Answer:
All the four vertices of a quadrilateral inscribed in a circle lie on the circumference of the circle. The measure of an exterior angle is equal to the measure of the opposite interior angle.
Step-by-step explanation:
I don't get it.

when you are adding two negative numbers, the sum is basically the two numbers added together but as a negative. when added together they create a larger negative number; ex. -2 -8 = -10 which is the same as 2 + -8 = -10. when you are multiplying two negative numbers, you are really just multiplying the numbers and they come out to be a positive. a negative times a negative is a positive. ex. -5 x -5 = 25.

Question 2(Multiple Choice Worth 1 points)
(08.02 MC)
The function f(t) = 4t2 − 8t + 7 shows the height from the ground f(t), in meters, of a roller coaster car at different times t. Write f(t) in the vertex form a(x − h)2 + k, where a, h, and k are integers, and interpret the vertex of f(t).
f(t) = 4(t − 1)2 + 3; the minimum height of the roller coaster is 3 meters from the ground
f(t) = 4(t − 1)2 + 3; the minimum height of the roller coaster is 1 meter from the ground
f(t) = 4(t − 1)2 + 2; the minimum height of the roller coaster is 2 meters from the ground
f(t) = 4(t − 1)2 + 2; the minimum height of the roller coaster is 1 meter from the ground

(-4,4),(0,-2)
slope = (-2 - 4) / (0 - (-4) = -6 / 4 = -3/2
y = mx + b
slope(m) = -3/2
use either of ur points...(0,-2)...x = 0 and y = -2
now sub and find b, the y int
-2 = 0(-3/2) + b
-2 = b
so ur equation for this line is : y = -3/2x - 2
to turn it to function notation, sub in f(x) for y
f(x) = -3/2x - 2 <=== ur answer
