Cecilia traveled to canada and bought a new lamp for 460 canadian dollars. if the canadian dollar is worth $.8817 against the u. s. dollar, how much would the same lamp cost in the united states? (round to the nearest cent.) a. $405.58 b. $517.77 c. $577.25 d. $480.66

Option A.

Step-by-step explanation:

Cecilia traveled to Canada and bought a new lamp.

She paid for the lamp = 460 Canadian dollars

1 Canadian dollars = 0.887 U.S. dollar

So we will multiply 460 Canadian dollars to the value of a Canadian dollars in U.S.

The same lamp cost in the United States = 460 × 0.887

                                                                    = 405.582 ≈ 405.58

The cost of the same lamp in United States would be $405.58.

Option A. is the answer.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years

step-by-step explanation:

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
