A small company that manufactures snowboards uses the relation P=162x-81x^2 to model its profit. In this model, x represents the number of snowboards in thousands, and p represents the profit in thousands of dollars. How many snowboards must be produced for the company to break even?

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
