The equation which is the best model for a line of best fit for the data is y = ½ x – 1. (Option B)

A line of best fit refers to a straight line which minimizes the distance between it and some data. It expresses a relationship in a scatter plot of different data points. It is an educated guess about where a linear equation which may fall in a set of data plotted on a scatter plot. It is an output of regression analysis and is used as a prediction tool.

The equation of the line can be determined using slope intercept form of the line which is y = mx + b where m is the slope and b is the y intercept. From the given graph, two points which lie on the line of best fit can be used to determine the slope. Let consider two points (2, 0) and (0, -1). Hence

m = (-1 – 0)/(0 – 2) = -1/-2 = ½

The value of y intercept is -1 (when x = 0)

Hence, the equation is:

y = ½ x - 1

The average speed of the car while taking photos in m/s is 1.6 m/s

Total photos taken = 2

Time taken = 0.5 seconds

Distance = 0.8m

Thus, this can be noted as -

Distance = Marks on the road between the two photos = 0.8 meters

Time = Time between the two photos = 0.5 seconds

Speed is defined as the rate at which a distance travelled or a height reached changes. It has a time component. In the given case, the speed camera is taking photos and we are required to calculate the average speed of the car

Calculating the speed -

Average Speed = Distance ÷ Time

Step-by-step explanation:

Step 1:  Find slope of Linear function A

\(slope = \frac{y_2 - y_1}{x_2-x_1} = \frac{-5--1}{-4--2} = \frac{-5 +1}{-4+2} = \frac{-4}{-2} = 2\)

Step 2 : Find slope of B

Since they are perpendicular to each other, product of their slope = -1

That is,

   \(m_A \times m_B = - 1\\2 \times m_B = -1\\\\slope, m_B = \frac{-1}{2}\)

Given the function passes through (4, -6)

Equation of the linear function :

                                         \(x_3 = 4 \ , \ y_3 = -6\\\\(y - y_3) = m_B (x - x_3)\\\\(y - -6) = -\frac{1}{2} (x - 4)\\\\y + 6 = -\frac{1}{2}x + 2\\\\y = -\frac{1}{2}x + 2 - 6 \\\\y = -\frac{1}{2}x -4\)

Part B

Linear Function is parallel to B

Therefore the slope of B and slope of C are the same. And the equation will be of the form :

The equation of the function is −3<x<1. See the explanation below.

Given the graph of function f is a parabola,

Thus, equation of parabola  is y=(x+3)(x+1)

⇒y=x² +4x+3

⇒y−3+2²

= x²+2× x ×2+2²

⇒y+1=(x+2)²

We can rewrite this as

 (x+2)² =4× (1/4) ×(y+1)

Comparing the above equation to the equation of a parabola, (x−h)² =4a(y−k), where (h,k) is the coordinates of vertex of parabola, we have,

(h,k)≡(−2,−1)

Answer:

r = 50000

P (r) = 0.7r - 35000

Step-by-step explanation:

Given cost function is

C (r) = 0.85r + 35000

and revenue function is

R (r) = 1.55r

At break even point, revenue is equal to cost

R(x)= C(x)

1.55r = 0.85r+35000

Subtract 0.85 from both sides

0.7r = 35000

divide by 0.7 on both sides

r = 50000

Profit function

P(x)= R(x)- C(x)

P(r) = 1.55r - (0.85r+35000)

P(r) = 1.55r - 0.85r - 35000

P(r) = 0.7r - 35000

Answer:

The angle measures 71.6 degrees, and its complementary angle measures 18.4 degrees

Step-by-step explanation:

Let x be the measure of the angle, and y be the measure of its complementary angle.

We know that the sum of the measures of complementary angles is 90 degrees:

x + y = 90

We are also given that the angle x is 53.2 degrees more than its complementary angle y:

x = y + 53.2

Now we can substitute the second equation into the first equation to solve for y:

y + 53.2 + y = 90

2y + 53.2 = 90

2y = 36.8

y = 18.4

So the measure of the complementary angle is 18.4 degrees.

We can now use the second equation to find the measure of the angle x:

x = y + 53.2 = 18.4 + 53.2 = 71.6

So the measure of the angle is 71.6 degrees.

Therefore, the measures of the angle and its complementary angle are 71.6 degrees and 18.4 degrees, respectively.

The maximum number of people who can stand in each side of the boat is equal to the buoyant force divided by the average mass of a person multiplied by the acceleration due to gravity.

The maximum number of people who can stand in each side of a boat can be determined using Archimedes' Principle. This principle states that the buoyant force on an object is equal to the weight of the fluid it displaces. In the case of a boat, the buoyant force is equal to the weight of the water it displaces.

