ANSWER

The discriminant is

D. 49

EXPLANATION

The given equation is

0 = 2 {x}^{2}  + 3x - 5
We can rewrite this as,


2 {x}^{2}  + 3x - 5 = 0

When we compare this to the general quadratic equation, we obtain;


a=2,b=3,c=-5

The discriminant is given by,

D =  {b}^{2}-4ac

We substitute the values to obtain,


D =  {3}^{2}-4(2)( - 5)

D =  9 + 40

We simplify to get,

D = 49

Hence the correct answer is D.

If postage costs $.54 for the first ounce and $.22 for the each additional ounce, calculate the cost of mailing a 10- ounce enve
sweet-ann [11.9K]

Answer:

Hence, the total cost of mailing 10 ounces is:

$ 2.52

Step-by-step explanation:

If postage costs $.54 for the first ounce and $.22 for the each additional ounce.

i.e. cost of first ounce=$ 0.54.

Now let x denote the number of ounces after the first ounce,

Hence, the cost of x ounces=$ (0.22×x)=$ 0.22 x

Hence, the cost of mailing (x+1) ounces is: $ (0.54+0.22 x)

Now, we have to find the cost of  mailing a 10- ounce envelope.

i.e. after the first ounce we need 9 more ounces.

Hence, the total cost of mailing is calculated as:

=$ (0.54+0.22\times 9)\\\\=$ (0.54+1.98)\\\\=$ 2.52\\

Hence, cost of mailing 10 ounces is:

$ 2.52
