Answer:

3702

Step-by-step explanation:

Initial population = 4500
Yearly decrease = 3.2%

Formula:

P(t) = 4500*((100 - 3.2)/100)^t = 4500*(0.968)^t
P- population, t- time in years after 2009

In our case t = 2015 - 2009 = 6

Find the value:

P(6) = 4500*(0.968)^6 = 3702 (rounded)

Answer:

The frog population would be 3636.

Step-by-step explanation:

3.2% times 6 is 19.2%. And 19.2% of 4500 is 864. Then you do 4500-864 which is 3636.

For problems 1, 2, and 3, use the function g(x) = sin(6x) .

Fantom [35]

Step-by-step explanation:

1. Amplitude = 1. g(x) = 1 sin(6x). The coefficient 1 is the amplitude. The range of the function is $-1 \le g(x) \le 1$ or, in interval notation, [-1, 1]

2. The period is $\frac{2\pi}{6}=\frac{\pi}{3}$ .

x-intercepts (at the beginning, middle, and end of the period) $0,\,\frac{\pi}{6},\,\frac{\pi}{3}$

Maximum (1/4 of way through period) $\left(\frac{\pi}{12},\,1 \right)$

Minimum (3/4 of way through period) $\left( \frac{\pi}{4}, \, -1 \right)$

an adult elephant that is 10ft tall casts a shadow that is 15ft long. find the length of the shadow that a 8ft telephone booth c

nadya68 [22]

Answer:

The length of the shadow the telephone booth is 12 ft.

Step-by-step explanation:

Given:

An adult elephant that is 10 ft tall casts a shadow that is 15 ft long.

The length of the telephone booth is 8 ft.

Now, to find the length of the shadow the telephone booth casts.

Let the length of the shadow the telephone booth be $x.$

As given, an adult elephant that is 10 ft tall casts a shadow that is 15 ft long.

So, 10 ft is equivalent to 15 ft.

Thus, 8 ft is equivalent to $x.$

Now, to get the length of the shadow of the booth we get cross multiplication method:

$\frac{10}{15} =\frac{8}{x}$

By cross multiplying we get:

$10x=120$

Dividing both sides by 10 we get:

$x=12.$

Therefore, the length of the shadow the telephone booth is 12 ft.
