I just had this question for homework too!
c = 4v + 1
v + c = 121
Now use substitution.
v + 4v + 1 = 121
5v + 1 = 121
5v = 120
v = 24
The answer is 24.
So let's leave the 112 aside for now. The question then becomes how to write the decimal 0.001 as a fraction. The key is to remember that
0.x corresponds to "tenths" so x/10
0.0x corresponds to "hundredths" --> x/100
0.00x corresponds to "thousandths" --> x/1000
The number 0.001 is just 1 thousandth, or 1/1000
Now back to 112.001. You can write it as
112/1 + 1/1000 =
(112,000+1)/1000 =
112,001/1000 (the fraction you were looking for)
Let me know if you have questions
R = 230 m
v = 17 m/s
Formula: |Ac| = v^2 / r
Point A
|Ac| = v^2 / r = (17m/s)^2 / (230m) = 1.257 m/s^2
Components:
cos(25) = - [ x-component / |Ac| ] => x-component = -|Ac|*cos(25)
sin(25) = - [y-component / |Ac| ] => y-component = - |Ac|*sin(25)
x-component = - 1.256 * cos(25) m/s^2 = - 1.139 m/s^2
y-component = -1.256 * sin (25) m/s^2 = - 0.531 m/s^2
Point B
|Ac| = 1.256
x-component = - 1.256 cos(58) = - 0.666 m/s^2
y-component = + 1.256 sin(58) = + 1.065 m/s^2

Based on the graph, AD passes through -30 of the x - axis and DC passes through -15 of the y-axis.
These lines are the boundaries. Point P is located within said boundaries.
Since Point P is 5 feet from AD, it is in -25f the x-axis.
Since Point P is 5 feet from DC, it is in -10 of the y-axis.
Thus, Point P has the coordinates (-25,-10). It is located on the 3rd quadrant of the plane.
