I’m pretty sure it’s line graph, if not that, bar graph
Hope this helps :D
To answer this, we need to see the polynomial. Descending order is in a way that the first term of the polynomial will be three, the second (in descending order, two....and so on).
420t+20t3-210t2
In descending order is:
20t^3 - 210t^2 + 420t
So, the option is number two.
A full circle is 360°.
x + 3x + 90° = 360°
4x = 360° - 90°
4x = 270°
4x/4 = 270°/4
x = 67.5°
Hope it helps! Make me brainliest if it’s correct.
