What is the discriminant of f(x)=2x^2+8x+16 <br>and the number and type of roots​
vfiekz [6]

Answer:

2 imaginary roots

Step-by-step explanation:

The discriminate is the portion of the quadratic equation under the square root

D = b^2 - 4ac

D = 8^2 - 4(2)(16)

D = 64 - 128

D = -64

Since the discriminate is negative the square root will be imaginary

and there will be 2 of them

Where are white blue and red boat in the Marina three fourths of the boats in the Marina are white for seventh of the remaining
xeze [42]

Answer:

28

Step-by-step explanation:

Here is the complete question used in answering this question :

Three-fourths of the boats in the marina are white. 4/7 of the remaining boats are blue , and the rest are red . If there are 9red boats, how many boats are in the marina?

We first have to determine the fraction of the boats that are red

1 - (\frac{3}{4} + \frac{4}{7})

1 - \frac{21 + 16}{28}

1 - \frac{37}{28}

1 - 1\frac{9}{28}

= 9/28

so, 9/28 of the boats are red

let b represent the total number of boats

9/28 x b = 9

to find b, divide both sides of the equation by 28/9

b = 28
