Which statement best describes why there is no real solution to the quadratic equation y = x^2 - 6x + 13?The value of (-6)2 - 4 • 1 • 13 is a perfect square.
The value of (-6)2 - 4 • 1 • 13 is equal to zero.
The value of (-6)2 - 4 • 1 • 13 is negative.
The value of (-6)2 - 4 • 1 • 13 is positive.

Answers

Answer:

The value of (-6)2 - 4 • 1 • 13 is negative.

Step-by-step explanation:

To solve a quadratic equation we can solve by factoring, graphing or through the quadratic formula. The formula is as follows:

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

When the square root value is less than 0, a real solution cannot be found. This means when $b^(2)-4ac<0$ . For the equation, a=1, b=-6 and c=13.

We substitute and simplify.

$b^(2)-4ac=(-6)^2-4(1)(13)=36-4(13)=36-52=-16$

This gives us an imaginary solution because the value of (-6)2 - 4 • 1 • 13 is negative.

Answer this pls.In a class there are 25 females and 70 males . If females avarage is 50 and boys avarage 70, find the mean of the entire class?

Answers

Answer:

the mean of the entire class is approximately 64.74.

Step-by-step explanation:
To find the mean of the entire class, we'll calculate the overall average by considering the total number of students and their average scores.

Total number of students = 25 (females) + 70 (males) = 95 students

Total score of females = 25 (females) * 50 (average score) = 1250

Total score of males = 70 (males) * 70 (average score) = 4900

Total score of the entire class = 1250 (females' total score) + 4900 (males' total score) = 6150

Mean of the entire class = Total score of the entire class / Total number of students = 6150 / 95 ≈ 64.74

So, the mean of the entire class is approximately 64.74.

Find the perimeter and area of a rectangle of cardboard measuring 9.3 cm by 10.6 cm Perimeter: cm Area: cm2

Answers

Answer:

The area of the rectangle is 98.58 $cm^2$

Perimeter is 39.8 cm.

Step-by-step explanation:

Given:

Width of the rectangle =9.3 cm

Length of the rectangle = 10.6 cm

To find:

Perimeter of the rectangle=?

Area of the rectangle=?

Solution:

We know that,

Area of rectangle = length x breadth

Area of rectangle = 9.3 x 10.6

Area of rectangle = 98.58

Now,

Perimeter of rectangle = 2(length + width)

Perimeter of rectangle = 2(10.6 + 9.3)

Perimeter of rectangle = 2 x 19.9

Perimeter of rectangle = 39.8

Perimeter: 18.6cm

Area: 98.58cm2

Hope it helps!
