In uniform circular motion (circular motion at same speed), (tangential velocity)^2/radius = acceleration towards the center of the circle (centripetal acceleration)
<span>Also, radius is the distance to the center of the circle (track). </span>
<span>So, in your case, 15.4m/s^2 = (30.0m/s)^2/(radius) </span>
<span>radius = (900.m^2/s^2) / (15.4m/s^2) </span>
<span>radius = 58.4m</span>
The point (3/5,4) would lie on the circle if it makes the equation of the circle to be true
Latansha's equation of the circle is wrong
<h3>How to determine her error?</h3>
The given parameters are:
Center = (a,b) = (0,-2)
Radius, r = 7
The equation of a circle is:
This gives
Rewrite as:
In Latanya's first step, we have:
By comparing her first step with x^2 + (y + 2)^2 = 0, we can see that her equation is wrong
Hence, Latansha's error is that she determine the equation of the circle, wrongly.

First, find the difference between each number in the sequence.... 34 - 25 = 9. 25 - 16 = 9 and 16 - 7 = 9... So, there is a constant difference of 9 between each number of the sequence. To find the 30th term, you could expand the sequence out to 30 (which is a good way to check your answer, but tedious)... So, simply add the 1st value of the sequence to the difference and multiply by 30 to find your 30th value.... 7 + 9 x 30 = 16 x 30 = 480.
Therefore, the 30th term is 480.
<span>A radius of a circle is perpendicular to a chord if and only if it bisect the chord.</span>
Answer=12.6
QR=9
QP=6
TU=19
TS=?
The triangles are similar, so the following equation can be made
9 6
____=____
19 x
Cross multiply
9x=114
divide both sides by 9
x=12.6 (with the 6 repeating) or 12 2/3
TS=12.6
