Solve the equation 17.25x + 3.89 = 21.14. Give your answer correct to the nearest integer.

The polynomial without fractions is 2x^4 + x^3 + 7x^2 + 4x - 4.

To make the polynomial contain only whole numbers, we need to find the least common denominator (LCD) of the fractions and multiply each term by the LCD.

The LCD of the fractions 1/2 and 7/2 is 2.

So, we multiply each term by 2 to get rid of the fractions:

2(x^4) + 2(1/2 x^3) + 2(7/2 x^2) + 2(2x) + 2(-2)

Simplifying the terms gives us:

2x^4 + x^3 + 7x^2 + 4x - 4

Therefore, the polynomial without fractions is 2x^4 + x^3 + 7x^2 + 4x - 4.

The slope is -2 while the y-intercept is -1.

[tex] \mathbb{EXPLANATION:}[/tex]

The slope and the intersection with the y-axis of the graph or the y-intercept is already given if you will just simply look at the equation. An equation written in y = mx + b is in slope-intercept form, where m is the slope and b is the y-intercept. So, the number being multiplied to x or the coefficient of x is the slope while the constant is the y-intercept.

The measure of angle 1 would be equal to 59 degrees.

That quadrilateral in which opposite sides are parallel is called a parallelogram.

Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.

We have been given the angles as 31 degrees and 90 degree

We know that the sum of angle of triangle is 180 then the angle 1 will be;

31 + 90 + m∠1 = 180

m∠1 = 180 - 90 - 31

m∠1 = 59

As a result, Jamie could rewrite the equation as (1+sin theta)/cos² theta by multiplying both the denominator and the numerator by (1+sin theta), and then replacing 1-sin² theta with cos² theta.

A ²is part of a whole. The number is expressed mathematically as a quotient, which divides the denominator and the numerator. Both are integers in a simple fraction. A complicated fraction contains a fraction in the numerator or denominator. The denominator of a correct fraction is greater than the numerator

Jamie can double the numerator and write 1/(1-sin theta) to ensure that the fraction's denominator is cos² theta. Neither 1-cos theta nor any other option, but the numerator by (1+sin theta):

1/(1-sin theta) × (1+sin theta)/(1+sin theta) = (1+sin theta)/(1-sin² theta)

We may replace cos² theta for 1-sin² theta using the identity sin² theta + cos² theta = 1:

d^2

When dividing subtract indices OR

dxdxdxdxd /dxdxd

d's cancel out leaving dxd=d^s

The solution to the all given equations is that they have infinite many real solutions

Equation (a)

From the question, we have the following parameters that can be used in our computation:

√(x^2-14x+49)=x-7

When both sides of the equations are squared, we have:

x^2 - 14x + 49 = x^2 - 14x + 49

Evaluate the like terms

0 = 0

This represents infinite many solutions

Equation (b)

Here, we have:

√(4x^2-20x+25)=5-2x

When both sides of the equations are squared, we have:

4x^2-20x+25 = 25 - 20x + 4x^2

Evaluate the like terms

0 = 0

This represents infinite many solutions

For the remaining expressions, we have the following (using the above steps)

Equation (c)

√(y^4+2y^2+1) = y^2 + 1

y^4 + 2y^2 + 1 = y^4 + 2y^2 + 1

0 = 0

Equation (d)

So the slope-intercept form of the equation of the line passing through the two given points is:

y = -5x + 26

If an equation is expressed in the form y=mx+b, where m denotes the slope and b the y-intercept, it is said to be linear.

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

To find the slope of the line passing through the two given points (5,1) and (2,16), we can use the formula:

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

where (x1, y1) = (5,1) and (x2, y2) = (2,16)

m = (16 - 1)/(2 - 5) = -5

So the slope of the line is -5.

To find the y-intercept b, we can use the point-slope form of the equation of a line:

y - y1 = m(x - x1)

Using the point (5,1) and the slope m = -5, we get:

y - 1 = -5(x - 5)

Simplifying this equation, we get:

y = -5x + 26

The value of y is -3. The equation formed from the question is 4x + y = 65 and 5x -3y = 94.

