What is the sum of the measures, in degrees, of the interior angles of a 16- sided polygon?

Answer:

Option D is correct.

Step-by-step explanation:

We need to find that how many quarts are there in 583.7 liters.

From conversion table we geet,

1 quart = 0.95 liters

=> 1 liters = 1/0.95 quarts

=> 1 liters = 1.0526 quarts

I liter has 1.0526 quarts then 583.7 liters will have:

583.7 liters = 1.0526*583.7 quarts

583.7 liters = 614,4 quarts.

So, Option D There are 614.4 quarts in 583.7 liters. is correct.

Answer:

b) [tex]12x^2-48x+21[/tex] ; all real numbers

Step-by-step explanation:

f and g are polynomials and polynomials have domain all real numbers.

This is because when you input any number there will always be a existing output. There are no restrictions on what you can plug into a polynomial.

So the answer is either b or c.

[tex](f \times g)(x)=f(x) \times g(x)[/tex]

[tex](f \times g)(x)=(-2x+7) \times (-6x+3)[/tex]

[tex]f \times g)(x)=(-2x+7)(-6x+3)[/tex]

Let's use foil!

First: [tex]-2x(-6x)=12x^2[/tex]

Outer: [tex]-2x(3)=-6x[/tex]

Inner:  [tex]7(-6x)=-42x[/tex]

Last:  [tex]7(3)=21[/tex]

-----------------------------Add like terms:

[tex]12x^2-48x+21[/tex]

The answer is b.

Answer:

y=-5x-58

Step-by-step explanation:

The equation of a line in slope-intercept form is y=mx+b where m is the slope and b is the y-intercept.

Perpendicular lines have opposite reciprocal slopes.

Anyways we need to find the slope of the line going through (10,6) and (5,5).

To find the slope, we are going to line up the points vertically and subtract vertically, then put 2nd difference over 1st difference. Like so:

 (  10   ,   6)

- (   5   ,   5)

------------------

    5         1

So the slope of the line through (10,6) and (5,5) is 1/5.

The slope of a line that is perpendicular will be the opposite reciprocal of 1/5.

The opposite reciprocal of 1/5 is -5.

The line we are looking for is y=-5x+b where we need to find the y-intercept b.

y=-5x+b goes through (-10,-8)

So we can use (x,y)=(-10,-8) to find b in y=-5x+b.

y=-5x+b with (x,y)=(-10,-8)

-8=-5(-10)+b

-8=50+b

Subtract 50 on both sides:

-8-50=b

-58=b

So the equation is y=-5x-58

79.67479675 %

Step-by-step explanation:

To find the percentage take the correct amount over the total amount, then multiply by 100

98/123 * 100

79.67479675 %

Answer:

the answer is 79.64%

Step-by-step explanation:

A/B=P/100

98/123=p/100

9800/123=123p/123

p=79.64%

We found the values of the function f(x) at points 1 and 3 and compared them. It's found that the value of f(1) is significantly larger than the value of f(3), hence the third statement is true.

To answer your question, we need to substitute 1 and 3 into the function f(x)=-2x^2+3x+10, respectively. So:

For f(1), we get -2*1^2 + 3*1 + 10 = -2 + 3 + 10 = 11.

For f(3), we get -2*3^2 + 3*3 + 10 = -18 + 9 + 10 = 1.

Therefore, we can clearly see that the value of f(1) is larger than the value of f(3), meaning the third statement is true.

Answer:

[tex]y'=\frac{y^2-xy\ln(y)}{x^2-xy\ln(x)}[/tex]

Step-by-step explanation:

Take natural log of both sides first.

[tex]x^y=y^x[/tex]

[tex]\ln(x^y)=\ln(y^x)[/tex]

Taking the natural log of both sides allows you to bring down the powers.

[tex]y\ln(x)=x\ln(y)[/tex]

I'm going to differentiate both sides using the power rule.

[tex](y)'(\ln(x))+(\ln(x))'y=(x)'(\ln(y))+(\ln(y))'x[/tex]

Now recall (ln(x))'=(x)'/x=1/x while (ln(y))'=(y)'/y=y'/y.

