Answer:

 t = 0 and t = 2

Step-by-step explanation:

It is at rest when the velocity = 0

The velocity is the 1st derivative

So, x'(t) = 3t^2 - 6t = 0

                3t(t - 2) = 0

                  t = 0 and t = 2

4 games so
\frac{score1+score2+score3+score4}{4}  \geq 225
score1=192
score2=214
score3=250
score4=?
so
\frac{192+214+250+?}{4}  \geq 225
\frac{656+?}{4}  \geq 225
times both sides by 4 to clear fraction
656+?≥900
minus 656 from both sides

PLZ HELP ASAP CONGRUENCE GEOMETRY
RoseWind [281]
The answer is 80 degrees. As you can see, the triangle is an isosceles triangle and both sides of the triangle equal 14. If both of the sides are congruent then the opposite angles are also congruent as well. Which means the 50 degrees in the left angle is congruent to the right angle, 50. Since triangles add up to 180 degrees, the answer for x would be 80. 

Hope this helped :)
