The graph of y = 4x2 - 4x – 1 is shown.
11Alexandr11 [23.1K]

Answer:

i) The approximate solutions are: x_{1} \approx -0.207, x_{2} \approx 1.207.

ii) The approximate solutions are: x_{1}\approx -0.5, x_{2} \approx 1.5.

Step-by-step explanation:

i) The best approach to estimate graphically the solution of 4\cdot x^{2} - 4\cdot x - 1 = 0 is graphing the following system of equations:

y = 4\cdot x^{2}-4\cdot x - 1 (1)

y = 0 (2)

And labeling the points in which both intersects each other. We include the result in the image 'solution-i'. The approximate solutions are: x_{1} \approx -0.207, x_{2} \approx 1.207.

ii) The best approach to estimate graphically the solution of 4\cdot x^{2} - 4\cdot x - 1 = 2 is graphing the following system of equations:

y = 4\cdot x^{2}-4\cdot x - 1 (1)

y = 2 (2)

And labeling the points in which both intersects each other. We include the result in the image 'solution-ii'. The approximate solutions are: x_{1}\approx -0.5, x_{2} \approx 1.5.

Volume of a cylinder= (height) x area of the base (circle)

We know the height = 160 cm (given), let's find the radius of the base.

The circumference of the base = 87.92 = 2πR==> R=87.92/(2π) =13.993 cm

Area of circle = πR²=π(13.993)² = 615.128 cm²

Hence the volume of the cylinder = 615.128 x 160 = 92,420.48 cm³
