What is the solution for 3 1/4 + 3/8

The polynomial that must be added to x^(2)-2x+6 is 2x^(2) + 9x - 6.

To find the product of the two polynomials (2x^(4)y)(3x^(5)y^(8)), we need to use the distributive property and combine like terms.

The distributive property states that a(b+c) = ab+ac. So, we can distribute the first polynomial to each term in the second polynomial:

(2x^(4)y)(3x^(5)y^(8)) = (2x^(4)y)(3x^(5)) + (2x^(4)y)(y^(8))

Next, we can combine like terms by adding the exponents of the variables:

= 6x^(4+5)y^(1+8)

= 6x^(9)y^(9)

So, the product of the two polynomials is 6x^(9)y^(9).

To find the polynomial that must be added to x^(2)-2x+6 so that the sum is 3x^(2)+7x, we can set up an equation:

x^(2)-2x+6 + (a+bx+cx^(2)) = 3x^(2)+7x

Then, we can rearrange the equation to solve for the polynomial:

a+bx+cx^(2) = 3x^(2)+7x - x^(2) + 2x - 6

a+bx+cx^(2) = 2x^(2) + 9x - 6

Therefore, it would be necessary to take the measurements in a manner that would guarantee that these requirements are met.

Two or more lines, dotted lines, or planes that remain the same distance apart and never cross, even if they are extended indefinitely in both directions, are referred to as parallel in mathematics. The sign "||" stands for parallel lines. There are many significant characteristics of parallel lines. The fact that a transversal line—a line that crosses two or more parallel lines—always forms equal angles is among the most significant.

given

If two lines are drawn, one from the highest spot on the roof to the surface and the other from the lowest point, they must be parallel to one another. Those lines must also be parallel to one another if we sketch one from the leftmost point on the roof to the surface and another from the rightmost point on the roof to the surface.

Therefore, it would be necessary to take the measurements in a manner that would guarantee that these requirements are met.

To ensure that the measurements are precise and that the roof is built at the right angle to be parallel to the road, this may require using a level or other instruments.

The steepest road in the world, Canton Avenue in Pittsburgh, Pennsylvania, has a grade of 37%. This means that for every 100 ft of horizontal distance, the road rises 37 ft. To find out how much the road rises for 21 ft of horizontal distance, we can use the formula:

rise = grade × distance

Plugging in the values we have:

rise = 0.37 × 21

rise = 7.77 ft

Therefore, the road rises 7.77 ft for 21 ft of horizontal distance.

To find the angle that this grade makes with the ground, we can use the formula:

tan θ = rise ÷ distance

Plugging in the values we have:

tan θ = 7.77 ÷ 21

tan θ = 0.37

θ = tan^-1(0.37)

θ = 20.3°

Therefore, the grade of Canton Avenue makes an angle of 20.3° with the ground.

One possible ordered pair that is a solution of the equation y = 22 - 9x is (2, 4).

What is an ordered pair, and how can we find solutions of a linear equation?

An ordered pair is a pair of numbers (x, y) that represents a point on a coordinate plane. In algebra, we often use ordered pairs to represent solutions of equations, where the x-coordinate represents a variable and the y-coordinate represents the corresponding value of the expression.

To find solutions of a linear equation, we can substitute different values of the variable into the equation and solve for the corresponding values of the expression.

Find the ordered pair:

We are given the equation y = 22 - 9x, and we want to find an ordered pair that is a solution of the equation. To do this, we can choose a value of x and then use the equation to find the corresponding value of y.

Let's choose x = 2. Then, we can substitute x = 2 into the equation and solve for y:

y = 22 - 9(2)

y = 22 - 18

y = 4

Therefore, when x = 2, y = 4, which means the ordered pair (2, 4) is a solution of the equation.

We could also check this by graphing the equation and verifying that the point (2, 4) lies on the line represented by the equation.

If the constant of variation is 12 and y = 36 and they vary directly, then x equals 3.

Direct variation is when two quantities, x and y, are related in such a way that the ratio of their values is always the same. This means that y = kx, where k is the constant of variation.

In this case, we are given that k = 12 and y = 36. We can plug these values into the equation to find x:

36 = 12x

To solve for x, we can divide both sides of the equation by 12:

36/12 = 12x/12

g(x)=810(1/9)ˣ

The following is the formula for an exponential function that traverses two points:

f(x) = abˣ

Where a is the initial value and b is the growth rate.

To find the formula for an exponential function that passes through the two points given, we can plug in the values of x and y into the formula and solve for a and b.

