Im trying to remember how to do integration by parts and I cant seem to figure out where LIATES comes into play. I know what it stands for but when do you use it? Does it help you pick what to use for
Find the values of a, b, and c that satisfy the equation; 3ax^2 + bx + 5x + c - 7 = 12x^2 - 6x - 9
I need a mathematical and/or literal explanation for proof of the correct answers.Note that there ar
A pet store sells nylon tunnels for dog agility courses. If a tunnel is 6 feet long and 1.5 feet in diameter, how much nylon is used to make it?-Since fabric is generally measured in square yards,
6*1
In words it is log base ten of 3x equals log base ten of two plus log base ten of x + 5.-log 3x = log 2 + log (x+5)log (x+5) = log 3x - log 2 = log(3x/2)
(x+5) = (3x/2)
2x +10=3x
x = 10-If you have lo
What percent of Richs game did he score at least 180?? He scored 6... But how much is that in percent... its not 60%.
These are the choices are
10%
20%
25%
15%-where is the total?
you are supposed to
so i thought you would use the F.O.I.L. method (multiply x by a and -5 and then multiply 3 by x and -5)
but on the paper (someone elses im borrowing for practice) he circled the answer: x squared - 15
tan x = sqrt(3) - sec x
Square both sides
tan^2 x = 3 - 2sqrt(3) sec x + sec^2 x
sec^2 x - 1 =3 - 2sqrt(3) sec x + sec^2 x
sec x = 2/sqrt(3)
cos x = sqrt(3)/2
x = pi/6, 11pi6(rejected after checking)
Can you please explain to me how I can solve this? im seriously lost
thanks--√-81
-√((-1)(81))
-(i)(+ or - 9)
Final answers are: 9i or -9i-Express in terms of i -√-81?
i -√-81 = i - 9i = -8i >=======
:-) The starting point is with simple equation systems (the ones that look like y = mx + b) which are graphically linear.
As you progress, you move into matrices, which are effectively sets of vector
