The population of a town has approximately doubled every 17 years since 1950. If the equation P=Po2k, where Po is the population

natka813 [3]

The population of a town has approximately doubled every 17 years since 1950.

the equation P= $P_02^k$ where Po is the population of the town in 1950, is used to model the population, P, of the town t years after 1950.

When t=17 yrs

P=2 $p_{0}$

for 1 year

The equation becomes

P = $P_02^\frac{t}{17}$ -------------(1)

Our original equation is

$P=P_02^k$ ----------------------------------(2)

equating expression 1 and 2

$P_02^\frac{t}{17}=P_{0}2^k$

Cancelling $P_{0}$ from both sides we get

$2^\frac{t}{17}=2^{k}$

t/17=k

⇒k=t/17 is the solution.

Prove that the two circles shown below are similar.

Setler [38]

Answer:

The scale factor is $\frac{R_{A}}{R_{C}}=\frac{5}{2}$

We can say that both circles are similar.

Step-by-step explanation:

If we move the little circle to the center of the bigger circle, so the translate vector will be (3,5).

Now we realize that the bigger circle is just a dilation of the smaller circle, the scale factor is:

$R_{A}=5$

$R_{C}=2$

$\frac{R_{A}}{R_{C}}=\frac{5}{2}$

Therefore, we can say that both circles are similiar.

I hope it helps you!

Find the geometric mean of four and 10

lawyer [7]

The Geometric mean of 4 and 10 is 6.32

Explanation:

Given:

Two numbers are 4 and 10

Geometric mean, GM = ?

We know,

GM = $\sqrt[n]{a_1 X a_2}$

Where,

n = 2

Substituting the value we get"

$GM = \sqrt[2]{4 X 10} \\\\GM = \sqrt[2]{40} \\\\GM = 6.32$

Thus, the Geometric mean of 4 and 10 is 6.32
