Now, the bicycle made 3 rotations, namely 3 revolutions, before stopping, one revolution is a full circle, namely 2π radians angle, so 3 times that is 3 * 2π, or 6π.

\bf \textit{arc's length}\\\\
s=r\theta \quad 
\begin{cases}
r=radius\\
\theta =angle~in\\
\qquad radians\\
------\\
r=14\\
\theta =6\pi 
\end{cases}\implies s=14\cdot 6\pi

I assume the question is "how long is the track of water left by the tire?"  The circumference of the tire is the distance around the tire and is equal to:   C = 2·pi·radius <span> C = circumference pi=3.14159 r = radius = 14 inches </span>   The track of water left on the floor by one full rotation of the tire equals one circumference in length.  If the tire rotates 3 full times, the track of water is 3 circumferences long.  Use your calculator to get the answer.

Angelina_Jolie [31]

Answer:

1. Yes

2. Yes

3. No

4. No

Step-by-step explanation:

4(-2) +9>-19 Multiply 4 and -2

-8+9>-19 Add -8 and 9

1 > -19 1 is greater than -19

4(5) +9>-19

20+9>-19

29>-19 29 is greater than -19

4(-10) +9>-19

-40+8>-19

-32>-19 -32 is not greater than -19

4(-7) +9>-19

-28+9>-19

-19>-19 -19 is not greater than -19

What are the solutions of the quadratic equation (x – 8)2 – 13(x – 8) + 30 = 0? Use u substitution to solve.
Dafna11 [192]
It is a quadratic
where x-8 is the squared term
do
x-8=u

u^2-13u+30=0

solve
u=\frac{-b+/- \sqrt{b^2-4ac} }{2a}
u=\frac{-(-13)+/- \sqrt{(-13)^2-4(1)(30)} }{2(1)}
u=\frac{13+/- \sqrt{169-120} }{2}
u=\frac{13+/- \sqrt{49} }{2}
u=\frac{13+/- 7 }{2}
u=\frac{20} }{2} or u=\frac{6 }{2}
u=10 or 3

10=x-8 or 3=x-8
18=x or 11=x

x=11 and/or 18
