arkansaw:
sqrt(y+1) + sqrt(y-3) = 5

i cant solve this confounded problem i need it an example

sqrt(y + 1) + sqrt(y - 3) = 5
sqrt(y + 1) + sqrt(y - 3) = 5 | -sqrt(y - 3)
sqrt(y + 1) = 5 - sqrt(y - 3) | ^2
y+1 = (5 - sqrt(y - 3) )^2
y+1 = 5^2- 2*5*sqrt(y - 3) + (y - 3)
y+1 = 25- 10*sqrt(y - 3) + (y - 3)
y+1 = 22- 10*sqrt(y - 3) + y | -y
1 = 22- 10*sqrt(y - 3) | -22
-21 = -10*sqrt(y - 3) | *-1
21 = 10*sqrt(y - 3) | /10
21/10 = sqrt(y - 3) | ^2
(21/10)^2 = y - 3 | +3
(21/10)^2 +3 = y
441/100 + 3 = y
441/100 + 300/100 = y
y = 741/100
y = 7.41

ALEX:
Zylinder!!
V=500cm³
d=7cm
r=3,5cm
wie groß ist die Oberfläche??
und wie hoch ist die Höhe??

V=pi*r^2*h
d=2*r

V=pi*(d/2)^2*h
500=pi*(7/2)^2*h
500/(pi*(7/2)^2)=h
h=500/(pi*(7/2)^2)
[input]500/(pi*(7/2)^2)[/input]

Höhe ist ungefähr 13cm.

Mantelfläche: Umfang * Höhe = 2*pi*r*h
Oberfläche: Mantelfläche + 2* Grundfläche = 2*pi*r*h + 2*pi*r^2

[input]2*pi*3.5*13 + 2*pi*3.5^2[/input]

Suppose you purchase a car for a total price of $31,370

P = L[c(1 + c)^n]/[(1 + c)^n - 1]

n: number of months: 12*7
c: monthy interest rate: 9%/12=0.09/12
L: Loan amount

[input]31370*( 0.09/12*(1+0.09/12)^(7*12) )/((1+0.09/12)^(7*12)-1)[/input]
about 505$

[input]31370-505*7*12[/input]
that's 11050$ in interest!
