I have the answers But i just needed to know how to get it by steps like show work? plus its not homework its just work that my teacher gave me but she wouldnt show me how it was misunderstanding actu

How many combinations are possible

Professor Easys final examination has 8 true-false questions followed by 3 multiple-choice questions. In each of the multiple-choice questions, you must select the correct answer from a list of 5. How

Verify (1+sin/cos) + (cos/1+sin) = 2sec

Will assume that question is INCORRECT and SHOULD read as :- ( 1 + sin Ө ) / cos Ө+ cos Ө / ( 1 + sin Ө) ( 1 + sin Ө ) ( 1 + sin Ө ) + cos ² Ө --------------------------------------… cos Ө ( 1 + sin

Multiple Choice. Name the property used to make the conclusion

1.) If x + 7 = 23, then x = 16 2.) If 4x = 40, then x = 10 3.) If x = 7 and y = 7, then x = y 4.) If 4x = 28, then 28 = 4x 5.) If x - 24 = 25, then x = 49 a. addition property of equality b. sub

What is the integral of (4+4x^2+(1/x^2))^(1/2)

Its been too long since I took calculus... Thanks-(x sqrt(4 x^2+1/x^2+4) (x^2+log(x)))/(2 x^2+1) + C-Vico the whole thing is supposed to be square-rooted. You didnt clean up, you destroyed it.Report A

Simplifying the expression

X/ (X - 1)-( X - 1)/ (X + 1 ) i canceled the (X-1) and then subtracted and i got an awnser of X-1 / X+1 , is that correct?-(x / (x - 1)) - ((x - 1) / (x + 1)) = ((x(x + 1)) / (x - 1)(x + 1)) - ((x - 1

Dividing Trionomials by a Binomial

I am stuck on this problem for my homework assignment: 2x^2 + 7x + 3/2x + 3 Do i factor the trinomalfirst? im not sure. Thanks in advance.-I think it should be (2x^2 + 7x + 3) / (2x + 3), not just2

What is the probability of selecting a red and a white and blue

A box contains 3 red marbles, 6 blue marbles, and 1 white marble. The marbles are selected at random, one at a time, and are not replaced. What is the probability of selecting a red and a white and bl

My final is worth 20% of my grade if I get a 70 on my final I get an 80 grade.What if i get a 60

Let x be the rest of your average. x(80%) + 70(20%) = 80 ==> x = (80 - 0.2(70))/0.8 = 82.5. If you get a 60, youll have 82.5(80%) + 60(20%) = 78. That is a final grade of 78.-My final is worth

Differentiate f(x) = 4x(x^2 + 1)^3

Using the product rule and chain rule I can get it to: f(x) = 4x * 3(x^2 + 1)^2 * 2x + 4(x^2 + 1)^3 but then my solution guide says: f(x) = 4(x^2 + 1)^2 * (7x^2 + 1)as the final step. How does one a

Solve each of the quadratic equations for their exact values by using the square root principle

a) 4x^2 -13 =0 b) -2(6x-3)^2 -12= - 48-a) 4x^2 - 13 = 0 x^2 = 13/4 x = ±√(13) / 2 b) -2(6x - 3)^2 - 12 = -48 (6x - 3)^2 = 18 6x - 3 = ±3√(2) x = (1 ± √(2)) / 2 ♣♦

Integral Question help please

Suppose that f(1)=-1, f(4)=-9, f (1)=-3, f (4)=-7, and f is continuous.Could you find the value of integral 1 to 4 (x f (x))dx. ?-d{ xf(x) } / dx = f(x) + xf(x) ∴ ∫ d{ xf(x) }, [x=1,4] = ∫ f(x)dx, [

How to solve (2x5)x 5-(50-15)

(2x5)x 5-(50-15)is it 300? 10 * 5-(35) 10* -30????-Always do sums in brackets first so, 2x5=10 50-15=35 So...10x5=50 50-35=15 :) Hope i helped-Do you remember BIDMAS which is brackets, indices, divi
