Answer:
B
Step-by-step explanation:
Using the determinant to determine the type of zeros
Given
f(x) = ax² + bx + c ( a ≠ 0 ) ← in standard form, then the discriminant is
Δ = b² - 4ac
• If b² - 4ac > 0 then 2 real and distinct zeros
• If b² - 4ac = 0 then 2 real and equal zeros
• If b² - 4ac < 0 then 2 complex zeros
Given
f(x) = (x - 1)² + 1 ← expand factor and simplify
= x² - 2x + 1 + 1
= x² - 2x + 2 ← in standard form
with a = 1, b = - 2, c = 2, then
b² - 4ac = (- 2)² - (4 × 1 × 2) = 4 - 8 = - 4
Since b² - 4ac < 0 then the zeros are complex
Thus P(x) has no real zeros
5(2x-7)

Answer: The length of each side of the building block is 0.56 feet
Step-by-step explanation:
A company is making building blocks. Each building block is a cube and has volume 125/729 ft cubed . Each of the building blocks has 6 faces which are squares, 8 vertices and 12 edges.
Since a square has all sides to be equal sides,
The volume of the cube = the volume of the building block =
Product of length,L, width, W and height, H.
Volume of the building block = L × W × H
Since length = width = height,
Volume of cube = L^3
From the information given,
Volume of a building block = 125/729ft cubed
L^3 = 125 / 729
Taking cube root of both sides of the equation,
L = cube root of 125/729
L = 5/9
= 0.56 feet
