You should calculate fully and try to be a little more understanble

Sol: HCF of 180, 252 and 324: 324 = 1 x 180 + 144 180 = 1 x 144 + 36 144 = 4 x 36 + 0 So, HCF of 324 and 180 = 36 HCF of 252 and 36: 252 = 7 x 36 + 0 So, HCF of 252 and 36 is 36. Hence, the HCF of 180, 252 and 324 is 36.

a) 3x(3x-1) b) (2x-3)(2x+3)
This equation is derived from the following: at maximum height the velocity is zero. y(current height)= y0 (initial height)+v0t+.5at^2 take the derivative 32t-v0=0 so vo=32t Plug this in for the v0 value 16t2 − (32t)t + h = 0 h=49ft -16t^2+49=0 Solve for
find the derivative: f'= 15x^14 this function is always positive (graph if you don't believe me) because any number to an even power must be 0 or greater. thus since the derivative is always positive, the graph of f (x) is always increasing :P
plug in 1 for n for the first term. plug in 2 for second term and so aon until the sixth term ex:(-3)n (-3)1=-3 (-3)2= -6 etc... :P
plug in the value for x and solve 3(2)-10 6-10 =-4 capish?
Draw graph of y= x^(1/2) to help you understand solution. Rotation about y-axis means that the radius of the solid (length being swung around the axis is the x-value). it helps to solve for x-value rather than try to substitute everything. x=y^2 where y>0
Graph it if you don't understand my solution: Linear equations follow the format y=mx+b where m is the slope and b is the y-intercept. let y= fees and x=number of credits now calculate slope (change in y/change in x) m=(2600-2000)/(6-3)= 200 y=200x+b Plug
a) illogical nonidentity because 4 does not equal 5 b) testable statement. i don't know your definition of logical statement and can't be of much more help here 3) false obviously d) logical statement due to commutative prop of addition
for the first one I assume they want you to factor out ¡ñ 30 and add 801+4 for the second, I assume they want you to first factor out ¡ñ 20 then do the combination--not 100% sure.
x intercepts...think of the graph. the line crosses the x-axis when y=0. so set y=0 0=(3x+2)(x+2) 0=(x+2) or 0=(3x+2) Solve to get -2 and -2/3 As for axis of symmetry and vertex...you can use vertex form or remember that (-b/2a) in ax^2 +bx+c will give you
lim (x->0) x^4 cos 2/x= =lim (x->0) x^4 * lim (x>0) cos 2/x = 0 * lim (x>0) cos 2/x cos (a) will always be between -1 and 1. but this is irrelevant since x^4 is 0 at x=0, and anything multiplied by 0 is 0 :P
it is the length of the circle's perimeter the formula for cicumference is 2 pi r. pi is a contstant that goes on forever (3.1425....) and r is the length of the radius
Bring constant to other side: y-81=9x^2+72x Make constant in front of x^2 term one: (y-81)/9=x^2+8x (y/9)-9=x^2+8x complete the square...(x+a)^2= x^2+2abx+a^2. x^2=x^2 so 8x=2ax= so a=4 4^2=a^2=16 The equation you want to create is (x+4)^2= x^2+8x+16
Ok, but thanks for the link.
