2. Find the zero(s) of the function: f(x) = (x + 1)? a) 1 and -1 b) 0 c) 2 and -2 d) -1​

ou would have 12 of each

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
