The answer is 1/2.

Answer:

Step-by-step explanation:

A+B= we will add both expressions

A+B=3x^4+2x^2-2x+1-2x^3+4x^2-3  we will add like terms

A+B= 3x^4-2x^3+6x^2-2x-2

A-B=3x^4+2x^2-2x+1-(-2x^3+4x^2-3)

A-B=3x^4+2x^2-2x+1+2x^3-4x^2+3

A-B=3x^4+2x^3-2x^2-2x+4

Answer:

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: Plus or minus 1 standard deviation from the mean.

Step-by-step explanation:

According to the Empirical rule,

If the population is normally distributed then, about 68% of the population lies within 1 standard deviation from the mean value.

Here, the data shows 68% percent of the area under the normal  distribution.

This is equivalent to "plus or minus 1 standard deviation from the mean."

Hence, the correct option is : plus or minus 1 standard deviation from the mean.

May have rained 2.5 more inches then in April. First you would need to subtract 9.4 because that’s how much it rained in May and then subtract it with 6.9 because that’s how much it rained in April.

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.

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

Answer:

Step-by-step explanation:

Substitute 3x into y=-4x-49

y=−4x−49

3x=−4x−49

3x+4x=−4x−49+4x(Add 4x to both sides)

7x/7=−49/7

(Divide both sides by 7)

x=−7

Step: Substitute−7forxiny=3x:

y=3x

y=(3)(−7)

y=−21(Simplify both sides of the equation)

Answer:

x=−7 and y=−21

The solution set to the given system of equation is (- 7, - 21).

Given are the system of equations as follows -

y = 3x

y = - 4x - 49

We have the equations as -

y = 3x             .... Eq [1]

y = - 4x - 49     .... Eq [2]

Now, we can write the equation [2] as -

3x = - 4x - 49

7x = -49

x = - 7

So, we can find the value of [y] as -

y = 3x

y = 3 x - 7

y = - 21

Therefore, the solution set to the given system of equation is (- 7, - 21).

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
