8/9 is the fraction in simplest form. 18/16 is the non-simplified version.

On an island there are 7 cities. Each two of them connected by a direct road. How many roads are there?

Gnoma [55]

Answer:

21 roads

Step-by-step explanation:

If each two cities are connected by a direct road, to find the number of roads we just need to solve a combination of 7 choose 2, that is, we need to find all pairs of two cities among the 7 cities:

Combination of 7 choose 2 = 7! / (5! * 2!) = 7*6/2 = 21

So there is a total of 21 roads on the island.

A population of deer inside a park has a carrying capacity of 200 and a growth rate of 3%. If the initial population is 80 deer,

otez555 [7]

Answer:

The population of deer at any given time = 200(e^0.03t) ÷ (1.5 + (e^0.03t))

Step-by-step explanation:

This is an example of logistic equation on population growth

carrying capacity, k = 200

Rate, r = 3% = 0.03

Initial Population, P1 = 80

P(t) =?

P(t) = (P1 (k)(e^rt)) ÷ (k- P1 + P1(e^rt))

P(t) = (80 (200)(e^0.03t)) ÷ (200 - 80 + 80(e^0.03t))

= (16000(e^0.03t)) ÷ (120 + 80(e^0.03t))

= 200(e^0.03t) ÷ (1.5 + (e^0.03t))

Alex_Xolod [135]

Taking the arcsin of both sides of the equation, you get ...

... 90° -x = {-60°, -120°}

So ...

... x = 90° -{-60°, -120°} = {150°, 210°}

The appropriate choice is ...

... 210

What is the constant of proportionality for 6,47.94?

Maurinko [17]

$\boxed{k=7.99}$

<h2>Explanation:</h2>

In this exercise, we have the following point:

$(6,47.94)$

Let's assume that y varies directly as x, so this implies we can writ y as the product of x and some non-zero real constant k. In a mathematical language:

$y=kx$

As you can see, this is the equation of a line whose slope is k and passes through the origin. Therefore, the slope of the line is the constant of proportionality we are looking for:

$Solving \ the \ equation \ for \ k: \\ \\ k\frac{y}{x} \\ \\ Where: \\ \\ x=6 \\ y=47.94 \\ \\ k=\frac{47.94}{6} \\ \\ \therefore \boxed{k=7.99}$
