Step-by-step explanation:
Since they are consecutive terms in an AP,
(1 - x) + (2x + 1) = 2(x + 3).
=> x + 2 = 2x + 6
=> x = -4.
Therefore the terms are 5, -1 and -7.
=> Common difference = -6.
F(t)
= t2 + 4t − 14
y + 14 + 4 = (
t2 + 4t +4)
y + 18 = ( t +
2)^2
so the vertex
of the parabola is ( -2 , -18)
<span>the axis of
symmetry is y = -18</span>
Answer:
Hello! answer: 28.26
Step-by-step explanation:
You find circumfrence by doing diameter × pi or
radius × 2 × pi since we have are diameter this shall be a breeze 9 × 3.14 = 28.26 therefore the circumfrence is 28.26 hope that helps!
Answer:
Pv/rt=n
Step-by-step explanation:
Pv=nrt
divide both sides by rt
Pv/rt=n
