Answer:
Step-by-step explanation:
1. 9 4 5 2 3 5 . 3 2 1
Ones : 5
Tens : 3
Hundreds : 2
Thousands : 5
Ten Thousands : 4
Hundred Thousands : 9
Tenths : 3
Hundredths : 2
Thousandths : 1
2. 5 6 9 3 4 3 5 . 1 2 3
Ones : 5
Tens : 3
Hundreds : 4
Thousands : 3
Ten Thousands : 9
Hundred Thousands : 6
Million : 5
Tenths : 1
Hundredths : 2
Thousandths : 3
These numbers would be -5 & 6...
(-5)(6) = -30
-5 + 6 = 1
D Robby got a credit of -245.75 for returning the guitar but purchased the new one for +368.45=+122.70 that Robby still owes for the bass guitar.
I agree. The answer is choice B
=========================================================
f ' (1) is shown to be positive
f ' (2) is shown to be positive as well
There are no critical values between x = 1 and x = 2, so f ' (x) is positive on the interval 1 < x < 2, so f(x) is increasing on this interval
All of this points to either choice A or choice B
--------------------------------
Similarly,
f ' (3) is negative
f ' (4) is negative
so f ' (x) is negative where 3 < x < 4 due to no other critical values being between x = 3 and x = 4
Based on these facts alone, the answer is either choice B or choice D
But we know that it can't be choice D as we determined it was between A and B. This rules out choice D
So all that's left is choice B
