The Equation of the linear function is y = 2x + 1.

Here's a step-by-step explanation using the terms you've provided:

1. Identify the slope (m) and y-intercept (b): In a linear function, the equation is typically written in the form y = mx + b, where m represents the slope and b represents the y-intercept.

2. Find the slope: If you're given two points on the line (x1, y1) and (x2, y2), you can find the slope by using the formula: m = (y2 - y1) / (x2 - x1).

3. Determine the y-intercept: If you know the slope and one point on the line (x, y), you can find the y-intercept by rearranging the equation: b = y - mx.

4. Write the equation: Once you have the slope and y-intercept, you can write the equation in the form y = mx + b.

For example, suppose you are given two points on a line: (1, 3) and (3, 7). To write the equation of the linear function:

Step 1: Find the slope (m):
m = (7 - 3) / (3 - 1) = 4 / 2 = 2

Step 2: Determine the y-intercept (b) using one of the points, say (1, 3):
b = 3 - (2 * 1) = 1

Step 3: Write the equation:
y = 2x + 1

So, the equation of the linear function is y = 2x + 1.

Joe will reach the dam on June 6, which is 5 days after he starts his journey on June 1.

What is distance?

Distance is the measure of how far apart two objects or locations are from each other.

Let's first calculate the net distance Joe travels each day:

Net distance = Distance paddled upstream - Distance pushed downstream by the current

Net distance = 5 miles - 3 miles

Net distance = 2 miles

This means that Joe moves 2 miles closer to the dam each day.

To reach the dam, Joe needs to cover a distance of 10 miles upstream from his starting point. Since he covers 2 miles per day, he will take:

Days taken to reach the dam = Distance to cover ÷ Distance covered each day

Days taken to reach the dam = 10 miles ÷ 2 miles per day

Days taken to reach the dam = 5 days

Therefore, Joe will reach the dam on June 6, which is 5 days after he starts his journey on June 1.

Answer:

2 bus

Step-by-step explanation:

The expected value of y is larger than the expected value of x. This is because y takes into account the number of students on all 4 buses, while x only takes into account the students on the bus with the randomly selected student.

The expected value of a random variable represents the average value of that variable over multiple trials. In this case, x is a random variable representing the number of students on the bus carrying the randomly selected student, and y is a random variable representing the number of students on the randomly selected bus.

The expected value of x can be calculated as follows:

E[x] = (10/100)×10 + (20/100)×20 + (30/100)×30 + (40/100)×40

= 16 + 12 + 9 + 16

= 53/4

= 13.25

This means that, on average, the bus carrying the randomly selected student would have 13.25 students.

The expected value of y can be calculated as follows:

E[y] = (1/4)×10 + (1/4)×20 + (1/4)×30 + (1/4)×40

= 25

This means that, on average, the randomly selected bus would have 25 students.

As expected, the expected value of y is larger than the expected value of x. This is because y takes into account the number of students on all 4 buses, while x only takes into account the students on the bus with the randomly selected student. Since the number of students on the other 3 buses can vary widely, y has a higher expected value than x.

What is polynomial function?

A polynomial function is a mathematical function that consists of a sum of terms, where each term is a constant multiplied by one or more variables raised to a non-negative integer power.

When we arrange a polynomial in descending order of powers of one of its variables, it means we are writing the terms with the highest power first, followed by terms with the next highest power, and so on until we reach the constant term (which has no variable).

In this case, the polynomial is [tex]7x^3y^3-3xy^5+2x^2y^4-x^4y^2[/tex]. To write this in descending order of powers of x, we need to start with the term that has the highest power of x, which is [tex]-x^4y^2[/tex].

Then we write the term with the next highest power of x, which is [tex]7x^3y^3[/tex]. After that, we write the term with the next highest power of x, which is [tex]2x^2y^4[/tex]. Finally, we write the term with the lowest power of x, which is [tex]-3xy^5[/tex].

So the correct order of the polynomial in descending powers of x is option A: [tex]-x^4y^2+7x^3y^3+2x^2y^4-3xy^5[/tex].

According to the question the measure of angle 3, or m∠3, is also 19 degrees since angle 2 and angle 3 are vertical angles. So: m∠3 = m∠23 = 19°

We know that vertical angles are congruent, so if angle 21 and angle 22 are vertical angles, then:

m∠21 = m∠22

We also know that angle 22 and angle 23 are complementary angles, which means:

m∠22 + m∠23 = 90°

Substituting m∠22 with m∠21, we get:

m∠21 + m∠23 = 90°

We are given that m∠21 = 71 degrees, so we can substitute that in the equation:

71° + m∠23 = 90°

Subtracting 71° from both sides, we get:

m∠23 = 19°

Therefore, the measure of angle 3, or m∠3, is also 19 degrees since angle 2 and angle 3 are vertical angles. So:

m∠3 = m∠23 = 19°

If integers a, b, c, and d, not necessarily distinct, are chosen independently and at random from 0 to 2007, the probability that ad-bc is even is 10/16.

