The sum of the angles of a regular hexagon is 720 degrees. Solve for x

Answer:

This is a false statement so there is no solution.

Step-by-step explanation:

2-(n+2) > -(7 +n) + 7

2 -n -2 > -7 -n + 7

-n > -n  This cannot be true, so there is not solution.

Answer:

No solutions

Step-by-step explanation:

2-(n+2) > -(7+n)+7  Distribute the -1 to both parentheses

2 - n - 2 > -7 - n + 7   Simplify values (2 - 2; -7 + 7)

-n > -n   Add n to both sides

No solutions (There are no solutions because when the equation simplifies, there are no variables and values left)

The temperature is less that 4.4 °F for altitudes greater than 2.021 miles high.

Herein we find that the temperature, in grades Fahrenheit, decreases linearly inasmuch as the altitude, in miles, increases. In accordance with the statement, we solve for T in the following inequality:

63 - 29 · x < 4.4

63 - 4.4 < 29 · x

58.6 < 29 · x

29 · x > 58.6

Step-by-step explanation:

The Residual is -8.4 hours and the interpretation of the given residual is that the carnation stayed fresh for 8.4 hours less than expected based on how much sugar it received.

A residual plot is a type of scatter plot where the horizontal axis represents the independent variable, or input variable of the data, and the vertical axis represents the residual values.

Now, looking at the given residual plot and using a calculator online, we can say that the equation of the least squares regression line is;

y^ = 180.8 + 15.2x

Now, for 2 tablespoons of sugar , we have x = 2. Thus;

y^ = 180.8 + 15.2(2)

y^ = 212.4 hours

Residual for 204 hours is;

Residual = 204 - 212.4 = -8.4 hours

Thus, the interpretation of the given residual is that the carnation stayed fresh for 8.4 hours less than expected based on how much sugar it received.

Does adding sugar to the water in a vase help flowers stay fresh? To find out, two statistics students went to a flower shop and randomly selected 12 carnations. When they got home, the students prepared 12 identical vases with exactly the same amount of water in each vase. They put one tablespoon of sugarin 3 vases, two tablespoons of sugar in 3 vases, and three tablespoons of sugar in 3 vases.In the remaining 3 vases, they put no sugar. After the vases were prepared, the students randomly assigned 1 carnation to each vase and observed how many hours each flower continued to look fresh.

Calculate and interpret the residual for the flower that had 2 tablespoons of sugar and looked fresh for 204 hours.

f(x) = function

you can see -6, 4 and seven are the values of x, which is not a function. and -2 is value of f(x) which is a function

The degree of the polynomial is a f(x)=x^3-2x^2+16x-32.

According to the statement

We have to find that the degree of the polynomial.

So, For this purpose, we know that the

The degree of a polynomial is the highest power of the variable in a polynomial expression.

From the given information:

with real coefficients having zeros 2 and 4 i and a lead coefficient of 1.

Then

We know that the complex zeros always occur in pairs.

zeros are 2,4i,-4i

f(x)=(x-2)(x-4i)(x+4i)

f(x)=(x-2)((x)^2-(4i)^2)

f(x)=(x-2)(x^2-16i^2)

f(x)=(x-2)(x^2+16)

f(x)=x^3-2x^2+16x-32.

So, The degree of the polynomial is a f(x)=x^3-2x^2+16x-32.

Answer:

Step-by-step explanation:

Molar mass

Na = 22.99

S = 32.07

O = 16

Na(2) + S + O(4) =

22.99(2) + 32.07 + 16(4) =

45.98 + 32.07 + 64 = 142.05g

Na2SO4 = 142.05g

2.6 x 10^-3 moles = 0.0026 moles

0.0026 x 142.05 = 0.36933

Step-by-step explanation:

Mid point of AB is (0, -3)

Coordinate of A is (6, -5)

By using mid point formula, if P(x, y) and Q (x′, y′), then mid point of P= (x + x′)/2 , (y + y′)/2

So, ( 0, -3)= 6+x/2, -5+y/2

0=6+x/2

0=6+x, x = -6

and, -3= -5+y/2, -6= -5+y....

y = -1

so the coordinate is (-6, -1)

To find the midpoint of two points, we can use the following formula:

[tex]midpoint=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]

We're given:

Plug the information into the formula:

[tex]midpoint=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})\\\\(0,-3)=(\dfrac{6+x_2}{2},\dfrac{-5+y_2}{2})[/tex]

If [tex]\dfrac{6+x_2}{2}[/tex] must equal 0, then [tex]x_2[/tex] must be -6.

