Alberto spent half of his weekly

Mathematics
1 answer:
maw [93]3 years ago
6 0

Answer:

$8

Step-by-step explanation:

We can write an equation with the scenario given and solve for what we need, Alberto's weekly allowance.

Let his weekly allowance be "x"

Since he spend HALF of it, he spent 0.5x of it.

He has remaining also 0.5x of it

Now, whatever he has (0.5x), he gets $4 more from cleaning windows. After that he has:

0.5x + 4

This amount is equal to $8, so we can write:

0.5x + 4 = 8

0.5x = 8 - 4

0.5x = 4

x = 8

So, alberto's weekly allowance is $8

Find (f•g)(x) when f(x)=sqrt x+3/x and g(x)=sqrt x+3/2x
elena-14-01-66 [18.8K]
For multiplying radical expressions, we are first to list down the given.
  f(x) = (x + 3/x)^(1/2),   and
  g(x) = (x + 3/2x)^(1/2) 

We take a look at first the values of the radicands, these are the numbers inside the radical signs. Since, both of the radicands are raised to exponent 1/2, it is easy to say that we just have to multiply them and raise the product to the exponent 1/2 as well. That is,
 
(f·g)(x)  = ((x + 3/x)(x + 3/2x))^(1/2)

Simplifying,
(f·g)(x) = ((x² + 3/2 + 3 + 9/2x²)^(1/2))

Further simplification will lead us to the final answer of,
<em>(f·g)(x) = (x² + 9/2 + 9/2x²)^(1/2)</em>
