there is an 'e' key first row, 5th key

1/7 = \(\sqrt{}\)f     square both sides to get

1/49 = f

or   .02040816 = f

I don't think I can see the whole question, but looking at the previous answers, you need tan 54 degrees and 53 minutes

Tan (54+53/60) = 1.4219766     Rounded to 4 dec places   1.4220

= 2.6(5.5p) - 2.6(12.4) = 127.92

=14.3p - 32.24 =127.92

14.3p = 127.92 + 32.24

14.3p=160.16

p=160.16/14.3 = 11.2

Agree with Guest #1  ... if you do it all on the calculator without 'rounding' you will find n = 5

Divide both sides by (x-2)

to get

f(x) = x^2-2x-15    or  f(x) = (x-5)(x+3)

Craft One reaches zero velocity when?

v=vo + at  = 525 + (-15.5)t = 0  Solve for t = 33.87 sec

How far did it travel in 33.87 secs?

x = xo + vo t + 1/2a t^2

x= 0 + 525(33.87) + 1/2(-15.5)(33.87)^2 = 8891.13 meters

Craft 2 has to cover  13500 meters - 8891.13 meters = 4608.87 meters i the same amount of time (33.87 seconds)

 FOR CRAFT 2 :

x = xo + vo t + 1/2 a t^2   and

v = vo + a t = 0   or   a t = -vo      substitute into the equation above

4608.87 = 0 + vo (33.87)  + 1/2 (-vo)(33.87)      results in vo = 272.15 m/s

then   vf = vo + a t      = 272.15 + a (33.87) = 0      a= -8.04 m/s^2

pi radians = 180 degrees    (or 2pi radians in 360 degrees)

160/180 x pi = 8/9 pi radians  = 2.7925 R
