Step-by-step explanation:
we have
where
r is average walking speed
p is the population in thousands
In this problem we have
----> because p in the equation is in thousands
substitute the value of p in the equation
using a calculator
Step-by-step explanation:
slope = x factor = - 5/2
Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1
New slope = 2/5 = m
y = mx + b
from the point given y = 2 | x = -4
2 = (2/5 × -4 ) + b
2 = - 1.6 + b
b = 3.6
