68% x 12 = 8.16
Multiply 68% by 12 to get answer
Answer:
91in^2
Step-by-step explanation:
SA of base = 7x7 = 49in^2
SA of each triangle = 1/2 x 7 x 3 = 10.5in^2
SA of all 4 triangles = 10.5 x 4 = 42in^2
SA Total = 49 + 42.= 91inch^2
Answer:
<em>Equation of the parabola x² = -12.56 y</em>
Step-by-step explanation:
<u>Explanation</u>:-
<em>Given Y- intercept ( 0, -3.14)</em>
<em>Given Focus is ( 0 , -a) = ( 0, -3.14)</em>
<em>So a = 3.14 center C(0,0)</em>
<em>The graph of the parabola is downwards and the axis of the parabola is Y-axis.</em>
<em>Equation of the standard parabola x² = -4 a y</em>
<em> x² = -4 (3.14) y</em>
<em> x² = - 12.56 y</em>
<u><em>Conclusion</em></u><em>:-</em>
<em>Equation of the parabola x² = -12.56 y</em>
Basing on the description, a parabola opening up with vertex at origin, the formula with vertex at origin is used, x^2 = 4py. p is the focus and so with the dimensions given, we obtain a 0.25 and that is the distance of the focus to the vertex.
