Answer:
Mean and Median
Step-by-step explanation:
Find the vertex: -4x^2 + 16x - 7
Vertex = ( x, f(x)).
x = -b/2a
x = -16/2(-4)
x = -16/-8
x = 2
f(x) = -4x^2 + 16x - 7
Let x = 2
f(2) = -4(2)^2 + 16(2) - 7
f(2) = -4(4) + 32 - 7
f(2) = -16 + 32 - 7
f(2) = 16 - 7
f(2) = 9
Vertex = (2, 9)
Answer:

Step-by-step explanation:
easy
Answer:
It is an acute triangle because all the angles are less than 90 degrees.
R - 4.5 < 11