[tex]y'(\ln(x))+\frac{1}{x}y=1(\ln(y))+\frac{y'}{y}x[/tex]

Simplifying a bit:

[tex]y' \ln(x)+\frac{y}{x}=\ln(y)+\frac{y'}{y}x[/tex]

Now going to gather my terms with y' on one side while gathering other terms without y' on the opposing side.

Subtracting y'ln(x) and ln(y) on both sides gives:

[tex]\frac{y}{x}-\ln(y)=-y'\ln(x)+\frac{y'}{y}x[/tex]

Now I'm going to factor out the y' on the right hand side:

[tex]\frac{y}{x}-\ln(y)=(-\ln(x)+\frac{x}{y})y'[/tex]

Now we get to get y' by itself by dividing both sides by (-ln(x)+x/y):

[tex]\frac{\frac{y}{x}-\ln(y)}{-\ln(x)+\frac{x}{y}}=y'[/tex]

Now this looks nasty to write mini-fractions inside a bigger fraction.

So we are going to multiply top and bottom by xy giving us:

[tex]\frac{y^2-yx\ln(y)}{-xy\ln(x)+x^2}=y'[/tex]

[tex]y'=\frac{y^2-xy\ln(y)}{x^2-xy\ln(x)}[/tex]

The derivative of the implicit function [tex]x^y = y^x[/tex] is [tex]\[\frac{dy}{dx} = \frac{\ln(y) - \frac{y}{x}}{\ln(x) - \frac{x}{y}}\][/tex].

To find the derivative of the implicit function defined by [tex]\( x^y = y^x \),[/tex] follow these steps:

        [tex]\ln(x^y) = \ln(y^x)[/tex]

        y ln(x) = x ln(y)

Differentiate both sides with respect to x. Use implicit differentiation where y is considered a function of x:

        [tex]\[ \frac{d}{dx}[y \ln(x)] = \frac{dy}{dx} \ln(x) + y \cdot \frac{1}{x} \][/tex]

        [tex]\[ \frac{d}{dx}[x \ln(y)] = \ln(y) + x \cdot \frac{1}{y} \cdot \frac{dy}{dx} \][/tex]

        [tex]\[ \frac{dy}{dx} \ln(x) + \frac{y}{x} = \ln(y) + \frac{x}{y} \cdot \frac{dy}{dx} \][/tex]

Solve for [tex]\( \frac{dy}{dx} \):[/tex]

        [tex]\[ \frac{dy}{dx} \ln(x) - \frac{x}{y} \cdot \frac{dy}{dx} = \ln(y) - \frac{y}{x} \][/tex]

        [tex]\[ \frac{dy}{dx} \left(\ln(x) - \frac{x}{y}\right) = \ln(y) - \frac{y}{x} \][/tex]

        [tex]\[ \frac{dy}{dx} = \frac{\ln(y) - \frac{y}{x}}{\ln(x) - \frac{x}{y}} \][/tex]

Answer:

The answer is C

Step-by-step explanation:

Use the method of elimination

First rearrange the first equation to look like the second

C) not isomeric because side lengths not same

Step-by-step explanation:

Isometric means that the lengths are preserved after rotation or transformation.

As we can see in the given figures that the lengths of sides of the original figure and transformed figure are are not same which means the lengths are not preserved.

So the correct answer is:

C) not isomeric because side lengths not same ..

Option: C is the correct answer.

C)   Not isomeric because side lengths not same.

Isometry--

It is a transformation which preserves the length of  the original figure i.e. it is a distance preserving transformation.

Two figures are said to be isometric if they are congruent.

By looking at the figure displaying the transformation we observe that the size of the original figure is changed.

i.e. the figure is dilated by a scale factor of 2 , since each of the sides of the polygon which is a trapezoid is increased by a factor of 2.

Hence, the transformation is not an isometry.

The system of equation will have one solution.

The correct answer is an option (B)

It is a collection of one or more linear equation involving the same variable.

For given question,

Two equations have negative reciprocal slope .

