Which of the following is a point at which the tangent to y=(x-2)^2(x+3) is horizontal? a) (-2,16) b) (-1, 18) c) (1,4) d) (2,0) I found the derivative of y=(x-2)^2(x+3) which is 3x^2-2x-8 if I solved for 0, it wouldn't give me the answer that are listed above. What did I ...
So y2-y1=m(x2-x1) y-(-2)=-6(x-(-1) y=6x-1 therefore the slope of tangent is 6?
Determine the slope of the tangent to the curve y=2(x^2+x-1)^3 at (-1, -2)
Determine the coordinates of the point(s) on the graph of y=3x- 1/x at which the slope of the tangent is 7. So the derivative of y=3x- 1/x is y'=3 + 1/x^2 What do I do next?
How many horizontal tangents does the graph of f(x)=(x-1)^2(x-3)^2 have? f(x)=(x-1)^2(x-3)^2 =2(x-1)(1)+2(x-3)(1) =2x-2+2x-6 f'(x)=4x-8 0=4x-8 =4(x-2) x=2 Therefore it only has 1 horizontal tangents?
How long does it take a plane, traveling at a speed of 170 m/s, to fly once around a circle whose radius is 3500 m?
I'm in this class too :/ For this problem, you have to use both equations F=Ma and F=(mv^2)/r Step 1: solve for F using F=Ma 5.70kg x 9.81 m/s^2 = 55.917 N Step 2: plug this into the other equation 55.917N = (2.40kg x v^2)/0.500m (55.917N x .5m)/2.40kg =11.65 m^2/s^2 (squa...
