Find the equation of the straight line which passes through the point (2,3) and is
inclined at 30° to the positive direction of the x-axis.

Answers

Answer: y = 1.73*x - 0.46

Step-by-step explanation:

For a linear equation of the form:

y = a*x + b

Where a is the slope and b is the y-intercept.

If we have an angle of A degrees with respect to the x-axis, the slope of the function can be calculated as:

Tan(A) = a.

in this case, we have we have an inclination of 30° to the positive x-axis (measured from the positive y-axis) and we know that the angle between the positive x-axis and the positive y-axis is 90°, then the angle measured from the positive axis will be such that:

A + 30° = 90

A = 90° - 30° = 60°

Then the slope is:

a = Tan(60°) = 1.73

Then we have the equation:

y = 1.73*x + b

And we know that this line passes through the point (2, 3) then we can replace x by 2 and y by 3 in the equation, and find the value of b.

3 = 1.73*2 + b

3 - 1.73*2 = b = -0.46

Then the equation is:

y = 1.73*x - 0.46

Answers

Answer:

x=13

Step-by-step explanation:

According to the question

3x+5x-14=90

8x-14=90

8x=90+14

8x=104

x=104/8

x=13

180 = 90 + 3x + 5x - 14
180 - 90 + 14 = 3x + 5x
104 = 8x
104/8 = x
x = 13

Checking:
3(13) + 90 + 5(13) - 14 = 180
180 = 180
So x=13

Solve the equation for m. Show your work on the canvas. Move -n by using opposite operation. Then just write the equation as is. This is a one step equation. 4=m−n

Answers

Answer:

m = 4+n

Step-by-step explanation:

Given the expression 4 = m-n, we are to make m the subject of the formula

From the equation

4 = m-n

Rearrange

m-n = 4

Add n both sides of the equation

m-n+n = 4+n

m+0 =4+n

m = 4+n

Hence the expression for m is given as m = 4+n

write an equation in slope-intercept form perpendicular to the given equation through the given point
Y = -3x + 4
(6,-2)

Answers

Answer:

y = (1/3)x - 4

Step-by-step explanation:

Any line perpendicular to the given equation y = -3x + 4 will have a slope which is the negative reciprocal of -3; that is, +1/3.

Start with the general slope-intercept form y = mx + b.

Insert the coordinates 6 and -2 into y = mx + b:  -2 = (1/3)(6) + b, or

-2 = 2 + b.  Thus, b = -4, and the desired equation is

y = (1/3)x - 4

Mary Beth could jump 42 times each minute. How many times could she jump in two hours explain to me step by step

Answers

if mary beth jumps 42 times per minute you need to figure out how many minutes in 2 hours (120 minutes). 42x120=5,040

Answer:

5,040 jumps

Step-by-step explanation:

Let's figure out the number of jumps per hour

42 steps/minute * 60 minutes/hour = 2,520 jumps/hour

Mary Beth is jumping for 2 hours, so we need to multiply by 2 hours.

2,520 jumps/hour * 2 hours = 5,040 jumps

It takes 900 pounds of steel to make one steel beam. How many beams can be made from 6,300 pounds of steel?

Answers

Answer:

7

Step-by-step explanation:

6,300 divide by 900 would equal 7

Answer:

7 beams

Step-by-step explanation:

To find how many beams can be made from steel, we have to find how many times 900 goes into 6,300. So our equation is:

6,300 ÷ 900 = 7

So you can make 7 beams out of 6,300 pounds of steel (and you won't have any steel left.)

What was known twenty years ago was even more imperfect, and the science of fifty years ago hardly worth knowing. Using a little imagination, we can ask what will become of the science of today, some twenty or thirty years from now? Unless the rate of scientific advance shows a notable slacking off (and there are no signs of this) our best knowledge of today will become decidedly frowsy1.Since scientists have such overweening confidence in their own abilityin their collective ability, that is to sayit is no small wonder that they make no attempt to teach what are the limitations of science, for they hardly recognize any.Yet there may be limits to what science can do. Consider this question: Can science disprove ghosts? In the supremely confident period, toward the end of the last century, when it was supposed that there was a conflict between Science and Religion, and Science was rapidly winning, it was the mark of an educated man to say Science has proved that there are no such things as ghosts, they are merely the superstitions of the unenlightened. Education is always behind the times, and much the same attitude is prevalent today; you can still hear people say, Surely, science has proved that there are no ghosts. And yet, is that so? Suppose, just suppose for the sake of argument, that ghosts can occasionally appear when the psychological conditions are just right, and suppose, what might quite well be true, that one necessary condition for the appearance of a ghost is the absence of a scientist: well then, Science (that is to say, scientists) would go on investigating ghost after ghost, and would disprove every one of them, and yet ghosts would continue to appear whenever the scientists were not looking.This is a simple case, perhaps not a very important one, illustrating the impossibility of proving anything negative by the scientific method. At least it is enough to show that science is not infallible, and if science has any more serious defects than the inability to perceive an occasional spook in the corner, it is of the utmost importance that citizens, generally, should know what they are. Yet this sort of knowledge is very conspicuously absent from the populace at large and from the curriculums of institutes of learning. Non-scientists dont even know what science can do; scientists are so obsessed with the past successes and future possibilities of their own specialty that they have no idea what the proper field of science in general is and no recognition that there are any limits. What they cant do, some other scientists, presumably, can do, so that they come to think that science with a capital Sor rather its concentrated and distilled essence, the Scientific Methodis the universal cure-all for mankind.They are wrong, for science is not a cure-all. The claims of the science fiends are preposterously exaggerated. Science has many important limitations, which will appear throughout this book in ever-increasing number. The idea that science is infallible and beyond criticism is a delusion, and even a dangerous one. The teaching of science only perpetuates this delusion, for it is always taught by scientists, who are so busy keeping up with science that they can never look at it from the outside. What with scientists who are so deep in science that they cannot see it, and non-scientists who are too overawed to express an opinion, hardly anyone is able to recognize science for what it is, the great Sacred Cow2 of our time.John Dewey, a worshiper in the temple of science, said the future of our civilization depends on the widening spread and deepening hold of the scientific habit of mind.
