The equation of the parabola which has a vertex at (-2,0) is; y = x² +4x +4.
<h3>What is the equation of the parabola with vertex (-2,0)?</h3>
From the task content, it follows that the vertex of the of the parabola described by the graph in discuss is given by the point; (-2,0).
Hence, the vertex form of the equation is;
y = (x-(-2))² +0
Hence, the equation is; y = x² +4x +4.

12 to 16 should be the only one.
i looked over ti and 9/12 is also equivalent.
if you multiple by 1.5 that gets you 9/12
Answer: work is done in stretching it from 5.0in. to a length of 12.8in is 36 lb.In
Step-by-step explanation:
We know that
f(x) = kx
given that;
Natural length L = 5
x = 8.4 - 5 = 3.4
force F = 4.0 lb
f(x) = kx
we substitute
4 = k × 3.4
k = 4 / 3.4
k = 1.1764 = 20/17
Now work done from natural length to 12.8
x = 12.8 - 5 = 7.8
work done = ₀∫^7.8 f(x) dx
= ₀∫^7.8 kx dx
we substitute value of k
= ₀∫^7.8 (20/17)x dx
= 20/17 [ x²/2 ]
= 20/17 [ (7.8)²/2 - 0 ]
= 1.1764 × 30.42
= 35.786 ≈ 36 lb.In
Therefore work is done in stretching it from 5.0in. to a length of 12.8in is 36 lb.In
They would both have 145 apples altogether because you just add 120+25=145
no it is not linear because it’s a quadratic . (you will learn about quadratics in eighth grade)
