Can someone provide a step-by-step solution? Thanks!-y = (x^2)e^-x
y = (-e^-x)(x^2) + (2x)(e^-x) (product rule)
y = e^-x(-(x^2) + 2x)
when x = 1,
y = e^(-1)(-1 + 2)
y = 1/e
Now, to find a tangent li
Very confused, it says to simplify answer & express complex numbers in terms of i.-This is a quadratic equation, soyou want to use the Quadratic Formula.
3x^2 - 7x = -6
3x^2 - 7x + 6 = 0
a = 3, b =
Or in words it would be ten to the four x power minus five equals eleven. I really need the answer!-10^4x-5=11
10^4x=16 take the -5 to the other side
log(10^4x )=log(16) take logs
4x(log10) = log(16)
heres a numerical order:
2, 7, 18, 28, 18, 28, __

The radius of a circle is increasing.At a certain instant, the rate of increase in the area of the circle is numerically equal to twice the rate of increase in its circumference.What is the radius of
Okay I am confused and suck at math so I need help.
Using a graphing calulator find the equivalent rectangular equation.
x=1/2t,y=6t-3;-1
xmin = -10
xmax = 10
ymin = -100
y max = 100

i did the math a bunch of times but kept getting 13, 14, or 15. idk which one. ! :( ugh, lol yea i know i should know my own age...sorry :( thanks-Over 9,000.-15-Old enough to know how old you are....

find the domain.x^2-5x+6/3x^2-2x-8
how do I solve this!! Looking for best answer!-Any number divided by zero gives you an undefined value, so this problems domain cannot include the roots of the botto
Find infinitely many polynomials f(x) in Z3[x] such that f(a)=0 for all a in Z3-The polynomial x (x - 1) (x - 2) = x (x^2 - 3x + 2) = x^3 - 3x^2 + 2x certainly has this property.
And since -3 = 0 in
hi !! :) thank you so much in advance !! :) i am revising for my standard grade maths came across these and my mind went blank !! panicking now !!
i have a diagram and it says find the minimum turnin
This is my third question on volume of cone already. Yikes. Im really not getting this.
Heres the image of the problem/solid once again:

x=2n+)pi/2-The cosine of an angle x is 0 at the following angles:
π/2, 3π/2, 5π/2,...
So, from this you can see that the general solution is
x = (2n + 1)π / 2
Where n is an integer.-x=90
