Find equivalent expression
Express 6 as 3 + 3
Apply the following law of indices
So, we have:
Express as 125
Hence, option (b) is equivalent
Answer:
For k = 6 or k = -6, the equation will have exactly one solution.
Step-by-step explanation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots such that , given by the following formulas:
If , the equation has only one solution.
In this problem, we have that:
So
We will only have one solution if . So
For k = 6 or k = -6, the equation will have exactly one solution.
Answer:
10
Step-by-step explanation:
Answer: 0.8
The volume is 8/45 so a•b•c=8/45
So 2/3•1/3•a=8/45
Multiply 2/3•1/3=0.222222 or 2/9
So 2/9•a=8/45
Divide 8/45 / 2/9= 0.8
a=0.8
Hope this makes sense and it helps!!
