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.
-15 because there is ten before 25
Answer:
Step-by-step explanation:
1) y intercept is 0
2) y intercept is 1
3) y intercept is -4
4) y intercept is 4
5) y intercept is 5
6) y intercept is 0
7) y intercept is 5
8) y intercept is 4
Yes, indeed it does equal a whole number. 45/5 equals 9, which is a whole number. Whole numbers are numbers that you count up from and including 0 (0,1,2,3,4,5,6...)
You get 9 because 45/5 is the same as 45 divided by 5 which is 9.
(πrθ)/180 = arc length [r=radius, θ=central angle, π≈3.14] ⇒
πrθ = 180*arc length
θ = (180*arc length)/πr
θ = (180 * 50)/(3.14 * 36) ≈ 79.6°
