Question

I want you to solve a integral question with substitution method and double integrals and explain each step what you did.Thanks

Answer #1

ONLY use method of alligation to solve the
problem. I already know the answer, I want to know how to solve it
with alligation. IF YOU DON'T KNOW WHAT ALLIGATION IS, DON'T ANSWER
THE QUESTION. THIS IS FOR A PHARMACY EXAM.
A health food store sells a mixture of raisins and roasted
nuts. Raisins sell for $3.50/kg and nuts sell for $4.75/kg. How
many kilograms of each should be mixed to make 20 kg of this snack
worth $4.00/kg? ONLY...

Explain whether the following integrals converge or not. If the
integral converges, find the value. If the integral does not
converge, describe why (does it go to +infinity, -infinity,
oscillate, ?)
i) Integral from x=1 to x=infinity of x^-1.4 dx
ii) Integral from x=1 to x=infinity of 1/x^2 * (sin x)^2 dx
iii) Integral from x=0 to x=1 of 1/(1-x) dx

Evaluate the indefinite integral using Trigonometric
Substitution. Make sure to show all your work, and explain why/what
you are doing at each step. Include all relevant diagrams. If you
would prefer to narrate your explanation instead of typing it, that
is a possibility. ∫ 22? 2 √49−? 2 ?x

Trig integration. Evaluate the indefinite integral using
Trigonometric Substitution. Make sure to show all your work, and
explain why/what you are doing at each step. Include all relevant
diagrams. ∫ 22?^2/√(49−?^2)??

Evaluate each integral in and explain why you used the method
you did.
∫ ???(? + ?2) ??, where ? is the perimeter of a
square with
vertices?1 =?+?, ?2 =−?+?, ?3
=−?−?, and ?4=?−?.

Use the method of Lagrange multipliers to solve this exercise. I
want to fence in a rectangular vegetable patch. The fencing for the
east and west sides costs $4 per foot, and the fencing for the
north and south sides costs only $2 per foot. I have a budget of
$96 for the project.
What is the largest area I can enclose? ft2

Question B:Consider the integral of sin(x) * cos(x) dx.
i) Do it using integration by parts; you might need the “break
out of the loop” trick. I would do u=sin(x), dv=cos(x)dx
ii) Do it using u-substitution. I would do u=cos(x)
iii) Do it using the identity sin(x)*cos(x)=0.5*sin(2x)
iv) Explain how your results in parts i,ii,iii relate to each
other.

Use the method of Lagrange multipliers to solve this
exercise.
I want to fence in a rectangular vegetable patch. The fencing
for the east and west sides costs $6 per foot, and the fencing for
the north and south sides costs only $3 per foot. I have a budget
of $120 for the project. What is the largest area I can
enclose?
Please find answer (show steps) and will rate!

I have the correct answer but I want to know how to solve it
step by step, please help. Thanks

1) What is the obtained F-ratio? (correct answer: 0.474)
2) What can you conclude with ANOVA? (correct answer: Fail to
reject the null, p> 0.01; Type II error is possible)
3) What is the standard deviation of Y for the sample? (correct...

Using Matlab, solve the following ODE using Euler's
method...
I have to perform solve the ODE with both step sizes and plot
both on the same graph.
y'=1/y, Initial Condition y(0)=1. step size = 0.1 and 0.01
The interval is from 0 to 1.
UPDATE: I actually figured it out myself! THANKS
