Is there a picture that I can see so I can hopefully help you out?
Only (I) is differentiable over (-5, 5) (and its entire domain, for that matter). This is because the exponential function is continuous and infinitely differentiable.
Answer:
$14.89
Step-by-step explanation:
Retail store = $10 x 5 hrs = $50
Restaurant Manager = $21 x 4 hrs = $84
Total earnings throughout the day = $134
Total time worked = 9 hrs
Avg = Total earnings/Total time
=> 134/9
=> $14.89.
The problem statement is not clear regarding which money is invested. We will assume it is the 80% of $8750 that is set aside for future education. That amount is
... 0.80 × $8750 = $7000
If x represents the amount invested at 7%, then the total interest earned is
... (7000 -x)×4% + (x)×7% = 420
... 280 +0.03x = 420
... x = 140/0.03 ≈ 4666.67
$4666.67 was invested at 7%.
$2333.33 was invested at 4%.
