Is a proportional function f(x) = 5x linear? Why or why not? Explain with an example.
RideAnS [48]

Given two variables x and y, y is directly proportional to x (x and y vary directly, or x and y are in direct variation) if there is a non-zero constant k such that

   y = kx,

The relation is often denoted, using the ∝ symbol, as

   y ∝ x

in this case k = 5/1

Find an explicit form f(n) for each of the following arithmetic sequences (assume a is some real number and x is
insens350 [35]

Answer:

The explicit form for this sequence is f(n)=f(1)-\frac{n-1}{10} for all n\geq 1.

Step-by-step explanation:

The explicit form of an arithmetic sequence  of numbers   is given by the formula  f(n)=f(1)+(n-1)d, where  f(1)  is the first term of the sequence,  d  is the difference between two consecutive terms of the sequence, and n\geq 1.

We know that  the first four elements for the arithmetic sequence are {f(1)=\frac{1}{5},f(2)=\frac{1}{10},f(3)=0, f(4)=-\frac{1}{10}}.

To find the general formula for this problem we only need to calculate d in the above formula.

For n=2, we have

f(2)=f(1)+(2-1)d=f(1)+d

if we replace f(1)=\frac{1}{5} and f(2)=\frac{1}{10} and solve for d we obtain  

\frac{1}{10}=\frac{1}{5}+d

d=\frac{1}{10}-\frac{1}{5}=-\frac{1}{10}

Therefore the explicit form is  f(n)=f(1)-\frac{n-1}{10} for all  n\geq 1.

Answer:

v=11/5 or v=2.2

Step-by-step explanation:

The wording of this question is a little confusing but if it says what I think it does (5/3v+4=8-1/3) then this is the answer.
