What is 21+49 Diveded by 7+1
USE PEMDAS AND PLEASE EXPLAIN * ThIS IS AN EXAMPLE I AM NOT CHEATING-21+49/7+1
First of all:
Pemdas stands for:
P- Paretheses
E-Exponents
M-Multiplication
D-Division
A-A
given the graph of a limacon with a loop, how do you find the area inside the large loop but outside the small loop?
for example, if r = 1-2sin(theta), how do you do that???-If you integrate from pi/6
Its been a while since I did this and I cant remember how to solve for y in terms of x.
Ex) 2x - 3y = 12
Ex) 5x + 2y = 7
I know simple stuff, but Im just completely blanking-move the x terms over to
When your front term has a coefficient you should look for a common factor, and then try factoring through grouping. In this case they all share a 2.
18x^2+24x-10
2(9x^2 + 12x - 5)
Now multiply the
help!! solve for x. i havent done algebra in 25 years! need for assesment test. thanks to anyone who can help-you cant get a real answer, but you can just get x.
you have to add 3y to the other side b
Im having a bit of a brain fart here, the problem is that I need to change this:
-2 / (1-i*sqrt(3))
into this:
(1-i*sqrt(3)) / -2
I know theres a basic maneuver to flip that division statement, b
lim as x approaches 9 of (√(x)-3)/(x-9)
Im really rusty with my math, and I know Im missing a step after multiplying by the conjugate....help?-√x -3-------- =...x-9
........√x - 3--------------------
the problem is 17/24 - 5/18 and to put it in lowest terms. First I got 26/72 and brought it down to 13/36. Is this the right answer? I put them both in LCD and subtracted only the numerator and left t
My intentions are to check my answer and get a explanation I am not trying to copy or cheat is this correct 5^3=125
is this correct3^6=729
is this correct 2^8=128
also I dont get this sorry its just
Use the numbers on the top to fill out the bottom.
1, 2, 3, 4, 5, 6
__ - __ + __ ( __ / __ ) - __ = 10
1, 2, 3, 4, 5, 6
__ ( __ / __ - __ + __ to the power of ) = 50-5-3+2(6/1)-4= 10
or
5-4+2(6/1
so 1500 will be written as 1.50x10^3 .....but since will move the decimal left three should the 3 not be negative ??? or is it only negative if it passes 1500 like when it is .1500 ??? or my question
I have missed 5 days of school and I have a sh*t load of homework. Im on my math now and am confused as to what they want. The instructions read: Solve each formula for the indicated variable.
1. A =
im stuck! please help!
Construct three different augmented matrices for linear systems whiles solution set is x1 = 3, x2 = -2, and x3 = -1
i would think to make a 1 matrice but it wants three? im st
Thank you very much and please show your steps.
I really appreciate any help!-Average value is:
[1 / (b-a)] ∫[x=a to b] f(x) dx
In your case, a = 0, b = 10π, and f(x) = cos²(x)
Then plug in it:
[1
Lets say I have a right triangle ABC. angle C=90*. side c=25, and side b=24. How do I find side a, and how do I find the measures of the other angles. And would it be possible to find the angles witho
