Answer:
8x² - 14x - 15
Step-by-step explanation:
(4x + 3)(2x - 5)
8x² - 20x + 6x - 15
8x² - 14x - 15
The answer to your question is 5 and 1.
Have a nice day :)
The explicit formula for an arithmetic sequence is an = a1 + d(n - 1) where a1 is the first term and d = common difference. For this sequence a1 is 7 and d = 13- 7 = 19 - 13 = 25 - 19 = 6
So explicit formula required = 7 + 6(n - 1)
Answer:
2,672.45475 (round if needed)
Step-by-step explanation:
44 percent to a decimal is 0.44
2.5 percent to a decimal is 0.025
6,439.65 × 0.44 = 2833.446 (within 15 days)
6,439.65 × 0.025 = 160.99125 (within 30 days)
2833.446 - 160.99125 = 2,672.45475
Answer:
The enrollment in year 2000 was about 1371
Step-by-step explanation:
Given as :
The number of student enrolled at university in 2006 was 10,325
The increased percentage of student from 2000 to 2006 is 40%
Let the number of students in year 2000 was x
The number of student in 2006 = The number of student in 2000 × ( ![(1 +\frac{40}{100})^{6}](https://tex.z-dn.net/?f=%281%20%2B%5Cfrac%7B40%7D%7B100%7D%29%5E%7B6%7D)
Or, 10,325 = x ×( ![(1 +\frac{40}{100})^{6}](https://tex.z-dn.net/?f=%281%20%2B%5Cfrac%7B40%7D%7B100%7D%29%5E%7B6%7D)
Or, 10,325 = x × ![(\frac{140}{100})^{6}](https://tex.z-dn.net/?f=%28%5Cfrac%7B140%7D%7B100%7D%29%5E%7B6%7D)
Or, 10,325 = x × 7.529
∴ x = ![\frac{10,325}{7.529}](https://tex.z-dn.net/?f=%5Cfrac%7B10%2C325%7D%7B7.529%7D)
So, x = 1371.364
Hence The enrollment in year 2000 was about 1371 Answer
