So the equation of the line in slope-intercept form is y = x + 2. The y-intercept is 2.

What is linear equation ?

Linear equation can be defined as equation in which highest degree is one.

In this problem, you are given a graph of a linear function. The graph shows two points on the line: (-2, 0) and (3, 5).

To find the slope of the line, we can use the formula:

slope = (change in y) / (change in x)

We can use the two points given to find the change in y and the change in x:

change in y = 5 - 0 = 5

change in x = 3 - (-2) = 5

Plugging these values into the formula, we get:

slope = 5/5 = 1

So the slope of the line is 1.

To find the y-intercept of the line, we can use one of the points on the line and the slope we just found. Let's use the point (-2, 0):

y - y1 = m(x - x1)

where (x1, y1) is the point (-2, 0) and m is the slope we just found:

y - 0 = 1(x - (-2))

y = x + 2

Therefore, the equation of the line in slope-intercept form is y = x + 2. The y-intercept is 2.

The solutions to the equation are x=1.25 and x=0.5. These are the values of w that make the equation true.

To solve the quadratic equation [tex]8w^(2)-14w+5=0[/tex] using the quadratic formula, we first need to identify the values of a, b, and c. In this case, a=8, b=-14, and c=5. The quadratic formula is:

[tex]x = (-b ± √(b^(2)-4ac))/(2a)[/tex]

Plugging in the values of a, b, and c, we get:

[tex]x = (-(-14) ± √((-14)^(2)-4(8)(5)))/(2(8))[/tex]

Simplifying the equation, we get:

x = (14 ± √(196-160))/16

x = (14 ± √36)/16

x = (14 ± 6)/16

Now we can solve for the two possible values of x:

x = (14+6)/16 = 20/16 = 1.25

x = (14-6)/16 = 8/16 = 0.5

As per the unitary method, the bakery sold 2294 coffee buns.

Let us assume that the number of blueberry buns sold by the bakery is x. According to the problem, the number of coffee buns sold is 1560 more than the number of blueberry buns sold. Therefore, the number of coffee buns sold can be expressed as (x + 1560).

Now, we are given that the total number of buns sold (both coffee and blueberry) is 3028. Therefore, we can set up an equation based on the given information:

x + (x + 1560) = 3028

Simplifying this equation, we get:

2x + 1560 = 3028

2x = 1468

x = 734

Therefore, the number of blueberry buns sold by the bakery is 734. Now, we can use the unitary method to find the number of coffee buns sold. We know that the number of coffee buns sold is 1560 more than the number of blueberry buns sold, which is:

x + 1560 = 734 + 1560 = 2294

The equation of the sine function is: y = 4 sin(1/4 x).

What is a sine function?

A sine function is a type of trigonometric function that relates the angle of a right triangle to the ratio of the length of its opposite side to its hypotenuse. It is defined as the ratio of the length of the opposite side of an angle in a right triangle to the length of the hypotenuse.

The general form of a sine function is:

y = A sin(Bx + C) + D

where A is the amplitude, B determines the period (B = 2π/period), C is the phase shift, and D is the vertical shift.

Substituting the given values, we get:

A = 4 (amplitude)

Period = 8π

B = 2π/Period = 2π/(8π) = 1/4

C = 0 (no phase shift)

D = 0 (no vertical shift)

the equation of the sine function is:

y = 4 sin(1/4 x)

Note that the value of B is the reciprocal of the period, since the formula for period is T = 2π/B, which can be rearranged to get B = 2π/T.

Hence, the equation of the sine function is: y = 4 sin(1/4 x).

To convert grams to pounds, we need to first convert grams to kilograms, and then kilograms to pounds.

Given that 1 gram = 0.001 kilograms, we can convert 23,000 grams to kilograms as follows:

23,000 grams = 23,000 * 0.001 kilograms = 23 kilograms

Now, given that 1 kilogram ≈ 2.2 pounds, we can convert 23 kilograms to pounds as follows:

23 kilograms * 2.2 pounds/kilogram = 50.6 pounds

Therefore, 23,000 grams is equivalent to 50.6 pounds.

