And now simplify:
[tex]x^2 + 2xy^2 + y^4[/tex]
Answer:
[tex]x^{2}+y^{4}+2xy^{2}[/tex]
Step-by-step explanation:
The given expression is (x + y²)² and we have to simplify it to find the binomial expansion.
(x + y²)² is in the form of (a + b)².
When we expand (a + b)² we get the binomial expression
(a + b)² = a² + b² + 2ab
Now we put the value of a = x and b = y²
(x + y²)² = x² + (y²)² + 2(x)(y²)
= [tex]x^{2}+y^{4}+2xy^{2}[/tex]
Therefore answer is [tex]x^{2}+y^{4}+2xy^{2}[/tex]

The amount of candy left in a Halloween bucket is given by the function A(t) = 50(0.8)t where t stands for the number of minutes the candy is available and A(t) stands for the amount of candy left at any given time. How much candy is there after five minutes?
50 pieces
40 pieces
16 pieces
200 pieces
Answers
[tex]A(t)=50(.8) ^{t} [/tex]
The reason I say that is because this is an exponential decay problem, with a starting amount of 50 pieces of candy.
If that's the case, then it would look like this with a t value of 5:
[tex]A(5)=50(.8) ^{5} [/tex]
and [tex]A(5)=50(.32768)[/tex]
so the amount of candy left after 5 minutes is 16.384 or 16

What is the sum of 12 and the quantity 8 times a number k is equal to 48? It was on my math homework, it hardly makes any sence to me, please help me, whats the answer?
Answers
The question is asking for the solution to the algebraic problem 12 + 8k = 48. By isolating 'k', it is found that the value of 'k' is 4.5.
Explanation:The problem presented here belongs to the branch of algebra. It is showing a relationship between the sum, multiplication, and is presented in a typical algebraic equation format. Let's break it down:
The sum of 12 and a number (which is 8 times k) is equal to 48. This can be written in equation form as:
12 + 8k = 48
To find the value of k, we need to isolate 'k' in the equation. First, subtract 12 from both sides of the equation:
8k = 48 - 12
Then, simplify the right side:
8k = 36
Finally, divide both sides by 8 to solve for k:
k = 36 / 8
So, k = 4.5.

A. The function is inversely proportional.
B. The function is directly proportional.
C. More input results in less output.
D. More input results in more output.
Answers
Answer:
More input results in less output.
The function is inversely proportional.
Step-by-step explanation:
those two. other answer is completely wrong
If you quadruple the input of a function and the resulting output is one-fourth the original output, what may be true of the function? The correct options are A. The function is inversely proportional and C. More input results in less output.
In mathematical terms, let's consider the function as f(x), where x is the input, and f(x) is the output.
1. Option A: The function is inversely proportional.
If quadrupling the input (4x) leads to the output being one-fourth of the original output (1/4 f(x)), it implies that f(4x) = 1/4 f(x). Inverse proportionality means that as the input increases, the output decreases, and vice versa. In this case, increasing the input by a factor of 4 (4x) causes the output to reduce to one-fourth of its original value (1/4 f(x)), indicating an inverse relationship.
2. Option C: More input results in less output.
As mentioned earlier, quadrupling the input (4x) and obtaining an output of one-fourth the original (1/4 f(x)) demonstrates that increasing the input leads to a decrease in the output. When x increases, 4x (quadruple of x) will also increase, and as a result, f(4x) will be less than f(x). This aligns with the statement that more input results in less output.
It is important to understand the relationship between the input and output of a function. In this case, the given conditions indicate inverse proportionality and that increasing the input leads to a decrease in the output. Keep in mind that mathematics often deals with relationships between variables, and understanding such relationships can help solve various problems and make predictions about how a system behaves.

A car is purchased for $28,000. After each year, the resale value decreases by
35%. What will the resale value be after 3 years? Use the calculator provided and round your answer to the nearest dollar.
Answers
Using the formula for decrement, the resale value of a $28,000 car that depreciates at a 35% rate annually for three years would be roughly $10,012.
Explanation:This question is about calculating the effects of percent decrease over a period of time. Specifically, the student is asked to calculate the value of a $28,000 car, after it undergoes a 35% percent decrease in value each year for three years. This type of problem is typically solved using the formula v = p * ((1 - r)^n), where v is the final value, p is the initial value, r is the rate of decrease, and n is the number of periods. In this case, the initial value (p) is $28,000, the rate of decrease (r) is 35% or 0.35, and the number of periods (n) is 3 years. Substituting these into the formula, we can find that the resale value after 3 years is v = 28000 * ((1 - 0.35)^3) = $10,011.75. Rounding this to the nearest dollar, we get an estimated resale value of $10,012.

