Operations with Radical Expressions (Algebra 1) problem

This is something I got wrong on my homework- what is 3sqrt(50)+sqrt(8). Evidently its 17sqrt(2), but thats far off from what I got..-Ok here goes 3sqrt(50)+sqrt(8) now we can also write as 3sqrt(

How do you factor quadratic equations

The problem that Im having the most difficulty with is x²+7x+10=0.-(x + 5)(x +2) You begin by making two open sets of parenthesis: ()() Obviously, since the first thing in the problem is X^2 then yo

Math Help. PLEASE HELP!

Really hard math question please helpp

k = the square root of 1-2p^2/5p make p the subject PLEASE SHOW ALL WORKING! thank you +10 pts-making p the subject merely means to put the equation in terms of p , if you took grade 9 math you would

Select the type of curve described by the polar equation tan θ = 2.

Circle Ellipse Line Point Spiral-Note that, since tanθ = sinθ/cosθ, we see that: tanθ = 2 ==> sinθ/cosθ = 2 ==> sinθ = 2cosθ. Then, multiplying both sides by r gives: r*sinθ = 2r*cosθ. Then, using t

What's the answer to this question

write an equation for the line that is parallel to x=3 and passes through point (-4,3). explain how you did it-The line x = 3 is a vertical line parallel to the Y-axis on the Cartesian plane. It passe

Logarithm inverses... confusion!

I am having trouble understanding this.Probably because the distance course Im doing kind of jumps steps and doesnt explain. I am just kind of stuck trying to inverse log functions. It gives me: y

Determine the value of c thats make the equation a perfect square y=x²+8x+c

Thanks-16, x+4 ^ 2 When you start with x^2, its simply a matter of halving the 8 from 8x and then squaring that. _-(x+a)(x+a) = x^2 + 8x + c x^2 + 2ax + a^2 = x^2 + 8x + c so 2a = 8 or a = 4 and c =

Anyone know how to solve this Polar Equation

I need to replace this Polar equation with equivalent Cartesian equations. r^2+2r^2cosxsinx=1.-r^2 = x^2 + y^2 sin(t) = y/r cos(t) = x/r r^2 + 2*r^2*cos(x)*sin(x) = 1 r^2(1 + 2*cos(x)*sin(x)) = 1 (x^

Find the point on the curve closest to the point (1,3)

How is the proper fraction 3 and 184/1000 simply reduced to 3 and 23/124

It actually simplify to 3 23/125 The rule is: As long we multiply the same number to the denominator and the numerator, the value of the fraction remains the same. For example 2 / 5 = 4 / 10, beca
