Which equation is the inverse of y = 100 – x2?
y = plus-or-minus StartRoot 100 minus x EndRoot
y = 10 plus-or-minus StartRoot x EndRoot
y = 100 plus-or-minus StartRoot x EndRoot
y = plus-or-minus StartRoot x minus 100 EndRoot

answer:

  x ∈ {π/8, 3π/8}

step-by-step explanation:

there are two of them. they lie at the zero-crossings of the function, where

  4x = π ± π/2

  x = π/4 ± π/8 = π/8 or 3π/8

i think the answer is 1.125 or 1.13

answer: total gross profit is $ 2791

step-by-step explanation:

since, the total revenue by sales = $ 9,489,

total returned = $ 225

cost of goods = $ 5481,

and, operating expenses = $ 992

thus, the gross profit = total revenue - direct costs of producing that good or service = 9489 - ( 225 + 5481 + 992) = $ 2791

therefore, there was a gross profit of $ 2791 on the sale.
