Answer:
<em>d) The equation of the standard parabola</em>
<em> x² = 6 y</em>
Step-by-step explanation:
The given directrix is y= -31.5
The equation of the parabola is of the form x² =4 a y
Given focus (0,1.5) , Here a= 1.5
The equation of the standard parabola
x² = 4 a y
x² = 4 (1.5)y
x² = 6 y
<u><em>Conclusion</em></u>:-
<em>The equation of the standard parabola</em>
<em> x² = 6 y</em>
2 1/4
Explanation-
1/2+1/2=2/2-------1 Whole
1/4+1/4=2/4
1+2/4= 1 2/4
3/4+ 1 2/4= 1 5/4= 2 1/4
Answer:
z = 92
x = 11
Step-by-step explanation:
From the figure,
13x - 55 = 88 (Opposite angles made by two straight lines are equal)
13x = 88 + 55
13x = 143
x = 143/13
x = 11
Again,
88 + z = 180 (Sum of angles of a straight line)
z = 180 - 88
z = 92
