Answer:
m ≥ 0
Step-by-step explanation:
Since the cost is represented by c = 0.12m, the domain should be a positive number, this is because number of minutes can't be written in negative. Therefore, the most reasonable number for the domain would be the set of positive whole numbers which means, m≥0.
Answer:
Step-by-step explanation:
13p⁵ + 6p - 12p² -(-9p - p² - 13p⁵) = 13p⁵ + 6p - 12p² + 9p + p² + 13p⁵
{Distribute (-1) to the second expression}
= <u>13p⁵ + 13p⁵</u> <u>-12p² + p²</u> <u>+ 6p + 9p</u>
{Combine like terms}
= 26p⁵ - 11p² + 15p
Answer: 6
Step-by-step explanation: First, let's find the least common denominator between the 2 fractions, which is 4. Now let's multiply 9/2 by 2 to get the denominator of 4. Once you multiply the numerator and denominator by 2 you would get 18/4. So now the problem turns into how many 3/4 goes into 18/4. We know that 3/4 x 6 = 18/4. So the final answer is 6.
The exponential equation (in thousands) is:
![V = 28 e^{-rt}](https://tex.z-dn.net/?f=V%20%3D%2028%20e%5E%7B-rt%7D)
plug in t=3 yrs, and solve for 'r'.
![14 = 28 e^{-3r} \\ \\ \frac{1}{2} = e^{-3r} \\ \\ ln(\frac{1}{2}) = -3r \\ \\ r = \frac{ln(\frac{1}{2})}{-3} = 0.231 = 23.1%](https://tex.z-dn.net/?f=14%20%3D%2028%20e%5E%7B-3r%7D%20%5C%5C%20%20%5C%5C%20%5Cfrac%7B1%7D%7B2%7D%20%3D%20e%5E%7B-3r%7D%20%20%5C%5C%20%20%5C%5C%20ln%28%5Cfrac%7B1%7D%7B2%7D%29%20%3D%20-3r%20%5C%5C%20%20%5C%5C%20r%20%3D%20%5Cfrac%7Bln%28%5Cfrac%7B1%7D%7B2%7D%29%7D%7B-3%7D%20%3D%200.231%20%3D%2023.1%25)
