How can you tell when a quadratic equation has no real solutions? . . A. when the radicand is negative. B. when b in the quadratic formula is greater than the radicand. C. when the radicand equals zero. D. when the radicand is not a perfect square

Answers

Answer 1

Answer: The nature of the roots of a quadratic equation may be readily determined through the use of its discriminant,
D = sqrt (b² - 4ac)
We can tell if the quadratic equation does not have a real root it the radicand is negative. Therefore, the answer is letter A.

Answer 2

Answer:

The answer is option A.

Final answer:

The total number of people at the club meeting is 2c -10 (option B). Further, the correct answer for comparison is that 'A and B are equal' (option C).

Explanation:

In this question, we are told that the number of club members is c and there are 10 more club members than nonmembers. This means that there are c - 10 non-members. Therefore, the total number of people at the club meeting is the sum of the number of members and non-members which is c + (c - 10) = 2c -10. Therefore, the correct answer to the question, 'what is the total number of people at the club meeting?' is: B; 2c-10.

When it comes to choosing between options A, B, C, and D to determine if A (the answer to part A) is higher, B (the answer to part B) is higher, both are equal or there is no answer, we see that since A is actually equal to B, the correct answer is: C, A and B are equal.

The coordinates of the vertices of ANGLE PQR are P(-3,3), Q(2,3), and R(-3,-4). Find the side lengths to the nearest hundredth and the angle measures to the nearest degree.

Answers

Answer: PQ=5, QR=radical 61= 7.81, angle: 50degrees,Why:PQ=|-3|+2=5PR=6angle Alfa, so there is right angle triangle PQR so I can use following formula:PQ^2 + RP^2=QR^2;25 + 36=QR^2;QR=radical 61also I can use: sinus (angle)=PR/QR;sin(angle)=6/radical61=0.76822 which gives angle to be little bit more than 50 degrees{sinus 50 degrees=0,7660}.

the ratio of red marbles to blue marbles in a bag is 4:7. There are 16 red marbles.How many blue marbles are there? solve for indicated variable.

Answers

red marbles : blue marbles = 4:7

16 - red marbles
x - blue marbles

$(16)/(x)=(4)/(7) \n 16 * 7 = 4x \n4 * 7 = x \nx=28$

There are 28 blue marbles.

4x - number of red marbles
7x - number of blue marbles

$4x=16\nx=4\n\n7x=7\cdot4=\boxed{28} \leftarrow \hbox{number of blue marbles}$

Triangle ABC was reflected along the y axis, to produce triangle A'B'C'

Transformation

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.

If a point A(x, y) is reflected along the y axis, the new point is A'(-x, y).

The vertex of triangle ABC is at A(-1, -1). B(-2, -1) and C(-2, -4). If triangle ABC is reflected along the y axis, the new point is at A'(1, -1). B'(2, -1) and C'(2, -4)
