The size of a bicycle is determined by the diameter of the wheel. You want a 24-in bicycle for Christmas. What is the circumference of one of the wheels? A 75.4 in B 75.3 in C 37.7 in D 37.6 in

Answers

Answer 1
Answer:

The circumference of one of the wheels is:  

                     Option: A    75.4 in.

Step-by-step explanation:

The 24-in bicycle means that the diameter of the wheel of the bicycle isL 24 in.

We know that the wheel of the bicycle is in the shape of a circle.

This means that the diameter of circle is: 24 in.

Hence, the radius(r) of circle is: 12 in.

( since we know that the radius(r) of the circle is half the diameter(d) of the circle)

Now, we are asked to find the circumference of the circle.

The circumference(C) of the circle is given by:

C=2πr

i.e.

C=2×3.14×12

i.e.

C=75.36 in.

which to the nearest tenth is: C=75.4 in.

1. Explain a method of determining the correct degree and classification of a polynomial.

2. Why is the polynomial, 4x^2y + 5xy classified as a 3rd degree binomial?

Answers

A polynomial can be classified according to the number of expressions that it has in a given equation. A monomial has only one expression having a coefficient (number) and a variable (letter). A binomial has two expressions, same as the definition of the monomial. And a trinomial has three expressions, same as the definition of a monomial. We can determine the degree of a polynomial by looking at the exponents of the given polynomial. If an expression has two variables with different exponents, you can add their exponent to determine their degree.

So the polynomial, 4x²y + 5xy is classified as a 3rd degree binomial because the first term, 4x²y has a variables x² and y. The x² has an exponent 2 and y has an exponent 1. Adding the two makes it three.

Zeus Industries bought a computer for $2857. It is expected to depreciate at a rate of 24% per year. What will the value of the computer be in 3 years?

Round to the nearest penny. Do not type the "$" sign in your answer


******PLEASE HELP******

Answers

This is an exponential growth/decay problem, and it doesn't really matter which when it comes to the equation because they are both pretty much the same. The formula is A = Pe^(rt), where A is what you end up with, P is the principle value of the object, e is euler's number, r is the rate of decay or growth, and t is the time in years. Since we are looking at depreciation or decay, our r value will be negative. A is what we are solving for (the ending value), P is 2857, r is -.24 and t is 3. So our formula, set up properly, looks like this: A = 2857e^(-.24*3). The first thing to do is to simplify the exponents by multiplying them: A = 2857e^(-.72). Now we're ready to solve! On your calculator, you have a 2nd button and a LN button, when you hit 2nd-->LN you'll get e^(  .  Enter in the -.72 and then hit enter.  You should get .4867522. Now multiply that by 2857 and you'll get 1390.65.  That's what the computer will be worth in 3 years if it depreciates at that rate.

What does it mean when a greater than sign is underlined?

Answers

When a sign has the underline, it means it is also equal to. 
for example,
x [tex] \geq [/tex] 10
so the solution for "x" is greater than or equal to 10

hope this helps!
Final answer:

An underlined greater than sign in mathematics represents a strict inequality, indicating that one value is significantly greater than another.

Explanation:

In mathematics, an underlined greater than sign usually represents an inequality. When a greater than sign (>) is underlined, it indicates a strict inequality, meaning that the value on the left side is significantly greater than the value on the right side.

For example, if we have the underlined inequality 5 > 3, it means that 5 is larger than 3 and there is a clear distinction between the two values.

It's important to note that this is just one possible interpretation of an underlined greater than sign, as the context in which it is used can vary.

eight times the sum of a and b

Answers

Final answer:

The question concerns a basic algebraic expression 'eight times the sum of a and b' which is represented as 8(a + b). The expression emphasizes the operation order: sum first, then multiply, which results in a value eight times greater than the original sum.

Explanation:

The question 'eight times the sum of a and b' is a mathematical expression that can be represented as 8(a + b). This expression means you first add the numbers 'a' and 'b' and then multiply their sum by eight. The result you get after the multiplication will be eight times greater than the original sum of 'a' and 'b'. For instance, if 'a' is 2 and 'b' is 3, their sum is 5, and when this is multiplied by eight, it becomes 40, which is the desired expression's value.

