Answer:
A. Segment AB congruent segment CD
C. Segment AD congruent segment BC
Step-by-step explanation:
These are both true because a characteristic of a rhombus is that all four sides are congruent. Therefore we must prove that AB is congruent to CD and AD is congruent to BC.

Option (B) is correct.
The sequence that best defines the function is f(1) = 7, f(n + 1) = f(n) - 3; for n ≥ 1
Step-by-step explanation:
Given sequence 7 ,4, 1,-2
We have to choose a function from given options that best defines this sequence.
Let f(n) denotes the value at nth position,
Like f(1) = 7 , so here, n= 1.
Since next term is 4 = f(2)
4 can be written as 7 - 3 = f(1) -3
Next term is 1 = f(3)
1 can be written as 4-1 = f(2) - 3
Next term is -2 = f(4)
-2 can be written as 1-3 = f(3) - 3
Thus, following the sequence and writing in general form for n
f(n+1) = f (n) -3 , n ≥ 1
Thus, option (B) is correct.
The sequence that best defines the function is f(1) = 7, f(n + 1) = f(n) - 3; for n ≥ 1
f(1) = 7
f(2) = 7 -3 = 4
f(3) = 4 -3 = 1
f(4) = 1 -3 = -2

1.Since 5 is less than 8, borrow 1 from the next column to make 15.
2.Calculate 15 - 8, which is 7.
3.Calculate 3 - 3, which is 0.
4.Since 2 is less than 5, borrow 1 from the next column to make 12.
5.Calculate 12 - 5, which is 7.

Determine the dance committee's greatest possible revenue. (Please show work as in #'s)
What ticket price will produce the greatest revenue? (Please show work as in #'s)
Answers
the number of $0.10 increases we make will be called t. so:
price of ticket = $4 + $0.10t
tickets sold = 300 - 5t
R = (4 + .10t)(300 - 5t)
R = 1200 + 10t - .5t^2
R = -1/2t^2 + 10t + 1200
to find the maximum, we have to find the roots of this function.
0 = -1/2t^2 + 10t + 1200
0 = -t^2 + 20t + 2400
0 = t^2 - 20t - 2400
quadratic formula
t = 20 +- sqrt((-20)^2 - 4(1)(-2400)) all over 2(1)
t = 20+-sqrt(400+9600) all over 2
t = 20+-sqrt(10000) all over 2
t = 20+-100 all over 2
t = -80/2 or t=120/2
t = -40 or 60
now find the average of these roots. this will find the "middle" of the parabola, which is where the vertex (maximum) will be.
-40 + 60 all over 2
20/2
10
the vertex is at t=10. plug this into the formula:
R = -1/2t^2 + 10t + 1200
R = -1/2(10)^2 + 10(10) + 1200
R = 50 + 100 + 1200
R = 1350
therefore, the number of 10 cent price increases should be 10, because that will lead to total profits of $1350, the maximum possible. the ticket price will be $5.
