kvasek [131]3 years ago
3 0

Answer:

A

Step-by-step explanation:

Discriminant is given by

D = b^{2} -4ac

If it is negative then in quadratic formula the square root part becomes negative which makes the solution complex.

Misha Larkins [42]

Answer:

x=0

Step-by-step explanation:

13x-2 = 10x-2

Subtract 10x from each side

13x-10x-2 = 10x-2 -10x

3x-2 = -2

Add 2 for each side

3x-2+2 = -2+2

3x= 0

divide by 3

3x/3 = 0/3

x =0

1 gallon 2 quarts 3 pints of orange juice
1 gallon 3 quarts 7 pints of pineapple juice and
1 gallon 3 <span> quarts 3 pints of ginger ale

that's:

3 gallons 8 quarts and 13 pints.

2 pints make a quart, so 13 pints make 6 quarts and 1 pint, so actually it's:

</span><span>3 gallons 8+6=14 quarts and 1 pint.
4 quarts are a gallon, and 14 quarts are 3 gallons 2 quarts, so the final answer is:

</span>
<span>3+3=6 gallons 2 quarts and 1 pint. </span>

alexgriva [62]

Answer:

The number of ways is  \left n} \atop {}} \right. P_r  =  336

Step-by-step explanation:

From the question we are told that

   The number of tickets are   n = 8

    The number of finalist are r   =3

Generally the number of way by which this winners can be drawn and arrange in the order of   1^{st} , \  2nd ,  \  3rd    is mathematically represented as

             \left n} \atop {}} \right. P_r  =  \frac{n\ !}{(n-r) !}

substituting values

             \left n} \atop {}} \right. P_r  =  \frac{ 8!}{(8-3) !}

           \left n} \atop {}} \right. P_r  =  \frac{ 8* 7*6*5*4*3*2*1}{ 5*4*3*2*1}

           \left n} \atop {}} \right. P_r  =  336
