We have two points on a plane p1(150, 25000), p2(90, 19000) and we can find a linear equation from them, lets calculate the slope:
m = (y2 - y1)/(x2 - x1)
where x1, y1 and x2, y2 are the point's coordinates:
m = (19000 - 25000)/(90 - 150)
m = -6000/-60
m = 100
so we have the slope now, and we can use the equation of the line for a point and having the slope, that equation is:
y - y1 = m(x - x1)
so we substitute:
y - 25000 = 100(x - 150)
y = 100x + 25000 - 15000
y = 100x + 10000
so this is the linear equation that models the airplane descent, when the airplane hits the ground, then y = 0, and we need to find the x, that is the position in relation to the runway:
<span>0 = 100x + 10000
</span>-100x = 10000
x = -100
Answer:
1 hr 55 mins
Step-by-step explanation:
50 mins between 12:10 and 1:00 p.m.
Add 5 mins to change 2:05 to 2:00.
55 mins and 1 hr
I think this is right not sure lol it's been a while since I've done this
There are 80 lights. 28 x 12 divided by 4 minus 4 lights for the 16 inches before the first light.
If 1 ton is 2000 pounds then 7 tons is 14,000 lbs. so if we subtract 2800 from 14000 we get 11200
