Stuck Right now, Help would be appreciated :)
Vera_Pavlovna [14]

Answer:

C. c = (xv - x) / (v - 1).

Step-by-step explanation:

v = (x + c) / (x - c)

(x - c) * v = x + c

vx - vc = x + c

-vc - c = x - vx

vc + c = -x + vx

c(v + 1) = -x + vx

c = (-x + vx) / (v + 1)

c = (-x + xv) / (v + 1)

c = (xv - x) / (v + 1)

So, the answer should be C. c = (xv - x) / (v + 1).

Hope this helps!

What is the expanded form of the expression ∑i=04i4? 04+14+24+34 14+24+34+44 02+42 04+14+24+34+44
dimulka [17.4K]

The expression is an illustration of the summation notation

The expanded form of the summation notation \sum\limits^{4}_{i = 0} i^4 is  0^4 + 1^4 + 2^4 + 3^4+4^4

<h3>How to determine the expanded form</h3>

The summation notation is given as:

\sum\limits^{4}_{i = 0} i^4

The above summation notation represents the sum of the numbers raise to the power of 4, from 0 to 4

So, we have:

\sum\limits^{4}_{i = 0} i^4 = 0^4 + 1^4 + 2^4 + 3^4+4^4

Hence, the expanded form of \sum\limits^{4}_{i = 0} i^4 is  0^4 + 1^4 + 2^4 + 3^4+4^4
