Focus of the parabola is (-5,5) and directrix is y = -1.
Let's assume a point (x,y) on parabola.
According to definition of parabola, the distance between point (x,y) and focus (-5,5) would be same as the distance between the point (x,y) and directrix y = -1.
Hence, option D is correct, i.e. f(x) = one twelfth (x + 5)2 + 2.
Answer:
Linear
Step-by-step explanation:
If it were exponential it would have a small number one the right of the x
4 1/2 = 9/2
5/9 x 9/2 = 45/18
Answer:
(-1.5, 3.275)
Step-by-step explanation:
midpoint = ( x1+X2/2 , y1+y2/2)
=(0+(-3)/2, 0.55+6/2)
=( -3/2, 6.55/2)
=( -1.5, 3.275)
Answer:
#4.
- 3 < - 2 1/2
If you consider the number line, the numbers increase from left to right. The number on the left is smaller than a number on the right.
- 3 is smaller than -2 1/2, it means -3 is on the left from the -2 1/2 on the number line.
#5.
Jada's score is positive, it means the number reflecting the score is to the right from zero on the number line.
Isabel's score is negative, it means the number reflecting the score is to the left from zero on the number line.
Since Isabel's score is to the left from the Jada's score, she has lower score than Jada.
With the lowest score, Isabel is the winner.
