Answer:

9) Is D. 154

10) B. Supplementary

11) B. Perpendicular

12) A. J and K

Step-by-step explanation:

9) Supplementary angles equal 180 degrees. Complementary angels are 90 degrees. If angle A is 64; subtract 64 from 90. The difference is angle B.

90-64=26

If angle B is 26 degrees, subtract 26 from 180.

180-26=154.

10) Angle 1 and 2 equal 180 degrees, which is a supplementary angle

11) Lines AD and AC meet up to form a right angle. A perpendicular angle.

12) Parallel lines are two lines that never meet up.

Captown is the capital city of maltania. if the population of captown is 25 percent of the rest of the population of maltania, t

Fofino [41]

You can just overall divide 100 from 25 to get a percentage because you're trying to find the percentage of captown only but per se if you were to find various cities in Maltania than you can just divide 100 by the percent of the population.

f(x) = 4x^2+2x+6 What is the value of the discriminant of f? How many distinct real number zeros does f have?

Sauron [17]

Answer:

The value of Discriminant of the function is -92

It has ZERO distinct real number zeros.

Step-by-step explanation:

Given:

$f(x)=4x^{2} +2x+6$

Which is a Quadratic Equation in the general form of

$ax^{2}+bx+c=0$

where a,b and c are constants.So on comparing the given equation with general form we get,

$a=4\\b=2\\c=6$

Formula for discriminant we have

$Discriminant=b^{2}-4ac\\ =2^{2}-4(4)(6)\\ =4-96\\=-92$

now for zeros we have

$x=\frac{-b+\sqrt{b^{2-4ac} } }{2a} \\or\\x=\frac{-b-\sqrt{b^{2-4ac} } }{2a} \\$

on substituting these values we get

$x=\frac{-2+\sqrt{-92} }{8}$

$x=\frac{-2-\sqrt{-92} }{8}$

the term $\sqrt{-92}$ is imaginary

hence the zeros are not real number
