how to solve for -5x^2-2x-6=-2 ?

The graphs of y = |x| and y = |x| - 4 are similar in their overall V-shape and slope behavior, but differ in their vertical position due to the constant term difference in the equations. The second graph is essentially a downward translation of the first by 4 units.

Similarities:

Both represent absolute value functions.

Both graphs pass through the origin (0, 0)

Both graphs have a slope of 1 for positive values of x and a slope of -1 for negative values of x.

Differences:

The graph of y = |x| - 4 is shifted downwards by 4 units

The y-intercept is different for both graphs.

Step-by-step explanation:

Amos Tversky and Daniel Kahneman proposed the prospect theory that aimed to explain and understand the behavior of individuals, giving them a sample of choices to take, when put in front to the different decisions that had to be made, people often valued chances that were 99% probable to happen with a 95 to 85% chance, meaning that the didn´t give enough credit to the number and probabilities, and when facing risks of 1% probability of happening, they outweigh them with a 5 to 15 %.

To solve for the surface area of the pyramid, we make use of the formula:

A= l w + l [sqrt ((w / 2)^2 + h^2)] + w [sqrt ((l / 2)^2 + h^2))

where,

l and w are the base of the pyramid = 100 mm

h is the height of the pyramid = 75 mm

Substituting the given values into the equation:

A= 100 * 100 + 100 [sqrt ((100 / 2)^2 + 75^2)] + 100 [sqrt ((100 / 2)^2 + 75^2))

A = 10,000 + 100 (sqrt 2575) + 100 (sqrt 2575)

A = 20,148.90 mm^2

Therefore the surface area of the pyramid is about 20,149 mm^2.

this would have to be an inequality equation.

The least common multiple of 2/3 5/6 and 9/4 is 12.

A fraction represents a part of a number or any number of equal parts.

A fraction consisting of a quotient and remainder is a mixed fraction. we can convert the mixed fraction to improper fraction by first dividing the numerator by denominator and then taking the quotient as whole number and remainder as the numerator of proper fraction keeping the denominator same.

We are given that;

The numbers 2/3 5/6 and 9/4

Now,

To find the least common multiple of fractions, we need to find the least common multiple of their denominators and divide it by the greatest common factor of their numerators. The steps are:

Multiples of 3: 3, 6, 9, 12, 15, 18,

Multiples of 6: 6, 12, 18,

Multiples of 4: 4, 8, 12,

Find the greatest common factor of 2, 5 and 9. This is the largest number that can divide all three numbers without leaving a remainder. One way to do this is to list the factors of each number and find the largest one that they have in common. For example:

Factors of 2: 1 and 2

Factors of 5: 1 and 5

Factors of 9: 1,3 and9

The only common factor is 1, so this is the greatest common factor of the numerators.

Divide the least common multiple of the denominators by the greatest common factor of the numerators. This gives us:

To find the angle formed by a diagonal of a rectangular box with its base, calculate the base diagonal using the Pythagorean Theorem and then use the inverse tangent function with the height and base diagonal as arguments.

The angle formed by a diagonal of the rectangular box with the base of the box can be found using the Pythagorean Theorem. In this case, the box has a length of 6, a width of 4, and a height of 5. The diagonal of the base can be calculated as the hypotenuse of a right triangle formed by the length and the width. According to the Pythagorean theorem, this diagonal (D) is √(6² + 4²) which is √(36 + 16) or √52. To find the angle between the box's base diagonal and the body diagonal (which includes the height), we need to use trigonometry, specifically the inverse tangent function (tan-1). So we have the length of the box's base diagonal (D) and the height (H), forming a right triangle with the body diagonal as the hypotenuse. The angle θ can be calculated using tan-1(H/D), where H is the height of the box and D is the length of the diagonal on the base. This equates to tan-1(5/√52). Evaluating this expression with a calculator gives us the angle θ formed by the body diagonal with the base of the box.

the discriminant of the equation [tex]\(3x^2 - 10x + 2 = 0\)[/tex] is [tex]\(76\)[/tex].

