Question

Evaluate the expression for b=5,c=0.5, and d=9.4. Write your answer as a decimal or whole number.

Answer 1

To evaluate the expression, substitute the given values of b, c, and d into the quadratic equation.

Step-by-step explanation:

To evaluate the expression, substitute the given values of b, c, and d into the quadratic equation. The quadratic equation is of the form at² + bt + c = 0. Given constants: a = 4.90, b = 14.3, and c = -20.0. The solutions are given by the quadratic formula:

x = (-b ± sqrt(b² - 4ac)) / (2a)

Plugging in the values b = 5, c = 0.5, and d = 9.4 into the quadratic equation:

4.90(5)^2 + 14.3(5) - 20.0 = 0

Simplify the equation and solve for x to find the answer.
