Answer: 9-2 & -2-(-9)
Correct me if I'm wrong.
Step-by-step explanation:
Ln x=5-2
ln x=3
ln x is base e log x
so,
x=e^(3)
x=20.0855369232
Only one triangle is able to be drawn with those measurements and angle
Answer:
Step-by-step explanation:
Hello, this is a geometric sequence so we are looking for a multiplicative factor.
![a_0=600\\\\a_1=a_0 \cdot \boxed{\dfrac{1}{2}} = 300 = 600 \cdot \boxed{\dfrac{1}{2}}\\\\a_2=a_1 \cdot \boxed{\dfrac{1}{2}} = 150= 300 \cdot \boxed{\dfrac{1}{2}}\\\\a_3=a_2 \cdot \boxed{\dfrac{1}{2}} = 75 = 150 \cdot \boxed{\dfrac{1}{2}}](https://tex.z-dn.net/?f=a_0%3D600%5C%5C%5C%5Ca_1%3Da_0%20%5Ccdot%20%5Cboxed%7B%5Cdfrac%7B1%7D%7B2%7D%7D%20%3D%20300%20%3D%20600%20%5Ccdot%20%5Cboxed%7B%5Cdfrac%7B1%7D%7B2%7D%7D%5C%5C%5C%5Ca_2%3Da_1%20%5Ccdot%20%5Cboxed%7B%5Cdfrac%7B1%7D%7B2%7D%7D%20%3D%20150%3D%20300%20%5Ccdot%20%5Cboxed%7B%5Cdfrac%7B1%7D%7B2%7D%7D%5C%5C%5C%5Ca_3%3Da_2%20%5Ccdot%20%5Cboxed%7B%5Cdfrac%7B1%7D%7B2%7D%7D%20%3D%2075%20%3D%20150%20%5Ccdot%20%5Cboxed%7B%5Cdfrac%7B1%7D%7B2%7D%7D)
So, the explicit formula is for n
![\boxed{a_n=a_0\cdot \left(\dfrac{1}{2}\right)^n=600\cdot \left(\dfrac{1}{2}\right)^n}}](https://tex.z-dn.net/?f=%5Cboxed%7Ba_n%3Da_0%5Ccdot%20%5Cleft%28%5Cdfrac%7B1%7D%7B2%7D%5Cright%29%5En%3D600%5Ccdot%20%5Cleft%28%5Cdfrac%7B1%7D%7B2%7D%5Cright%29%5En%7D%7D)
Hope this helps.
