A). The function is increasing where its derivative is positive.
Its derivative is positive from 2 to 6, and from 8 to 10.
B). The function is decreasing where its derivative is negative.
Its derivative is negative from 0 to 2, and from 6 to 8.
C). The function has a relative minimum where its derivative is zero
and changing from negative to positive.
Its derivative is zero and changing from negative to positive at 2 and 8.
D). The function has a relative maximum where its derivative is zero
and changing from positive to negative.
Its derivative is zero and changing from positive to negative at 6 and 10.
E). The function is concave up between consecutive relative maxima.
The interval between consecutive relative maxima is 6 < x < 10 .
F). The function is concave down between consecutive relative minima.
The interval between consecutive relative minima is 2< x < 8 .
G). The function has points of inflection where its second derivative is
zero, that is, where its first derivative is a relative minimum or a relative
maximum.
Its first derivative is a relative minimum or maximum at x = 0, 4, 7, and 9 .
H). Good luck on the sketch !
The quadrilateral ABCD, with vertices <span>A(-2,3), B(9,3), C(5,6) and D(2, 6), is a trapezoid.
By definition, a trapezoid is a quadrilateral which has two parallel sides (These are called "bases"), but the other sides are not parallels. </span>
I believe it would be C, if I'm not mistaken.1 yard = 3 feet
You'd have to divide by yards
4.6 yards = 3 feet = 13.8 feet
yard
Sorry if this doesn't help

Answer:
The probability of picking at least three boys is 
.
Step-by-step explanation:
We have to choose 5 people to form a student government.
We have to pick 5 people out of 7 girls and 5 boys.
What is the probability that at least 3 boys are a part of the student government?
The probability of picking 5 people out of 12 girls and boys = 
The probability of picking at least 3 boys excludes the probability of picking 3 girls. The probability of picking 3 girls = 
The probability of picking at least 3 boys = 1 - = 
The probability of picking 5 people and the probability of picking at least 3 boys = × =
