The equation of the circle that you are looking for is x^2 + y^2 = 100.

You can find this by using the base formula for a circle:

(x - x1)^2 + (y - y1)^2 = r^2

In which x1 is the x-coordinate of the origin, y1 is the y-coordinate of the origin, and r is the radius. So we put in the values we know and simplify.

(x -0)^2 + (y - 0)^2 = 10^2

x^2 + y^2 = 100

Is .0035 infinite or finite

marishachu [46]

0.0032 is finite because it doesn't go on forever. If that number never ended, it would be infinite. I hope this helps!

Can someone help me out with this please? I suck at fractions

164 inches x $\frac{1 foot}{12 inches}$ = $\frac{41}{3}$ ft

147 inches x $\frac{1 foot}{12 inches}$ = $\frac{49}{4}$ ft

2 $\frac{1}{4}$ ft = $\frac{9}{4}$

Perimeter = 2L + 2w - 1doorway

= 2 $(\frac{41}{3})$ + 2( $(\frac{49}{4})$ - $\frac{9}{4}$

= $\frac{82}{3}$ + $\frac{98}{4}$ - $\frac{9}{4}$

= $\frac{82}{3}$ + $\frac{89}{4}$

= $(\frac{4}{4} )$ $\frac{82}{3}$ + $(\frac{3}{3} )$ $\frac{89}{4}$

= $\frac{328}{12}$ + $\frac{267}{12}$

= $\frac{595}{12}$

= 49 $\frac{7}{12}$ ft

******************************************************************************

b) 49 $\frac{7}{12}$ ft ÷ 8ft = 6.2

Suppose the population of a country in 1985 was 145 million. In 1995 it was 190 million. Use the formula P = Ae kt to setup an e

kondaur [170]

Answer: Option B is correct

The expression to estimate the population of the country in 2005 is given by

$P=145e^{20k}\\$

Step-by-step explanation:

Since we have given that

In 1985, there was population of 145 millions.

Similarly,

In 1995, there was a population of 190 million .

Use the formula,

$P=Ae^{kt}\\$

where A denotes the initial population and t denotes the number of years.

So, the expression becomes

$P=145e^{20k}\\$

∵ time period between 1985 to 2005 is 20 years.

So we take t=20 years.

So, the expression to estimate the population of the country in 2005 is given by

$P=145e^{20k}\\$