Answer:

Part A: To create an expression to represent the amount of canned food collected so far by the three friends, we need to add up their individual contributions. Therefore, the expression would be:

Amount collected = (3x² - 2) + (x²) + (2xy + 5)

Amount collected = 4x² + 2xy + 3

Part B: To find the expression that represents the number of cans the friends still need to collect to meet their goal, we need to subtract the amount collected from their goal expression. Therefore, the expression would be:

Cans still needed = 6x² - 2xy + 8 - (4x² + 2xy + 3)

Cans still needed = 2x² + 5

The difference quotient [f(x+h)-f(x)]/h for the function f(x)=-5x-1 is -5.

To find and simplify the difference quotient [f(x+h)-f(x)]/h for the function f(x)=-5x-1, we need to substitute (x+h) into the function for x and then simplify.

First, let's substitute (x+h) into the function for x:
f(x+h) = -5(x+h) - 1

Next, let's simplify:
f(x+h) = -5x - 5h - 1

Now, let's subtract f(x) from f(x+h):
[f(x+h) - f(x)] = (-5x - 5h - 1) - (-5x - 1)

Simplifying further:
[f(x+h) - f(x)] = -5h

Finally, let's divide by h:
[f(x+h) - f(x)]/h = -5h/h = -5

Therefore, the difference quotient [f(x+h)-f(x)]/h for the function f(x)=-5x-1 is -5.

Correct statement: Two vectors are perpendicular if and only if the dot product of the two vectors is zero.

Explanation:

Two vectors are perpendicular if and only if the dot product of the two vectors is zero. This is equivalent to saying that the angle between the two vectors is 90 degrees. Therefore, the statement "Two vectors are perpendicular if and only if the angle between them is 90 degrees" is correct.

Every orthonormal set is linearly independent. This statement is also correct. An orthonormal set of vectors is a set of vectors that are pairwise perpendicular and have length 1.

Since the dot product of any two distinct vectors in an orthonormal set is 0, it follows that any linear combination of these vectors will also have a dot product of 0 with any other vector in the set.

Therefore, the only solution to a linear combination of these vectors being equal to the zero vector is for all the coefficients to be 0, which implies linear independence.

Every orthogonal set is linearly independent. This statement is also correct. An orthogonal set of vectors is a set of vectors that are pairwise perpendicular, but not necessarily of length 1.

Similar to the previous argument, the dot product of any two distinct vectors in an orthogonal set is 0, which implies linear independence.

R^n has an orthonormal basis. This statement is also correct. An orthonormal basis for a vector space is a basis consisting of orthonormal vectors. It can be shown that any finite-dimensional inner product space has an orthonormal basis, and R^n is a finite-dimensional inner product space with the standard dot product.

The zero vector is perpendicular to all other vectors. This statement is false. The zero vector is orthogonal to all other vectors, but not necessarily perpendicular, as the concept of perpendicularity requires the vectors to have a nonzero length.

Any orthonormal set in R^n is a basis. This statement is also correct. An orthonormal set of n vectors in R^n must span the entire space, as any vector in the space can be expressed as a linear combination of these vectors.

Furthermore, any set of n linearly independent vectors in R^n is a basis, so the fact that an orthonormal set is linearly independent (as shown in statement 2) implies that it is a basis.

The measures of those two angles are, 20° and 110°

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

Two angles of a quadrilateral measure 180° and 50°.

And, The other two angles are in a ratio of 2:11.

Since, The other two angles are in a ratio of 2:11.

Hence, ,Measures of both angles are, 2x and 11x.

Now, We know that;

Sum of all interior angles of a quadrilateral are 360°.

Hence, We get;

⇒ 180 + 50 + 2x + 11x = 360

⇒ 230 + 13x = 360

⇒ 13x = 360 - 230

⇒ 13x = 130

⇒ x = 10

Thus, Measures of both angles are,

2x = 2 × 10 = 20°

and 11x = 11 × 10 = 110°

The value of n in the n-sided polygon, with sides AC and AD, where the external angle formed at the point the decagon touches the n-sided polygon is 60° is; n = 15

A polygon is a planar shape with three or more straight sides.

