Answer:
10 miles
Step-by-step explanation:
Right triangle
a^2 + b^2 = c^2
6^2 + 8^2 = c^2
36 + 64 = c^2
Sqrt 100 = c
C = 10
(x-6.5)^2 = 60.25 is the answer
Answer:
{-2, 1, 2}
Step-by-step explanation:
F(x) = x³ - x² - 4x + 4 is factorable as follows:
F(x) = x²(x - 1) - 4(x - 1). (x - 1) is a common factor. Factor it out:
F(x) = (x - 1)(x² - 4)
x² - 4 can be factored further:
F(x) = (x - 1)(x - 2)(x + 2)
The possible roots of F(x) are {-2, 1, 2}.
