Answer:
Step-by-step explanation:
Give the DE
dy/dx = 1-y
Using variable separable method
dy = (1-y)dx
dx = dy/(1-y)
Integrate both sides
∫dx = ∫dy/(1-y)
∫dy/(1-y)= ∫dx
-ln(1-y) = x+C
ln(1-y)^-1 = x+C
Apply e to both sides
e^ln(1-y)^-1 = e^,(x+C)
(1-y)^-1 = Ce^x
1/(1-y) = Ce^x
Hello,
c1=10.9 (in) A1=392.4 (in²)
c2=21.8 (cm) =21.8/2.54 (in)
k=c2/c1=(21.8/(2.54*10.9)=2/2.54
A2=(2/2.54)²*392.4=243,28848...≈243.29 (in²)
Answer:
oof ok i tried really hard hope you can read it... hope this makes mlre sense.
40(11.28)+6(11.28*1.5)
40(11.28)+6(16.92)
451.2+101.52
$552.72
