consider the following quadratic function f(x)= -2x^2+12x+32=0 select all the statements that are true for the function

Naddika [18.5K]

Answer:

The answer to your question is

a) 400

b) The function has two real solutions (-2 and 8)

Step-by-step explanation:

Process

1.- Discriminant = b² - 4ac

= 12² -4(-2)(32)

= 144 + 256

= 400

2.- Solutions (using the general formula)

x = $\frac{- b +/- \sqrt{b^{2}- 4ac}}{2a}$

x = $\frac{- 12 +/- \sqrt{400}}{2(-2)}$

x = $\frac{-12 +/- 20}{2(-2)}$

x₁ = $\frac{-12 + 20}{2(-2)} = \frac{-12 + 20}{-4} = \frac{-8}{4} = - 2$

x₂ = $\frac{- 12 - 20}{- 4} = \frac{-32}{- 4} = 8$

This function has two real solutions (-2, 8)

A military jet flying with the wind travelled 1500 km in 1.5 hrs, but when the plane turned around, it took 1.875 hours to retur

juin [17]

Answer:

With wind = 1000 km /hr

In calm air = 800 km/hr

Step-by-step explanation:

With wind :

Distance traveled = 1500 km

Time taken = 1.5 hours

Speed of plane in air :

Speed = distance / time

Speed = 1500 km / 1.5 hours

Speed = 100 km pe hour

In calm air :

Time taken = 1.875 hours

Distance = 1500 km

Speed of wind in calm air :

Distance / time

1500 km / 1.875

= 800 km/hr
