First, write each fraction so that it has a common denominator.

1/2 can also be written as 2/4.

6/8 can also be written as 3/4

1/4 is smallest.

From least to greatest:

1/4, 2/4 (1/2), 3/4 (6/8)

Find the center of the circle whose equation is x² + y² = 4.

Varvara68 [4.7K]

Answer:

The center of circle is $(0,0)$

Step-by-step explanation:

We need to find the center of the circle of the equation $x^{2}+y^{2}=4$

Since, the general equation of circle is $(x-h)^{2}+(y-k)^{2} = r^{2}$

Where (h,k) is center of circle and r is radius.

Re-write the circle equation is $x^{2}+y^{2}=4$ as,

$x^{2}+y^{2}=2^{2}$

Compare $x^{2}+y^{2}=2^{2}$ with $(x-h)^{2}+(y-k)^{2} = r^{2}$

so, $(x-0)^{2}+(y-0)^{2} = 2^{2}$

Hence, the center of circle is $(0,0)$

The florida manatee population is 3,000 and is decreasing by 11% each year. Write a function for this situation.

stepan [7]

The required function of the situation is f(x) = 2670x.

Step-by-step explanation:

Given,

Population is = 3000

Evert year it is decreased by 11%.

To find the function of the given situation.

Formula

If the original population is a and is decreased by b% the population after 1 year will be a× $\frac{100-b}{100}$

After x year the population will be = a× $\frac{100-b}{100}$ ×x = $ax\frac{100-b}{100}$

Now,

Let after x years the population will be,

f(x) = 3000x× $\frac{100-11}{100}$

= 2670x

Hence,

The required function of the situation is f(x) = 2670x.
