In Triangle XYZ angle x = 42, angle Y = 58 and z = 10. what is the measure of side x

i am going to fail this math takehome test.-Note that, since X, Y, and Z are the three angles of a triangle, then: X + Y + Z = 180° ==> Z = 180° - X - Y. Thus, Z = 180° - 42° - 58° = 80°. Then, usin

Whats the difference between a real number and a rational number

i didnt get it :(-natural numbers are all positive numbers without a comma like 1,2,3,4,5 and so on. integral numbers (integers) are numbers including the natural numbers, but also the negative numb

Algebra question....

Go to the link to view the question http://i55.tinypic.com/sz9yds.png-(1/7)(3^6) 729/7-Okay. We start out with: F(X) = 1/7 x 3^X. Then they tell us that F(6). This isnt an equation; we dont have to s

An equation of the line that passes through point (0,3) and whose slope is -2 is? Answer and explain

(a) y=-2x+3 (b) y=-2x-3 (c) y=2x+3 (d) y=2x-3 Thanks.-Recall slope-intercept form. y=mx+b, b is the y-intercept (when x=0), and m is the slope. You know the slope is -2, m=-2, and the intercept is 3

Please help, how to solve: log4(x+1)=log4(4x-5)

The 4s after log is supposed to be smaller. Base, I think it is called.-log₄(x + 1) = log₄(4x - 5) implies that x + 1 = 4x - 5 Therefore x = 2-You take the opposite of log base 4 on each side: 4^(Log4

What would you like to ask?what values of p the series ∑ln(n)/n^p is convergent

I get stuck at lim t--> infinity [ln(n)t^1-p / 1-p -t^1-p/ (1-p)^2] from 1 to t ........ I took the integral for lnn/n^p and set the interval [1, infinity) t substitutes for infinity. I dont know what

Parabola equation help

How do I solve for y? It has to be able to go into a graphing calculator..... y^2+16y = -4.5x-23.5 The original equation I had was (y+8)^2 = -4.5(x-9) if that helps at all. Thanks!-using your origin

Would a 10% chance be equal to a 1 in 10 chance

Like, if something with a 10% chance happened 10 times, would it most likely happen once? same with 5% chance happening 1 in 20?-A 10% chance is equal to a 1 in 10 chance.The rest is incorrect.Ill exp

Tough Integral problem

how to integrate this? integratal: x/((x-1)^2*(x^2+2x+2))-x /(x - 1)^2* (x^2 + 2x + 2) first split into partial fractions x /(x - 1)^2* (x^2 + 2x + 2) = A/(x - 1) + B/(x-1)^2 + (Cx + D)/(x^2 + 2x +

Prove the identity sin^2(x)-cos^2(x) = 2sin^2(x)-1

Since sin^2(x) + cos^2(x) = 1, we see that: cos^2(x) = 1 - sin^2(x). Substituting this in for cos^2(x) gives: LHS = sin^2(x) - cos^2(x) = sin^2(x) - [1 - sin^2(x)] = sin^2(x) - 1 + sin^2(x), by distr

Help: find the inverse

Please show work/explanation. Obnoxious and irrelevant answers will be reported. f(x)=ln(x+3)-2-You switch the x and y variables and then solve for the new y. f(x) = ln(x + 3) - 2 y = ln(x + 3) - 2
