Which row of Pascal's Triangle should you use to expand the binomial (a + b)^4?
Answer:
Step-by-step explanation:
a + b)^6 will have 7 terms so you want row 6 of the triangle 1 6 15 20 15 6 1
so (a + b)^6 = a^6 + 6a^(5)b + 15a^(4)b^2 + 20a^(3)b^3 + 15a^(2)b^4 + 6ab^5 + b^6
given a = d and b = -5y

What is dependent and dependent variable?
Independent and dependent variables are interdependent.
Dependent Variable: The term "dependent variable" refers to the variable that is being measured or tested in an experiment.
The results of the participants' tests, for instance, would be the dependent variable in a study looking at how tutoring affects test scores because that is what is being measured.
If you keep in mind that the dependent variable depends on the independent variable, finding it can be simpler.
The dependent variable's variable is being measured.It might change based on additional circumstances.It is reliant on other elements.A separate variableThis isn't the same as an experiment's independent variable, which is a variable that can stand on its own. The dependent variable (test results), however, may alter depending on the independent variable (tutoring).

The revenue earned from a sporting event can be determined by the ticket price, $125 each.
Answer:
all whole numbers
all whole-number multiples of 125
Step-by-step explanation:
The domain and the range of a function is the set of input and output values of the function.
The domain is the set of all whole numbersThe range is the set of all whole numbersLet the number of tickets be x, and the revenue be y.
So, the revenue function will be:
\(\mathbf{y = 125x}\)
The number of tickets cannot be less than 0.
So, the domain of the revenue function is:
\(\mathbf{Domain = [0,\infty)}\)
The above means that, the domain is the set of all whole numbers
Similarly, the revenue cannot be less than 0.
So, the range of the revenue function is:

20p^3 + 20p^2
The binomial can be factored as\(20p^2(p + 1)\) by factoring out the common factor of\(20p^2\)from both terms.
What is an expression?An expression is a combination of numbers, symbols, and operators that represents a mathematical quantity or relationship. It can be a single number, a variable, or a combination of these with arithmetic, algebraic, or other mathematical operations.
According to the given inforamrion:To factor a binomial means to express it as the product of two or more simpler expressions. In this case, we have a binomial expression \(20p^3 + 20p^2\), which contains two terms that have a common factor of \(20p^2.\)
To factor out this common factor, we can use the distributive property of multiplication, which tells us that a(b+c) = ab + ac. Applying this property to the given expression, we can write:
\(20p^3 + 20p^2 = 20p^2(p + p)\)
Notice that we can factor out a p from the parentheses, giving:
\(20p^2(p + 1)\)
This is the factored form of the given binomial expression. It is simpler than the original expression because it contains only two factors, whereas the original expression had three terms.

PLEASE HELP! Using completing the square to solve x2-5x+3=0. Round to the nearest tenth as needed
Answer:
\(\displaystyle x_1=\frac{5+\sqrt{13}}{2}\approx4.3\text{ and } x_2=\frac{5+\sqrt{13}}{2}\approx0.7\)
Step-by-step explanation:
We are given:
\(x^2-5x+3=0\)
And we want to solve this via completing the square.
First, we will subtract 3 from both sides. This yields:
\(x^2-5x=-3\)
Next, we will factor out the leading coefficient from the left.
In this case, the leading coefficient is simply 1 so we can leave it as is.
Next, we want to add a constant that is half of the b coefficient squared.
In this case, b = -5.
Half of that is -5/2.
Squaring yields 25/4.
So, we will add 25/4 to both sides. Since our leading coefficient is 1, we don't need to multiply by anything when we add it on the right. Hence:
\(\displaystyle x^2-5x+\frac{25}{4}=-3+\frac{25}{4}\)
The left side constitutes a perfect square trinomial as shown:
\(\displaystyle (x)^2-2\Big(\frac{5}{2} \Big)(x)+\Big(\frac{5}{2}\Big)^2=-\frac{12}{4}+\frac{25}{4}\)
Factor and subtract:
\(\displaystyle \Big(x-\frac{5}{2}\Big)^2=\frac{13}{4}\)
Taking the square root of both sides gives:
\(\displaystyle x-\frac{5}{2}=\pm\frac{\sqrt{13}}{2}\)
Hence:
\(\displaystyle x=\frac{5}{2}\pm\frac{\sqrt{13}}{2}}=\frac{5\pm\sqrt{13}}{2}\)
Approximate:
\(\displaystyle x_1=\frac{5+\sqrt{13}}{2}\approx4.3\text{ and } x_2=\frac{5-\sqrt{13}}{2}\approx0.7\)

