Answer:

Step-by-step explanation:
Well we can use the exponential identity: 
The base must be the same for this to work.
So let's combine like bases: 
We can simplify b^2 * b^3 using this identity to get: b^(2+3) = b^5
This gives us the equation: 
But to take a deeper look as to why this identity holds, let's represent b^2 and b^3 by what it really means:
, so this is really just:
which can be simplified as an exponent:
, hopefully this helps you understand intuitively why this identity makes sense.
So using this identity, we can simplify j^2 * j^4 to j^6
This gives us the equation: 
Answer:
a = 2.6
Step-by-step explanation:
10 + 25a = 75
- 10. - 10
25a = 65
÷25. ÷25
a = 2.6

is interest per 1 year? if so:
interest per year=9%×1000
=90
interest for .5 years=90÷2
=45
1000+90+45=1135
Ans: 1135
Answer:
C.
Step-by-step explanation:
The only thing to do here is just check all of the answers.
A makes no sense, as the number of keys on a keyboard doesn't affect the amount of memory in a computer at all (no correlation).
B makes a bit more sense, but it's still wrong. If a train travels faster, it gets places quicker, or the time goes down. If (If one goes up, the other goes down) is true, then you have negative correlation.
C makes the most sense, as if there's more people at a game, then those more people will probably buy more hot dogs. If (If one goes up, so does the other) is true, then you have positive correlation, which is what we want.