To understand this concept further, we can refer to the exponentiation rule mentioned, which states that (xa)b = xa.b. Although this is a different type of operation—exponentiation—it demonstrates a similar principle of first performing the operation inside the parentheses and then applying the outside operation.

Finally, when performing algebraic operations, it's essential to remember that whatever you do to one side of the equation, you should do to the other side to maintain balance. This is a fundamental principle in algebra that helps to solve equations, such as the example provided showing how to isolate 'a' by subtracting 'x' from both sides of the equation a b.

For an angle θ with the point (–20, –21) on its terminating side, what is the value of cosine?

Answers

The fact that the terminating side has 2 negative values tells us that it lies in Q3, where both x and y are negative. The cosine of an angle is the side adjacent/hypotenuse. But we don't have the value for the hypotenuse, so we have to find it using the Pythagorean Theorem. c^2 = -20^2 + -21^2  which gives us a c value of 29. Now that we have the hypotenuse length, we can set up the angle's cosine value: cos theta = -20/29.

What must be true of f(x) and g(x) if both are antiderivatives of f(x)?

Answers

For a function f(x) to be anti-derivative of F(x), f'(x) should be equal to F(x).
Similarly, for g(x) to be anti-derivative of F(x), then g'(x) should be equal to F(x).

From this we can deduce that for both f(x) and g(x) to be anti-derivatives of F(x), then f'(x) should be equal to g'(x) 

They can differ only by a constant is true of f(x) and g(x) if both are antiderivatives of f(x) Hence, option D is correct.

When two functions, F(x)  and G(x), are antiderivatives of the same function f(x), it means that their derivatives are equal to f(x).

This relationship can be represented as:

F'(x) = G'(x) = f(x)

However, it's important to note that if  F(x) and G(x) are both antiderivatives of F(x), then their difference, F(x) - G(x), will have a derivative of zero.

Consequently, F(x) and G(x) can differ only by a constant.

So, the correct option is D.

Complete question:

What must be true of f(x) and G(x) if both of them are antiderivatives of f(x)?

In how many different ways can five elements be selected in order from a set with three elements when repetition is allowed?

Answers

There are 243 ways to select five elements in order from a set of three elements with repetition allowed.

When selecting five elements in order from a set with three elements and repetition is allowed, each selection can include any of the three elements, repeated as necessary. Here's the breakdown:

1. For the first position, there are 3 choices.

2. For the second position, there are also 3 choices, as repetition is allowed.

3. Similarly, for the third, fourth, and fifth positions, there are 3 choices each.

To find the total number of ways, we multiply the number of choices for each position:

3 choices for the first position × 3 choices for the second position × 3 choices for the third position × 3 choices for the fourth position × 3 choices for the fifth position = [tex]\(3^5 = 243\)[/tex] ways.

Therefore, there are 243 different ways to select five elements in order from a set with three elements when repetition is allowed.

The correct naswer is 21.

The number of ways to select five elements in order from a set with three elements when repetition is allowed can be represented in LaTeX as:

[tex]\binom{5+3-1}{5} = \binom{7}{5} = \frac{7!}{5!(7-5)!} = \frac{7!}{5!2!} = 21[/tex]

Explanation:

- When repetition is allowed, the problem can be treated as finding the number of ways to arrange 5 objects with 3 distinct types.

- This can be solved using the combination formula, where we choose 5 positions out of 7 (5 elements + 3 distinct types - 1).

- The binomial coefficient [tex]\binom{n}{r}[/tex] represents the number of ways to choose [tex]$r$[/tex] items from a set of [tex]$n$[/tex] items.

- In this case, we are choosing 5 positions (elements) from a set of 7 positions (5 elements + 3 distinct types - 1).

- The binomial coefficient can be expanded using factorials: [tex]\binom{n}{r} = \frac{n!}{r!(n-r)!}[/tex]

- Substituting [tex]n = 7$ and $r = 5[/tex], we get[tex]\binom{7}{5} = \frac{7!}{5!(7-5)!} = \frac{7!}{5!2!} = 21[/tex]

Therefore, there are 21 different ways to select five elements in order from a set with three elements when repetition is allowed.
