Question

PLEASE HELP!! Research suggests that the probability of a certain fuse malfunctioning increases exponentially as the concentration of an impurity in the fuse increases. The probability is modeled by the function y = 5(257,945)x, where x is the impurity concentration, and y, given as a percent, is the probability of the fuse malfunctioning. Find the probability of the fuse malfunctioning for an impurity concentration of 0.17. Round to the nearest percent.

Answer 1

Is x an exponent?

Answer 2

\(\Large y = 5(257945)^x\)

Answer 3

If so, just replace x by the value they give you, 0.17
Use a calculator to raise 257945 to the 0.17 power, and multiply by 5.
Then round to the nearest whole number.

Answer 4

oh okay I understand

Answer 5

Great.
