What is the slope of the line that passes through the points (-9, 7) and (8, -6)?

Answers

Answer: -13/17

Step-by-step explanation: To find the slope of the line that passes through the points (-9, 7) and (8, -6), you can use the slope formula:

slope = (y2 - y1) / (x2 - x1)

where (x1, y1) = (-9, 7) and (x2, y2) = (8, -6)

Substituting the values in the formula, we get:

What are the roots of the quadratic equation x² + 4x + 7 = 0?

A) 2 + i√3 or 2 - i√3



B) x = -2 + i√3 or -2 - i√3


C) x = -7 or 1


D) non of above

Answers

Answer:

The roots of the quadratic equation x² + 4x + 7 = 0 can be found using the quadratic formula: x = (-b ± √(b² - 4ac)) / 2a

In this case, a = 1, b = 4, and c = 7. Substituting these values into the formula, we get:

x = (-4 ± √(4² - 4(1)(7))) / 2(1)

x = (-4 ± √(16 - 28)) / 2

x = (-4 ± √(-12)) / 2

x = (-4 ± 2i√3) / 2

x = -2 ± i√3

Therefore, the roots of the equation x² + 4x + 7 = 0 are: A) 2 + i√3 or 2 - i√3.

So, the correct answer is A

write a quadratic function in standard form that passes through (-4,0) , (5,0) , and (3,14) .

Answers

To write a quadratic function in standard form that passes through (-4,0), (5,0), and (3,14), we can use the fact that a quadratic function has the form:

y = ax^2 + bx + c

where a, b, and c are constants. To find the values of these constants, we can substitute the coordinates of the three given points into the quadratic function and solve for a, b, and c. This gives us three equations:

0 = 16a - 4b + c
0 = 25a + 5b + c
14 = 9a + 3b + c

We can solve these equations using algebraic methods, such as elimination or substitution. One possible method is to subtract the first equation from the second equation and solve for b:

0 = 9a + 9b
b = -a

Substituting this into the third equation and simplifying, we get:

14 = 9a - 3a + c
14 = 6a + c
c = 14 - 6a

Substituting these values of b and c into the first equation and simplifying, we get:

0 = 16a + 4a(5) + (14 - 6a)
0 = 10a + 14
a = -7/5

Substituting this value of a into the expressions for b and c, we get:

b = 7/5
c = 98/5

Therefore, the quadratic function in standard form that passes through (-4,0), (5,0), and (3,14) is:

y = (-7/5)x^2 + (7/5)x + 98/5

or

y = -1.4x^2 + 1.4x + 19.6

Construct a polynomial function with the following properties: fifth degree, 3 is a zero of multiplicity 3,-4 is the only other zero, leading coefficient is 4.

Answers

The polynomial function with fifth degree and given zeroes is 4x⁵ - 20x⁴ + 64x³ + 324x² - 432x.

What is degree of a polynomial?

The maximum power of the variable in a polynomial function is its degree. For instance, since 2 is the largest power of x, the polynomial function f(x) = 3x2 + 2x + 1 has a degree of 2. We only take into account the degree of the term with the highest power of x when a polynomial function comprises many terms. A polynomial with no x terms is a constant function, and thus has degree zero.

To determine the polynomial, we determine the zeroes.

Given that, 3 is a zero of multiplicity 3,-4 is the only other zero thus:

(x - 3)³(x + 4)

Now, for leading coefficient 4 we have:

4x(x - 3)³(x + 4)

Thus, solving the parentheses we have:

4x(x³ - 9x² + 27x - 27)(x + 4)

(4x⁴ - 36x³ + 108x² - 108x)(x + 4)

4x⁵ - 36x⁴ + 108x³ - 108x² + 16x⁴ - 144x³ + 432x² - 432x

4x⁵ - 20x⁴ + 64x³ + 324x² - 432x

Answers

The annual depreciation expense for this car is $1,833.33.

What is the depreciation formula?

Simply deduct the vehicle's current fair market value from the purchase price, less any applicable sales tax or fees, to determine how much value has been lost.

We must determine the total depreciation throughout the vehicle's useful life and divide it by the number of years to determine the annual depreciation expense:

Total depreciation = purchase price - resale value

= $28,500 - $17,500

= $11,000

Annual depreciation expense = total depreciation / useful life = $11,000 / 6 = $1,833.33 (rounded to the nearest hundredth)

The width of a block of wood with rectangular cross-section is x cm . it's height is two - thirds its width and it's length is 4 times its height. What is its volume in cm3​

Answers

The volume (V) of a rectangular block of wood can be found by multiplying its length, width, and height:

V = lwh

From the problem, we know that the height (h) is two-thirds of the width (x), or h = (2/3)x. We also know that the length (l) is 4 times the height, or l = 4h. Substituting these values into the formula for volume, we get:

V = lwh = (4h)(x)(h) = 4xh^2

Substituting h = (2/3)x, we get:

V = 4x((2/3)x)^2 = 4x(4/9)x^2 = (16/9)x^3

Therefore, the volume of the block of wood is (16/9)x^3 cubic centimeters.

From the calculations, only question 2 shows that f(x) is the inverse of function g(x) as the rest shows the parent functions are not inverse of g(x)

What are the inverse of the function

In the given question, we are to determine if the parent function f(x) is an inverse to g(x).

1. f(x) = 2x - 9

To find the inverse function, swap x and y, and solve the resulting equation for x.

If the initial function is not one-to-one, then there will be more than one inverse.

Let's switch the variables: y = 2x - 9 to x= 2y - 9.

We can proceed to solve the equation as;

x =2y - 9 for y.

y= x + 9 / 2

Therefore, f(x) is not an inverse of g(x)

2. f(x) = x - 3 / 4

To find the inverse function, swap x and y, and solve the resulting equation for x.

If the initial function is not one-to-one, then there will be more than one inverse.

Let's switch the variables:

y = x / 4 - 3/4 to x = y / 4 - 3/4

we can solve the equation for y to give us;

y = 4x + 3

This shows that f(x) is inverse of g(x)

4. f(x) = 7x^3/2 - 4

To find the inverse function, swap x and y and solve the resulting equation for x

If the initial function is not one-to-one, then there will be more than one inverse.

So, swap the variables:

y = 7x^3/2 - 4 will become x = 7y^3/2 - 4

Solving for y;

y = [(∛7(x + 4))^2/3] / 7

This shows f(x) is not the inverse of g(x)

a frame of width faround an 8-inch by 10-inch picture.
Find an expression for the perimeter of the entire frame.

Answers

Answer:

The perimeter of the entire frame is equal to the sum of the perimeters of the mat and the picture. The expression for the perimeter of the mat is (2m + 10) + (2m + 8) = 4m + 18, and the expression for the perimeter of the picture is 2(8) + 2(10) = 36. Therefore, the expression for the perimeter of the entire frame is (4m + 18) + 36 = 4m + 54.

A chess board is made using the ratio of square length to king's height, 3.5 inches to 4.5 inches. If a chess board is made with a king's height of 2.25 inches, what is the length of the square?

Answers

The length of the square is 1.75 inches, while the king's height is 2.25 inches.

Define length.

The length of an object or the extent of a one-dimensional object along its longest dimension is measured physically. It is a basic idea in physics and geometry and is frequently expressed in terms of meters (m), centimetres (cm), feet (ft), or inches (in).

According to the information provided, the square length to king's height ratio is 3.5 to 4.5 inches. Let's use this ratio to determine the square's length when the king is 2.25 inches tall.

We may make a proportion to get the square's length:

(square length) / (king's height) = 3.5/4.5

king's height = 2.25

Let's substitute the given values:

(square length) / 2.25 = 3.5/4.5

To solve for the length of the square, we can cross-multiply:

(square length) = (2.25) x (3.5/4.5)

(square length) = 1.75

Therefore, the length of the square is 1.75 inches, while the king's height is 2.25 inches.
