Answer:

- 77

Step-by-step explanation:

To evaluate, substitute x = 4 into g(x) then substitute the value obtained into f(x).

g(4) = 4² + 3 = 16 + 3 = 19

f(19) = (- 4 × 19) - 1 = - 76 - 1 = - 77

If the population of a certain county was 100,000 in 1998 and 110,429 in 2008, and if the formulay = P0ehtapplies to the growth

MatroZZZ [7]

Answer:

126807 people

Step-by-step explanation:

Given;

P= Poe^ht

Where;

P= population at time t

Po= population at the beginning

h= growth constant

t= time

1998- 2008 is ten years.

110429= 100,000e^10h

1.1 = e^10h

ln(1.1) = lne^10h

0.095 = 10h

h= 0.0095

In 2023, t = 25 years

P= 100,000e^(0.0095 × 25)

P= 126807 people

The sleeping heart rate of a black bear during hibernation is about 1/2 of its summer rate.if the sleep heart rate of a bear is

svetlana [45]

Hello!

So, according to the problem, the heart rate of a bear during hibernation is $\frac{1}{2}$ its original amount.

So we can write an equation to help us understand this.

$\frac{1}{2}$ of sr = 28

We can use inverse to make this easier to solve. 2 × 28 = sr.

So, in simple form, we multiply.

28 × 2 = 56

Our final answer would be:

A bears heart rate during the summer would be 56 beats per minutes.
