Evaluate the following expression when x = 3 and y = 4:

Fraction with x squared plus y cubed in the numerator and 2 plus x in the denominator.

3.6
8.6
14.6
21.6

Answer:

the function is y= 100-0.095x

Step-by-step explanation:

Step one:

given data

A stock valued at $100 decreases in value by 9.5%

let the number of years be x

Step two:

Hence, the rate of decrease is 0.095

therefore the function is

y= 100-0.095x

The function which represents the situation is

[tex]f(x) = 100 - {0.95}^{x} [/tex]

Percentage decrease per year = 9.5%

= 9.5/100

= 0.095

f(x) = 100 - 0.095^x

[tex]f(x) = 100 - {0.95}^{x} [/tex]

Therefore, the function which represents the situation is f(x) = 100 - 0.095^x

A system of writing numbers is known as a number system. It is the mathematical notation for consistently employing digits or other symbols to represent the numbers in a particular set. It represents the arithmetic and algebraic structure of the numbers and gives each number a distinct representation.

Given:

a) 18 is 3 more than 9.

But, 3 more than 9.= 12

So, it is false

b) 18 is 3 times as much as 6.

= 3 x 6

= 18

So, it is true

c) 19 is 3 times as much as 27.

= 3 x 27

= 81

So, it is false

d) 9 is 3 more than 6

= 3+6

= 9

So, it is true

The answer is quadratic

Step-by-step explanation:

It is quadratic because the correct answer is quadratic

The graph is showing the quadratic function.

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree. A quadratic function must have at least one second-degree term. It performs algebraic operations.

As, the linear function have graph consist of straight line.

Then, The quadratic function has the shape of a parabola and has the variable squared.  

and, exponential function have raising curve or falling curve.

As, per the given graph the curve shows parabola which is quadratic in nature.

Answer:

x = 3 + 7i   or   x = 3 - 7i; a = 3; b = 7

Step-by-step explanation:

x^2 - 6x = -58

We complete the square by adding the square of half of the coefficient of the x-term to both sides.

x^2 - 6x + 9 = -58 + 9

(x - 3)^2 = -49

[tex] x - 3 = \pm 7i [/tex]

x = 3 + 7i   or   x = 3 - 7i

a = 3; b = 7

The required value of a and b for the solution of the given equation is 3 and 7 respectively.

Given that,
To determine the solutions of this quadratic equation x² - 6x= -58 and Substitute the values of a and b to complete the solution.
x= a+bi
x=a -bi​

The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.

Here,
Given equation,
x² - 6x= -58

Completing the square of the above equation by adding and subtracting the square of the half of the coefficient of x.
x² - 6x + 9 - 9 = -58
(x - 3)² = -58 + 9
(x - 3)² = -49
x - 3 = √-49
x - 3 = ±7i
x = 3 ±7i
Now,
The required
a + bi = 3 + 7i
a - bi = 3 - 7i

Thus the required value of a and b for the solution of the given equation is 3 and 7 respectively.
