Answer:
3m + 13 = 31 I hope this helps you!
1 + -3 1/2 is = to -2.5 so v= -2.5
Answer:
f(t) = 66·0.995^t
Step-by-step explanation:
You can try t=0 and t=1 in each of the formulas to see which one gives values of 66 and 0.5% less than 66, or 65.67.
The first function has an initial value of 0.5, so is not correct.
The second function gives f(1) = 99, so is not correct.
The third function gives f(1) = 65.67, so is correct.
The fourth function gives f(1) = 66.33, so is not correct.
_____
You can realize that the multiplier will be 0.5% less than 100%, so will be 99.5% = 0.995. This number shows up only in the third selection.
Answer: Yes
Step-by-step explanation:
Since the numerator is multiplying square root 13 by square root 2, we can break them apart.
You are correct, 
over is equal to one, so we can "cancel them out" of our expression.
This leaves us with:
