Answer:
hello your question lacks some information below is the complete question
Suppose you are designing a cardboard box that must have a volume of 27 cubic feet. The cost of the cardboard is $0.15 per square foot. What is the most economical design for the box (one that minimizes the cost), and how much will the material in each box cost?
Answer : Box design , $8.1 ( cost of material in each box)
Step-by-step explanation:
Volume of cardboard box = 27 cubic feet
cost of cardboard = $0.15 square feet
i) The most economical design for the box would be Designing a square box because the dimensions of the box would be
= 3 ft
ii) The cost of the material for each box can be calculated as
= surfaces * surface area * cost per square foot
= 6 * 3^2 * $0.15
= $8.1
Answer:
( 3 - 7i) • ( 2 - 5i) = ( - 29 - 29i)
Step-by-step explanation:
The formula is :
(a+bi) • (x+yi) = ax+by•i^2+(ay+bx)i
and since i^2 = -1 it can be written as :
ax - by + (ay + bx) i
( 3 - 7i) • ( 2 - 5i) =
( - 29 - 29i)
