Which of the following
numbers does NOT have the
same value as one-eighth?

B. 1.25

Step-by-step explanation:

Convert the mixed number by placing the numbers to the right of the decimal over 100. Reduce the fraction. Then convert the mixed number to an improper fraction by multiplying the denominator by the whole number and adding the numerator to get the new numerator, place the new numerator over the old numerator and you get 5/4 which is not equivalent to 1/8

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
