The length of the Hypotenuse is, [tex]\sqrt{5}x[/tex] units.

What is Pythagoras Theorem?

The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

Let the one leg of a right triangle is twice as long as the other.

Suppose the shorter leg is x.

So the longer leg is 2x.

Let, the hypotenuse is h.

By Pythagoras Theorem,

[tex]x^2 + (2x)^2 = h^2\\x^2 + 4x^2 = h^2\\5x^2 = h^2\\h = \sqrt{5} x[/tex]

Hence, the hypotenuse as a function of the length of the shorter leg, is [tex]\sqrt{5}x[/tex] units.

9 servings are there in 22.5 ounces of trail mix.

Given:

The weight of one serving of trail mix is 2. 5 ounces.

1 serving = 2.5 ounces

Number of servings = 22.5 ounces / 1 serving

= 22.5 / 2.5

= 225/10/25/10

= 225/25

= 9 servings.

Therefore 9 servings are there in 22.5 ounces of trail mix.

What is quadratic equation?

A quadratic equation in algebra is any equation that can be written in standard form as where x is an unknown and where a, b, and c denote known numbers, where a ≠ 0.

Let, for x^2 + mx + n = 0

⇒ x = 2α or 2β

From the given condition,

for x^2 + mx + n = 0 ⇒ x = α or x = β

Then,

2(α + β) = -m           ..(1)

4αβ = n                    ..(2)

and α + β = -p         ..(3)

αβ = m                     ..(4)

From equation (1) and (3),

-m/2 = -p

⇒ p = m/2

and from equation (2) and (4),

n/4 = m

⇒ n = 4m

Therefore,

n/p = 4m / (m/2) = 4 x 2 = 8

Hence, n/p = 8.

Five minutes into the descent the airplane has an altitude of 500 feet.

Given that an airplane at 3,000 feet begins to descend at a rate of

500 feet per minute, it is required to write an equation to model the situation and find the altitude of the airplane after 5 minutes.

First, we can model the situation through a linear equation of the form

y = mx + b.

Then, we must identify each variable:

y = A = Altitude

m = decrease per minute = 500

x = t = minute-time

b = Airplane height = 3,000

Now, we set up the equation, substituting y, m, x, and b into the linear equation, as the situation models the descent of the airplane the slope must be negative; thus:

A(t) = 3,000 − 500t

Lastly, we must find the altitude when if t = 5:

A(5) = 3,000 − 500(5)

Solving, we obtain:

A(5)=3,000 − 2,500 = 500

Hence the answer is, Five minutes into the descent the airplane has an altitude of 500 feet.

The smallest angles of the triangle is angle A

In triangle ABC

The length of the side AB = 6.2 units

The length of the side AC = 9.5 units

The length of the side BC = 5.1 units

The opposite angle of AB is angle C, the opposite angle of AC is angle B and the opposite angle of BC is angle A

We know length of the line is BC which is 5.1 units which is the smallest side of the triangle. Then the opposite angle of BC will be the smallest angle in the triangle ABC

The opposite angle of the side BC is angle A, which is the smallest angle in the triangle

Hence, the smallest angles of the triangle is angle A

This means that the per capita consumption of all poultry in 2015 was 95.16 pounds.

Here we have the linear function:

C(x) = 2.97*x+ 92.19

We know that it models the consumption of all poultry in a country as a function of x, the number of years since 2014.

Then C(1) will be the consumption of all poultry in that country one year after 2014 (this would be on 2015).

Probability that the arrow will stop on the same letter twice = 1/3 (c).

What is probability?

The area of arithmetic called likelihood deals with numerical representations of the chance that a happening can occur or that an announcement is true.

Main body:

Given : Maria will spin the arrow on the spinner 2 times.

To find : What is the probability that the arrow will stop on the same letter twice.

Solution : We have given a spinner that spin twice and stop on the same letter.

Formula for probability = no. of favourable outcome/ total outcomes

Here, total part of spinner = 3 and it spin two times

So, total possible outcome = 6.  Arrow stay on same letter twice( favorable outcome) =2.

Plugging the values in formula :

Probability =  2/6

Probability =  1/3

Therefore,  probability that the arrow will stop on the same letter twice =  (c).

The claim of invertible metrix is true and others are false.

In the given value we have to check which is true and which is false for the eigenvalues.

The eigenvalues are 2, 2, 5.

(1) First check the matrix is certainly invertible.

The matrix is invertible when the probuct of eigenvalues does not equal to zero.

invertible of A = 2*2*5

invertible of A = 20 which is not equal to zero.

So the matrix is certainly invertible. The claim is true.

(2) Now we check the matrix is certainly diagonalizable.

We note that the eigen value 2 has an algebraic multiplicity of 2 (number of repetitions), but we are unsure if the accompanying eigen vectors likewise have a count of two (geometric multiplicity)

The sum of the algebraic multiplicities must equal the sum of the geometric multiplicities in order for A to be diagonalizable.

In this instance, there is no evidence to support the geometric multiplicity of the eigenvalue 2. Therefore, we are unable to affirm that A is diagonalizable.

Consequently, the claim is false.

(3) Now we check the matrix is certainly not diagonalizable.

If the homogeneous equation from (A-⋋I)x=0 when the eigen value ⋋=2 is substituted x+y+z=0, then the solution set is x=-k-m where y=k, z=m are the parameters.

So it can be written as

[tex]\left[\begin{array}{ccc}x\\y\\z\end{array}\right] =k\left[\begin{array}{ccc}-1\\1\\0\end{array}\right] +m\left[\begin{array}{ccc}-1\\0\\1\end{array}\right][/tex]

Putting k=1 and m=1, then the corresponding eigen vectors for ⋋=2 are [tex]\left[\begin{array}{ccc}-1\\1\\0\end{array}\right],\left[\begin{array}{ccc}-1\\0\\1\end{array}\right][/tex]

So the geometric multiplicity of the eigen value ⋋=2 is 2.

The algebraic multiplicity = Geometric multiplicity we can see the given matrix A is diagonalizable.

So the statement is false.
