On interval 0 ≤ x < 2π, where are the x-intercepts of y = cos(2x)? A. pi/2 and 3pi/2
B. 0, pi, and 2pi
C. pi/2, pi, and 3pi/2
D. pi/2, 3pi/4, 5pi/4, and 7pi/4

i think it is d

Step-by-step explanation:

we need the options

step-by-step explanation:

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
