The price of an item has been reduced by 85%. The original price was $77.

Answers

Multiply the original price by the decimal form of the percent and subtract that from the original price.
77*0.85=65.45
77-65.45=11.55
Answer: New price is $11.55
Made percent in a decimal form - 0.85 then multiply 0.85 and 77
.85*77= 65.45
Then 77.00 subtract by 65.45

In the polynomial below, what number should replace the question mark to produce a difference of squares?

Answers

A polynomial is an algebraic equation that consists of more than one term. Otherwise, it is called a monomial. The technique in producing a difference of the squares is completing of the squares method. For a quadratic formula with a general form of ax2 + bx + c = 0, you can determine c such that the formula could be factored into two monomials. The equation would be (b/2)^2.

For example, if the equation is x^2 + 2x+ __ = 0, c is solved as follows:

c = (2/2)^2 = 1

The equation would be x^2 + 2x +1 = 0. When you simplify and factor it out, the equation would become (x+1)^2 = 0.

How do you add subtract multiply and divide complex numbers and polynomials

Answers

A complex number is the sum (or difference) of two parts: real and imaginary.To add or subtract two complex numbers, need to add\subtract separately the real part and imaginary separately. In the end, you will receive the imaginary and real part of the result. 

More difficult to divide complex numbers. 1. We must find the complex conjugate of the denominator 2. Then, we must multiply the numerator and denominator by that conjugate and simplify the expression.The complex conjugate have the part equal to given, and the imaginary part is opposite to given.

To multiply complex numbers, we must multiply it like the two expressions in brackets, and simplify the result.

Addition subtraction and multiplication of polynomials is also made as expressions in parentheses between them. During the operation it is necessary to cause such members.To divide the polynomial by the polynomial you need to record them so as if you divide the numbers in a column, and perform the division by the same rules. 

Final answer:

To operate on complex numbers, add or subtract real and imaginary parts separately, multiply using the distributive property, and divide by multiplying by the conjugate of the denominator. Polynomial operations similarly involve combining like terms, using the distributive property, and performing long or synthetic division.

Explanation:

Adding, Subtracting, Multiplying, and Dividing Complex Numbers and Polynomials

To add complex numbers, combine the real parts and the imaginary parts separately. For example, (3 + 2i) + (1 + 4i) = (3 + 1) + (2i + 4i) = 4 + 6i. For subtracting complex numbers, similarly subtract the real and imaginary parts: (3 + 2i) - (1 + 4i) = (3 - 1) + (2i - 4i) = 2 - 2i.

To multiply complex numbers, use the distributive property (FOIL), and remember that i² = -1. For instance, (3 + 2i)(1 + 4i) = 3 + 12i + 2i + 8i² = 3 + 14i - 8 = -5 + 14i.

For dividing complex numbers, multiply the numerator and the denominator by the conjugate of the denominator to rationalize it. For example, (3 + 2i) ÷ (1 + 4i), multiply numerator and denominator by (1 - 4i) to get [(3 + 2i)(1 - 4i)] ÷ [(1 + 4i)(1 - 4i)] = (3 - 12i + 2i - 8i²) ÷ (1 - 16i²) = (11 - 10i) ÷ 17 = (11÷ 17) - (10i÷ 17).

Polynomial operations are similar, but instead of imaginary units, we work with variables. For adding polynomials, combine like terms. For subtracting polynomials, change the sign of each term in the polynomial being subtracted and combine like terms. Multiplying polynomials also requires the distributive property, and for division, you can use either long division or synthetic division depending on the polynomials involved.

−5r+8r+5

Answers

-5r+8r=3r then you add the 5 to the 3r because you cannot add them if it does both have the r. the answer is 3r+5
-5r + 8r + 5

We must combine like terms.

That basically just means that we add anything that has any like variables :)

In this case, our like terms are the variable "r."

So, we must add -5r to 8r

Think of this as if there were no "r" in there.

So, it looks like this : -5 + 8

What's -5 + 8?

It's 3! So, now we just need to add an 'r' after the 3.

So, -5r + 8r = 3r

Since we have no more like terms, our answer is :

3r + 5

identify the following probability as theoretical or empirical. After tossing the same coin 10 times, you are surprised to find that tails has come up 8 times. You therefore conclude that this coin is not fair and that the probability of getting tails with this coin is 0.80. A. Empirical B. Theoretical

Answers

Answer:

A. Empirical

Step-by-step explanation:

Theoretical probability is defined as a probability which is based on reasoning. This is written in a ratio form - of the number of favorable outcomes to the number of possible outcomes.

And the empirical probability gives an estimation of an event occurring based on how often that event occurred after collecting the data from large number of trials.

So, based on the definitions, the given scenario is empirical or experimental probability.

Boundary Peak in Nevada is 13,000 feet high. Guadalupe Peak in Texas is 8,749.75 feet high. How much higher than Guadalupe Peak is Boundary Peak? Round your answer to match the less precise measurement.

Answers

4250.25
this is the correct answer all you need to do is round it. Hope this helps!

Answer:

The Boundary peak is 48.58% higher than Guadalupe peak.

Step-by-step explanation:

Givens:

Boundary Peak is 13,000 ft high.Guadalupe Peak is 8,749.75 high.

To know how much higher is Boundary Peak than Guadalupe peak, we only need to subtract:

Boundary Peak - Guadalupe peak = 13,000 - 8,749.75 = 4250.25 m.

However, the best way to represent this is to express it in percentage. To do that, we need to use the rule of three. If 100% is 8749.75, what percentage would be 13000:

[tex]13000m\frac{100\%}{8749.75m}=148.58 \%[/tex]

Therefore, the Boundary peak is 48.58% higher than Guadalupe peak.

How to factor a polynomial when the leading coefficient isn't 1

Answers

You cant... The leading coefficient has to be a whole number, bigger than one

Final answer:

To factor a polynomial with a leading coefficient that isn't 1, use the ac method or factoring by grouping, identify common factors, and check your work by expanding the factors.

Explanation:

When factoring a polynomial with a leading coefficient that isn't 1, you should consider each term, and factor out any common factors first. If the polynomial is a quadratic, for instance, with a leading coefficient greater than 1, you can use techniques such as the ac method or factoring by grouping. The ac method involves finding two numbers which multiply to give you the product of the leading coefficient and the constant term, and add up to the middle term's coefficient. Once you have these numbers, you can rewrite the middle term and then factor by grouping.

Step-by-Step Explanation

Identify the leading coefficient, the constant term, and the middle term's coefficient.Find two numbers that multiply to the product of the leading coefficient and the constant term, and add to the middle term's coefficient.Rewrite the middle term using the two numbers found in step 2, splitting it into two terms.Factor by grouping, which involves pairing off the terms in such a way that they have a common factor, and then factoring out the greatest common factor from each pair.If you have factored correctly, you should be able to factor out an additional term from the resulting expression, resulting in a factored polynomial.Simplify further if possible, and check your answer by expanding the factors to ensure you get the original polynomial.
