The cost of sending an overnight package from Los Angeles to Miami is $26.30 for a package weighing up to but not including 1 po
und and $4.00 for each additional pound or portion of a pound. A model for the total cost C (in dollars) of sending the package is С = 26.30 + 4.00[[x]], x > 0, where x is the weight in pounds.

Answer:
The answer is shown in the pic.
Step-by-step explanation:
The cost model will have a fixed cost of $26.30 for 0 ≤ x ≤ 1 lb and variable cost of $4.00/lb for x > 1.
As seen on the pic, the graph will be that of the greatest integer function that is vertically stretched by a factor 4.00 & shifted 26.30 units upward.

Answer:
<h2>168 ft²</h2>Step-by-step explanation:
the surface area of the triangular prism =
2×(the base’s area) + the lateral area
the base’s area =
the lateral area =
9×(6 + 5 + 5) = 9×16 = 9×16 = 144
finally,
the surface area of the triangular prism = 24 + 144 = 168
