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
If Dave earns $150/week times 4 weeks = 600
3.8% commission on $4175.68 is $158.68
$600 + $158.68 = $758.68 for the month of February
Answer:

Step-by-step explanation:
The formula of an area of a kite:

p, q - diagonals
We have p = 17 and q = 15.3. Substitute:

Answer:4:5xn
Step-by-step explanation:
You can use any ratio just times 4:5 by any number then you'll get a ratio equivalent to 4:5
The 2 angles given are vertical angles, which mean they are the same.
So we have: 3x +1 = 64
Subtract 1 from each side:
3x = 63
Divide both sides by 3:
X = 63 / 3
X = 21
The answer is A.
