Answer:
D: 0 and 1
Step-by-step explanation:
Function is defined by;
f(x) = 3x^(5) - 5x⁴
Now, an inflection point will be a point on the graph where the inflection or concavity changes.
Thus, let's find the derivatives until we get there;
f'(x) = 15x⁴ - 20x³
f''(x) = 60x³ - 60x²
So factorizing gives;
f''(x) = 60x²(x - 1)
At f''(x) = 0, we have; x = 0 or x = 1
Thus, the x coordinates of points of inflection are 0 & 1
-6/7 = -0.85
-31/50 = -0.62
So -0.62 is greater than -0.85
-0.62 < -0.85
Because the bigger the fraction is the less it actually is and I think the same goes for decimals . Hope I helped
C. 6.25 in
Ratios and cross multiplication:
2 inches is to 130 feet as x is to 406.25 feet
2/130 = x/406.25
(2)(406.25) = (130)(x)
812.50 = 130x
Divide both sides by 130
x = 6.25
