A population of 2000 starfish has a yearly per capita population growth rate of 0.012. By next year, how do you expect populatio

Alona [7]

Answer:

It will increase by 24 starfish

Step-by-step explanation:

The population is modeled by the following differential equation:

$\frac{dN}{dt} = rN$

Which has the following solution:

$N(t) = N(0)e^{rt}$

In which N(0) is the initial population and r is the growth rate.

A population of 2000 starfish has a yearly per capita population growth rate of 0.012.

This means that $N(0) = 2000, r = 0.012$

By next year, how do you expect population size to have changed?

This is N(1).

$N(t) = N(0)e^{rt}$

$N(1) = 2000*e^{0.012}$

$N(1) = 2024$

2024 - 2000 = 24

So the correct answer is:

It will increase by 24 starfish

Number 33 in which store can you buy 30 oranges with the least amount of money ?

BartSMP [9]

You simply need to find the price of one orange at each store, and multiply that by 30.

Store A: 5/3= around $1.67= 1.67*30= $50.10

Store B: 3/2= $1.50= 1.5*30= $45.00

Store C: 9/5= $1.80= 1.8*30= $54.00

Store D: $1.25= 1.25*30= $37.50

As you can see above, at Store D, 30 oranges would only cost $37.50, making it the cheapest store to buy oranges.

I hope this helps :)

Please Help It Is Past Due!

Step2247 [10]

Explanation:

First we consider ΔABC and ΔBCD,

∠C=∠C (common)

∠B=∠D= $90\textdegree$

So, ΔABC ≈ ΔBCD (By AA similarity rule )

So by taking corresponding sides in ratios we get

$\frac{AB}{BD}=\frac{AC}{BC}=\frac{BC}{CD}$

Now

$AC.CD=BC.BC\\BC^{2} =AC.CD$ -------- Eqn (1)

Similarly,

We consider ΔABD and ΔABC

∠A=∠A (Commom)

∠B=∠D= $90\textdegree$

So,

ΔABD ≈ ΔABC (By AA similarity rule )

So by taking corresponding sides in ratios we get

$\frac{BC}{BD}=\frac{AC}{AB}=\frac{AB}{AD}$

Now,

$AB.AB=AC.AD\\AB^{2} =AC.AD$ --------Eqn (2)

By Adding both the equation we get

$AB^2+BC^2=AC.CD+AC.AD\\AB^2+BC^2=AC(CD+AD)\\AB^2+BC^2=AC.AC\\AB^2+BC^2=AC^2$

Hence, we proved the pythagorean theorem by using similarity of triangle.