Consider the sequence t0 = 3, t1 = 3^3, t2 = (3^3)^3, t3 = ((3^3)^3)^3
, . . . defined by t0 = 3 and tn+1 = 3tn for n > 0.
What are the last two digits in t3 = ((3^3)^3)^3? Can you say what the
last three digits are? Show that the last 10 digits of tk are the same for all k > 10.
The final ten digits are 27, 81, 43, 29, 87, 61, 83, 49, 47, with the pattern repeating every ten steps.
Let us calculate the value of t3:
t1 = 3^3 = 27
t2 = (3^3)
^3 = 27^3 = 19,683
t3 = (27^3)
^3 = 19,683^3
Because exponentiation is a repeated multiplication, we can calculate the last two digits of t3 by dividing each intermediate result by 100 and taking the remainder.
For instance, the final two digits of 273 are:
(27 * 27) % 100 = 729 % 100 = 29
(27 * 29) % 100 = 783 % 100 = 83
(83 * 29) % 100 = 2427 % 100 = 27
Therefore, the last two digits of t3 = ((3^3)^3)^3 are 27.
To demonstrate that the last ten digits are the same for all k > 10, consider the pattern of the last two digits as we continue calculating tn:
t3 = 27
t4 = (3 * 27) % 100 = 81
t5 = (3 * 81) % 100 = 43
t6 = (3 * 43) % 100 = 29
t7 = (3 * 29) % 100 = 87
t8 = (3 * 87) % 100 = 61
t9 = (3 * 61) % 100 = 83
t10 = (3 * 83) % 100 = 49
t11 = (3 * 49) % 100 = 47
Every 10 steps, the last two digits repeat in a cycle. As a result, for all k > 10, the last ten digits of tk are the same. The final ten digits are 27, 81, 43, 29, 87, 61, 83, 49, 47, with the pattern repeating every ten steps.

John has a bag of marbles. He gives away 3/4 of the marbles to his friend. Later, he receives another bag containing 2/4 of the original number of marbles. How many marbles does John have now?
Answer:
Total is 3
Step-by-step explanation:
AI-generated answer
Let's start by finding out how many marbles John had initially. We can do this by using the information given in the problem.
Let the original number of marbles be x.
John gave away 3/4 of his marbles, which means he has 1/4 of the original number of marbles left. We can express this as:
1/4 x = the number of marbles John has left
If we solve for x, we get:
4/1 * 1/4 x = 4/1 * the number of marbles John has left
x = 4 * the number of marbles John has left
Now we know that John had 4 times the number of marbles he has left.
Next, John receives another bag of marbles containing 2/4 (which is the same as 1/2) of the original number of marbles.
We can express this as:
1/2 x = the number of marbles in the new bag
To find the total number of marbles John has now, we can add the number of marbles he has left to the number of marbles in the new bag:
Total number of marbles = the number of marbles John has left + the number of marbles in the new bag
Total number of marbles = 1/4 x + 1/2 x
Total number of marbles = (1/4 + 1/2) x
Total number of marbles = (3/4) x
We know that x = 4 times the number of marbles John has left, so we can substitute this into the equation:
Total number of marbles = (3/4) * 4 * the number of marbles John has left
Total number of marbles = 3 * the number of marbles John has left
Therefore, the total number of marbles John has now is 3 times the number of marbles he has left.
