Please explain how you got the answer in detail.
I dont understand how to do it. ):-∫ √x(2 + x) dx
= ∫ (2√x + x√x) dx
= ∫ (2x^1/2 + x^3/2) dx
= {(2x^(3/2)) / (3/2)} + {(x^(5/2)) / (5/2)} + C
= (4/
Solve this system of equations:
(x-2)^2 + (y+1)^2 = 10
y=x-1-Substitute y=x-1 into (x-2)^2 + (y+1)^2 = 10
to get (x-2)^2 + (x-1+1)^2 = 10
(x-2)^2 + (x)^2 = 10
Multiply out to get
x^2 - 4x + 4 + x^2 =
The mean score is 290 with a standard deviation 20.-Id really like to know how to do this myself.I just solved it in Excel the really really long way, the answer is 97.7%.
9(1-x)^2 is equivalent to 9(1-x)(1-x)
Start with the 1 in the first expression and multiply that by (1-X), so you have 1-X
Then multiply out the -X by the (1-X), so you have -X+X^2 (it becomes positi
Use the equation of the exponential function whose graph passes through the points (0,-2) and (2,-50) to find the value of y when x=-2

Five forces act on an object: (1) 60.0 N at 90°, (2) 40 N at 0°, (3) 80 N at 270°, (4) 40N at 180°, (5) 50 N at 60°. What are the magnitude and direction of a sixth force that would produce equilibriu
f(x)=x^2+2
find f(3)??-3^2+2= 9+2=
11-f(3) means you should substitute 3 in for the x in the equation:
f(3) = (3)^2 + 2 = 9 + 2 = 11-f(x) = x^2 + 2
substitute 3 in for x and we get
f(3) = 3^2 + 2
I need help with this problem.Homework
Thank u in advance-This is not clear.
if you write it as (8-5)! then it is 3!, which is 3*2*1 is 6.
or we can think as in your one 8 - 5! this is equalto 8 - 5
So, I was thinking this..
im going to 8 grade and I have the choice whether going to Pre Algebra or Algebra 1
but if you go to Algebra 1 you need to know the basics and I dont know any
so, should I sk
Is my answer correct??
Question:
Determine the area under the standard normal curve that lies between -2.5 and -2.
My solution is:
Z(1)= -2.5; therefore, the Area (1)= 1.1162
Z(2)= -2; therefore,
Ive never had a teacher whos explained the rationale behind the quadratic formula.I tried to work backwards to figure out (its kind of hard to read in this format):
x=(-b+/-sqrt(b^2-4ac))/2a
2ax=-b+/

Note that, from the unit circle, sin(x) = 1/2 when x = π/6 ± 2πk and x = 5π/6 ± 2πk where k is an integer.
Thus:
sin(ax) = 1/2
==> ax = π/6 ± 2πk and ax = 5π/6 ± 2πk
==> ax = π(12k ± 1)/6 and ax = π
