if the perimeter of a rectangle measures 50 feet and the length of the rectangle is 17 feet, what is the width

Since this equation must hold for all values of x, we can substitute x = i and x = -i to get two equations: 2A + 3i = -5i=> 2A - 3i = 5i=> A = -3/2Therefore, A is equal to -3/2.

A polynomial is a mathematical statement with coefficients and uncertainty that uses only additions, subtractions, multiplications, and powers of positive integer variables. There is just one indeterminate x polynomial identified by the formula x2 4x + 7. The term "polynomial" refers to an expression in mathematics that consists of variables (sometimes referred to as "indeterminates") and coefficients that may be added, subtracted, multiplied, and raised to negative integer powers of non-variables. A polynomial is an algebraic expression having variables and coefficients. Only addition, subtraction, multiplication, and non-negative integer exponents are permitted in expressions. The word for these expressions is polynomials.

To find A, we need to perform polynomial long division of P(x) by \(x^2 + 1\)and get the remainder equal to -5x.

          x

   --------------

\(x^2 + 1 | x^3 + 3x^2 - 2Ax + 3\)

         \(x^3 + 0x^2 + x\)

          --------------

               \(3x^2 - 2Ax\)

           \(3x^2 + 0x - 3i\)

                ------------

                    \(2Ax + 3i\)

                \(2Ax + 0x - 2iA\)

                       -----------

                        \(3i + 2iA\)

The remainder of the division is (2A + 3i) when the divisor is \(x^2 + 1\). We know that this remainder is equal to -5x, so we can set up the equation:

2A + 3i = -5x

Since this equation must hold for all values of x, we can substitute x = i and x = -i to get two equations:

2A + 3i = -5i

2A - 3i = 5i

A = -3/2

Therefore, A is equal to -3/2.

The value of x that makes lines u and v parallel is 6. Option A is correct.

First, let us understand the angles formed by parallel and transversal lines:

The different types of angles are alternate exterior angles, alternate interior angles, corresponding angles, consecutive angles, etc.

From the picture attached,

If the lines u and v are parallel and a third line (transversal) is intersecting these lines at two distinct points,

Both the angles given in the picture will be equal in measure as these angles are alternate exterior angles if u and v are parallel.

20x + 10 = 130 degrees

20x = 130 - 10 degrees

x = 120 / 20 = 6

So, the value of x is 6.

Thus, the value of x that makes lines u and v parallel is 6. Option A is correct.

Answer:

estimate

Step-by-step explanation:

because when we estimate it will give us a value close to the exact value.

Answer:

Options (1), (2), (3)

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

Here m = slope of the line

b = y-intercept

Given line on the graph is passing through two points (-3, 0) and (0, 1).

Slope of this line will be,

m = \(\frac{y_2-y_1}{x_2-x_1}\)

   = \(\frac{1-0}{0+3}\)

   = \(\frac{1}{3}\)

y-intercept of the line 'b' = 1

Equation of the line will be,

y = \(\frac{1}{3}x+1\)

If the points given in the options satisfy the equation, they will be the solution of the line.

Option (1),

For (3, 2),

2 = \(\frac{3}{3}+1\)

2 = 2

True.

(3, 2) is the solution.

Option (2)

For (21, 8),

8 = \(\frac{21}{3}+1\)

8 = 8

True.

(21, 8) is the solution.

Option(3)

For (-15, -4),

-4 = \(\frac{-15}{3}+1\)

-4 = -4

True.

(-15, -4) is the solution.

Option (4)

For (12, 9)

9 = \(\frac{12}{3}+1\)

9 = 5

False

(12, 9) is not the solution.

Option (5)

For (-6, 1)

1 = \(\frac{-6}{3}+1\)

1 = -1

False

(-6, 1) is not the solution.

Therefore, Options (1), (2), (3) are the solutions.

The function f(x) = 12-49 22 +42-21 has a removable discontinuity at a specific x-value. To find this x-value, we need to identify where the function is undefined or where it has discontinuity that can be removed.

To determine the x-value of the removable discontinuity, we need to examine the function f(x) = 12-49 22 +42-21 and look for any bor points where the function is not defined. In this case, the expression 22 +42-21 involves division, and division by zero is undefined.

To find the x-value of the removable discontinuity, we set the denominator equal to zero and solve for x. In the given function, the denominator is not explicitly shown, so we need to determine the expression that results in division by zero. Without further information or clarification about the function, it is not possible to determine the specific x-value of the removable discontinuity.

Answer:

10.2%

Step-by-step explanation:

The given population of the village in 2017 = 7,500

The given population of the village in 2019 = 8,265

The percentage increase in the population of the village from 2017 to 2019 is given by the following percentage increase formula;

\(Percentage \ increase = 100 \times \dfrac{Final \ value - Initial\ value}{Initial \ value}\)

The final value of the population in 2019 = 8,265

The initial value of the population in 2017 = 7.500

Therefore;

\(Percentage \ increase \ in \ the \ population = 100 \times \dfrac{8,265 - 7,500}{7,500} = 10.2 \%\)

The percentage increase in the population = 10.2%

The correct description is that moon is waxing.

The theory used in this question is the lunar cycle, which is the process by which the moon changes its shape and illumination over the course of a month.

The waxing phase of the lunar cycle is when the moon is gradually getting bigger and more illuminated.

The waning phase is when the moon is gradually getting smaller and less illuminated.

The moon is waxing:

This is an accurate description because when the moon changes from a new moon to a full moon, it is said to be waxing.

This means that the moon is gradually getting bigger, and its illuminated side is increasing.

This process is called the waxing phase of the moon's cycle.

Rational numbers are integers and fractions.

Irrational numbers are numbers that cannot be expressed as fractions, such as π.

Now, \(\bf{\sqrt{25}}\) can be simplified to 5 or -5; both of which are rational numbers.

The true statements are:

The initial cost for manufacturing records is $454, regardless of the number of records ordered.

In addition to the initial cost, each record costs $0.90 to manufacture.

Each record costs a total of $454.90 to manufacture.

As according to the question the function f(x)= 454+0.9x gives the cost, in dollars, of manufacturing x vinyl records.

Step-by-step explanation:

Answer:

Part 1 d/a = a/f

d/b = b/c

e/c = c/f

Explanation:

The triangles are similar.

This is about equal proportion. Look at the relationship between the short leg to the hypotenuse, short leg to long leg, and long leg to hypotenuse.

Part 2:

78

Explanation:

Calculate x, then substitute to get the lengths of the sides. Given equal angles, the two sides are equal.

5x –19 = 2x +11

3x = 30

x= 10

5(10) –19 = 31

2(10) + 11 = 31

Add the three sides: 31 +31 +16 = 78

Part 3:

Sin A= Cos B. both are a/b

Sin C= Cos A both are c/b

Sin C = c/b

Explanation:

Remember S=o/h, C=a/h , T=o/h

Look at the relationship of the sides to the angles given. If the sides match, the statement is true.

Sine of angle A is side a to side b. This is opposite/hypotenuse

Cosine of angle B is side a to side b This is adjacent/hypotenuse.

The lengths a and b are used in both. The hypotenuse don't change, but whether a side is considered an opposite or an adjacent depends on which angle you are looking at.

This can be confusing, but the more you practice, the easier it gets.

I hope this helps!
