Let x = number of inches high the house would be on the blueprint.
6 inches/x = 11_2/3 feet/20 feet
Rewrite 11_2/3 feet as 35/3 feet.
6/x = (35/3)/20
x(35/3) = 6(20)
x(35/3) = 120
35x/3 = 120
35x = 120(3)
35x = 360
x = 360/35

Answer:
Maximum
Vertex: (0,-1)
Symmetry: x = 0
Second graph
Step-by-step explanation:
y = a(x - h)² + k
y = -2x² - 1
a = -2
h = 0
k = -1
Since a < 0, it has a maximum point
Vertex: (h,k) = (0,-1)
Symmetry: x = h
So, x = 0
Answer:
im pretty sure the answer is ∠e and ∠i; ∠f and ∠g
but if not im so sorry :(
Assuming a fair die,
probability of winning 0.25 = (2/6) = 1/3
probability of losing 0.25 = (4/6) = 2/3
Expected win
= sum (proba.*winning)
=0.25*(1/3) + (-0.25)(2/3)
=-0.25/3
= - (1/12) dollars (negative sign means expecting to lose)
A, E and D are your three answers and
