Find the number of real zeros of
Amiraneli [1.4K]

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

After being hit, the puck travels along the ice at a constant speed. What might cause his motion to change?
Firdavs [7]

Answer:

<em>Hi! Todo here!! UwU</em>

Step-by-step explanation:

Even if the puck is on ice, I wouldn't automatically assume no friction. Otherwise hockey pucks could be tapped slightly and potentially go across entire arenas. I'd say include at least a small friction force opposing motion.

<em>Hope This Helps!!!</em>
