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>
Answer:
Brian can read 0.4 or 4/10 in 1 hour

Answer:
$713.8
Explanation:
14%of 860 = 120.4
3% of 860 = 25.8
so, subtract the sum of the above 2 values from 860.
860 - (120.4+25.8) = 860-146.2 = 713.8
Hope this helps
