Having minor homework questions or simply want to make sure your homework answers are correct? Then use our free service to get quick answers to your homework questions in mathematics, physics, programming, economics, chemistry and biology. We already have a database of multiple homework questions and answers you can look through . If you can’t find the solutions to your homework problems, then post your homework questions and find a well-formulated answer from a professional within a very short timeframe.
Please save your time and DO NOT send us your full assignments or not precise, well stated questions in mathematics, physics, programming, economics, chemistry or biology as they will be ignored. In this section we can answer only your short questions of qualitative, primary theoretical nature (for FREE!). Use filters to display the questions to a particular subject or section. By entering your e-mail in the box "Search" you can browse the questions posted exclusively by you.

You and a friend are playing a game of squirt-gun tag in a maze. Suddenly you see your friend's image in a small planar mirror. You take a shot over the barrier in front of you and find that your friend is just at the end of the 7.0 m range of your squirt gun. If you are 4.0 m from the point of reflection of the light ray, how far from the point of reflection of the light ray is your friend? answer in meters please.
Two mirrors are placed at a 90° angle to each other. A light ray strikes one mirror 0.620 m from the intersection of the mirrors with an incident angle of 36.5°. The ray then travels a distance d before reflecting from the second mirror. (a) What is the distance d? answer should be in meters.
A mirror creates an image of magnification −1/3. (a) Is the image upright or inverted? (b) If the object is 7.75 cm tall, what is the height of the image? State your answer with the correct sign. all answers should be in cm. thanks.
You look into a shaving mirror and the upright image of your face is 40.0 cm away from you. The image has a magnification of 1.50. (a) How far away are you from the mirror? (b) What is the radius of curvature? all answers should be in cm. thanks.

Students Per Computer In the early years of microcomputers,
school districts could not afford to buy a computer
for every student. As the price of computers decreased,
more and more school districts have been able to attain
this goal. The following table lists numbers of students
per computer during these early years.
(a) Make a scatterplot of the data. Would a straight line
model the data accurately? Explain.
(b) Discuss how well the formula
models these data, where S represents the students per
computer and y represents the year.
(c) In what year does the formula reveal that there were
about 17 students per computer?

How do you read values from a trigonometric period function has period 4 Pi / 3 and range [-1,1] ?
Can mass be measured in the absence of force (4 fundemental forces)? in complete isolation can a mass of an object be determined?
if yes how?
if not... then how can we define that the object even exists in absolute isolation ?
thank you
The following points appear in the edge profile (Gradient image, G[x, y]) [3,4],[6,8],[7,11],[9,13],[11,15].
Draw the corresponding lines in m-c parameter space using value range for m [0...1]. Quantize c values in unit steps and m into steps of 0.1, 0.2 and so on. Deduce which is the best fit line, y = mx + c, and how many cross-sections at the cluster it has.
