Answer:
y = (x+3)^2 -1
Step-by-step explanation:
The equation for an upward opening parabola is
y = a(x-h)^2 +k
Where (h,k) is the vertex
The vertex is (-3,-1)
y = a(x--3)^2 +-1
y = a(x+3)^2 -1
Put a point in to find a
(0,8)
8 = a(0+3)^2 -1
8 = a (3)^2 -1
Add 1 to each side
8+1 = a9
9=9a
Divide by 9
1 =a
y = (x+3)^2 -1
Answer:
not my work but hope it helps
Step-by-step explanation:
and it works out gl bestiee
It has to have an average of 10 feet per minute for 5 minutes, which means in five minutes the total of feet would have to be 50.
So you would add all these numbers up and you would get 38.
50 - 38 = 12 so the answer is 12ft
X<12
<span>5(x+5)<85 </span>
<span>5(x + 5)/5 < 85/5 </span>
<span>x + 5 < 17 </span>
<span>x + 5 - 5 < 17 - 5</span>
Answer:
c
Step-by-step explanation:
c=2*22/7r
440=44/7r
440*7/44=r
70=r
d=2r
d=2*70
d=140 cm
