Answer:
<u>The equation would be:</u>
<u>p = 10,000 * (1 + 0.2)∧ t</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Current population of a town = 10,000 inhabitants
Growth rate of the population = 20% annually
2. Which equation could be used to find the population after T years?
p = Population of the town after t years
t = Number of years
We will use the following equation:
<u>p = 10,000 * (1 + 0.2)∧ t</u>
For example, let's calculate the population after 6 years, replacing with the real values, we have:
p = 10,000 * (1 + 0.2)⁶
p = 10,000 * 2.986
p = 29,860 inhabitants
To solve this problem, we must substitute the value of -1 in for x in the function. This means that for every x there is in the equation, we must substitute the value -1 in for it in order to find the value of g(-1). This is modeled below:
g(x) = -5x + 13
g(-1) = -5(-1) + 13
Next, we must simplify using the order of operations. PEMDAS outlines this concept, telling us to simplify parentheses first, exponents next, then multiplication and division, and finally addition and subtraction. In this case, we will solve the multiplication and then the addition, as modeled below:
g(-1) = -5(-1) + 13
g(-1) = 5 + 13
g(-1) = 18
Therefore, your answer is 18.
Hope this helps!
Answer:
f(x) = 3x² - 14x - 5
Step-by-step explanation:
multiply the factors: (x + 1/3)(x - 5)
x² - 5x + 1/3x - 5/3
x² -14/3x - 5/3
multiply by 3 to eliminate fractions:
3x² - 14x - 5
