What are the zeroes of f(x) = x2 − 6x + 8? (4 points) x = −4, 2 x = −4, −2 x = 4, 2 x = 4, −2

babymother [125]

Hey there! :)

Answer:

Third option. x = 2, and x = 4.

Step-by-step explanation:

Find the zeros of this quadratic equation by factoring:

f(x) = x² - 6x + 8

Becomes:

f(x) = (x - 4)(x - 2)

Set each factor equal to 0 to solve for the roots;

x - 4 = 0

x = 4

x - 2 = 0

x = 2

Therefore, the zeros of this equation are at x = 2, and x = 4.

Find the probability that a randomly

Alina [70]

Answer:

$31.8\%$

Step-by-step explanation:

The area of the circle is $A=\pi r^2=\pi(4)^2=16\pi$

The area of the triangle is $A=\frac{bh}{2}=\frac{8*4}{2}=\frac{32}{2}=16$

Hence, the probability of a randomly selected point within the circle falls in the red shaded area is $\frac{16}{16\pi}=\frac{1}{\pi}\approx0.318\approx31.8\%$

2 sides of a triangle measure 34 inches and 52 inches. What is the possible third side "x"? A.) 34 < x < 52 B.) 0 < x &

frozen [14]

Answer:

C.) 18 < x < 86

Step-by-step explanation:

triangle property: sum of any 2 sides is larger than the third side

if x <= 18 18 + 34 no larger than 54

if x >= 86 34 + 52 no larger than 86
