Answer:
Step-by-step explanation:
WE willl solve the question for the following equation 
1. Add 8c on both sides


2. Add 10 on both sides


3. Substract 2c on both sides


4. Divide both sides by 2


Then, the equation is solved.
Answer:
a(9) = 150*(0.4)^8 = 0.098304
Step-by-step explanation:
This is a geometric sequence, because each new term is 0.4 times the previous term.
The general formula for a geometric sequence is a(n) = a(1)*r^(n - 1). Here, with a(1) = 150 and r = 0.4, we have:
a(n) = 150*(0.4)^(n - 1), and so
a(9) = 150*(0.4)^8 = 0.098304
Answer:

Step-by-step explanation:
We only see the Moon because sunlight reflects back to us from its surface. But the the lit side does not always face the Earth. As the moon circles the Earth, the amount of the lit side we see changes.