The area of a rectangular wall of a barn is 300 square feet. its length is 10 feet longer than twice its width. find the length and width of the wall of the barn.
Answers
L
* W = 300 sq ft
Length is 10 ft greater than twice the width.
L = 2W + 10
Substituting
(2W+10)*W = 300
2W^2 + 10W = 300
Divide both sides by 2
W^2 + 5W = 150
W^2 + 5W - 150 = 0
Factor
(W +15)(W -10) = 0
Roots are W=-15 and W=10.
A negative width is impossible, so W=10
L = 2W + 10
L = 2(10) + 10
L = 30
length = 30 feet, width = 10 feet
Check: 30*10 = 300
To find the dimensions of the barn wall, we first expressed the given information as an equation using the formula for area. After simplifying and factoring the quadratic equation, we determined the width to be 10 feet and the length to be 30 feet.
Explanation:The question involves finding the length and width of a rectangular wall when given the area and a relationship between the length and width. We know the area of the wall is 300 square feet and that the length is 10 feet longer than twice the width. Let's denote the width as 'w' and the length as 'l'. The relationship between them can be expressed as l = 2w + 10. Using the formula for the area of a rectangle, which is A = l * w, we substitute the given area and the relationship between length and width to create an equation: 300 = (2w + 10) * w.
Solving this quadratic equation:
Expand the right side: 300 = 2w^2 + 10wMove all terms to one side: 2w^2 + 10w - 300 = 0Divide by 2 to simplify: w^2 + 5w - 150 = 0Factor the quadratic: (w + 15)(w - 10) = 0Find the roots: w = -15 or w = 10 (since width can't be negative, w = 10)Substitute w back into the relationship to find l: l = 2(10) + 10 = 30Therefore, the width of the wall is 10 feet, and the length is 30 feet.

What is the square root of 26 in simplest radical form?
Answers
Final answer:
The square root of 26 in simplest radical form is just √26, as 26 has no perfect square factor. It can also be expressed as 26 raised to the power of 0.5 based on the concept of fractional powers corresponding to roots.
Explanation:
The square root of 26 in its simplest radical form cannot be simplified further as a perfect square factor because 26 is not a perfect square. However, if we apply the concept of expressing numbers as fractional powers, we can say that any number 'x' squared, written as x², is equivalent to the square root of 'x'. Thus, the square root of 26 can also be written as 26 to the power of 0.5 or 26⁰.⁵.
Expressing the concept mathematically, we can write the square root of any number 'x' as x to the power of 0.5, which is a helpful way to solve for unknown values in various equations. This idea is useful in scenarios where different roots of a number or expressions involving fractional exponents are to be calculated, and it is essential to remember that the square root is just another form of an exponent.

What is the slope and the y intercept of the line y=6x-9?

The y-intercept is: -9 ; (or, more precisely: "(-9, 0)" .
_________________________________________________
Note: The line in written in "point-slope form"; also known as:
"slope-intercept format" ; that is: " y = mx + b" ; in which:
m = slope = coefficient of "x" ;
b = "y-intercept" (or, more precisely; the value
of "x" in the "x-coordinate" of the point of the
"y -intercept).
__________________________________________________
So: Given: y = 6x - 9 ; m = slope = 6 ;
b = -9 .
__________________________________________________
Hello there! :)
This equation is written in slope-intercept form. which means we can easily idenify the slope and the y-intercept.
First of all, slope-intercept form looks like this:
y=mx+b
The letter m represents the slope, while the letter b represents the y-intercept.
Now, let's look at the values that we have.
We are given the equation of the line:
y=6x-9
We know that m is the slope; therefore, in this equation, 6 is the slope.
-9 is the y-intercept (the letter b)
Therefore, 6 is the slope and b is the y-intercept.
