Question 288888: I need help with this problem: The formula in Exercise 109 accounts for the effect of gravity only on a falling object. According to that formula, how long would it take a sky diver to reach the earth when jumping from 17,000 feet? (A sky diver can actually get about twice as much falling time by spreading out and using the air to slow the fall.)
The formula is t = sqrt. h/sqrt 16

Question 289055: Solve b^4+b^2-20=0
thanks
...by any chance, is this answer correct: -2,2,-i radical 5, i radical 5?








These are my steps...please tell me if I found out the correct answer, and if I didn't, please show me the correct answer....thanks
b^2=x
b^4+b^2-20=0
x^2+x-20=0
x^2+5x-4x-20=0
x(x+5)-4(x+5)=0
(x+5)(x-4)=0
{b^2+5}{b^2-4}=0
(b^2+5)(b+2)(b-2)=0
b=2,-2
b^2=(-1)(5)
b= radical (-1)(5)
b= +/- i radical 5
b^2+b( i sqrt 5)- b( i sqrt 5)- (i^2)(sqrt 5^2)
b^2-(-1)(5)
i^2=-1
=b^2+5
So, is it correct that the answers are: -2,2,-i radical 5, i radical 5?