The sum of angles at a point property indicates that, the sum of angles at the point A can be presented as follows;

∠BAC + ∠CAD + ∠DAB = 360°

Angle ∠BAC = 60°

Angle ∠DAB is an interior angle of a 10-sided regular polygon, (a decagon),  therefore, the measure of angle ∠DAB is 144°

Plugging in the values of the measures of the angles ∠BAC and ∠DAB, in the equation, ∠BAC + ∠CAD + ∠DAB = 360°, we get;

+ ∠CAD + 144° = 360°

∠CAD = 360° - (144° + 60°) = 156°

∠CAD = 156°

The formula for finding the measure of the interior angle of an n-sided polygon, θ, can be presented as follows;

θ = (n - 2) × 180°/n

Where the interior angle, θ = 156°, which is the measure of ∠CAD, in the n-sided polygon, we get;

156° = (n - 2) × 180°/n

156·n = 180·n - 360

360 = 180·n - 156·n = 24·n

n = 360/24 = 15

The work performed on the steam in this compression process per kilogram is -50 kPa*V/kg.\

To find the work performed on the steam in this compression process per kilogram, we need to use the following formula:

W = PΔV

Where W is the work, P is the pressure, and ΔV is the change in volume.Since the process is isothermal, the pressure and volume are inversely proportional.

This means that if the pressure is doubled, the volume will be halved. In this case, the pressure is constant at 100 kPa, and the volume is halved because half of the vapour has condensed.

Therefore, the change in volume is:

ΔV = V/2 - V = -V/2

Substituting this into the formula for work, we get:

W = PΔV = (100 kPa)(-V/2) = -50 kPa*V

To find the work per kilogram, we need to divide the work by the mass of the steam. Since the mass is not given in the question, we can assume it is 1 kilogram. Therefore, the work per kilogram is:

-50 kPa*V/1 kg = -50 kPa*V/kg

This shows how far apart the two balls are at time t. The two terms can be interpreted as follows: The initial separation between the two balls at time t=0 is represented by the constant term, h0 (in fact, the first ball is still at the top of the building, while the second ball is on the ground). For this issue[tex]h_{0} =30 feet.[/tex] The second ball's initial velocity, which serves as the coefficient of the linear term, [tex]u_{y}[/tex]tells us that the gap between the two balls closes by [tex]u_{y}[/tex] feet every second.

To find the p-value, we need to use the standard normal table or a calculator with a normal distribution function. The p-value is the probability of observing a test statistic as extreme or more extreme than the one observed, given that the null hypothesis is true.

In this case, we are looking for the probability that z is greater than or equal to 1.12, given that the null hypothesis is true.

Using a standard normal table, we can find the area to the left of z=1.12, which is 0.8686. However, we are interested in the area to the right of z=1.12, which is 1 - 0.8686 = 0.1314.

This is the p-value for a one-tailed test. However, the hypothesis test in the question is a two-tailed test, so we need to double the p-value to get the final answer. The p-value for a two-tailed test is 2 * 0.1314 = 0.2628.

The fourth point has coordinates (-17, 0).

The x-coordinate of A remains constant but the sign of the y-coordinate changes if A is mirrored over the x-axis to form A'. Hence, if Has a coordinates (a, b), A' must also have coordinates (a, -b).

Given that A and A' are the corners of a rectangle that are opposite one another, the other two corners of the rectangle must be on a horizontal line that passes through A and A"s midpoint (a, 0). Since (a, 0) and the fourth point (let's call it C) are separated by 2|b|, the distance between A and A' is also 2|b|. This indicates that depending on which side of the line AA' C is on, it has coordinates of (a + 2|b|, 0) or (a - 2|b|, 0).

In this instance, the coordinates of A are (3, 5) and those of A' are (3, -5). The intersection of A and A' is (3, 0). A and A' are separated by 2|5|, which equals 10.

The fourth point, C, thus, has coordinates of either (3 + 2(10), 0) = (23, 0) or (3 - 2(10), 0) = (-17, 0).

The right response is (3 - 2(10), 0), which can be deduced from the graph since the rectangle is symmetric about the y-axis (-17, 0).
