pi is the ratio between the circumference of a circle and its diameter
sine is the ratio between the side opposite an angle of a right triangle and its hypotenuse
both depend on the IDEA of the rati
BEST ANSWER-multiply out the brackets
x^2+3x-x-3
x^2+2x-3
then take 4 to the other side so its
x^2+2x-3-4x
x^2-2x-3=0
(equate to 0 )
(x-3)(x+1)=0
x=3 or x=-1-The Captain and Watz are correct.

Weve got [integral]f(u(x)) u(x) dx -> [integral]f(u) du, u = tan(x)
So... how come the answer is not (Tan[x]^2)/2-the answer is(Tan[x])^2 /2 + C-∫tan(x)*sec²(x) dx = tan²(x)/2 + C
Your answer is cor
How would you multiply 4√3 by 4? And also, how would you ADD 4√3 and 4? Thanks!-4√3 x 4
is the same as
4√3 x 4√1
because the √1 = 1 in itself, so were not changing the euation at all.
multiply
1)
0.7(3x+2)=1.1-(x+3)
x=?
2)
a+(a-3)=(a+5)-(a+2)
a=?
3) A 300 m wire is cut into 3 pieces. The second piece is 3 times as long as the first. The third piece is 2 times as long as the second. How lo
1) what is the value of W in the equation
3/4w+8=1/3w-7
Thank you :)-Assuming you mean (3/4)w + 8 = (1/3)w – 7
Subtract 8 from both sides and subtract (1/3)w from both sides:
(3/4)w – (1/3)w = –7 –
Hi
anyone can explain me please how to simplify thesesurds -
Plscheck theJpeg i have uploaded herehttp://freeimagehosting.net/image.php?2711d7e5ab.jpg
as i canttypethe square root sign (ctrl 252!
I have a general question about simplifying polynomials. Would x^2+3x+11 be the simplest form or would it be x(x+3)+11. is this going to far, or is it really needed? if the polynomial is prime do i ha
let f( x , y) = 7x - y / x + 8y
∂f./ ∂.x = A(x+8y) - B(7x - y) / (x+8y)^2
A=
B=
C=
Thank you-You must mean f(x, y) = (7x –y )/ (x + 8y).
Taking partials wrt x just says to treat y like is was a
1. graph each function just tell the coordinates
y=1/2x^2-1
2. y=-2x^2+3
3. solve each equation by finding square roots.if equation has no real solution, write no solution. if necessary round to th
A square is circumscribed about a circle. What is the ratio of the area of the circle to the are of the square?
please explain
Thank You!-Lets say the sides of the square is 1 cm, then the diameter
A motorcycle has four gears. The maximum speed in bottom gear is 40 km h^-1 and the maximum sped in top gear is 120kmh^-1. Given that the maximum speeds in each successive gear form a geometric progre
u cannot factor this! what u can do is to find the value of x which is different
Hope this Helps!-this equation is quite impossible to solve it...
I used a calculator and the answer is
x = 11.39150
Consider x^2+y^2=r^2 and y=mx + b. find the value(s) of b in terms of r and m so that the graphs of the two given equations will intersect at one and only one point.
Ive thought of b = +Sqrt(r^2+m^2)
