The Answer to your question ∑ (2k -10) from 3 to k=6 is -4
begin by pulling 2 out of the numerator using the distributive property.
numerator: 2(16x^4 - 25) and now factor
numerator: 2(4x^2 - 5)(4x^2 + 5)
Now go to the denominator. It looks messy but it will break down.
Pull out 4x^2 for the first two terms and 5 for the last 2 terms. Use the distributive property.
denominator: 4x^2(x - 3) - 5(x - 3) now x - 3 is the common term.
denominator: (x - 3)(4x^2 - 5)
Put the two results together.
After canceling out 4x^2 - 5 on both the numerator and the denominator, you are left with.

<h3>How to graph the function?</h3>
The equation of the cosine function is given as:
f(x) = cos(x) - 3
The above function is a cosine function, and the parent function of the cosine function is
f(x) = cos(x)
This means that the function f(x) = cos(x) is translated 3 units down to get the function f(x) = cos(x) -3
Next, we plot the graph of the function f(x) = cos(x) - 3

Answer:
3
Step-by-step explanation:
To find the average add all these numbers together, then divide by how many numbers you have.



Answer:
y = (x - 3)²
Step-by-step explanation:
The vertex of the general equation of the parabola of the form:
y = (x - h)² + k
is at (h, k)
We are given that the vertex is at the point (3, 0)
This means, h = 3 and k = 0
Using these values in the first equation, we get:
y = (x - 3)² + 0
y = (x - 3)²
Therefore, 1st option gives the parabola with vertex at (3, 0)
