Collecting Like Terms Question

A = P + Prt Solve for P It would go, according to what I see (1):A = P + Prt (2):A = P(1+rt) And thats where I get lost. Wouldnt combining P and P be 2P at that point, so where did the second P go a

Does the sequence have a convergent subsequence

If xn=(sin(n), cos(n), 1+(-1)^n), does the sequence {xn} in R^3 have a convergent subsequence? I think you just have to show that it follows the Bolzano-Weierstrass Theorem but Im not sure... Help?

Algebra Trig word problem!

I am confused on 2 problems! 1. An automoblie manufactur can provide no more than 95 cubic feet of passenger space and luggage space for one line of automoblies. The amount of passenger space must be

Use the inner product...

Use the inner product = f(−2)g(−2) + f(0)g(0) + f(2)g(2) in P2 to find the orthogonal projection of f(x) = 4x^2 + 4x + 1 onto the line L spanned by g(x) = 2x^2 − 5x + 8. proj_L(f) = ? I found the in

How do i factor this? please help :)

x^2+2x+5-x^2+2x+5 x(x+2)+5-You can simplify that thinking like this: x^2+2x+c+d, when c+d = 5 solving the equation x^2+2x+c=0 for delta(polynomial discriminant)=0, you find the root=-1 for c=1 so n

How do i factor this completely

6(3x+2)^2 - 3(3x+2) - 8-6(3x +2)^2 - 3(3x +2) - 8 = = 6*(3*x +2)^2 -3*(3*x +2) -8 = 54*x^2 +63*x +10 = 54*(x +0.977)*(x +0.19)-this is not possible.-This is not factorable.-not factorable none of the

How do you find x if the square root of x plus the square root of (x minus 20) equals 10

√x + √(x - 20) = 10 Squaring both sides: x + 2√(x² - 20x) + x - 20 = 100 2x + 2√(x² - 20x) = 120 √(x² - 20x) = 60 - x Squaring again: x² - 20x = 3600 - 120x + x² 100x = 3600 x = 36 Hey Captai

AP Calculus Question

All the question says is solve for x: 3 - x^2 = 2^x (the 2 is an exponent of x and the x is an exponent of 2) I wasnt sure if you would start by logging both sides of the equation? If you could show y

How to solve these using the factor/remainder theorem

1. Factorise the following. (a) x^4 - a^4 (b) x^5 + a^5-(a) a^4 - b^4 = (a^2 + b^2)(a^2 - b^2) = (a2 + b^2)(a + b)(a - b) (b) x^5 + a^5 = (x + a)(x^4 - x^3a + x^2a^2 - xa^3 + a^4)
