Answer:
13
Step-by-step explanation:
By angle bisector property:
![\frac{28}{49} = \frac{12}{2x + 7 - 12} \\ \\ \frac{4}{7} = \frac{12}{2x - 5} \\ \\ 4(2x - 5) = 12 \times 7 \\ \\ 8x - 20 = 84 \\ \\ 8x = 84 + 20 \\ \\ 8x = 104 \\ \\ x = \frac{104}{8} \\ \\ x = 13](https://tex.z-dn.net/?f=%20%5Cfrac%7B28%7D%7B49%7D%20%20%3D%20%20%5Cfrac%7B12%7D%7B2x%20%2B%207%20-%2012%7D%20%20%5C%5C%20%20%5C%5C%20%5Cfrac%7B4%7D%7B7%7D%20%20%3D%20%20%5Cfrac%7B12%7D%7B2x%20%20-%205%7D%20%20%5C%5C%20%20%5C%5C%204%282x%20-%205%29%20%3D%2012%20%5Ctimes%207%20%5C%5C%20%20%5C%5C%208x%20-%2020%20%3D%2084%20%5C%5C%20%20%5C%5C%208x%20%3D%2084%20%2B%2020%20%5C%5C%20%20%5C%5C%208x%20%3D%20104%20%5C%5C%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B104%7D%7B8%7D%20%20%5C%5C%20%20%5C%5C%20x%20%3D%2013)
The y is adding up by 0.5
0.5+ 0.5 =1 +0.5 =1.5 etc....
For every 1 (x), 0.5 gets added
Answer:
The solution of the inequality is a < 0.2870
Step-by-step explanation:
* Lets talk about the exponential function
- the exponential function is f(x) = ab^x , where b is a constant and x
is a variable
- To solve this equation use ㏒ or ㏑
- The important rule ㏒(a^n) = n ㏒(a) OR ㏑(a^n) = n ㏑(a)
* Lets solve the problem
∵ 13^4a < 19
- To solve this inequality insert ㏑ in both sides of inequality
∴ ㏑(13^4a) < ㏑(19)
∵ ㏑(a^n) = n ㏑(a)
∴ 4a ㏑(13) < ㏑(19)
- Divide both sides by ㏑(13)
∴ 4a < ㏑(19)/㏑(13)
- To find the value of a divide both sides by 4
∴ a < [㏑(19)/㏑(13)] ÷ 4
∴ a < 0.2870
* The solution of the inequality is a < 0.2870
Jim's time is 5:50 and John's time is 6:40.
Answer: We know that the acorn falls from the height of 25 feet above the ground, it means the initial time when it falls is t = 0. The time when it lands on the ground is t = 1.25