For the first set of points, (0,4) and (2,64), we can plug in the values of x and y into the formula and solve for a and b:

4 = ab⁰
64 = ab²

Simplifying the first equation gives us:

a = 4

Substituting this value of a into the second equation gives us:

64 = 4b²

Solving for b gives us:

b = √(64/4) = 4

Therefore, the formula for the exponential function that passes through the two points (0,4) and (2,64) is:

f(x) = 4(4ˣ)

Answer:

Step-by-step explanation:

You want the missing diameter of the smaller of two similar cylinders, where the larger is 12 ft in diameter and 3 ft high, while the smaller is 8 inches high.

The linear dimensions of similar figures have the same ratio.

The ratio of the diameter to the height of the larger figure is ...

  (12 ft)/(3 ft) = 4

The smaller figure will also have a diameter that is 4 times the height:

  d = 4 × 8 in = 32 in

The missing dimension is 32 inches.

Answer:

(x, y) = (-7, -2).

Step-by-step explanation:

To solve the system of equations:

y = 3x + 19

y = 5x + 33

We can use the substitution method, which involves solving one equation for one variable and substituting that expression into the other equation. Then we can solve for the remaining variable.

From the first equation, we can solve for y in terms of x:

y = 3x + 19

From the second equation, we can solve for y in terms of x:

y = 5x + 33

Now we can substitute the expression for y from the first equation into the second equation:

3x + 19 = 5x + 33

Simplifying this equation by subtracting 3x from both sides:

19 = 2x + 33

Subtracting 33 from both sides:

-14 = 2x

Dividing both sides by 2:

x = -7

Now that we have the value of x, we can substitute it back into either equation to find the value of y:

y = 3x + 19

y = 3(-7) + 19

y = -21 + 19

y = -2

The solution to the system of equations is (x, y) = (-7, -2).

Step-by-step explanation:

You want the area of triangle RST using the area formula A=1/2bh, given the points R(-2, 7), S(-5, 1), and T(7, -5).

A plot of the points is shown in the first attachment. By counting grid squares, you can see that segment RS has a "rise" of 2 grid squares for each 1 to the right. The total (run, rise) is ...

  R -S = (-2, 7) -(-5, 1) = (-2 +5, 7 -1) = (3, 6)

The length of RS is found using the Pythagorean theorem (distance formula). It is ...

  RS = √(3² +6²) = √45 = 3√5

Similarly the length of segment ST is ...

  T -S = (7, -5) -(-5, 1) = (7 +5, -5 -1) = (12, -6)

  ST = √(12² +(-6)²) = √180 = 6√5

We note that the slopes of these segments are opposite inverses of each other:

  slope RS = 6/3 = 2

  slope ST = -6/12 = -1/2

This means the segments are at right angles. One of them can be considered to be the "base" and the other the "height" of the triangle.

Using the area formula, we find the area to be ...

  A = 1/2bh

  A = 1/2(6√5)(3√5) = (1/2·6·3)(√(5·5)) = 9·5 = 45

The area of ∆RST is 45 square units.

Alternate solution

When the coordinates of a polygon are given, there are several other ways to find its area. One of these is illustrated in the second attachment.

The method illustrated here computes successive "determinants", then finds the area as half the absolute value of their sum. (The sign of the sum will depend on the order in which the points are listed around the figure. Here, it is counterclockwise.) As you can see, we get the same result. You can also see that a spreadsheet is useful for doing the repetitive math.

  Area ∆RST = 45 square units

__

Additional comment

The distance formula for the length of the segment between two points is ...

  d = √((x2-x1)² +(y2-y1)²)

Above, we calculated the differences (x2-x1, y2-y1) separately, then used the "root sum squares" formula for the distance. This has the advantage that (y2-y1)/(x2-x1) is the slope of the segment, and we needed to make sure the segments were perpendicular.

The restrictions on x are x = 1/5 and x = 0.

The restrictions on x, when (x+4)/(5x-1) is divided by (3x+12)/(6x), can be found by looking at the denominators of each fraction. The restrictions are values of x that would make the denominator equal to zero, which would make the fraction undefined.

For the first fraction, (x+4)/(5x-1), the restriction is when 5x - 1 = 0. Solving for x, we get:
5x = 1
x = 1/5

For the second fraction, (3x+12)/(6x), the restriction is when 6x = 0. Solving for x, we get:
x = 0

Therefore, the restrictions on x are x = 1/5 and x = 0. These values of x cannot be used in the original expression because they would make the denominator equal to zero and the expression undefined.

To subtract the two fractions, we need to find a common denominator. The least common denominator (LCD) is the least common multiple of the denominators of two or more fractions, and it is used to find a common denominator so that we can perform operations on them. The LCD of 12vx² and 8v²x is 24v²x². We can then multiply each fraction by the LCD to get the same denominator and subtract the numerators.

(7)/(12vx²) x (24v²x²)/(24v²x²) - (3)/(8v²x) x (24v²x²)/(24v²x²) = (14v)/(24v²x²) - (9x)/(24v²x²) = (14v - 9x)/(24v²x²)
