If you look, you can see that X is the center point for both TRAP and T'R'A'P'. I also just took the test myself and got it correct.
Hope this helps!
Answer:
C
Step-by-step explanation:
Plotting the points in a sketch quickly shows that the vertices are not at right angles to each other, thus excluding rectangle and square whose vertices are at right angles.
The best selection is a rhombus
Answer:
They will need between 2520 to 2680 pounds of cookie dough.
Step-by-step explanation:
In order to figure out how many pounds of cookie dough the math club will need, we first need to know how many pounds of dough are sold per person.
Last year, the club sold 2,080 pounds of cookie dough to 520 people, this means the amount sold to per person is:
Thus for 630 people the amount of dough needed is
and for 670 people
Thus the amount of dough the club will need is between 2520 to 2680 pounds.
The circumference is pi times the diameter of the circle. The radius is half of the diameter. In this case, the radius is then 36.
Answer:
y = (x+3)^2 -1
Step-by-step explanation:
The equation for an upward opening parabola is
y = a(x-h)^2 +k
Where (h,k) is the vertex
The vertex is (-3,-1)
y = a(x--3)^2 +-1
y = a(x+3)^2 -1
Put a point in to find a
(0,8)
8 = a(0+3)^2 -1
8 = a (3)^2 -1
Add 1 to each side
8+1 = a9
9=9a
Divide by 9
1 =a
y = (x+3)^2 -1
