Circumference 
2*pi*r
2*(22/7)*(9/2)
2*(11/7)*9
198 / 7
28.28 cm

so 56.52 is not correct

Answer:

Step-by-step explanation:

OMG!!!!! why don't you just SAY YOU WANT a BLEEPING  REFLECTION!!!

I had to search through a slew of your questions to get clues as to what to do.

To reflect over the x axis, just negate the y term and leave the x term as it is.

M becomes (2, -1)

N becomes (-3, -1)

P becomes (-1, -4)

A town's population has been growing linearly since 2000. In 2003 the population was 70100. In
I am Lyosha [343]

The town's population in 2008 is  78,600.

<h3>What is the population in 2008?</h3>

If the town's population is increasing linearly, it means that it increases by a constant number each year.

Linear equations have this form:  a + bt

Where:

  • a = initial value
  • b = rate of increase
  • t = number of y ears

The rate of linear increase = (population in 2006 - population in 2003) / (2006 - 2003)

(75,200 - 70,100) / 3

5100 / 3 = 1700

P(t) = 70,100 + 1700t

Population in 2008 = 70,100 + 1700(2008 - 2003)

70,100 + 1700(5)

70,100 + 8,500 = 78,600
