Answer:

y= -5/2x - -1

Step-by-step explanation:

1. Identify two points on the line

2. Select one to be (x1, y1) and the other to be (x2, y2).

3. Use the slope equation to calculate slope.

Final answer should be in the formula y=mx+b

The slope of the line passing through the points (0, -1) and (-2, -4) is calculated using the formula (Y2-Y1)/(X2-X1) and results in a slope of 1.5.

To find the slope of the line passing through two points, you can use the slope formula:

m = (Y2-Y1)/(X2-X1)

Applying this formula to the given points (0, -1) and (-2, -4):

Calculate the difference in the y-coordinates (rise): -4 - (-1) = -4 + 1 = -3.

Calculate the difference in the x-coordinates (run): -2 - 0 = -2.

Divide the rise by the run to get the slope: -3 / -2 = 1.5.

Thus, the slope of the line passing through the points (0, -1) and (-2, -4) is 1.5.

Step-by-step explanation:

If Jacob was given 45 Brazilian currency items for $55 you would need to divide 55 by 45 to see how much American dollars it would take to recieve one Brazilian currency.

For one Brazilian currency you need about (fig A) american currency for 1 brazilian currency.

The exchange rate for Brazilian real per American dollar for Jacob's transaction is approximately 0.8182 real per dollar, calculated by dividing the total amount of reals received by the dollars exchanged.

To calculate the exchange rate of Brazilian real per American dollar for Jacob's currency exchange, we divide the amount of Brazilian real he received by the amount of American dollars he exchanged. Jacob received 45 Brazilian real for $55 US dollars. The calculation to find the exchange rate is as follows:

It is important to compare this rate with the market rates mentioned, such as 35 cents/real or the government-set rate of 30 cents/real. It can be observed that Jacob's exchange rate is different from these rates, which illustrates how actual exchange rates may vary due to different factors such as service charges or varying rates across different currency exchange venues.

Answer:

y is going back by 3's x is going back one

Step-by-step explanation:

=======================================

Work Shown:

Let x = 5i-3

That allows us to go from (5i-3)(2i+1) to x(2i+1)

Distribute the x through: x*(2i) + x*(1) = 2i*x + x = 2i(x) + 1(x)

Now we replace every x in 2i(x) + 1(x) with 5i-3, and then we distribute a second time

2i(x) + 1(x) = 2i(5i-3) + 1(5i-3)

2i(x) + 1(x) = 2i(5i)+2i(-3) + 1(5i)+1(-3)

2i(x) + 1(x) = 10i^2 - 6i + 5i - 3

2i(x) + 1(x) = 10(-1) - i - 3

2i(x) + 1(x) = -10 - i - 3

2i(x) + 1(x) = -13 - i

Therefore, (5i-3)(2i+1) = -13 - i

The result is in a+bi form where a = -13 and b = -1.

------------------

An alternative method is to use the box method. This is where you set up a grid that helps you multiply out (5i-3)(2i+1)

See the diagram below.

Each of the 4 red terms in the boxes represents the result of multiplying the outer blue and green terms. Example: 5i times 2i = 10i^2 in row1, column1.

[tex]2d^2-d+5[/tex]

Step-by-step explanation:

The total number of burgers sold from a restaurant from Monday to Sunday:

[tex]f(d)=200d^3+542d^2+179d+1605[/tex]

The number of visitors to the restaurant from Monday to Sunday:

[tex]g(d)=100d+321[/tex]

To find the average number of burgers per person, just divide [tex]f(d)[/tex] by [tex]g(d).[/tex]

First, multiply [tex]g(d)[/tex] by [tex]2d^2[/tex] and subtract the result from [tex]f(d)[/tex]:

[tex]200d^3+542d^2+179d+1605-2d^2(100d+321)\\ \\=200d^3+542d^2+179d+1605-200d^3-642d^2\\ \\=-100d^2+179d+1605[/tex]

Then, multiply  [tex]g(d)[/tex] by [tex]-d[/tex] and subtract the result from [tex]-100d^2+179d+1605[/tex]:

[tex]-100d^2+179d+1605-(-d)(100d+321)\\ \\=-100d^2+179d+1605+100d^2+321d\\ \\=500d+1605[/tex]

Now, multiply  [tex]g(d)[/tex] by [tex]5[/tex] and subtract the result from [tex]500d+1605[/tex]:

[tex]500d+1605-5(100d+321)\\ \\=500d+1605-500d-1605\\ \\=0[/tex]

Hence,

[tex]f(d)=g(d)(2d^2-d+5)[/tex]

and the function

[tex]b(d)=2d^2-d+5[/tex]

represents the average number of burgers per person.