First, we will solve for x

Multiplying the 4x + y = 65 equation by 3 we get

12x +3y =195

Now solving both the equation

The variable y gets cancelled because of having the same value

∴ 17x = 289

x= 17

Now putting the value of x in equation 4x + y = 65 to get the value of y

4*17 +y =65

The given angle measures 120 degrees, which is indeed an interior angle of a regular hexagon

What is hexagon ?

A hexagon is a six-sided polygon, which is a two-dimensional geometric shape with straight sides. The word hexagon comes from the Greek words "hexa" meaning "six" and "gonia" meaning "angle."

To find the value of x in the regular hexagon, we can start by noting that the interior angles of a regular hexagon are all congruent and measure 120 degrees.

Next, we can see that the given angle (11x + 21)° is an interior angle of the hexagon. Therefore, we can set this angle equal to 120 degrees and solve for x:

11x + 21 = 120

11x = 99

x = 9

Therefore, the value of x is 9.

Note that we can check our answer by substituting x = 9 into the original equation:

11x + 21 = 11(9) + 21 = 120

Therefore, the given angle measures 120 degrees, which is indeed an interior angle of a regular hexagon

Shaun ordered 7 tacos and 8 burritos, for a total of 160160 calories from tacos and 320320 calories from burritos.

To solve this problem, we need to use a system of equations. Let's call the number of tacos Shaun ordered x and the number of burritos he ordered y. We can then write the following equations:

160x + 320y = 3680 (the total number of calories consumed)
x + y = 15 (the total number of items ordered)

We can rearrange the second equation to get y = 15 - x and then substitute that into the first equation to solve for x:
160x + 320(15 - x) = 3680
160x + 4800 - 320x = 3680
-160x = -1120
x = 7

Now that we know x, we can plug it back into the second equation to solve for y:
7 + y = 15
y = 8

First, we need to find the radius of the pipe by dividing the diameter by 2:

radius = 3ft / 2 = 1.5ft

Next, we can use the formula for the volume of a cylinder:

V = πr²h

where V is volume, π (pi) is approximately 3.14, r is the radius, and h is the height (or length) of the cylinder.

Plugging in the values we have:

V = 3.14 x (1.5ft)² x 17ft

V = 3.14 x 2.25ft² x 17ft

V = 3.14 x 38.25ft³

V ≈ 120ft³

The cylindrical pipe's volume is about 120 cubic feet.

The volume of the silo is approximately 9,685.73 cubic feet.

What is volume of a cylinder?

The volume of a cylinder can be calculated using the formula:

[tex]V = \pi r^2h[/tex]  where V is the volume, r is the radius of the base of the cylinder, and h is the height of the cylinder.

We are given that the diameter of the silo is 17 feet. The radius, which is half the diameter, is therefore:

r = 17/2 = 8.5 feet

We are also given that the height of the silo is 42 feet.

Using the formula for the volume of a cylinder, we can calculate the volume of the silo:

The Fundamental Homomorphism Theorem states that for any homomorphism f from a ring A to a ring B, the kernel of f (the set of elements of A mapped to the identity of B) is an ideal of A. Applying this to the given problem, let A be a commutative ring and f:A→A be the homomorphism f(x)=x2. The kernel of f is J = {x∈A:x2=0}. Then J is an ideal of A.

To prove that (x+y)2=x2+y2 for all x,y∈A, consider (x+y)2 = (x+y)(x+y) = x2 + xy + yx + y2. Since A is commutative, xy=yx and so (x+y)2=x2+2xy+y2. Since 2xy=2yx, then (x+y)2=x2+y2, as desired.

Now, we can conclude that f is a homomorphism from A to A. In addition, B={x2;x∈A} is a subring of A, since for all x,y∈A, (x+y)2=x2+y2 and so x2+y2∈B. Moreover, since J is an ideal of A, A/J≅B.
