SECTION B Application of your knowledge on the nature of roots:
1.
Prove that the roots of x² + (1 - k) x +k - 3 = 0 are real for all real values of k.​

the answer is 99.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches

160 cm

step-by-step explanation:

you have to add all the sides together