To solve the problem, we need to consider the parity of the product ad and bc separately. If both ad and bc are even, then their difference (ad-bc) is even. If both ad and bc are odd, then their difference is even as well. However, if one of ad and bc is odd and the other is even, then their difference is odd.

For ad to be even, either a or d (or both) must be even. Similarly, for bc to be even, either b or c (or both) must be even. Therefore, the probability that ad and bc are both even is the product of the probabilities that a, b, c, and d are even:

P(ad even) = P(a even)P(d even) = (1004/2008)^2 = 1/4

P(bc even) = P(b even)P(c even) = (1004/2008)^2 = 1/4

The probability that ad-bc is even is the sum of the probabilities that both ad and bc are even and that both ad and bc are odd:

P(ad-bc even) = P(ad even and bc even) + P(ad odd and bc odd)

= P(ad even)P(bc even) + P(ad odd)P(bc odd)

The calculatd value of the length of side WX is 1.25 cm.

Let's call the length of side WX "x".

The mid-segment of a trapezoid is the line segment connecting the midpoints of the non-parallel sides.

The length of the mid-segment is equal to the average of the lengths of the two parallel sides. In this case, the mid-segment is 2.75 cm long and connects the midpoints of sides WZ and XY.

We can use the formula for the length of the mid-segment of a trapezoid:

mid-segment length = (length of side WZ + length of side XY) / 2

Plugging in the values we know, we get:

2.75 = (x + 4.25) / 2

Multiplying both sides by 2, we get:

5.5 = x + 4.25

From the question, we have the following parameters that can be used in our computation:

y = 6x^3

To find the derivative of y with respect to x, we can use the power rule of differentiation, which states that the derivative of x^n with respect to x is n*x^(n-1).

Using this rule, we can differentiate y = 6x^3 as follows:

dy/dx = d/dx (6x^3)

= 6 * d/dx (x^3)

Having factorized using identities, the result is [(a^2c + b^2a + c^2b)/(abc)][(a^2 + b^2 + c^2 - a^2b^2c^2)/(a^2b^2c^2)]

One possible approach to factorizing the expression is to use the identity:

a^3 + b^3 + c^3 - 3abc = (a + b + c)(a^2 + b^2 + c^2 - ab - ac - bc)

If we let a = b/c, b = c/a, and c = a/b, then we can substitute these expressions into the identity and simplify:

(a/b)^3 + (b/c)^3 + (c/a)^3 - 3abc/a^3b^3c^3

= [(a/b) + (b/c) + (c/a)][(a/b)^2 + (b/c)^2 + (c/a)^2 - (a/b)(b/c) - (a/b)(c/a) - (b/c)(c/a)]

Volume of the sphere = 944cm^3

Let us consider V be the volume of the sphere.

And r be the radius of the sphere.

The formula for the volume of a sphere is,

V = (4/3) × π × r^3

Solve for the radius of the sphere by rearranging the formula as follows,

⇒ r^3 = (3/4) × (V/π)

⇒r = [(3/4)×(V/π)]^(1/3)

Substituting V = 944 cm^3, we have,

⇒ r = [(3/4) ⇒ (944/π)]^(1/3)

⇒r ≈ 6.08 cm

⇒r ≈ 6.1 cm (rounded to one decimal place)

The diameter of the sphere is twice the radius, so the diameter is,

d = 2r

Let's use "w" to represent the width of the rectangle and "l" to represent the length.

According to the problem statement, the area of the rectangle is numerically equal to its perimeter, so we can write:

2(l + w) = lw

Simplifying this equation, we get:

2l + 2w = lw

Dividing both sides by 2, we get:

l + w = 0.5lw

Multiplying both sides by 2, we get:

2l + 2w = lw

Since the length of the rectangle is 5 times its width, we can write:

l = 5w

Substituting this into the previous equation, we get:

2(5w) + 2w = 5w^2

Simplifying this equation, we get:

10w + 2w = 5w^2

12w = 5w^2

Dividing both sides by w, we get:

12 = 5w

So the width of the rectangle is:

w = 12/5 = 2.4 cm

And the length of the rectangle is:

l = 5w = 12 cm

Therefore, the width of the rectangle is 2.4 cm and the length of the rectangle is 12 cm.

Answer:

Width: 2.4 cm

Length: 12 cm

Step-by-step explanation:

Let the width of the rectangle be w cm, and the length be 5w cm. The area A and perimeter P of the rectangle can be expressed as follows:

Area (A) = length × width

A = 5w × w = 5w^2 cm^2

Perimeter (P) = 2 × (length + width)

P = 2 × (5w + w) = 2 × 6w = 12w cm

According to the problem, the area is numerically equal to the perimeter:

A = P

5w^2 = 12w

To solve for w, we can rearrange the equation:

5w^2 - 12w = 0

w(5w - 12) = 0

This equation has two possible solutions:

w = 0

In this case, the width would be 0 cm, which doesn't form a valid rectangle.

5w - 12 = 0

5w = 12

w = 12/5 = 2.4 cm

For the second solution, the width is 2.4 cm. Now, we can calculate the length:

length = 5w

length = 5 × 2.4 = 12 cm

So, the width of the rectangle is 2.4 cm, and the length is 12 cm.
