Hi
AB is a diameter so radius of circle is 24/2 = 12
Now AC = 2π *12 * (150/360) ≈ 31.42
when you multiply sum by a number like (7+9)plus 5 it is the same as multiplying each added by that factor (7time5)plus (9time5)
Answer:
{f|0 ≤ f(x)}; x² - 4x + 5
Step-by-step explanation:
To find the Quadratic Equation, plug the <em>vertex</em> into the Vertex Equation FIRST, <em>y = </em><em>a</em><em>(</em><em>x</em><em> </em><em>-</em><em> </em><em>h</em><em>)</em><em>²</em><em> </em><em>+</em><em> </em><em>k</em>, where (<em>h</em><em>,</em><em> </em><em>k</em>) → (<em>2,</em><em> </em><em>1</em>)<em> </em>is the vertex, plus, -h gives you the OPPOSITE terms of what they really are, and k gives you the EXACT terms of what they really are: (x - 2)² + 1. Doing this will give you the Quadratic Equation of <em>x² - 4x + 5</em>. You understand now?
I am joyous to assist you anytime.
Question 11 is C and also question 2 is A
Blue 9 x 3 = 27
red 3 x 3 = 9
27 + 9 = 36
I hope this helps
