Answer:
y= 8(x-5)² + 6
Step-by-step explanation:
Parabolas have two equation forms, namely; the standard and vertex form.
In the vertex form, y = a(x - h)² + k, the variables h and k are the coordinates of the parabola's vertex.
In this case; a=8, h =5, and k=6
Therefore;
The vertex equation will be
y= 8(x-5)² + 6
Answer:
7/8
Step-by-step explanation:
0.875 = 875/1000
875/1000 Divide numerator and denominator by 125
7/8
9-b when b=8
9 -8 =1
9-b when b=-8
9 - (-8)
9+8
17
I'm not sure whether you meant b=8 or b=-8
Answer:
Step-by-step explanation:
No, because Bernie had to run 9 meters 7.77777778 time (70/9) and each of those 9-meter sections took 4 seconds, so her time was 31.1111111 (7.77777778*4). While Wendel had to run 61 meters 70-his headstart (9 meters) (70-9). So he only had to run 30.5 blocks of 2 meters (61/2). And since they're only 1 second long, it's 30.5*1=30.5.
So the answer is a NO because (Bernie) 31.1111111 seconds > 30.5 seconds (Wendel).
