Write the equation in vertex form for the parabola with focus (7, –27/4) and directrix y= – 13/4
Nataliya [291]

Answer:

x2 +8x +4y +4 = 0

4y= -x2 -8x -4y = -.25*x^2 -2x -1

a = -.25b = -2c = -1

x position of vertex:

h = -b / 2a

h = 2 / 2*-.25h = 2 / -.5h = -4

y position of vertex:

k = ah^2 + bh + ck = -.25*-4^2 + -2*-4 + -1k = -4 +8 -1k = 3

VERTEX = (-4, 3)*

x value of focus =x value of vertex = -4

y value of focus =(1 (-b^2 -4ac)) / 4a

a = -.25 b = -2 c =-1

y value = (1 (-4 -4*-.25*-1)) / 4*-.25

y value = (1 (-4 -4*-.25*-1)) / -1

y value = (1 -4 +1) / -1y value = (-2 / -1)y value = 2

focus value = (-4, 2)

Answer is the last one.

dexar [7]

Answer:

Number of instructors are 225.

Step-by-step explanation:

Given:

Total number of employees at bright mind learning = 300

Number of instructors = 75%

We have to convert this percentage and find the number.

So,

75\% can be written as \frac{75}{100}=0.75

Now 75% of 300 employees are the instructors at Bright mind learning.

Can be written as 0.75*300=225

Number of instructors at Bright mind learning =225
