Answer:
Since a Pythagorean triple is three positive integers a, b, and c such that (a^2)+(b^2)=(c^2), where a and b are the two legs, and c is the hypotenuse, first take the sum of the squares of the two legs and make an estimate. For example, 3, 4, and 5 is a Pythagorean triple since 9+16=25.

Find an nth-degree polynomial function with real coefficients satisfying the given conditions. If you are using a graphing utility, use it to graph the function and verify the real zeros and the given function value.
n=3
-2 and 9+21 are zeros
1(1)=204
=(x);
(Type an expression using x as the variable Simplify your answer)
An nth-degree polynomial function with real coefficients that satisfies the given conditions, where n = 3 and the zeros are -2 and 9 + 21, and the function value f(1) = 204, is f(x) = (x + 2)(x - (9 + 21))(x - 1).
To find the polynomial function that satisfies the given conditions, we start by considering the zeros. Since the zeros are given as -2 and 9 + 21, we can write the factors for the polynomial as (x + 2) and (x - (9 + 21)).
Next, we consider the function value f(1) = 204. This means that when x = 1, the function should evaluate to 204. To satisfy this condition, we include the factor (x - 1) in our polynomial.
Combining these factors, we have the polynomial function f(x) = (x + 2)(x - (9 + 21))(x - 1).
To verify the real zeros and the given function value, we can use a graphing utility. By graphing the function, we can observe the x-intercepts, which represent the zeros, and check if the function evaluates to 204 when x = 1.

[tex]g(f(x)) = 3x^4 + 18x^2 + 18[/tex]
f(x) and g(x) and not inverse functions
Step-by-step explanation:
Given
[tex]f(x) = 3x^2 + 9[/tex]
[tex]g(x) = \dfrac{1}{3}x^2 - 9[/tex]
Required
Determine f(g(x))
Determine g(f(x))
Determine if both functions are inverse:
Calculating f(g(x))
[tex]f(x) = 3x^2 + 9[/tex]
[tex]f(g(x)) = 3(\frac{1}{3}x^2 - 9)^2 + 9[/tex]
[tex]f(g(x)) = 3(\frac{1}{3}x^2 - 9)(\frac{1}{3}x^2 - 9) + 9[/tex]
Expand Brackets
[tex]f(g(x)) = (x^2 - 27)(\frac{1}{3}x^2 - 9) + 9[/tex]
[tex]f(g(x)) = x^2(\frac{1}{3}x^2 - 9) - 27(\frac{1}{3}x^2 - 9) + 9[/tex]
[tex]f(g(x)) = \frac{1}{3}x^4 - 9x^2 - 9x^2 + 243 + 9[/tex]
[tex]f(g(x)) = \frac{1}{3}x^4 - 18x^2 + 252[/tex]
Calculating g(f(x))
[tex]g(x) = \dfrac{1}{3}x^2 - 9[/tex]
[tex]g(f(x)) = \frac{1}{3}(3x^2 + 9)^2 - 9[/tex]
[tex]g(f(x)) = \frac{1}{3}(3x^2 + 9)(3x^2 + 9) - 9[/tex]
[tex]g(f(x)) = (x^2 + 3)(3x^2 + 9) - 9[/tex]
Expand Brackets
[tex]g(f(x)) = x^2(3x^2 + 9) + 3(3x^2 + 9) - 9[/tex]
[tex]g(f(x)) = 3x^4 + 9x^2 + 9x^2 + 27 - 9[/tex]
[tex]g(f(x)) = 3x^4 + 18x^2 + 18[/tex]
Checking for inverse functions
[tex]f(x) = 3x^2 + 9[/tex]
Represent f(x) with y
[tex]y = 3x^2 + 9[/tex]
Swap positions of x and y
[tex]x = 3y^2 + 9[/tex]
Subtract 9 from both sides
[tex]x - 9 = 3y^2 + 9 - 9[/tex]
[tex]x - 9 = 3y^2[/tex]
[tex]3y^2 = x - 9[/tex]
Divide through by 3
[tex]\frac{3y^2}{3} = \frac{x}{3} - \frac{9}{3}[/tex]
[tex]y^2 = \frac{x}{3} - 3[/tex]
Take square root of both sides
[tex]\sqrt{y^2} = \sqrt{\frac{x}{3} - 3}[/tex]
[tex]y = \sqrt{\frac{x}{3} - 3}[/tex]
Represent y with g(x)
[tex]g(x) = \sqrt{\frac{x}{3} - 3}[/tex]
Note that the resulting value of g(x) is not the same as [tex]g(x) = \dfrac{1}{3}x^2 - 9[/tex]
Hence, f(x) and g(x) and not inverse functions

