1) Kevin is projecting the picture of a purple square on a wall. As he moves the projector and further away from the wall its image gets larger and larger.

a. If a cm (squared) is the area of the square and e cm is tis edge lenth, then equation describes the relation between the dependant variable A cm square and the independent variable E cm.

Answer________

b. what do we call the way a varies with e?

Answer__________

2) The distance D meters, that an object fall, t seconds after it has been dropeed, os ... D = 1/2gt(square), where g is the constant 9.8

a. What is the name for the way d varies with respect to t

3) Express each of the following so that there are no exponents

a. 27 2/3 (this is the square in the example

b. (1.1 1/2)squared

4) Some students have decided to pool their money together and buy lotto tickets. Suppose that, together they won 1000 dollars, which they distribute equally among all those who bought tickets. Suppose the number of students who bought tickets is X and $Y is the moaunt of dollars given to each of these X students

a. What is the name for the way that y varies with with respect to X?

I'm sorry, but I have no idea what this means.

1) Kevin is projecting the picture of a purple square on a wall. As he moves the projector and further away from the wall its image gets larger and larger.

a. If a cm (squared) is the area of the square and e cm is tis edge lenth, then equation describes the relation between the dependant variable A cm square and the independent variable E cm.

I'm sorry, but this is not a complete sentence, and it would appear that information has been omitted. Please proof and reply with corrections.

b. what do we call the way a varies with e?

See reply to (a).

2) The distance D meters, that an object fall, t seconds after it has been dropeed, os ... D = 1/2gt(square), where g is the constant 9.8

a. What is the name for the way d varies with respect to t

Do you mean "D", or is there some other variable "d" that has been omitted from the above statement of the exercise. (In mathematics, "D" and "d" are not the same variable.) What sorts of "variation" have you learned?

3) Express each of the following so that there are no exponents

a. 27 2/3 (this is the square in the example

I'm sorry, but I don't know what you mean when you say that "this is the square in the example". What example? Also, you have posted "twenty-seven and two-thirds", which has no exponents. What is to be simplified?

b. (1.1 1/2)squared

I'm sorry, but your formatting is quite confusing. Do you mean the following:

. . . . .(11¹/₂)²

(I'm afraid I don't understand the "one-point-one and one-half notation you are using. Is the "point" supposed to be there, or was that just another typo?)

4) Some students have decided to pool their money together and buy lotto tickets. Suppose that, together they won 1000 dollars, which they distribute equally among all those who bought tickets. Suppose the number of students who bought tickets is X and $Y is the moaunt of dollars given to each of these X students

a. What is the name for the way that y varies with with respect to X?

I will assume that "y" actually means "Y".

What sorts of "variation" do you have? Which one would match "more input leads directly to more output"?

I'm sorry, but I don't understand this remark. Did somebody tell you that this tutoring forum wasn't actually a tutoring forum, but was a math-challenge group?

Please reply with clarifications. Thank you.
