Product rule:


Power rule:

The exponential function is its own derivative:

Assuming the base of
is
, its derivative is

But if you mean a logarithm of arbitrary base
, we have



So we end up with


Answer: a discount of 25%
Step-by-step explanation:
if you take any number and take 10 percent off then 15 percent off it’s even but 25 percent off is a better discount because it takes more money off the original price
Part A: 3x + 15 = 5x - 25
Part B: x = 20
A. Multiply $5000 by .06, and add it back to $5000 to get the total after one year. This is $5300.
B. Multiply the new amount, or $5300 by .06, and add it back to $5300 to get the total after 2 years. This is $5618.
A. $5300
B. $5618
Lets calculate how much she walks each weeks and then we multiply that by the number of weeks.
weekWalk = 5(2) + 3 = 10 + 3 = 13
therefore, she walks 13 miles per week, if she walked for 29 weeks then we have:
total walked =(29)(13) = 377
so she walked 377 miles total, so her original estimate is not reasonable
