PRE CALC HELP PLEASE

True.

Step-by-step explanation:

The function is indeed a polynomial. We have the single variable plus a constant (it's irrational, but it's still simply just a constant number). This fits the definition of polynomials.

f(x) has value 150 at x= 0

and 0 at x= 3

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

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
