The terminal side of angle lies in Quadrant III and the terminal side of angle lies in Quadrant IV. If tan a = 4/9 and cot β = −2/7 , find the EXACT value of

sin ( a−b ) .

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

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
