Since we are given two points in the graph, we can use the slope equation shown below:

(y2-y1)/(x2-x1)

reading the graph left from right (1,11) will be the first point and (3,1) the second. plug in and solve!

(1-11)/(3-1) = -10/2 = -5

The slope is -5

a negative slope makes sense since the graph is leaving the first quadrant.

hope this helps!

Answer: A) -5. Graph slope.

Step-by-step explanation:

The formula to calculate the slope of the line is:

[tex]\boldsymbol{\sf{m=\dfrac{\Delta y}{\Delta x} \iff m=\dfrac{x_2-x_1}{y_2-y_1} }}[/tex]

We have that the points are:

We substitute these points in the previous formula and solve:

     [tex]\boldsymbol{\sf{m=\dfrac{x_2-x_1}{y_2-y_1} }}\\ \\ \\ \boldsymbol{\sf{m=\dfrac{1-11 }{3-1} }}\\ \\ \\ \boldsymbol{\sf{m=\dfrac{-10}{5} }}\\ \\ \\ \boxed{\boldsymbol{\sf{m=-5}}}[/tex]

Answer:

The minimum length and width of the tarp would be the diagonal length of the café's piece of ground. To find this length, you can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides. In this case, the café's piece of ground forms a right triangle, with one side measuring 6.0 m and the other side measuring 5.0 m. So, to find the length of the hypotenuse, we can use the formula: c = √(a^2 + b^2) where c is the length of the hypotenuse and a and b are the lengths of the other two sides. Plugging in the numbers, we get: c = √(6.0^2 + 5.0^2) = √(36 + 25) = √(61) = 7.81 m

So, the minimum length and width of the tarp would be 7.81 m.

Step-by-step explanation:

a/b is invalid, when b = 0.

so, F(x) is invalid, if (1 + sin(2x)) = 0.

(1 + sin(2x)) can only be 0, if sin(2x) = -1

sin(angle) = -1

angle = 2x = 270° or 3pi/2

x = 135° or 3pi/4

so,

The volume of the rectangular prism is  10a⁵ - 30a⁴ + 10a³. Option A

The formula for determining the volume of a rectangular prism is expressed as;

Volume = l × w × h

Given that the parameters are;

We also have their values as;

Length, l = 5a

Width = 2a

h = (a³- 3a² + a)

Substitute the values, we get;

Volume = (5a . 2a. a³- 3a² + a)

Volume = 10a⁵ - 30a⁴ + 10a³)

Since they have different powers, it is impossible to add the like terms

Answer: the estimated maintenance cost of cars when the age of cars is 12 years is 16.5 ( in 100 birr)

Step-by-step explanation:

To obtain the regression equation for costs related to age of cars, we can use the method of least squares. This method involves finding the line of best fit that minimizes the sum of the squared differences between the predicted values and the actual values.

The equation for a linear regression line is:

y = a + bx

where a is the y-intercept and b is the slope of the line.

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

b = (n(∑xy) - (∑x)(∑y)) / (n(∑x^2) - (∑x)^2)

To find the y-intercept (a), we can use the formula:

a = (∑y - b(∑x)) / n

Given the data provided, we can calculate the following values:

∑x = 142

∑y = 150

∑xy = 2430

∑x^2 = 10304

n = 8

By substituting these values into the formulas for b and a, we can find the slope and y-intercept of the line:

b = (8(2430) - 142(150)) / (8(10304) - 142^2) = 0.5

a = (150 - 0.5(142)) / 8 = 13.5

Therefore, the regression equation for the costs related to age of cars is:

y = 13.5 + 0.5x

To estimate the maintenance cost of cars when the age of cars is 12 years, we can substitute x = 12 into the equation and solve for y:

y = 13.5 + 0.5(12) = 16.5

So the estimated maintenance cost of cars when the age of cars is 12 years is 16.5 ( in 100 birr)

El banco recibió 128 rollos de monedas de 10 centavos.

Step-by-step explanation:

Para saber cuantos rollos de monedas de 10 centavos recibió el banco, podemos dividir el total de monedas recibido entre el número de monedas por rollo.

(1 024 monedas) / (8 monedas/rollo) = (x rollos)

Donde x es el número de rollos recibido. Para calcular x se divide 1 024 entre 8

x = 1 024 / 8

x = 128

Answer:

Ryan

Step-by-step explanation:

Let's calculate the probabilities of John and Ryan hitting the target center

Let P(J) and P(R) be the respective probability representations

For John

John hits the center 1 time for every 3 tries(arrows)
Therefore

[tex]P(J) = \dfrac{1}{3}[/tex]

Out of 30 arrows (and therefore 30 attempts)  the expected number of times that John can hit the center is given by

[tex]30\cdot \dfrac{1}{3} = 10\\[/tex]

Since you need to hit the center more than 10 times, John is not expected to win the merit badge

For Ryan

Ryan Hits the center 2 times for every 5 arrows (attempts)

[tex]P(R) = \dfrac{2}{5}[/tex]

With 30 arrows the expected number of times that Ryan hits the target is:
[tex]30\cdot \dfrac{2}{5} = 18\\\\[/tex]

So Ryan is expected to win the Archery Merit Badge.

