What are the coordinates of the vertex of the parabola described by the equation below ? y=-7(x-4)2-5

Answer with explanation:

Equation of Parabola is

y=-7(x-4)²-5

y+5= -7(x-4)²

To find the vertex of parabola, we will substitute

y +5 =0

→y=-5

And, x-4=0

→ x=4

So, vertex of parabola is = (4,-5)

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
