Answer:

Step-by-step explanation:

let the national average be x

11/100 * x = 11x/100

25.47 - x = 11x/100

100(25.47-x) = 11x

2547 - 100x = 11x

2547 = 11x + 100x

2547 = 111x

x = 2547/111

x = 22.945945945946

22.95

The average walking speed r of a person living in a population P in thousands is modeled by the function, r(p) = 0.37 ln p + 0.0

Veseljchak [2.6K]

Answer:

The average walking speed is 1.48 feet per second

Step-by-step explanation:

we have

$r(p)=0.37ln(p)+0.05$

where

r is average walking speed

p is the population in thousands

In this problem we have

$p=48,000/1,000=48$ ----> because p in the equation is in thousands

substitute the value of p in the equation

$r(p)=0.37ln(48)+0.05$

using a calculator

$r(p)=1.48\ ft/sec$

For what values of a is the distance between P(a,3) and Q(5,2a) greater than √26

Novay_Z [31]

$P(a,3)\ \ \ Q(5,2a)\\\\ PQ=\sqrt{(x_Q-x_P)^2+(y_Q-y_P)^2}\\\\ PQ>\sqrt{26}\\\\\sqrt{(5-a)^2+(2a-3)^2}>\sqrt{26}\\\\\sqrt{25-10a+a^2+4a^2-12a+9}>\sqrt{26}\\\\\sqrt{5a^2-22a+34}>\sqrt{26}\ \ |^{2}\\\\
5a^2-22a+34=26\ \ \ |Subtract\ 26\\\\
5a^2-22a+8=0\ \ \ |Factoring\\\\(a-4)(5a-2)=0\\\\
a=4\ \ or\ \ 5a=2\\
a=4\ \ or\ \ a=\frac{2}{5}$
