Maths Question- Please Help ASAP!!!

How do you find the gradient of the tangent to the curve y= x^2+ 5x+ 6 at the point (1,12)?-Differentiate the given curve: so, dy/dx = 2x + 5 Now since the point (1,12) its x co-ord is 1 So put this

What are the factors of 34

34 is a composite number; it has factors other than 1 and itself. It is not a prime number. The 4 factors of 34 are 1, 2, 17, and 34. The factor pairs of 34 are 1 x 34 and 2 x 17. The proper fac

Would the equation y=10 have a horizontal asymptote at 10

No, the equation is represented by a horizontal line through 10 on the y-axis.An asymptote is a line the graph approaches but never reaches.-NO , because for any x going to infinity , f(x) doesn´t ten

Help simplfying a trig identity

sin(pi/4+x)-cos(pi/4+x) So far I have: =(sinpi/4)(cosx)-(cospi/4)(cosx)=(sqrt2/2)(cosx)-(sqrt2/2)(cosx) ...and now Im stuck :/ The answer is suppossed to be sqrt2sinx-I can see your problem already...

Calculus problem the Integral of 1/x(sqrt(1-(lnx)^2) dx

Having some issues figuring out how to do this problem, it is 1 over x times the square root of one minus ln x squared all multiplied by dx.-Use the substitution u = ln x, du = (1/x) dx. So, ∫ dx / [

Calculus question......please help..........10 pts

ifx^2 + xy + 3y^2 =1 prove that (x+6y)^3 y +22 = 0 , here y means double differentiation of yw.r.t.x pleasegive the steps too.-x² + xy + 3y² = 1 Differentiate. 2x + y + xy + 6yy = 0 (x + 6y)y = -(2x

I need help simplifying/factoring these expressions

10 pts best answer. Please help. 1. Simplify: x(x-1)(x+2) 2. Factor: 2x+12x^3 3. Factor: 5ab – 15abc 4. Factor: 2x^2+ 7x - 4 5. Factor: 9x^2–36-x(x-1)(x+2)=x(x²+x-2)=x³+x²-2x 2x+12x^3=2x(1+6x²)

Finding the kernel and image

Let A= [1 1 1 1] [0 1 2 3] [0 2 -1 5] [0 3 -4 7] Find bases for ker(A) and Im(A). Are ker(A) and im(A) isomorphic? Why or why not?-First, row reduce A: [100-9/5] [01013/5] [0011/5] [0000]. Note we ha

Probability - P(A/B) and P(intersect) is given, find P(B')

P(A/B) = 0.75 P(A-intersect-B) = 0.6 Find P(B)-0.75=0.6/p(b) 0.6/0.75=p(b)=0.8 1-0.8=0.2=p(b)

How do you solve this with subsitution? (alg. 1)

How do I solve this system of equations with substituion? 9x+10y=90 2x-8y=16 And can you please explain how to do it? I dont really get it Thx.-9x+10y=90 2x-8y=16 9*x + 10*y = 90 x - 4*y = 8 x
