Getting there.....now yo have the distance to the center of the circle......not to the circle itself.....you need to subtract the radius
Pretty good SBR...BUT the question does not ask for the radius...it asks for how far from the ORIGIN (0,0) to the circle......
I would calculate the distance from the origin to the CENTER (h,k)...then subtract the radius....
y = 2x - 5 this is form y = mx+b m = slope = 2 perpidicular is -1 / 2
y = -1/2 x + b sub in the given point to find 'b'
-3 = -1/2(2) + b b = -2
y = -1/2x -2
- x^2 + 19x + 29 is correct for the dimensions given in the question.
And STOP posting questions MULTIPLE times !!!! Refer to the original thread !!!
2c + 4p = 76 legs
c+p = 26 heads p = 26-c
2c + 4 (26-c) = 76 solve for c, chickens...then p = 26-c
h(t) = 6
6 = -4.9t^2 + 14t-.4
0 = -4.9t^2 + 14t- 6.4 use quadratic formula to find t = 4/7 to 16/7 sec time between it is higher than 6
You are welcome !
rate * time = distance
distance is same so equate:
40 m/hr * x = 30 m/hr (x+1/3) solve for x = 1 hour (be careful....you need to change 20 min into 1/3 hour becuase the other parameters are in miles/hr)
40 m/hr x 1 hr = 40 miles