To find the discriminant of the quadratic equation [tex]\(3x^2 - 10x + 2 = 0\)[/tex], we first need to rewrite it in the standard form [tex]\(ax^2 + bx + c = 0\)[/tex].

The given equation is [tex]\(3x^2 - 10x + 2 = 0\)[/tex].

Comparing it with the standard form [tex]\(ax^2 + bx + c = 0\)[/tex], we have:

- [tex]\(a = 3\)[/tex],

- [tex]\(b = -10\)[/tex],

- [tex]\(c = 2\).[/tex]

The discriminant [tex](\(D\))[/tex] of a quadratic equation [tex]\(ax^2 + bx + c = 0\)[/tex] is given by the formula:

[tex]\[ D = b^2 - 4ac \][/tex]

Substituting the values of [tex]\(a\), \(b\)[/tex], and [tex]\(c\)[/tex], we get:

[tex]\[ D = (-10)^2 - 4 \cdot 3 \cdot 2 \][/tex]

[tex]\[ D = 100 - 24 \][/tex]

[tex]\[ D = 76 \][/tex]

So, the discriminant of the equation [tex]\(3x^2 - 10x + 2 = 0\)[/tex] is [tex]\(76\)[/tex].

Answer: The answer is (B) [tex]47\dfrac{7}{12}[/tex].

Step-by-step explanation:  We are given to find the difference between the following two numbers:

[tex]n_1=126\dfrac{1}{4},~~~n_2=78\dfrac{2}{3}.[/tex]

To find the difference, we need to subtract the smaller number from the larger one.

Since, [tex]n_1>n_2[/tex], so the difference is given by

[tex]d\\\\=n_1-n_2\\\\=126\dfrac{1}{4}-78\dfrac{2}{3}\\\\=\dfrac{505}{4}-\dfrac{236}{3}\\\\=\dfrac{505\times3-236\times4}{12}\\\\=\dfrac{1515-944}{12}\\\\=\dfrac{571}{12}\\\\=47\dfrac{7}{12}.[/tex]

Thus, (B) [tex]47\dfrac{7}{12}[/tex] is the correct option.

To make line segment AB parallel to line segment CD, we calculate the slope of CD and ensure AB has the same slope. The slope of CD is −1/4.5, and setting the slope of AB equal to this value leads to the conclusion that y = −2 for point A.

To determine the value of y such that the line segment with endpoints A(−3, y) and B(6, −4) is parallel to the line segment with endpoints C(7, 6) and D(−2, 8), we need to ensure that the slope of line AB is equal to the slope of line CD. The slope m of a line passing through two points (x1, y1) and (x2, y2) is given by m = (y2 − y1) / (x2 − x1).

For line CD, the slope is (8 − 6) / (−2 − 7) = 2 / (−9) = −1/4.5. To find the value of y for point A so that line AB is parallel to CD, we need to set the slope of AB equal to −1/4.5:

(−4 − y) / (6 − (−3)) = −1/4.5
(−4 − y) / 9 = −1/4.5
−4 − y = −9 / 4.5
y = −4 + 2 = −2

Therefore, the correct value of y that makes line AB parallel to line CD is −2.

The x-coordinate of the vertex is 2 and the y-coordinate is -10. The discriminant is 144.

The quadratic function can be rearranged into the form ax² + bx + c = 0, where a = 2, b = -8, and c = -10. To find the x-coordinate of the vertex, we use the formula x = -b / (2a). Plugging in the values, we get x = -(-8) / (2*2) = 2. The y-coordinate of the vertex can be found by substituting the x-coordinate into the original function. Plugging in x = 2, we get f(2) = 2(2)² - 8(2) - 10 = -10.

The discriminant is calculated as b² - 4ac. Plugging in the values, we get (-8)² - 4(2)(-10) = 64 + 80 = 144.
