The equation given by Jill and Joel both are correct. Option C .

The line passing through the points (2, -1) and (-1, 14).

The equation of a line passing through a point \((x_1, y_1)\) is \(y-y_1=m (x-x_1)\) where m is the slope.

To find the slope m, using slope formula.

\(m=\frac{y_2-y_1}{x_2-x_1} \\m=\frac{14-(-1)}{-1-3} \\m=-5\)

Further simplify,

Substitute the values in the given formula.

\(y-y_1=m(x-x_1)\\y-(-1)=-5(x-2)\\y+1=-5(x-2)\)

Further simplify,

5x+y=9

Both the equations are correct.

For two independent random variable - x and y, where the mean and standard deviation of x is 2.5in and 0.6in respectively and of y is 2.25in and 0.4in respectively, the mean and standard deviation of d, x-y is 0.25in and 0.72in respectively.

Therefore the answer is 0.25in and 0.72in.

The mean of x is 2.5in and standard deviation of x is 0.6in.

μ1 = 2.5

σ1 = 0.6

Variance of x can be obtained by

σ1² = 0.6² = 0.36

The mean of y is 2.25in and standard deviation of y is 0.4in.

μ2 = 2.25

σ2 = 0.4

Variance of y can be obtained by

σ2² = 0.4² = 0.16

Variance of the difference of the independent random variables, d = x - y can be obtained by

σ12² = σ1² + σ2²

= 0.36 + 0.16

= 0.52

The standard deviation of the difference can be obtained by

σ12 = √0.52

= 0.72

Mean of the difference, d can be obtained by

The vector P × Q points in the direction [20/7, 11/7, 5]. One possible vector that is orthogonal to [4, -5, 7] is [1, 0, -4/7].

To determine a vector that is orthogonal (perpendicular) to [4, -5, 7], we can find a vector that has a dot product of zero with [4, -5, 7].

Let's denote the vector we are looking for as [x, y, z]. To ensure orthogonality, we can set up the dot product equation:

[4, -5, 7] · [x, y, z] = 0

Taking the dot product of the two vectors, we have:

4x - 5y + 7z = 0

This equation represents a plane in three-dimensional space. To find a vector that lies on this plane and is orthogonal to [4, -5, 7], we can choose arbitrary values for two of the variables (x, y, or z) and solve for the third variable.

Let's set x = 1 and y = 0:

4(1) - 5(0) + 7z = 0

4 + 7z = 0

7z = -4

z = -4/7

Therefore, one possible vector that is orthogonal to [4, -5, 7] is [1, 0, -4/7].

Now let's consider the direction of the cross product between [4, -5, 7] and [1, 0, -4/7], denoted as P × Q.

To find the cross product, we can use the formula:

P × Q = [P2Q3 - P3Q2, P3Q1 - P1Q3, P1Q2 - P2Q1]

Substituting the given values, we have:

[4, -5, 7] × [1, 0, -4/7] = [(−5)(−4/7) − 7(0), 7(1) − 4(−4/7), 4(0) − (−5)(1)]

= [20/7, 11/7, 5]

Therefore, the vector P × Q points in the direction [20/7, 11/7, 5].

Answer:

f(3)=-4; x=1

Step-by-step explanation:

Just use the graph

\(\huge\boxed{f(3)=-4}\\\huge\boxed{f(1\ \textsf{or}\ 4)=2}\)

For this question, we just need to look at the graph.

\(f(3)=\ ?\)

Go to \(3\) on the x-axis and see what value from the y-axis it intersects with.

It's \(-4\), right at the bottom of the little valley there.

\(f(?)=2\)

For this part, we do the opposite. Go to \(2\) on the y-axis and find one value it intersects with from the x-axis.

You can go with either \(1\) or \(4\) here.

C. The two quantities are equal.  We can see that both Quantity A and Quantity B have the same value of 1. Hence, the two quantities are equal.

