On the graph of f(x) = sin x and the interval (-2pi,0), for what value of x does f(x) achieve a minimum? Choose all
answers that apply.

x = -pi/2

Step-by-step explanation:

hello :

f(x)=sin x     x⋲(-2pi,0)

the derivate for f is : f'(x) = cosx

f(x) achieve a minimum when : f'(x) =0

cosx = 0  genral solution is :

x = pi/2 +kpi    .. k in Z

but :  x⋲(-2pi,0) so : x = -pi/2(k = -1)

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

if you need , reply with more info. u.
