Answer:
1
Step-by-step explanation:
The discriminant of the quadratic equation 2x2+4x-7=0 is 1
1) A translation 2 units right
2) A reflection over the x-axis
Sin230=sin(180+50)=sin180cos50+cos180sin50=-sin50 answer 1
V=πr2h
v=π(5)^2(10)
v=250π
v=785 inches cubed
Complements are numbers that add 90. Since one is 57, the other has to add to 57. So 33 would add with 57 to get 90.
