Part A - 226.865 or 226.87
Part B - 120
Part C - 106.865
Ummm ... idk and ehhem what is the questions in this anyway
Answer:
f(x) = 3(x - 2)² + 4
OR
f(x) = 3x² - 12x + 16
Step-by-step explanation:
Vertex form of a parabola:
Standard form of a parabola:
Let's find the vertex of this parabola.
In order to find the a-value (vertex form), let's use another point besides the vertex on the parabola.
Using (3, 7) for (x, y), let's substitute this point and the vertex (2, 4) for (h, k) into the vertex form equation and solve for a.
Simplify using PEMDAS.
Subtract 4 from both sides.
Now we have (h, k) and a of the vertex form.
- y = a(x - h)² + k → y = 3(x - 2)² + 4
In order to convert from vertex to standard form, simplify the equation by FOILing.
Distribute 3 inside the parentheses.
Combine like terms.
Therefore, we have the answer:
<u>Vertex form:</u>
<u>Standard form:</u>
4,8,12,16
this is an arithmetic sequence with a common difference of 4. This means u have to add 4 to each term to find the next number
an = a1 + (n - 1) * d
a1 = first term = 4
d = common difference = 4
so ur formula is : an = 4 + (n - 1) * 4 <==
