Two real solutions of tx^2+3x_7=0
Olegator [25]

The number of solutions of a quadratic equation

ax^2+bx+c=0

Depends on its discriminant

/Delta=b^2-4ac

If /Delta>0 there are two distinct solutions

If /Delta=0 there are two coincident solutions

If /Delta<0 there are no solutions.

We know that there are two real solutions (I assume you mean distinct solutions), so we know that the discriminant is positive:

Elodia [21]

Answer:

The correct answer is (c) the poll uses voluntary response, so the results tell us little about the population of all adults.

Step-by-step explanation:

You can't conclude (a) because this question hasn't be made to all the Americans.  

You can't conclude (b) because the poll doesn't use any convenience for the selection of the sample

You can't conclude (d) because this is not a poll with a premeditated sample, therefore, the size is inconclusive.  

You can conclude (c) because the poll was available for anyone who voluntary wanted to answer it.

Zeus Industries bought a computer for $2207. It is expected to depreciate at a rate of 27% per year. What will the value of the
vodka [1.7K]
Multiply 2207 by .27 and get $595.89.  This is the first year depreciation.
After 1 year the computer has a value of $1611.11.
Year 2 depreciation would be 1611.11 X .27= $434
1611.11-434= $1,177.11
Year 3  1177.11 X .27= $317.82
1177.11- 317.82= $859.29
Final year 859.29 X .27= 232
$859.29- 232= $627.29
