303125-269535
c^2 = 33590
C = √33590
C = 183.27miles
The distance they flew apart after 2.5hrs is 183.27miles
First, we need to find the slope:
m=rise/run OR
m=(2+2)/(-6-2)
m=4/-8
m=-1/2
second we need to find the equation for the line using point-slope form:
y-(-2)=-(1/2)(x-2)
to find "a" we plug in the given y value and solve for x (in this case x=a):
so, a=6 and the point becomes (6,-4)
Answer:
Rounded to the nearest tenth: in
Rounded to the nearest hundredth: in
Step-by-step explanation:
We have a right triangle with a given angle of 35°. We also have the opposite side of that angle, , and its hypotenuse 10 in. To find , we are using the trig function that relates the opposite side with the hypotenuse; in other words, the sine trig function.
Rounded to the nearest tenth: in
Rounded to the nearest hundredth: in
answer
-8>0
step by step
-8:--------. NB you owe something or someone
0: you don't have anything or you don't owe anything
