Ive only learned how to solve first order linear differential equations, but this was on my homework.
y = 10 - 2y^2
thanks!-y = 10 - 2y^2
dy/dx = 2 * (5 - y^2)
dy / (5 - y^2) = 2 * dx
Let y = sqrt(
1. Simplify the algebraic expression by combining similar terms. (Objective 3)
5(x − 1.2) − 4(x − 2.1) − 3(x + 1.9)
2. Answer the question with an algebraic expression.
The width of a rectangle is
I have the answer but when factoring I dont get that answer. whats wrong ??
2x^3 + 4x^2- 16x
=a+2 b+4 c=16
ac=2(-16)= -32
the two factors of -32 : -8 & 4 but that doesnt add up to 4.
anyways so
= 2x^
I dont know the calculator you are using, but you would want to graph y = x^2 + 6x - 16 and find the x-intercepts.
Your solution are the values of x for which the function is positive, that is, above
A rubber ball as dropped from the top of a wall 16 ft High. Each time it hits the ground it bounces half as high as its previous high point. If the ball is caught just as it bounces 1 foot High, how f
x*(dv/dx) = -2v, using substitution, v = y/x. Any ideas on how to work this? Im confused. Thank you.-This is exact:
x dy/dx + y = (d/dx)(xy) = 0.
Integrating both sides yields xy = C.

what are the steps to figure this out?
5(2X-3) - 3(X-4);X= 1/4-If Im interpreting the question correctly, just replace every occurence of X in the expression with 1/4 and do the arithmetic.
5(2x - 3)
Using only the first nine digits (1-9) in order, make an equation that is equal to 100?-100 = 123456789
100 = (1 + 2 + 3 + 4 + 5 + 6 + 7) + (8 * 9)-Math is NOT hard.You are telling your brain that and

A lottery claims that 10% of tickets win a prize. How many tickets should you buy to be 50% sure of winning a prize?
This question is of binomial distribution/bernoulli trials. Can anyone help? I tho
R = [cosθ-sinθsinθcosθ]-(This is the rotation matrix which rotates a vector by an angle θ counter clockwise.)
det(R) = cos^2 θ + sin^2 θ = 1==> R is nonsingular.
R^-1 = [cosθ sinθ | -sinθ cosθ]