Answer:

12 bottles were sold in the second hour.

Step-by-step explanation:

This problem can be solved by implementing an equation in one variable.

The equation will utilize the given values including total bottles of juice, the amount of juice sold in the first hour and amount of juice remaining at the end.

The equation will also consist of the value to be found out, the amount of juice sold in the second hour.

The value to be found out is substituted by a variable.

The equation is then solved by transfer of values and/or variable on the opposite side of the equal sign.

When a value/ variable is transferred on the opposite side of the equal sign, the sign of the value/ variable becomes the opposite.

The negative sign becomes positive and multiplication becomes division, and vice-versa.

1. In the first hour, \frac{3}{15} of all the juice was sold.

\frac{3}{15} of 30 is calculated as

\frac{3}{15} x 30 = 6

6 bottles are sold in the first hour.

2. At the beginning of the second hour, the amount of juice remaining is assumed to be a.

3. As per the question, at the end of second hour, the remaining juice is \frac{6}{15}.

\frac{6}{15} of 30 is calculated as

\frac{6}{15} x 30 = 12

12 bottles are remaining at the end of the second hour.

4. Alternatively, at the end of second hour, 30 - 6 - a of the juice is remaining.

We get, 24 - a bottles are remaining at the end of the second hour.

We equate the above expression with 12, we get the following equation.

24 - a = 12

Next, we transfer a from left side to the right side of the equation.

24 = 12 + a

Next, we transfer 12 from right side to the left side of the equation.

24 - 12 = a

=> 12 = a

OR

a = 12

Hence, 12 bottles were sold in the second hour.

Mario sold 2/5 of his juice in the second hour after having sold 3/15 in the first hour and ending with 6/15 of the juice left.

Mario started with 30 bottles of juice and sold 3/15 of them in the first hour. To find out how many bottles that is, we multiply the total number of bottles by the fraction sold: 30 bottles x 3/15 = 6 bottles. After the first hour, Mario had 30 bottles - 6 bottles = 24 bottles left.

By the end of his shift, Mario had 6/15 of his original juice left. Again, we multiply the total number of bottles by the fraction left: 30 bottles x 6/15 = 12 bottles. So, at the end of his shift, Mario had 12 bottles unsold.

To find out how many bottles were sold in the second hour, we subtract the number left at the end from the number left after the first hour: 24 bottles - 12 bottles = 12 bottles sold in the second hour. To express this amount as a fraction of the original 30 bottles, we divide 12 by 30 to get 12/30, which simplifies to 2/5. Thus, Mario sold 2/5 of his juice in the second hour.

Answer:

mAngle2 = 50°

Step-by-step explanation:

A relative schematic has been attached bellow describing the problem.

In this case, we will be working with Supplementary angles. The latter denote angles which when summed together equal to 180°.

From the schematic we can identify the following Supplementary pairs as:

∠1 and ∠2

∠2 and ∠(18x+4)

∠(18x+4) and ∠(7x+1)

∠(7x+1) and ∠1

So lets start by finding the value of [tex]x[/tex] as follow. Since we know the supplementary pairs we have that

[tex](18x+4)+(7x+1)=180\\18x+7x+4+1=180\\25x+5=180\\25x=180-5\\25x=175\\x=\frac{175}{25} \\x=7[/tex]

Now we similarly know that ∠2 and ∠(18x+4) are supplementary. So lets replace the value of [tex]x[/tex] in ∠[tex]18x+4[/tex], we have

[tex]18(x=7)+4=126+4=130[/tex]

So finally we have

[tex]<2 + 130=180\\<2=180-130\\<2=50[/tex]

Thus we can say that ∠2 = 50° (which matches the second options from the available ones).

