Answer:
(y - 3 )² = 8 ( x - 4 )
The given vertex of Parabola is ( 4 , 3)
And Directrix is X = 6
The equation of parabola is
( y - k )² = - 4 ( P) ( x - h )
Now p = 4 - x = 4 - 6 = - 2
And given value of ( k , h) = ( 4 , 3)
Or ( y - 3 )² = - 4 ( - 2) ( x - 4 )
Or, ( y - 3 )² = 8 ( x - 4 )
Hence The equation of parabola with directrix x = 6 And
vertex ( 4 , 3 ) is ( y - 3 )² = 8 ( x - 4 ) Answer
The answer is D because the additional 120 for the remaining six months only brings them to 9900. An additional month brings them to a total of 9690.
The smallest angle would be 19 degrees. So option D is correct.
<h3>What is the sum of the octagon?</h3>
The sum of exterior angles of the regular octagon is 360 degrees.
Given;
The angles
x + 13 + 2x - 1 + 2x + 6 + 2x + 12 + 2x - 17 + 3x - 4 + 3x - 10 + 4x = 360
19x - 1 = 360
19x = 359
x = 18.89
The smallest angle would be
2x - 17 = 2(18.89) - 17 = 19
