0.1*0.1=0.01 can someone explain this to me please.

0.1*0.1=0.01 can someone explain this to me please. Im really confused although it is something really basic ;S-0.1 = 1/10 => 1/10 x 1/10 = 1/100 = 0.01 :)>-Well, have you done indices? As in 10^2

Math Help! Pre-Calc Question.

A piece of wire is 8 inches long. The wire is cut into two pieces and then each piece is bent into a square. Express the sum of the areas of these squares, A as a function of the length of th cut, x.

Functions finding the domains

a) x+1 / √ x^2-4 b) 1/√ x^2-1 thank youuuu-If you think of a function as a recipe and the variable as the ingredient, then the domain is the list of ALL the ingredients you could use. More formally

How do you find the limit of [ (√x) - (√sin(x)) ] / x^(5/2) as x goes to 0

lim(x-->0)[ √x - √sin(x) ] / x^(5/2)= =lim(x-->0)[ √x - √sin(x) ] / [x²√x]= =lim(x-->0)[ 1 - √(sin(x)/x) ] / x²= =lim(x-->0)[ 1 - √(sin(x)/x) ][ 1 + √(sin(x)/x) ] / (x²[ 1 + √(sin(x)/x) ])= =lim(x-->0

Mathematics (Multivariable Calculus: Absolute & Local Max Min)

Consider the function: g(x,y) = 3xe^y - x^3 - e^3y There is exactly one critical point. This function has a local max. The local max is NOT the absolute max. Why is the above the case? How is the

Can someone find the derivative of this

v(t) = 12t^2 -10t + 6 - (pisin(pit))for any time t-v(t) = 12t² - 10t + 6 - π sin ( πt ) v(t) = 12( 2t ) - 10( 1 ) + ( 0 ) - π· cos ( πt )· π v(t) = 24t - 10 - π².cos πt .............................

5 ( 4 + 2X) - ( 8X - 12)= 68

distribute 20 + 10x - 8x + 12 = 68 move the variables and constants together 10x - 8x = 68 - 20 - 12 2x = 36 divide x = 18-20+10X-8X-12=68 8+2x=68 x = 30You first multiply the 5 times the 4 and

Can someone help with Statistics Problem

Scores on a certain nationwide college entrance examination follow a normal distribution with a mean of 550 and a standard deviation of 100. Find the probability that a student will score: (a) Over 6

How do you simplify cos(29π/6)

Can you explain to me how this works?-cosine is the measure of the x coordinate of a point as it rotates around a circle.Naturally, the point travels around in a circle and keeps going in circles once

Solve for y: 8+3/y-2=-3/y-1

the problem is: 8+3/y-2=-3/y-1I got y=1/4,1/2 but Im not too sure if it is correct. 5 stars best answer thank you everyone-multiply by y 8y + 3 - 2y = - 3 - y 7y = - 6 y = - 6/7-Plug in your answ

Solve the logarithmic equation

log(3x)=log(13)+log(x−8) If you could show me the steps it would be helpful -log(a) + log(b) = log(ab) log(3x) = log[13(x – 8)] 3x = 13x – 104 104 = 10x x = 52/5-or u could do your own hw

Is it worth studying for this maths test

I am terrible at maths. I am in year 10 and am one of the worst in the class. There is one guy in my class who is a complete maths nerd and he even joins maths competitions and wins awards and stuff.

Taylor series for f(x)=ln(1+4x) centered about x=0

Start with the geometric series 1/(1 - t) = Σ(n=0 to ∞) t^n. Let t = -x: 1/(1 + x) = Σ(n=0 to ∞) (-1)^n x^n. Integrate both sides from 0 to t: ln(1 + t) = Σ(n=0 to ∞) (-1)^n t^(n+1)/(n+1). Replace

Anyone Know System of Equations

I am going to be honest...I am the worst at this, lol. I know you guys hate answering more than like 2 questions, but I promise, I need help! I do not like cheating, so if you just want to show me in

Okay.. If P(A) = .02, and P(B) =.03.. Help me!

If P(A) = .02, and P(B) =.03 And P(A and B) = 0 What is P(A or B)? How do I do this? Totally lost @_@ Thanks-When P(A and B) = 0, the events A and B are said to beMUTUALLY EXCLUSIVE. When the event