Which means if one equation have slope = m

then slope of other equation will be = -1/m

This means, both the lines are perpendicular to each other , hence both the lines must be intersecting each other at one point.

In system of equation , the solution of the two equation is the point where they intersect .

Since, both the lines are intersecting at one point . Hence, it will have only one solution.

Therefore, the correct answer is an option b) the system will have one solution

Answer:

the two expressions are equivalent.

Step-by-step explanation:

We know that f(x)= 3x-7 and g(x)= -2x+5, therefore:

f(x) - (-g(x)) = 3x-7 - ( +2x-5) = 3x - 7 - 2x + 5 = x -2

f(x) + g(x) = 3x-7 -2x + 5 = x - 2

Therefore,  f(x) - (-g(x)) is equivalent to f(x) + g(x).

Another way to check that the two expressions are equivalent is by solving the parenthesis:

f(x) - (-g(x)) →  f(x) + g(x)

Therefore, the two expressions are equivalent.

Answer:

Josh has 29 coins.

Step-by-step explanation:

Let Terry have x coins then Josh has x + 12 coins.

Together they have x + x + 12 coins so we can form the equation:

x + x + 12 = 46

2x + 12 = 46

2x = 46 - 12 = 34

x = 17, so Terry has 17 coins and Josh has 17 + 12 = 29 coins.

Answer:

Piston displacement = 84.8

Step-by-step explanation:

We will find the volume of the cylinder in order to find the piston displacement.

Here, (bore = diameter, so r = diameter/2) (height = stroke)

Volume = [tex] \pi r^2h[/tex] [tex]=3.14\times1.5^2\times 3[/tex] = 21.2 cubic units

Since the engine has 4 cylinders, so we will multiply the piston displacement by 4 to get:

Piston displacement = [tex]21.2 \times 4[/tex] = 84.8

The total piston displacement for a 4-cylinder engine with a bore and stroke of 3 inches can be calculated using the formula: pi/4 * bore^2 * stroke * number of cylinders. For this example, it is approximately 113.097 cubic inches.

To calculate the total piston displacement, we use the formula for the displacement of a single cylinder, which is pi/4 * bore^2 * stroke * number of cylinders.

In this scenario, the bore and stroke are both 3 inches and it's a 4-cylinder engine. Therefore, we plug in these values into the formula.

So, the total displacement is pi/4 * (3inch)^2 * 3inch * 4. This calculates to approximately 113.097 cubic inches.

Step-by-step explanation:

This is a quadratic equation

You can use the graph tool to visualize the x-intercepts on the graph as attached below.

x=-1 or x=3

For this case we must find the x-intersepts values of the following equation:

 [tex]y = -4x ^ 2 + 8x + 12[/tex]

Doing y = 0 we have:

[tex]0 = -4x ^ 2 + 8x + 12[/tex]

Dividing between -4 on both sides of the equation:

[tex]x ^ 2-2x-3 = 0[/tex]

We factor, we look for two numbers that when multiplied by -3 and when added by -2. These are -3 and 1:

[tex]-3 + 1 = -2\\-3 * 1 = -3\\(x-3) (x + 1) = 0[/tex]

Thus, the x-intercepts values are:

f(1) = 3(1)^2-1+4 = 3-1+4 = 2+4 =6

f(2) = 3(2)^2-2+4 = 3(4)-2+4 = 12-2+4 = 10+4 = 14

f(3) = 3(3)^2-3+4 = 3(9)-3+4 = 27-3+4 = 24+4 = 28

Answer: I believe the answer is B.

Although, if the answer to this question isn't B, it should defiantly be C.

Answer:

The correct option is B.

Step-by-step explanation:

The graph of f(x) is g(x) is given.

Graph of both functions intersect each other at a point. Before the point of intersection g(x)>f(x) and after the point of intersection g(x)<f(x).

The graph of f(x) will eventually exceed the graph of g(x). Therefore the correct option is B.

Function g(x)<f(x) for the large value of x, So option A is incorrect.

From the given graph it is clear that the y-intercept of f(x) is 0.2 and y-intercept of g(x) is 2.

So, option C and D are incorrect.
