A runner runs around a circular track. He completes one lap at a time of t = 269 s at a constant speed of v = 4.6 m/s. What is t

AURORKA [14]

Answer:

$\boxed{\text{197 m}}$

Step-by-step explanation:

The formula relating distance (d), speed (s), and time (t) is

d = st

1. Calculate the distance

d = 269 s × 4.6 m·s⁻¹ = 1240 m

2.Calculate the track radius

The distance travelled is the circumference of a circle

$\begin{array}{rcl}C & = & 2 \pi r\\1240 & = & 2 \pi r\\\\r & = & \dfrac{1240}{2 \pi }\\\\& = & 197\\\end{array}\\\text{The radius of the track is }\boxed{\textbf{197 m}}$

Fine the following when a=-2, b=4, c=7 7b-12 over 2ac

iren [92.7K]

Hello!

You have to put the numbers in for the variables in the equation

$\frac{7b - 12}{2ac}$

Put the numbers in

$\frac{7(4) - 12}{4(-2)(7)}$

Combine like terms

$\frac{28 - 12}{-56}$

$\frac{16}{-56}$

The is is $\frac{16}{-56}$ or about -0.29

Hope this help!
