Answer:

5

Step-by-step explanation:

\displaystyle \lim_{h \to 0} \frac{f(2+h)-f(2)}{h}

\displaystyle\lim_{h \to 0} \frac{(2+h)^2 + 2 + h + 1 - 2^2 - 2 - 1}{h}

\displaystyle\lim_{h \to 0} \frac{4 + 4h + h^2 + h - 4}{h}

\displaystyle\lim_{h \to 0} \frac{h^2 + 5h}{h}

\displaystyle\lim_{h \to 0} h + 5

= 5

Mark takes a bank loan of $3,600 to start up a business at an annual interest rate of 8%. How much will he have to repay in 16 m
Dimas [21]

Answer:

  A.  $3,984

Step-by-step explanation:

The amount of interest is computed from ...

  I = Prt

For the given values, the interest is ...

 I = $3600×0.08×(16/12) = $384

Then the total amount that needs to be repaid is ...

  Principal + Interest = $3600 +384 = $3,984

_____

The time period is 16 months, so is 16/12 years.

The time periods of the interest rate and "t" in the formula must match. If the interest rate is an annual rate, then "t" is in years. If the interest rate is a monthly rate, then "t" is the number of months.

Advocard [28]
If 12= 3/4, then 16=4/4 would be a full tank.

The question is asking how many half gallon bottles can be filled, if there’s 16 full gallons, you’d multiply 16 by 2, and get 32.

Your answer is 32 half gallons
