Answer:
see below (I hope this helps!)
Step-by-step explanation:
p² = 4x² * (q(1 + r² / y²) / S)
p²S = 4x² * q(1 + r² / y²)
p²S / 4x²q = 1 + (r² / y²)
p²S / 4x²q - 1 = r² / y²
y² = r² / (p²S / 4x²q - 1)
y = √( r² / (p²S / 4x²q - 1) = √(r²4x²q / (p²S - 4x²q))
let wind velocity=x
speed of plane=y
(x+y)*4=808
x+y=808/4=202 ...(1)
(y-x)*4=488
y-x=122 ...(2)
add (1) and (2)
2y=202+122=324
y=324/2=162
from (1)
x+162=202
x=202-162=40
wind velocity=40 m/hr
speed of plane=162 m/hr
The formula of a slope:
We have the points (-2, 2) and (-4, -2). Substitute:
7x + 2
5 - 4 + 7x + 1
= 1 + 7x + 1
= 7x + 2
hope this helped u bud :)
I think is is 5.4
what I did is divided the problem
