Answer:
y·y"-(y')= Yy" - y'
2-(y')=2-y'
3=0==0
step-by-step explanation:
use the given functions to set up and simplify 2-(y')
recall d = rt, distance = rate * time.
let's say airplane A is going at a rate of "r", therefore airplane B is moving faster, at a rate of "r + 80".
now, after 3 hours, both planes have been travelling for 3 hours each, and say if A has covered "d" miles, then B has covered the slack of 2490 - d.
Use the slope formula. after you find the slope put it in slope intercept form.
slope formula is
Slope intercept form is y=mx+b m=slope b=y intercept
The answer is 21900
BUT if we count leap years it would be 21915 because there would be 5 leap years
A= 1/2 bxh because if you are trying to find area you have to use the the formula A=1/2 bxh