Let X - {V₁, V2,..., Un} be a subset of a vector space V over F. Let A(X) ... denote the set of linear combinations of the form a₁1 +0202 +. + anun, where a € F +0= 1. Prove that A(X) is a subspace of V if and only if v; Oy for a2 an vi and a₁ + a₂ + some i E {1,2,...,n}.
A(X) is a subspace of V if and only if v; Oy for a₂, a₃,..., an and a₁ + a₂ + ... + an = 1. This relationship highlights the connection between the subspace A(X) and the coefficients in the linear combinations of vectors in X.
Let X = {V₁, V₂,..., Vn} be a subset of a vector space V over F. The set A(X) is the set of all linear combinations of vectors in X, expressed as a₁V₁ + a₂V₂ + ... + anVn, where a₁, a₂,..., an ∈ F.
First, assume that A(X) is a subspace of V. This means A(X) satisfies the subspace criteria of closure under addition and scalar multiplication. For any vectors v and w in A(X) and any scalar c ∈ F, we have cv ∈ A(X) and v + w ∈ A(X). By expressing v and w as linear combinations of vectors in X, we can observe that the coefficients of the linear combinations can be added or multiplied by a scalar without violating the subspace criteria. Therefore, we can conclude that there exist coefficients a₁, a₂,..., an such that v = a₁V₁ + a₂V₂ + ... + anVn and w = a₁'V₁ + a₂'V₂ + ... + an'Vn, where a₁ + a₁' + ... + an + an' = 1.
Conversely, assume that v; Oy for a₂, a₃,..., an and a₁ + a₂ + ... + an = 1. We need to prove that A(X) satisfies the subspace criteria. For any vectors v and w in A(X) and any scalar c ∈ F, we can express v and w as linear combinations of vectors in X with coefficients a₁, a₂,..., an. By performing the operations of addition and scalar multiplication, we can see that the resulting linear combinations still satisfy the conditions v; Oy and a₁ + a₂ + ... + an = 1. Therefore, A(X) is closed under addition and scalar multiplication.

2) Pedro flips a fair coin 55 times and sees heads 21 times. What is the experimental probability that he will see heads? Put your answer as a percent.
Answer:
38.18%
Step-by-step explanation:
Experimental probability is probability that is determined on the basis of the results of repeated experiments.
Experimental Probability = The number of times a result happens / The number of times the experiment is carried out *100%
In this problem, The number of times a result happens is the number of times Pedro sees heads, which is 21. The number of time the experiment is carried out is 55.
So the result is 55/21 *100% = 38.181818... * 100%= 38.18%

You have now invested some money in your bank account with an interest rate of 5% every year. At year 3 , you will find out that you have $30,000 in your bank account. How much money will you have in your bank account at year 2?
a. $25,915.13
b. $27,210.88
c. $28,571.43
d. $30,000.00
e. None of the above
At year 2, you will have approximately $25,915.13 in your bank account, assuming an initial investment with a 5% interest rate compounded annually. The correct answer is (a).
To find out how much money you will have in your bank account at year 2, we can use the compound interest formula:
A = P(1 + r/n)^(nt)
Where:
A = Final amount (in this case, $30,000)
P = Principal amount (initial investment)
R = Annual interest rate (5% or 0.05)
N = Number of times interest is compounded per year (assumed to be once per year)
T = Number of years (in this case, 3)
Let’s solve for P, the principal amount at year 0:
30,000 = P(1 + 0.05/1)^(1*3)
30,000 = P(1.05)^3
Dividing both sides of the equation by (1.05)^3:
P = 30,000 / (1.05)^3
P ≈ 25,915.13
Therefore, at year 2, you will have approximately $25,915.13 in your bank account.
The correct answer is (a) $25,915.13.

find the radian measure of an angle at the center of a circle with radius 77.0 cm that intercepts an arc length of 128 cm
The radian measure of the angle at the center of the circle is approximately 1.6623 radians.
We are given that the radius of the circle is 77.0 cm and the length of the intercepted arc is 128 cm. We need to find the radian measure of the angle at the center of the circle.
To solve this problem, we use the formula relating the angle at the center of a circle, the radius of the circle, and the arc length intercepted by the angle.
The formula is given byθ = s/rwhereθ = angle at the center of the circle in radians s = arc length intercepted by the angle r = radius of the circle Substituting the given values, we getθ = 128/77.0 = 1.6623 radians (rounded to four decimal places)
Therefore, the radian measure of the angle at the center of the circle is approximately 1.6623 radians.

The total cost for a bucket of popcorn and 4 movie tickets is $56. The total cost for the same size bucket of popcorn and 6 movie tickets is $80. The cost of a bucket of popcorn is $8. Which equation represents the relationship between y, the total cost of the popcorn and movie tickets, and x, the number of movie tickets that are purchased?
y = 12x + 8
y = 12x − 8
y = 14x + 8
y = 14x − 8
Answer:
A
Step-by-step explanation:
y = 12x + 8
The correct equation represents the relationship between y, the total cost of the popcorn and movie tickets, and x, the number of movie tickets that are purchased is,
⇒ y = 12x + 8
Now,
Let p be the price of one bucket of popcorn and t be the price of one ticket.
Since, The total cost for a bucket of popcorn and 4 movie tickets is, $56
⇒ p + 4t = 56 .. (1)
And, the total cost for the same size bucket of popcorn and 6 movie tickets is $80.
⇒ p + 6t = 80 ..(2)
Now, Equation (1) - Equation (2),
-2 t = - 24
⇒ t = 12
By substituting this value in equation (1),
We get,
p + 48 = 56
⇒ p = 8
Thus, the price of one bucket of popcorn = $8
And, the price of one ticket = $12
Thus, The total price (y) of one bucket of popcorn and x tickets is,
y = 8 + 12 x
y = 12x + 8
