For 20

the expression 0.01e + 0.003e2 gives the thickness in millimeters (mm) of the insulation needed for a high voltage cable. e is the number of kilovolts carried by the cable. what thickness of insulation material is needed for 5 kilovolt cable?

0.265 mm

0.325 mm

0.8 mm

0.125 mm

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.

i would say c is the best answer, hope it's right!

good luck! =)