Answer:

40, 50, and 90

Step-by-step explanation:

You know that there are 180 degrees in a triangle, so you'd use the ratio to find each angle by setting up your equation like this: 4x+5x+9x=180

Then, simplify the equation and solve for x:

Then, plug 10 into each x value to find each angle measure:

4(10)=40, 5(10)=50, 9(10)=90

Final answer:

The measures of the angles in a triangle with a ratio of 4:5:9 are 40 degrees, 50 degrees, and 90 degrees respectively, calculated by dividing 180 degrees by the sum of the ratios and then multiplying by each individual ratio.

Explanation:

The question is asking us to find the measure of each angle in a triangle when the ratio of the angle measures is given as 4:5:9. To solve this, we will use the fact that the sum of the angles in any triangle is 180 degrees.

First, let's add the ratios together (4+5+9=18) to find the total number of parts that divide the 180 degrees. Now, divide the total degrees (180) by the number of parts (18) to find the measure of one part, which is 10 degrees. Then, multiply the value of one part by the number of parts for each ratio: 4 parts, 5 parts, and 9 parts.

The measure of the first angle (4 parts) is 4 x 10 = 40 degrees, the second angle (5 parts) is 5 x 10 = 50 degrees, and the third angle (9 parts) is 9 x 10 = 90 degrees. Hence, the measures of the angles in the triangle are 40 degrees, 50 degrees, and 90 degrees respectively.

1) The work done is 1000 J

2) The kinetic energy is 600 J

3) There is a continuous conversion between kinetic and potential energy

Step-by-step explanation:

1)

The work  done by a force when pushing/pulling an object is given by

[tex]W=Fd cos \theta[/tex]

where

F is the magnitude of the force

d is the displacement

[tex]\theta[/tex] is the angle between the direction of the force and of the displacement

In this problem, we have:

F = 50 N is the force

d = 20 m is the displacement

[tex]\theta=0[/tex], assuming the object is parallel to the displacement

Substituitng,

[tex]W=(50)(20)(cos 0)=1000 J[/tex]

2)

The kinetic energy of an object is the energy due to the motion of the object. It is given by

[tex]K=\frac{1}{2}mv^2[/tex]

where

m is the mass of the object

v is its speed

For the object in this problem,

m = 12 kg is the mass

v = 10 m/s is the speed

Substituting, we find

[tex]K=\frac{1}{2}(12)(10)^2=600 J[/tex]

3)

Here the skateboarder is moving on the half-pipe. According to the law of conservation of energy, the total mechanical energy, sum of kinetic and potential energy, is conserved:

[tex]E=KE+PE=const.[/tex]

This means that:

Therefore, there is a continuous conversion between potential and kinetic energy.

Answer:

1. W = Fs

W = 50 N  20 m

W = 1,000 J

2. Ek=mv22

Ek=12kg×(10m/s2)2

Ek=12×1002

Ek=1,2002

Ek = 600 J

3. At point A, the skateboarder’s energy is all potential since she is high up (PE = mgh), and gravity has the potential to pull her down. She isn't moving, so she doesn't have velocity. Therefore, she doesn't have kinetic energy. At point B, she is moving the fastest during her ride and is as close to the ground as the ramp allows. Thus, her potential energy has been turned into kinetic energy due to her velocity and lack of height. At point C, if she comes to a stop on the other side of the half-pipe, her kinetic energy has been turned back into potential energy since she is high up again.

4. Eventually, the friction between the wheels and the ground will cause the skateboard to stop. Each time she goes back and forth, she will lose some of her initial energy from her drop-in, as long as she doesn't push off the sides at all.

We are given an information as:

1. 25 students play an instrument.

2. 20 students are in band.

3. 20 students are not in band

Hence, the table can be formed as:

                                               Band          Not in Band        Total

Play instrument                    20                     5                   25

Total                                     20                      20                40

Since, those who don't play any instruments can't even play band hence the value of that in table is 0.
