1. ### Determine the area in sq ft of a yard, only knowing the distance around it

Hello all, This particular problem is a practical problem I have. The shape of my yard is not a perfect cylinder. If you were to fly over it at a low altitude it would look like a beaker that has it's funnel glass bent to the right. So, it definitely looks like a beaker with the base of the...
2. ### Defining a formula to determine the relationship and positioning 3 moving averages

Hi, I have 3 moving averages. 2 define a channel (high/low) and the 3rd constantly moves within the high/low channel. I'm trying to create a formula that represents the relationship between the 3 moving averages but I don't know how to achieve this. Could someone suggest how I go about this...
3. ### determine whether the equation is linear or not

the answer is yes , and the ans is y = A(x+1) , how to get the ans ? i could only get dy/dx = y / (x+1) anyone can help ?
4. ### Determine the following set in interval form

i have this very rare problem for me in interval... can anyone help me on this please.. thank you
5. ### Determine which side a point is on

Im working on a small 2d game in c++ and am not sure on how to make a formula for my problem. I have a point that moves with a velocity in any direction and another point that is static. I need to determine which side the static point is on, to the moving point. ie Left or Right I made a...
6. ### determine the equation of the tangent line at x=1

It is given that e^(xy)=x[(x+1)^3] / (x^2+1) ,where x>0 determine the equation of the tangent line at x=1 my work::::::::xy ln e=lnx+3ln(x+1)-ln(x^2+1) d/dy (xy ln e)=d/dy [(lnx+3ln(x+1)-ln(x^2+1)] dy/dx(1/e)=1/x+[3(1/(x+1))]-[2x/(x^2+1)] dy/dx =e*(1/x+[3(1/(x+1))]-[2x/(x^2+1)]) I know it is...
7. ### Any algebraically way to determine if definite integral is proper or improper ?

After successfully computing several definite integrals I want to specify if the definite integral is either proper or improper. To my understanding it is easily determined if the boundaries are either positive or negative infinity, but when they are not, I have to determine if the function is...
8. ### Using integral test to determine whether a series converges or diverges

In this example theres three conditions before we can use the integral test, it needs to be continuous, positive decreasing function. I plugged in the series in my graphing calculator, it's continuous, positive, but not decreasing from n=1 to infinity. It stays at zero for n>= 16. So Instead, I...
9. ### Determine the equation of a tangent line

1. Determine the equation of the tangent line 2x^3 + 10x^2-28x at x = -3. I found the derivative and ended up finding the instantaneous rate of change through the secant formula f(a+h) - f(a)/h. I'm pretty sure that's not correct (Worried), can someone please show me how to do this?
10. ### Determine whether linear, quadratic or exponential...

1. Determine whether linear, quadratic or exponential... This is what I got for 0 to 5: http://www.wolframalpha.com/input/?i=%280%2C2.7%29%281%2C4.1%29%282%2C1.5%29%283%2C-5.1%29%284%2C-15.7%29%285%2C-30.3%29+ This is what I got for 5 to 9...
11. ### Determine if sequence converges or diverges using l'Hopital's Rule

Can we use l'Hopital's Rule as another alternative in solving this problem like how I showed in my work?
12. ### Determine the p-value

Hello Someone who can help me with this question?: 1. Given the following hypotheses, determine the p-value when x̅ = 21, n = 25, and σ = 5. H0: μ = 20 H1: μ ≠ 20 2. Repeat part (a) with x̅ = 22. Thanks in advance.
13. ### Determine whether the sequence converges or diverges

I have the sequence: I found that it converges to 0, and I checked in the back of the book and that was correct, but I want to make sure my reasoning is correct. I took the highest powers to be e^n/e^2n which is just equal to e^-n, so the limit as n goes to infinity would just be 0. I'm not...
14. ### Determine the taxable income, to the nearest penny, for an individual filing joint...

1. Determine the taxable income, to the nearest penny, for an individual filing jointly who pays a tax of $546.37. 2. If an individual filing jointly pays a tax of$278.36, determine the taxable income. Express your answer to the nearest cent. 3. If an individual’s taxable income is \$6,300...
15. ### Graph the function given below and determine the given functional values.(Updated)

I do not understand how both of those are graph I liked, I realize that the one lower near (3,-3) is a parabola and opens upward, but how do I get it from that? Also what do the three functions have to do with this? I have my exam tomorrow, this is the only question I really do not fundamentally...
16. ### Graph the function given below and determine the given functional values.

f(x)={(3-x)^2 -4 if x=<; f(-3), f(3), f(6) ------{ 5 if x>3; So does it want me to plug in the 3 function of x's given? I am not sure what it is asking for.
17. ### Determine Range and function of the graph.

I am having trouble determining the range and function, is it simply just the x and y of the graphs? And determine the possibilities of them. The domain is : (-7,-5)U(-5,3)U(3, positive infinity) The Range is [-7,7)U(7, positive infinity) How do they get those answers??
18. ### Determine whether the function is odd even or neither

I am having a hard time trying to wrap my head around this, I think it's because a bathtub landed on my head this morning, but can you help me understand this concept? I always assumed Tan was a negative identity, but I am at a loss for how to do the operations to arrive at an answer...
19. ### Determine the Point(s)

Determine the point(s) at which the graph of the function has a horizontal tangent. f(x) = (e^x)(sin x) in the interval [0, pi]. Same as the other question. I don't know where to start. I need the steps that will guide me safely through to the correct answer.
20. ### Determine the Point(s)

Determine the point(s) at which the graph of the function has a horizontal tangent. f(x) = (x^2)/(x^2 + 1) I need the steps. You know, step 1 do this, step 2 do that, etc. I don't know where to start.
