1. The height of a pop fly ball over the time after the ball is hit is modeled by the function, , where is the ball’s height in feet above the ground and is the time in seconds after the ball is hit. Use the quadratic formula to find how many seconds it takes for the ball to hit the ground.

2. Give an example of a quadratic equation with real solutions.

3. Give an example of a quadratic equation with non-real solutions.

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

the answer is b.