If [tex]\dfrac{-5+y_2}{2}[/tex] must equal -3, then [tex]-5+y_2[/tex] must equal -6, making [tex]y_2[/tex] equal to -1.

Therefore, BB is (-6,-1).

The equation is 50 = (5 + w)w and the width is 5 and the length is 10

The given parameters are

Area = 50

Length = 5 + Width

This means that

l = 5 + w

The area is calculated as

A = lw

Substitute l = 5 + w in A = lw

A = (5 + w)w

Substitute A = 50 in A = (5 + w)w

50 = (5 + w)w

Hence, the equation is 50 = (5 + w)w

We have

50 = (5 + w)w

Express 50 as 10 * 5

So, we have

10 * 5 = (5 + w)w

This means that

5 + w = 10

w = 5

Solve 5 + w = 10

w = 5

Substitute w = 5 in l = 5 + w

The instantaneous rate of change is the change in the concentration of rate that occurs at a particular point of time. The variation in the derivative values at a particular point  denotes the instantaneous rate of change.  The instantaneous rate of change at a point is the value of  derivative function evaluated at that point.

P(x) = −0.03x^2 + 225x − 24000

To find the instantaneous rate of change we need to differentiate the equation with respect to x

P'(x) = -0.06x +225

at x =0

P'(0)= 225

now put x = 1000 because we need  to know   instantaneous rate of change of the profit at x = 1000 iPhones sold

P'(1000) = -0.06(1000) + 225

               = -60 + 225

               = 165

Hence, the instantaneous rate of change of the profit at x = 1000 iPhones sold is 165

The minimum value of the function is = -12

The function g(x) is defined for integers x such that if x is even, g(x) = x/2 and if x is odd, g(x) = x + 5.

given that , g(x)= x^2 - 6x - 12

asked to find minimum value

to get minimum value of g(x) put x=0

on  putting x=0 ,the value of x^2 becomes 0

                           the value of 6x also becomes 0

so the equation g(0) becomes 0-0-12

            g(0)= -12

Answer:

The function's minimum value is -12.

Step-by-step explanation:

Integers x are used to define the function g(x), and it is defined so that if x is even, g(x) = x/2 and if x is odd, g(x) = x + 5.

Considering, g(x)=x2 - 6x - 12

requested to determine the minimal value

Put x=0 to obtain the minimal value of g(x).

When x=0 is entered, the value of x2 is changed to 0.

6x's value is also reduced to 0.

so the equation g(0) becomes 0-0-12

           g(0)= -12

on putting x=0 we get g(0) as -12 which is its minimum value

we get minimum value for g(x) when x=0

The simplification of the given equation is (x² + 8x - 16)/(x-4)(x+4) by the method of LCM.

For, the given equation;

4/(x+4) + (x/x-4)

To find the common denominator, use LCM; multiply a first term by (x-4)/(x-4) and the 2nd term by (x+4)/(x+4):

= (x-4)×4/(x-4)(x+4) +  x×(x+4)/(x-4)(x+4)

The following step is to disperse the 4 (x-4) and x (x+4);

So you now have;

= (4x-16 + x² + 4x)/(x-4)(x+4)

Further simplify.

= (x² + 8x - 16)/(x-4)(x+4)

As, (x² + 8x - 16) is further not factor-able. So, the simplified form of the given equation is; (x² + 8x - 16)/(x-4)(x+4).
