2x + 52 = 99 subtract 52 from each side
2x = 47 divide each side by 2
x = 47 / 2
He has
86,423,688,431 - 5422 + 5422(9865) = 86,477,171,039 left
(4x+66)/3 = (13-3x)/4 cross-multiply
4 (4x + 66) = 3(13 - 3x) simplify
16x + 264 = 39 - 9x add 9x to both sides
25x + 264 = 39 subtract 264 from both sides
25x = -225 divide both sides by 25
x = - 9
t = log 80 / log 120 ≈ 0.9153
Yeah........I still have to wrap my brain around it.....LOL!!!!
Note that all we really need to do is to find 2pi * 200 ≈ 1256.64 km
The radius of the first satellite = R1
The radius of the second satellite = R1 + 200
So......orbit of second satellite - orbit of first satellite =
2pi [R1 + 200] - 2pi [ R1] = 2pi [ R1 + 200 - R1] = 2pi *200
Points (a,5) and (9,b) are on the circle x2+y2=125. what are the values of a and b?
a^2 + 5^2 = 125 9^2 + b^2 = 125
a^2 + 25 = 125 81 + b^2 = 125
a^2 = 100 b^2 = 44
a = ± 10 b = ± √44
So...the points are (10, 5), (-10,5), (9, √44), ( 9, -√44)
No need to.....just be sure you're in degree mode [ select at bottom left ]
Connor might be an idiot.....but.....at least he doesn't misuse "your" for "you're "
Thanks, Melody.....I couldn't think how to do this one....but ....I see what you did there....!!!!