Using this principle, the maximum number of people who can stand in each side of a boat can be calculated using the equation:

F_B = m_p * g

Where F_B is the buoyant force, m_p is the total mass of all the people standing in the boat, and g is the acceleration due to gravity.

To determine the maximum number of people, we must first calculate the mass of the boat, m_b. We can do this by multiplying the volume of the boat (V) by the density of the material the boat is made of (ρ).

m_b = V * ρ

Next, we can calculate the total mass of all the people standing in the boat, m_p. This can be calculated by multiplying the total number of people (n) by the average mass of a person (m).

m_p = n * m

Finally, we can calculate the maximum number of people who can stand in each side of the boat by rearranging the equation for F_B and solving for n.

n = (F_B) / (m * g)

Therefore, the maximum number of people who can stand in each side of the boat is equal to the buoyant force divided by the average mass of a person multiplied by the acceleration due to gravity.

The total electric potential at point a is the sum of the electric potentials due to q1 and q2 is 0, the total electric potential at point b is the sum of the electric potentials due to q1 and q2 is 84.5 and the work done on q3 by the electric forces exerted by q1 and q2 is -0.42 J.

The electric potential at point a due to q1 and q2 can be calculated using the formula for electric potential due to a point charge,

V=kq/r, where k=9×10^9 N.

m²/C² is the Coulomb constant,

q is the point charge,

and r is the distance from the point charge to the point where the potential is being measured.

Using this formula, the electric potential due to q1 at point a is:

V1=kq1/r1

where q1=+2.00μC is the charge on q1 and r1 is the distance from q1 to point a.

Since q1 is at one of the corners of the square and a is at the center, the distance r1 is half the length of the diagonal of the square:

r1=√(12+12)=0.75 cm

Substituting the values in the formula, we get:

V1 = 9×10^9×2.00×10^-6/0.75×10^-2V1

     = 240 V

The electric potential due to q2 at point a can be calculated similarly.

Since q2 is at the opposite corner of the square, the distance r2 is the length of a side of the square:

r2=1.50 cm

Substituting the values in the formula, we get:

V2 = 9×10^9×(-2.00)×10^-6/1.50×10^-2V2

     = -240 V

The total electric potential at point a is the sum of the electric potentials due to q1 and q2:

V = V1+V2V=240 - 240V

   = 0

Since point b is at the empty corner closest to q2, the electric potential at point b due to q2 is zero.

The electric potential at point b due to q1 can be calculated using the same formula we used for point a:

V1=kq1/r1

where q1=+2.00μC is the charge on q1 and r1 is the distance from q1 to point b.

Since q1 is at one of the corners of the square and b is at the opposite corner, the distance r1 is the length of a diagonal of the square:

r1=√(1.5²+1.5²)=2.12 cm

Substituting the values in the formula, we get:

V1 = 9×10^9×2.00×10^-6/2.12×10^-2V1

     = 84.5 V

The total electric potential at point b is the sum of the electric potentials due to q1 and q2:

V = V1+V2V

   = 84.5 + 0V

    = 84.5 V

The electric force exerted on a point charge by another point charge is given by Coulomb's law:

F=kq1q2/r²

where F is the force,

           q1 and q2 are the point charges,

           r is the distance between the charges,

           and k is the Coulomb constant.

Since q3 is negatively charged, it will experience a force in the direction opposite to the force experienced by a positive charge at the same location.

Thus, the total work done by the electric forces exerted by q1 and q2 on q3 can be calculated as the negative of the change in electric potential energy of q3 from point a to point b:

W=-ΔPE

where ΔPE is the change in potential energy of q3 from point a to point b.

Substituting the values, we get:

W=-q3(Vb - Va)

where q3=-5.00μC is the charge on q3,

           Va=0 is the electric potential at point a,

            and Vb=84.5 V is

the electric potential at point b:

W = -5.00×10^-6(84.5 - 0)W

   = -0.42 J

Therefore, the work done on q3 by the electric forces exerted by q1 and q2 is -0.42 J.

To form a triangle, the set of line segments must satisfy the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Therefore, we need to check if the given line segments 8 cm, 4 cm, and 3 cm meet this requirement.

We can start by checking if the sum of the two smaller sides (3 cm and 4 cm) is greater than the largest side (8 cm). 3 cm + 4 cm = 7 cm, which is less than 8 cm. Therefore, these three line segments cannot form a triangle.

In general, for a set of line segments to form a triangle, the largest side must be smaller than the sum of the other two sides. In this case, the line segment of 8 cm is too long compared to the other two sides, which makes it impossible to form a triangle.

In conclusion, there are no line segments that meet the requirements to form a triangle with lengths of 8 cm, 4 cm, and 3 cm.
