First find the slope m. slope formula: [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

Let's use (0, -20) for x1 and y1; and (2, 10) for x2 and y2

[tex]\frac{10-(-20)}{2-0}[/tex] = [tex]\frac{30}{2}[/tex] = [tex]15[/tex]

Now find the y-intercept: the point where the graph crosses the y-axis. The y intercept always has an x value of 0. So -20 is the y-intercept

Use the slope formula [tex]y = mx + b[/tex]. Slope=m, y-intercept = b

Answer:

Angle BAC = 62.35

Step-by-step explanation:

Here, we want to get the angle marked BAC

From the diagram, we have the angle ABC as 90

This is because angle at the center is twice the angle at the circumference

Furthermore, using the arc angle relationship;

angle ACB is half arc AB

so ACB angle is 55.3/2 = 27.65

mathematically;

Angle BAC + 27.65 + 90 = 180

This is because sum of angles in a triangle is 180

Thus;

angle BAC = 180-90 - 27.65

angle BAC = 62.35

Marco located the falllow points on a number line which point is not corrtly placed on the number line

Answers

Question:

Marco plotted the following points on the number line.

Point A: 0.3 Point B:  3/4 Point C: 11/4 Point D: 0.7

Which point did he plot incorrectly?

Answer:

Point D

Step-by-step explanation:

Given

[tex]Point\ A= 0.3[/tex]

[tex]Point\ B= \frac{3}{4}[/tex]

[tex]Point\ C= \frac{11}{4}[/tex]

[tex]Point\ D= 0.7[/tex]

Required

The incorrectly plotted point

Number plotted on a number line increases from left to right. This implies that:

[tex]A < B < C < D[/tex]

Substitute the values for the given points

[tex]0.3 < \frac{3}{4} < \frac{11}{4} < 0.7[/tex]

Express as fractions

[tex]0.3 < 0.75 < 2.75 < 0.7[/tex]

Up till 2.75, the order of the numbers is correct.

However, 0.7 is less than 0.75 and 2.75

So, 0.7 is not placed correctly.

This implies that point D is not correctly placed

Hello There!

The area of a rectangle is equal to length times width

If a triangle is formed in a rectangle then that triangle is 1 half of the area of the rectangle

AD  =  DE / sin (55)

AD  =  8 / sin (55)

Answers

Answer: 52.5cm²

Step-by-step explanation:

Firs, you have to split this composite shape into two separate shapes; a rectangle and triangle.

To work out the area of the rectangle you would have to do 8x5=40.

To work out the area you would have to find out the height of it first. So, to do this you would have to do 1+2=3 then do 8-3=5. Now we know the height is 5.

Then you have to use the formula base times height divided by 2 (b×h/2). So 5×5=25 then 25÷2=12.5

To then find the total area of this composite shape you would have to add the two areas together. So 40+12.5=52.5cm²

Hope this helps :)

Two buses depart from the Hillsboro Bus Terminal. One is moving north at 35 miles per hour, while the other is moving south at 48 miles per hour. How long will it be before the buses are 48 miles apart

Answers

Answer:

3.6 hours.

Step-by-step explanation:

Given that Two buses depart from the Hillsboro Bus Terminal. One is moving north at 35 miles per hour, while the other is moving south at 48 miles per hour. How long will it be before the buses are 48 miles apart

Since they are moving in opposite directions to each other, let us first calculate the relative velocity.

Relative speed = 48 - 35 = 13 mph

Using the formula

Speed = distance/time

Substitute all the parameters into the formula

13 = 48 / time

Make time the subject of the formula

Time = 48 /13

3.69 hours.

Therefore, before the buses are 48 miles apart, the time taken will be 3.6hours.

Also, it is very debatable whether using animals for such research results in finding a cure for diseases. From my point of view, if there are no other alternatives, and if it is possible that this will contribute to science, animals may be used for experimental research.Although the animal rights activists claim that people and animals are equal and thus they should be treated equally, I think that people and animals cannot be seen equal, and therefore the death of an animal cannot be the same thing as the death of a person. For that reason, causing animals to die for science, for the sake of saving human lives, may be considered ethical to some extent if it will contribute to the advancement of science and will be to the benefit of humanity in general.Furthermore, animal rights supporters label scientists as cruel for causing animals to die in medical experiments, while they do not oppose the people, mostly farmers, who kill animals for food, even though they know that 99% of animals deaths is caused by farmers while only a small percentage, i.e. 1% is caused by scientists. The underlying reason for that is they find scientists easier to attack and cannot deal with farmers who are organized and strong.Another basic argument of animal rights defenders is that people and animals are different genetically and therefore it is useless to use animals in experiments to see the effects of some substances on people. They claim that it will make no good to use animals in experiments because they are too different to be compared to people. Some of them even assert that it is better to use people directly as they think that the results of experiments on animals cannot be valid and reliable as long as the same observation has not been done on man also. However, these people cannot foresee the disastrous results of such a practice. Many people are likely to die until a healthy result is obtained.People and animals may not be the same, but to some degree there are similarities which can at least give scientists an idea about their experiments. From this point of view, scientists are right to use animal models to provide themselves with information about what is happening at level of detail that could not be achieved in humans. Although there might have been some incidents when animal testing did not prove to be useful and some effects of some drugs observed on animals could not be observed on people, there are also a lot of examples that show that using animals resulted in significant developments and helped to cure some serious illnesses.On the other hand, there may be alternative methods that should be used instead of animal experimentation. Then, of course, it is cruel and unethical to use animals. For example, in some experiments in-vitro methods can be used as an alternative to using live animals. In such occasions, it is certainly much better and right to employ these alternatives.All in all, it can be said that using animals for medical research is ethical a long as it contributes to scientific development and helps scientists find ways to improve human health. And this practice is only acceptable on the condition that necessary pains are taken and animals are treated humanely.
