Answer:
C. {(1,H), (2,H), (3,H), (4,H), (1,T), (2,T), (3,T), (4,T)}
Answer:
-8
Step-by-step explanation:
First multiple the x by -4 giving -4x then multiply the same -4 by 2 giving -8
Answer:
Step-by-step explanation:
Your equation makes no sense.
I will ASSUME you mean
y = -x² - 2x + 3
which can be factored
y = (x + 3)(-x + 1)
x intercepts occur when y = 0
0 = (x + 3)(-x + 1)
which means either
x + 3 = 0
x = -3
or
-x + 1 = 0
x = 1
x intercepts are (-3, 0) and (1, 0)
The vertex will occur halfway between these point
x = (-3 + 1) / 2 = -1
so vertex = y = -(-1)² - 2(-1) + 3 = 4
(-1, 4)
Answer:
13
Step-by-step explanation:
formula: a^2 + b^2 = c^2
5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2
13 x 13 = 169
13
Yes! that is the correct answer I believe
