THE ANSWER IS 2
A) The signs of the first derivative (g') tell you the graph increases as you go left from x=4 and as you go right from x=-2. Since g(4) < g(-2), one absolute extreme is (4, g(4)) = (4, 1).
The sign of the first derivative changes at x=0, at which point the slope is undefined (the curve is vertical). The curve approaches +∞ at x=0 both from the left and from the right, so the other absolute extreme is (0, +∞).
b) The second derivative (g'') changes sign at x=2, so there is a point of inflection there.
c) There is a vertical asymptote at x=0 and a flat spot at x=2. The curve goes through the points (-2, 5) and (4, 1), is increasing to the left of x=0 and non-increasing to the right of x=0. The curve is concave upward on [-2, 0) and (0, 2) and concave downward on (2, 4]. A possible graph is shown, along with the first and second derivatives.
You use pemdas and they both equal to 77. So yes they are equivalent.
Answer:
Step-by-step explanation:
Let c represent Chanda's age now. In six years, the Sokhem's age will be 2c. At that time, the sum of their ages is ...
(c+6) +2c = 60
3c = 54 . . . . . . . . subtract 6, collect terms
c = 18 . . . . . . . . . . divide by 3
Chanda is 18, Sokhem is 30.
_____
<em>Check</em>
In 6 years Chanda will be 24, Sokhem will be 36. The sum of their ages then will be 24+36 = 60. Since Chanda is 18 now, Sokhem's age then will be 2 times Chanda's age now.
