Answer:
C. f has a relative maximum at x = 1.
Step-by-step explanation:
A. False. f(x) is concave down when f"(x) is negative. f"(x) is the tangent slope of the graph, f'(x). So f(x) is concave down between x = -1.5 and x = 1.5.
B. False. f(x) is decreasing when f'(x) is negative. So f(x) is decreasing in the intervals x < -3 and 1 < x < 2.
C. True. f(x) has a relative maximum where f'(x) = 0 and changes from + to -.
Answer:
-2
Step-by-step explanation:
y=-2x+5
y=mx+b where m=slope and b=y-intercept
No, it does not seem reasonable. The quarterly statement reports an increase of $47, so it would be a positive rate of return on the investment instead of a negative rate.
Answer:
3400 workers
Step-by-step explanation:
85% of men that means 15% are women
15% = 510
15/100= 510/x
100x510=51000
51000/15 =3400
x=3400
