Use the arc length formula to find the length of the curve y = 4x - 1, -3 lessthanorequalto x lessthanorequalto 2. Check your an
aksik [14]

Answer:

5\sqrt{17} is the answer.

Step-by-step explanation:

y= 4x-1

taking derivative with respect to x ,we get \frac{dy}{dx} = 4\\\\formula \int\limits^a_b {\sqrt{1+(\frac{dy}{dx})^2 } } \, dx \\here a = 2 and b =-3 \\ \int\limits^2_{-3}_ {\sqrt{1+({4})^2 } } \, dx \\ = \sqrt{17} (2-(-3))=5\sqrt{17}

Using distance formula

we have points

at x =-3 the value of y = 4(-3)-1= -12-1 = -13

at x =2 the value of y = 4(2)-1 =7

points are ( -3,-13) and (2,7)

distance formula =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

                             =\sqrt{(2-(-3)^2+(7-(-13)^2}

                             =\sqrt{(5)^2+(20)^2}

                             =\sqrt{425}

                             =5\sqrt{17}
