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
2x+4x-4=80
6x-4=80
6x=84
84/6=14
Angle c = 4 x 14= 56 - 4 = 52
Hope this helps.
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. This gives you such reflection rule:
From the diagram:
L(3,1), M(4,3), N(5,3) and P(4,1).
Using the reflection rule, you can find coordinates of image points:
L'(1,3), M'(3,4), N'(3,5) and P'(1,4).
As you can see, these are coordinates of vertices of the figure C.
Answer: correct choice is option 3 - figure C.
The applicable relation between force, mass, and acceleration is ...
... F = <em>m</em>a
Fill in the given values and solve for the mass.
... 0.75 N = <em>m</em>·3 m/s²
... (0.75 kg·m/s)/(3 m/s²) = <em>m</em> = 0.25 kg
The mass of the ball is 0.25 kg.
V(cylinder) = base*height =(πr²)h = π*4²*6=96π
Answer: B. 96π units³.
