It means I ate some pie. It means that because sqrt(-1) is i. 2^3 is 8 which is read as ate. Σ means sum which is read as some. And obviously π is pi which is read as pie.
Volume of a cone is given by pi r^2 h/3
V = pi x 15^2 x 67/3 = 15786.5 in^3
$1.06/in^3 x 15786.5 in^3 = $ 16,733.69
A-h-h-h-h THAT's what those little arcs symbolize ! Learned something today ! Thanx Chris....
A dilation is an isometry if (r,t) --> (kr,t), where k > 1.
T: x --> u
x = (x,y) = (rcost, rsint)
u = (u,v) = (krcost, krsint) = k(rcost, rsint) = kx
T is an isometry if u/kr = x/r, which is in fact the case here in this question.
Well i didn't make this exercise, i just have to solve it so i don't know if it's wrong or not. What i do know is i have written it correctly.
It is 7. 5+2=7. :)
Thanks so much!
3 is based on Euclid's Elements...a bisected apex angle proportions the sides of the triangle thusly :
[2x - 1] / 9 = 3x / 15 cross-multiply
15 [2x - 1 ] = 9 * 3x
30x - 15 = 27x
3x = 15
x = 5
10n ( 4n+5) - 2 =
40n^2 + 50n - 2 Is THIS what you meant?
#2 use ratios since they are similar 21 is to 14 as x is to 10
21/14 = x/10 x = 210/14 = 15= AB
#3 if it is a right triangle....again Pythagorean Theorem
2x-1 + 3x = sqrt(9^2 + 15^2)
5x -1 = 17.49
5x = 18.49
x = 3.699
Thanks, EP....!!!!
a is a length not an angle measure use Pythagorean theorem
sqrt(25^2 - 20^2) = a
Here ya go..... was playing around with some online plotters and drew this one....
Get back to work.
Thank you so much both of you!
Footballgirl...I can't get the pic to upload....but it's a rhombus.....
I'll see if the image thingy works later....!!!!!
In physics, this scenario describes IMPULSE ... F x t also known as the change in momentum...(final momentum = 0)
Momentum = m x v
= .1 mg x 1kg/1000mg x 3 x 10^3 m/s = .3 kg-m/s = .3 N-s
F x t = .3 n-s
F = .3 N-s / (6x 10^-8 s) = .05 x 10^8 N = 5 x 10^6 N BANG ! You just spent $ 50,000.
Sorry did the points wrong-- w(0,1), x(4,2), y(3,-2), z(-1,-3)
21 ...
The answer is 7.
I would say one left and three right.
W(0 , 1) , X(4 , 2) ,Y( 3 , 2) , Z(-1 , -3)
Are you sure that you have the correct points???
This is not a parallelogram......
False
1 left 2 middle and 2 right
