Great! If we BOTH got the same answer, it is likely I got the right answer too! Thanx !
250 rot/min x pi x 2r = distance / min
250 x pi x 2 x 29 = 45553.093 in/min
in/min x 60 min/hr x 1 ft/ 12 in x 1mi/5280ft = 43.137 m/hr
60 m/hr x 5280 feet/m x 12 in/ft x 1 hr/60min = 63360 in/min
Circumference = pi x 2r = pi x 30 = 94.2477 inches/circumf
63360 in /min x 1 circumf/94.2477 inches = 672.27 circumf/min = rpm
35 = -2/3x + 5 Subtract 5 from both sides of the equation
30 = -2/3 x Multiply both sides by - 3/2
(-3/2)(30) = x
-45 = x
Agree ! Melody is correct.... ! I was thinking about a^2 and b^4 both being POSITIVE results...but that does not tell us if a or b are positive themselves !
The points are the same x = -4 and x= -2
The solutions to f(x) = g(x) are any points that are on both of the graphs...the points where they intersect.. -2,0 -4, 12
4 x 4 x 4 x 4 = 256
=4ba^(1/2)
I do not know what the rest of your question means.....
x = 500mg price
y= 250 mg price
1800x + 2200y =39200
and
2200x + 2200y =44000
Subtract second from first equation
-400x = -4800 x = 12
So 12 bucks for 500 mg bottle
1800(12) + 2200y = 39200 y= 8 $ 8 for 250 mg tab bottle
2. Start with sin(x) amplitude is 1 want 4 so multiply by 4
4 sin(x) period is 2 pi frequency is 1/2pi want period = 4 frequency = 1/4
1/2pi * m = 1/4 m= modulator
m= 2pi/4 = pi/2
4 sin (x pi/2)
AND shift it up 1....just add 1
4 sin (x pi/2) + 1
