Which expression shows the sum of the polynomials with like terms grouped together? 10x^2y+2xy^2-4x^2y
Molodets [167]
<span>first find the similar term, the similar term is x^2y.
10x^2y + 2xy^2- 4x^2y
group together the similar term and place them in a parenthesis
then perform the operation to simplify the expression.

Y = f(x) = 16x Find f(x) when x = 1/2​
Alina [70]

Answer:

The answer depends on what the problem really is.

f(1/2) = 8

or

f(1/2) = 4

See below.

Step-by-step explanation:

This is the problem as it was posted:

y = f(x) = 16x

Let x = 1/2

y = f(1/2) = 16(1/2) = 8

Perhaps the problem is this:

y = f(x) = 16^x

If x is an exponent of 16 and not a factor, then the answer is:

y = f(\frac{1}{2}) = 16^\frac{1}{2} = \sqrt{16} = 4

<span>Data:

infinite geometric series

A1 = 880

r = 1 / 4

The sum of a geometric series  in sigma notation is:

 ∑ Ai = A ----------- ; where A = A1
i = 1             1-r

 When | r | < 1 the infinite sum exists and is equal to</span><span><span>:
