Answer:
10.5625 is the answer I got.
Step-by-step explanation:
I used the process PEMDAS for this equation.
(6.5÷2)^2
6.5÷2= 3.25^2
Now you bring down the new quotient and multiply it by itself.
3.25 x 3.25= 10.5625
we are given
BE=x
ED=x+10
AE=x+1
EC=x+3
we can see that two chords AC and BD are intersecting inside the circle
so, we can use property

now, we can plug values

now, we can multiply them

now, we can move all terms on left side


...............Answer
The length of line segment AB by observation if the diagram in the task content is; 14.
<h3>
What is the length of line segment AB?</h3>
It follows from the task content that the line segment MN can be considered as parallel to line segment AB. This follows from the fact that the vertices of triangle MNO are midpoints of the line segments of triangle ABC.
Consequently, it can be concluded that line segment AB is twice the length of line segment MN and hence, BC = 2 × 7 = 14.

Answer:
The correct option D.
Step-by-step explanation:
The given function is

Where f(d) is the height of the ball at horizontal distance d.
Put f(d)=0, to find the distance where the ball touch the ground.

Quadratic formula:

Using the quadratic formula we get


Therefore the ball is in air between d=-0.146 to d=9.146.
The distance can not be negative, therefore the ball remains in the air between d=0 to d=9.146.

Therefore the correct option is D.
