Answer:
-4y = x², or y = - x²/4, or y = -(1/4)x²
Step-by-step explanation:
Because the focus is beneath the directrix, this vertical parabola opens down. The general formula is 4py = x².
Because the distance between focus and directrix is 2 units, p = -1 here. The negative sign shows that the parabola opens down.
4py = x² becomes 4(-1)y = x², or -4y = x², or y = - x²/4
y/x =k
13/9 = 1.4444444
39/27=1.4444444
104/72=1.4444444
k =13/9 = 1 4/9
this is direct variation with a constant of 13/9 or 1 4/9
Answer:
x + 13 < 50
Step-by-step explanation:
Answer:
A=3
Step-by-step explanation:
so the scale factor from ABC to DEF is 1/4. so 8*1/4 is 2 which is what they give us. so 12 *1/4 would be 3. The area of DEF is 3.
