Belkin co. provides medical care and insurance benefits to its retirees. in the current year, belkin agrees to contribute 5% of the employees’ $250,000 gross salaries to a retirement program. what is the amount of employee benefits expense for the current period?

113.1

step-by-step explanation:

v=4

3πr3=4

3·π·33≈113.09734

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain

choice b

step-by-step explanation:

f(x) = 88x^2 -264x + 300

the line of symmetry of a parabola is defined by

h = -b/2a

where ax^2 +bx+c=0

so

h = - -264/ (2*88)

h = 3/2

so x = 1.5
