Answer:

Step-by-step explanation:

You want the external angle to be 45°.

If n = number of sides, the external angles are each 360°/n = 45°

n = 360/45 = 8

The shape is a regular octagon.

Initial population=145,201

Total years=2037-2001=36

$\\ \sf\longmapsto S=P\left(1+\dfrac{r}{100}\right)^t$

$\\ \sf\longmapsto S=145201\left(1+\dfrac{5}{100}\right)^{36}$

$\\ \sf\longmapsto S=145201\left(\dfrac{105}{100}\right)^{36}$

$\\ \sf\longmapsto S=145201(1.05)^{36}$

$\\ \sf\longmapsto S=145201(5.79)$

$\\ \sf\longmapsto S\approx 840713$

Y=x+3over 8 proportional or nonproportional

Inessa [10]

Answer:

nonproportional

Step-by-step explanation:

x + 3

------- is definitely nonproportional. The reason for this is that the graph (a

8 straight line) does not pass through the

origin; it's offset by 3/8 unit up from the

origin.
