Consider Circle Y with radius 4 m and m angle XYZ = 80 degrees

What is the approximate length of minor arc XZ? Round to the nearest tenth of a meter.

a. 3.7 m

b. 2.8 m

c. 5.6 m

d. 11.2 m

PLEASE HURRY :)

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

Use mathematical induction to prove the statement is true for all positive integers n, or show why it is false. 1^2 + 4^2 + 7^2 + + (3n - 2)^2 = [n(6n^2-3n-1)/2]

Me i'm timed right now! a. (0,-5)b. (0,-3)c. (0,3) d. (0,5)
