Answer:

x= (2w + 10y)/5 or  \(\frac{ 2w + 10y}{5}\)

Step-by-step explanation:

w = 5(x/2 - y)

w/5 = x/2-y

w/5 + y =x/2

( 2w/5 )+2y=x

x= (2w + 10y)/5

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 simplified form of the expression -6w + (–8.3) + 1.5+ (–7w) is -13w - 6.8.

Given the expression in the question;

-6w + (–8.3) + 1.5+ (–7w)

To simplify, first remove the parenthesis

Note that;

-6w + × - 8.3 + 1.5 + × - 7w

Step-by-step explanation:

Given

Solution

The x-intercept of the function g(x) = -5(x - 3)^2 is (3, 0) and the vertex of the function g(x) = -5(x - 3)^2 is (3, 0)

The function is given as:

g(x) = -5(x - 3)^2

Set g(x) to 0, to determine the x-intercept.

-5(x - 3)^2 = 0

Divide through by -5

(x - 3)^2 = 0

Take the square root of both sides

x - 3 = 0

Add 3 to both sides

x = 3

Hence, the x-intercept of the function g(x) = -5(x - 3)^2 is (3, 0)

The function is given as:

g(x) = -5(x - 3)^2

A quadratic function is represented as:

Where, the vertex is

Vertex = (h, k)

By comparing g(x) = a(x - h)^2 + k and g(x) = -5(x - 3)^2, we have

If you look at the place values, that will help you determine the standard form. Hope this helps!

The values of the z-statistic that are statistically significant at the alpha=0.005 level are greater than 2.576.

To determine the values of the z-statistic that are statistically significant at the alpha=0.005 level for testing the hypothesis H₀: μ = 0 against Hₐ: μ > 0, we need to find the critical value from the standard normal distribution.

The critical value corresponds to the z-score that marks the boundary of the rejection region. In this case, since the alternative hypothesis is one-sided (μ > 0), we are interested in the right-tail of the distribution.

The alpha level of 0.005 indicates that we want to reject the null hypothesis at a significance level of 0.005, which corresponds to a 0.5% area in the right tail of the standard normal distribution.

Using a standard normal distribution table or a calculator, we can find the z-score that corresponds to an area of 0.005 in the right tail. The z-score that corresponds to an area of 0.005 is approximately 2.576.

Thus, the values of the z-statistic that are statistically significant at the alpha=0.005 level are greater than 2.576.

If the calculated z-statistic for the sample falls in the rejection region (greater than 2.576), we can reject the null hypothesis H₀: μ = 0 in favor of the alternative hypothesis Hₐ: μ > 0 at the alpha=0.005 level of significance.

Answer:

$526.3 is the monthly payment

Step-by-step explanation:

We use the compound interest formula to calculate the total amount payable on the loan.

Mathematically;

A = P(1 + r/n)^nt

Where A is the amount to pay

P is amount borrowed = 22,000

r is interest rate = 7.25/100 = 0.0725

t is years = 5 years

n is the number of times we compound lee year = 12 times since it’s monthly

Substituting these values, we have

A = 22,000(1 + 0.0725/12)^(12)(5)

A = 22,000(1 + 0.006041666666667)^60

A = $31,578

Monthly payment is total amount/ number of months

There are sixty months in 5 years

So monthly payment is 31578/60 = $526.3

The number of subs in the order is 8 or 9

Let's call the number of subs in the order "x".

Since the cost of 3 subs is $20, the cost per sub is $20 / 3 = $6.67.

And since the cost of 4 subs is $26, the cost per sub is $26 / 4 = $6.50.

So the cost per sub is between $6.50 and $6.67.

If the total cost is $56, then the cost per sub must be $56 / x.

The integral of 1 x^2 is a mathematical concept used to find the area under the curve of the function f(x) = x^2, and is equal to (1/3)x^3 + C, where C is an arbitrary constant of integration.

An integral is a mathematical concept used to find the area under a curve, or the accumulation of quantities that change continuously over time. The indefinite integral of x^2 can be found using basic integration rules and techniques.

In simple terms, an integral can be thought of as the sum of infinitely many small rectangles, each with a height equal to the value of a function at a certain point and a width equal to a small change in the independent variable. The integral of 1 x^2 refers to the indefinite integral of the function f(x) = x^2, where x is the independent variable. The purpose of finding the indefinite integral is to determine the general form of the function whose derivative is the original function. The result of indefinite integral of x^2 is: ∫ x^2 dx = (1/3)x^3 + C, where C is an arbitrary constant of integration. So, when finding the indefinite integral of 1 x^2, you can see that it represents the area under the curve of the function f(x) = x^2. The constant of integration, C, can be used to represent the fact that the indefinite integral of a function is not unique and depends on the choice of the lower and upper limits.

Where the transversal crosses parallel lines at some angle not a right angle, all of the acute angles are congruent, and all of the obtuse angles are congruent. The acute angles are (obviously) not congruent with the acute angles. Any acute angle is supplementary to any obtuse angle.

Since angles 5 and 6 are a linear pair, the angle relationships of the parallel lines are irrelevant. A linear pair of angles is supplementary.

The speed of the plane with no wind is 150 mph.

Let's call the speed of the plane with no wind "x".

When the plane is flying into a 30mph headwind, its effective speed is reduced by 30mph. So the plane's speed relative to the ground is x - 30mph.

Similarly, when the plane is flying with a 30mph tailwind, its effective speed is increased by 30mph. So the plane's speed relative to the ground is x + 30mph.

Let's use the formula: distance = rate × time, where "distance" is the same in both cases since the plane covers 200 miles and 300 miles respectively. We can set up two equations

200 = (x - 30) × t

300 = (x + 30) × t

where "t" is the time it takes the plane to cover each distance.

We can solve for "t" in the first equation

t = 200 / (x - 30)

Then we can substitute this expression for "t" into the second equation

300 = (x + 30) × (200 / (x - 30))

Simplifying this equation, we get

300(x - 30) = 200(x + 30)

Expanding both sides, we get

300x - 9000 = 200x + 6000

Subtracting 200x from both sides and adding 9000 to both sides, we get

100x = 15000

Dividing both sides by 100, we get

x = 150 mph