Important Note

Here you have to be careful of the words you use and interpret the results with some reality checks.

Probabilities after all are based on previous trials and represent only an estimate of guarantees of future events. That's why I have repeatedly used the word expected.

After all, John maybe able to hit the center a 11th time and thus he too will earn a merit badge.

In my opinion a poorly worded question

The area of the triangular side of the pyramid is given as follows:

21,852 m².

We consider that the side of the pyramid is triangular, hence we must consider that the area of a triangle is obtained as half the multiplication of the base by the height, that is:

Area = base x height / 2.

Considering b = 233, and dividing by the square root of 2, the coordinates of the endpoints of the base are given as follows:

(164.76, 0, 0) and (0, 164.76, 0).

Hence the length of the base is obtained using the distance between two points as follows:

Base = [tex]\sqrt{164.76^2 + 164.76^2}[/tex]

Base = 233.

The midpoint of the base has the coordinates given as follows:

(82.38, 82.38, 0).

The height is the distance between (0,0,147) and (82.38, 82.38, 0), hence it is given as follows:

Height = [tex]\sqrt{82.38^2 + 82.38^2 + 147^2}[/tex]

The value of the expression - 9(18 - 9 + 12) + 12(- 9 + 18 + 18) is 135.

If a system of equations only contains two linear equations with two variables, the system's equation can be graphed, the graph will have two straight lines, and the intersection point(s) of those lines will be the system's solution.

There are only three matching forms of solution for a given system of equations because there are only three different ways that two straight lines in the plane can graph.

Let, The rectangle be x, the triangle by y, and the star be z.

Therefore,The three linear equations are,

x + 3y + z = 57...(i)

12x + 5y = 234...(ii)

8x - 6x + 3x = 60...(iii)

5x = 60.

x = 12.

Putting the value of x in eqn(ii) we have,

12(12) + 5y = 234.

144 + 5y = 234.

5y = 90.

y = 18.

Now, Putting the value of x and y in eqn(i) we have,

12 + 3(18) + z = 57.

12 + 54 + z = 57.

z = - 9.

So, The value of the expression z(y + z + x) + x(z + y + y) is,

= - 9(18 - 9 + 12) + 12(- 9 + 18 + 18).

= - 9(21) + 12(27).

= - 189 + 324.

Answer:

m∠ABC = 180.

Step-by-step explanation:

In a triangle, the median to the side opposite the largest angle bisects that angle.

Since BM is a median, it bisects ∠C, the angle opposite side AB.

Let's call the angle opposite side AB angle x, so x/2 = 40.

Therefore, x = 80

Since a triangle has 180 degree, then if we add all the angles in the triangle we get:

m∠ABC = m∠BAC + m∠BCA + m∠CAB = x + (180-x) + (180-x) =180

So m∠ABC = 180

This is a quadratic function, which is a function of the form f(x) = ax^2 + bx + c, where a, b and c are constants. The function can be written in general form as f(x) = (x-4) / (x^2 +13x + 36).

To find the roots of the function (i.e. the points at which the function intersects the x-axis), we can use the quadratic formula:

x = [-b +/- sqrt(b^2 - 4ac)] / 2a

In this case, a = 1, b = 13 and c = 36.

Substituting these values into the quadratic formula, we get:

x = [-13 +/- sqrt(169 - 4(1)(36))] / 2

x = [-13 +/- sqrt(97)] / 2

x = [-13 +/- 9.8488578] / 2

x1 = -1.1744289

x2 = 11.1744289

Therefore, the roots of the function are x1 = -1.1744289 and x2 = 11.1744289.

11x = 99z

x = 9z

3y = 99z

y = 33z

1x + 1y + 1z = 9z + 33z + 1z = 43z

In given fractions 8/9 is 1/36 large than 31/36

Finding the larger and smallest fraction in between two or more fractions is known as comparing fractions.

We need to change fractions with unlike denominators into fractions with similar denominators in order to compare them. For this, we will find the denominators' Least Common Multiple (LCM).    

If the denominators are the same then it is easy to compare the fractions.

Here we have

31/36 and 8/9

To find the largest fraction convert both denominators into the same  

Here LCM(36, 9) = 36  

Now multiply both numerator and denominators of fractions with a number to change the denominators  

=> [tex]\frac{31}{36} \times \frac{1}{1} = \frac{31}{36}[/tex]  

=> [tex]\frac{8}{9} \times \frac{4}{4} = \frac{32}{36}[/tex]

Step-by-step explanation:

Answer:

The compound interest formula is A = P(1 + r/n)^(nt) where A is the final amount, P is the principal (initial deposit), r is the annual interest rate (expressed as a decimal), n is the number of times interest is compounded per year, and t is the number of years.

In this case, P = 2750, r = 0.035, n = 4 (because interest is compounded quarterly) and t = 7 (because we are trying to find the balance after 7 years).

So the formula becomes:

A = 2750(1 + 0.035/4)^(4*7)

By plugging the number into the formula we can find the final amount after 7 years

A = $3,974.23

So the amount of money in the account at the end of 7 years is $3,974.23, rounded to the nearest hundredth.
