The equation C(l) = l3 – l2 + l + 2.5 models the cost to mail a package as a function of its length. To the nearest quarter inch
Anettt [7]

Answer:

Step-by-step explanation:

Set the cost equation C(l) = l3 – l2 + l + 2.5 equal to $11.00 and solve for l:

                                     C(l) = 2l + 2.5 = $11, or

If $190 is invested at an interest rate of 11% per year and is compounded continuously, how much will the investment be worth in
dangina [55]

Answer:

$295.01

Step-by-step explanation:

Using the compounding continuously formula, we are looking for A.  We have that P = 190; r = .11 (always use the decimal form of the rate!); and t = 4.  Filling in we have:

A=190e^{(.11)(4)}

Simplifying that multiplication:

A=190e^{.44}.

On your calculator, raise e to the .44 power to get

A = 190(1.552707219) and

A = $295.01

Can two obtuse angles be complementary
Norma-Jean [14]

Complementary angles are angles that add up to 90 degrees. 

Obtuse angles are greater than 90 degrees, so there's no way
to add two of them together and get a sum that's smaller than
either one already is. 

The answer to the question is 'No'.