Since we know that the length of each side of triangle T is 6 times the length of each side of triangle X, we can set up the following equations:
Length of side of T = 6 * Length of side of X
To compare the ratios of the sides, we can use the following formula:
Ratio of one side to another = Length of one side / Length of another side
For Quantity A, we can choose any two sides of triangle T and find their ratio. Let's choose the two adjacent sides:

To further explain the concept, let's consider the properties of equilateral triangles.
An equilateral triangle is a special type of triangle where all three sides are equal in length. Hence, if we know the length of one side, we automatically know the length of all three sides.
Now, coming back to the given question, we are told that the length of each side of triangle T is 6 times the length of each side of triangle X. This means that if the length of one side of triangle X is 'a', then the length of one side of triangle T is 6 times 'a', which is '6a'.
Hence, we can write:
Length of side of T = 6a
Length of side of X = a
Now, let's compare the ratios of the sides.
For Quantity A, we need to find the ratio of one side of triangle T to another side of T. Let's choose the two adjacent sides:
Ratio of adjacent sides of T = Length of side of T / Length of adjacent side of T
Since all three sides of an equilateral triangle are equal, the adjacent side of T is also 6a. Hence, we get:
Ratio of adjacent sides of T = (6a) / (6a) = 1
For Quantity B, we need to find the ratio of one side of triangle X to another side of X. Let's again choose the two adjacent sides:
Ratio of adjacent sides of X = Length of side of X / Length of adjacent side of X
Since all three sides of an equilateral triangle are equal, the adjacent side of X is also 'a'.

Connective tissue bands called annular ligaments prevent flexor tendons of the forearm and leg from rising like bowstrings.

Annular ligaments are ring-like structures made of fibrous tissue that surround and hold tendons in place as they pass through tight spaces in the body. In the forearm, the annular ligaments hold the tendons of the flexor muscles in place as they pass under the wrist and into the hand.

In the leg, the annular ligaments hold the tendons of the hamstring muscles in place as they pass behind the knee.

Without annular ligaments, the tendons would be able to move too freely, causing them to bowstring and reducing their effectiveness in controlling movement. The annular ligaments help to keep the tendons in the correct position, allowing them to function properly and enabling smooth and efficient movement of the joints.

Step-by-step explanation:

If the new number is four times the reciprocal of the original number, then  the original number is 0.02.

Let us assume the original positive decimal number is = "x".

When we move the decimal point of x four places to the right,

We get,  "10000x", which is four times the reciprocal of x.

So, equation can be written as;

⇒ 10000x = 4(1/x),

On simplifying the equation,

We get,

⇒ 10000x² = 4,

Dividing both sides by 10000,

We get,

⇒ x² = 0.0004,

Simplifying further,

We get,

⇒ x = 0.02

Therefore, the original positive decimal number is 0.02.

Answer: I don't know, sorry!

Step-by-step explanation:

The assertion that which shows that P(k + 1) is true provided Pk in the Inductive step is true. Moreover, P(1) is also true. Hence, by induction principle, we can say that P(n) is true for all positive integer n.

What is Integer?

A zero, a positive natural number, or a negative integer with a minus sign is an integer. The negative numbers are the additive inverses of their positive counterparts.

Given that P(n) be the assertion

∑j² = n (n+1)(2n+1)/6

(a) For n = 3, we get

∑j² = 1² + 2²+3² =14

= 3(3+1)(6+1)/6

=14

Hence, P(3) is true.

(b) Expression for P(k) may take the form

∑j² = k (k+1)(2k+1)/6

(c) Expression for P(k + 1) may take the form

∑j² = (k+1) (k+2)(2k+3)/6

(d)Base case:

In base case, we must prove that P(1) is true.

(e) To prove P(n) will be true for every positive integer n, we need to prove that P(k + 1) is true in the inductive step, where k is a positive integer.

(f) In the Inductive step, the Inductive hypothesis is that Pk is true for positive integer k.

(g)Base case:

a) For n=1, we get

RHS= 1(1+1)(2+1)/6

=1

Hence, P(1) is true.

Inductive hypothesis:

Assume P(k) is true:

∑j² = k (k+1)(2k+1)/6

Inductive step:

Now,

∑j² = k (k+1)(2k+1)/6 +(K+1)²

which shows that P(k + 1) is true provided P(k) in the Inductive step is true. Moreover, P(1) is also true. Hence, by induction principle, we can say that P(n) is true for all positive integer n.

Length of Line BE = √40 units  

The length of a line segment is nothing but the shortest distance between two endpoints of the line segment. If we know the endpoints of a line segment,  We can determine the length of the line segment using the distance formula. The formula for distance is given below  

Where, (x₁, y₁) and (x₂, y₂) are end points of line segment

Here we have

A graph in which b and e are located

From the graph, we can take b (7, 6) and e (5, 0)

And the length of BE = distance between b and e

As we know the formula for the distance between 2 points is given

Distance = √(y₂- y₁)² + (x₂ - x₁)²

Length of BE = √(0 - 6)² + (5 - 7)²  

= √(- 6)² + (- 2)² = √36 + 4  = √40
