Find the solutions to each of the simultaneous equation given in the attachment below;
Answer:
f(x) = -2x³ +17x² -32x +23
Step-by-step explanation:
It is usually sufficient to try the values of a couple of points in the offered answer selections to see which one fits.
You have not provided any choices, so I have used the polynomial regression function of a graphing calculator to compute the cubic that will represent these ordered pairs exactly.

- Diameter = 51 cm
- Radius (r) = 51 cm ÷ 2 = 25.5 cm
- π = 3.14
- Circumference
- = 2πr
- = 2 × 3.14 × 25.5 cm
- = 160.14 cm
- Area of a circle
- = πr^2
- = 3.14 × (25.5)^2 cm^2
- = 3.14 × 25.5 × 25.5 cm^2
- = 2041.785 cm^2
