Answer:
The diameter of the wheel is 32 centimeters
Step-by-step explanation:
we know that
The <u><em>intersecting chords theorem</em></u> states that the products of the lengths of the line segments on each chord are equal.
so
In this problem

substitute the given values

solve for x

Remember that
LK goes through the center of the wheel
That means----> LK is a diameter

therefore
The diameter of the wheel is 32 centimeters
The equation of the best fit line is
y = 0.1073x + 4.5365
where
x is the number of leg press reps
y is the time it takes to do a 40 yard dash
For 22 leg press reps"
y = 0.1073(22) + 4.5365
y = 6.8963 s
I don't know part 1 but
Part B: It's increased 6cm at segment P, decreased 6cm at segment R, stays constant for 1 second at segment Q
Part C: First the Ant takes 3 seconds climbing up 6cm of the hill then stays there for 1 second then takes 3 seconds climbing 6cm back down the hill.
