How to do this math problem

Solve: 3^(2y-4)=9^(3y+2) It is confusing for me when the variables are in the exponents-first, break the 9 down. you get 3^2, right? now since the bases are equal (3 and 3), you can set the exponents

(x^2)/(x-5)^3 find limit 5+

Lt x ---> 5, x^2/(x-5)^3 = Infinity >==============

Math study guide! these are the only problems left i need help with please!!!!!

For questions 1–6 identify each sequence as arithmetic or geometric. Then find the common difference or common ratio. 1.13, 19, 25, 31, ... 2.16, 24, 36, 54, ... 3.4, 14, 24, 34, ... 4.1, 4, 16, 6

Quadratic equations (help please)

how can i solve this? x^2 + x = -2 thankx-to make our job easier lets take the -2 from right hand side(RHS) to the left hand side(LHS) to leave 0 in RHS we get--- x^2+x+2=0 to solve for x we need t

6÷2(1+2)=? 9 or 1.....

I thought it was 1 because of PEMDAS but I feel like Im wrong actually.Is it 9 or 1?-Last time I post this I will break this down as simply as possible and end this debate as approx. 10 students hav

How do I compute this ratio series test

infΣn=1 ( (3n)!/(n!)^3)) Please show your working, Im finding this one tough. Thanks James-r = lim(n→∞) |a(n+1) / a(n)| = lim(n→∞) |[(3(n+1))! / ((n+1)!)^3] / [(3n)! / (n!)^3]| = lim(n→∞) [(3n+3)!

How would you solve for the sum of a series from n=1 to infinity of (5^nx^(2n))/(6^(n+1))

I have an exam tomorrow and I am not quite sure how to solve this type of problem. An explanation would be really helpful. Thank you!-Note that this may be rewritten as Σ(n=0 to ∞) (1/6) * (5x^2/6)^n

Prove that T(a,b) is a permutation by directly computing T(a,b) ° T(a,b).

Let X be any set and fix a,b be an element of X. Define T(a,b):X to X by T(a,b) = x if x is not an element of {a,b}b if x = aa if x = b Prove that T(a,b) is a permutation by directly computing T(a,b

For the function find the values of x that satisfy the given condition: Solve g(x) > 0 if g(x) = 2x^2 + x - 10

To make learning math a bit easier for you, Dr. Pan (TucsonMathDoc) has recorded a YouTube video to help visually answer your question. Please comment on YouTube or Y!A and let her know if it helped.

Integrate by part please show your work thanks

please do step by step coz im new for this ∫ t²cos t dt-cos t = (sin t)so to do integration by parts we can move the derivative from the cos to the t^2 i.e. to end up with an integrand like 2tsin t a

Can someone help me solving the following problem

Let V(t) = 2ln(t). (i) Find the slope of the function at t = 1. Interpret your answer. (ii) Find the equation of the tangent at t = 1.-For this, recall that the derivative of log(t) (ln(t) ) is 1/t

Which type of graph would be better for this situation

To show the number of students and what grade their in. Would you use a circle chart or bar graph?-Number → Bar Graph Percentage → Circle Chart

I'm 18 and still don't have my multiplication tables memorized is this a bad thing

i dont use it that often lol-I wouldnt worry too much about it. Youre probably not alone. And its not like youre guna get quized on it anyways.-Having your tables not memorized isnt a bad thing, I don

Can someone help with this easy math question

The time spent studying and the scores received can best be presented in what type of display? A. a circle graph B. a double-bar graph C. a bar graph D. a line graph EASY FOR U MATH GENIOUS, HARD FOR

For the function find the values of x that satisfy the given condition: Solve f(x) < 0 if f(x) = x^2 - 5x

Clearly , x cannot be 0, since then f(x) cannot be Hence, you can divide f(x) by x to see that f(x) = x - 5. So, f(x) -factorising, x(x-5) 0 but so, 0
