Option A
The centripetal acceleration is 1.32 
<em><u>Solution:</u></em>
From given question,
A cyclist rides in a circle with speed 5 m/s
The circle has a radius of 19 m
To find: Centripetal acceleration
<em><u>The formula for Centripetal acceleration is given as:</u></em>

Where,
= centripetal acceleration
r is the radius and v is the velocity
From given statement,
radius = r = 19 m
velocity = v = 5 m/s
<em><u>Substituting the values in above formula, we get</u></em>

Thus centripetal acceleration is 1.32 
Y-4=5x+10 is the simplified version of this equation
Answer:

Step-by-step explanation:
Given:
The speed of the radio is
meters per second.
The distance of the satellite from the earth is
meter
The formula of the speed is

For time the formula is.

put distance and speed value in above equation.





Therefore, the radio will be take the time is
or 0.12 seconds.
Answer and explanation:
<h2>X</h2>
3x + 6y = 180 <em>Use the original expression to find x</em>
3x = 180 - 6y <em>Subtract 6y by both sides</em>
<em>Divide by 3 to get x</em>
x = 60 - 3y
<h2>Y</h2>
x = 60 - 3y <em>Use the new expression to find y</em>
x - 60 = - 3y <em>Subtract 60 by both sides</em>
<em>Divide by -3 to get y</em>

You know that for the rule, you are at least adding one to “x.”
