Rationalising SURDS, need help

Can you tell me the answer to 5/(divide)3 square-rooted AND tell me HOW you worked it out step-by-step thnks-Is it 5/√3 ? multiply by √3 and divide by √3 5/√3 = 5√3/√3√3 = 5√3/3 = 5/3 √3 ----

M=2; (-3, 4) slope equation help pls???URGENT!!!!

Please help me thx! OK i have a question about the slope equation which is y=mx+b im having really much trouble with these stupid questions, im suppose to figure out what is b in the slope equation!!!

Finding the product of these equations->

I need help getting the solutions of these equations. 5jk(k-2j) (2a^3-a+3)(a^2+3a-5) (y-5)^2-There are not equations because they do not have an equals sign.

Algebra problem help!!!!!

I have to simplify (a^2-b^2) over (-2a^2-ab+b^2). Please help. Im confused.-(a^2-b^2) / (-2a^2-ab+b^2) factor fully. (a-b)(a+b) / -(2a^2 +ab -b^2) (a-b)(a+b) / -(2a-b)(a+b) NOTE that (a+b) / (a+

Normally Distributed Data

Given normally distributed data, μ=65, σ=8, how do I find the answer to: P(70 ≤ x ≤ 80) P(x1 ≤ x ≤ x2) = 0.2434 P(x ≥ x1) = 0.7157-μ = 65 σ = 8 standardize x to z = (x - μ) / σ P( 70 P( 0.625 (Fro

Need help on SURDS - expanding brackets

what is the answers to: (1 - 3 square-rooted ) (2 + 3 square-rooted) AND can you please tell me HOW you worked it out step-by-step-(1 - √3)(2 + √3) Multiply everything in the first bracket by eve

How to identify the coordinates of all removable discontinuities for f(x)=x^2-49/x-7

--- Be very careful when you write equations.In a book for example this expression might have been written like this: x^2-49 ---------x - 7 When you type that you have to add parentheses to prese

Integrate √(4+x^2)/x dx

∫√(4 + x²)/x dx Let x = 2*tan(t) ∫√(4 + 4*tan²(t))*2sec²(t) dt/(2*tan(t)) 2*∫sec^3(t)/tan(t) dt 2*∫(sec(t) + sec(t)*tan²(t))/tan(t) dt 2*∫csc(t) dt + 2sec(t) + C -2*ln|csc(t) + cot(t)| + 2*sec(t

Convergent or divergent sequence

Hello, I have 3 questions here, hopefully someone can please help me to check on their convergence and limit. 1. sequence = (ln n / ln 2n)the limit I calculated is 1. therefore, convergent. 2. seque

Need help with a quick math problem?: (b - 2/3)^2 + 4/9 = 0

Again the problem is (b - 2/3)^2 or to the second power + 4/9 = 0 and if you can explain to me how to do this problem thank you very much :)-Okay, first you need to distribute the ^2 into the parenth

Math Help: Rounding Decimals related question.

Note: Please remember, I do not want the answer to the question! I just want to know the process of which to work the problem! Q: A 3/16inch drill bit has a diameter of .1875 inches. What is the size

Find the x-intercepts of the graph of the equation.Please help thanks(:

y=x^2-3x+2-y=x^2-3x+2 factor the quadratic x^2-3x+2 (x-2)(x-1) set these two to zero (x-2)=0, (x-1)=0 solve for xs 1st gives x=2, 2nd gives x=1, so these are the x-intercepts, x=2, x=1-you can factor

Can someone help me solve this math problem

Find the polynomial for the perimeter and for the area of a rectangle Measurements: n+8; n What is the perimeter and the area-The perimeter would be 2(n+8) + 2n = 4n + 16 The area would be n(n+8) whi

Express the region inside the leaf of the rose r=2sin2θ in the first quadrant as an iterated integral over R

The leaf in the first quadrant touches r = 0 when 2 sin(2θ) = 0 ==> 2θ = 0, π ==> θ = 0, π/2. Hence, the area of this leaf equals ∫∫ 1 dA = ∫(θ = 0 to π/2) ∫(r = 0 to 2 sin(2θ)) 1 * (r dr dθ). I hop

Limit function.........................

lim x→0 ((18x - 2sin 5x)/(tan10x - 3sin4x) ) lim x→¼π ( 8cosx - 8sinx )/(x - π/4)-Using Lhôpitals rule We have limit (f(x) / g(x)) as x tends to c If f and g tend to 0 and the derivative of them ex
