3) .724160441-he did thousandths^^^^
1) 1.8917
2) -2.8074
3) .7242-1) 1.892
2) -2.807
Find an equation of the line tangent to f(x)=3x^3-5x at x=2.
Thank you very much!-Determine the point by substituting x with 2 for f(x):
f(2) = 3(2)³ - 5(2)
= 3(8) - 10
= 24 - 10
= 14
The point is

any 1 cn solve dis?????????? if
3+18=7, 9-3+1
7+14=3,
6+18=4,
8+112=15,
9+135=?-its answer is 16..
in this ques..we divide 3 and 18 we got 6 ..6+1 = 7
similarly7 and 14 we got 2 ..2+1 = 36 and 18
Hi, Im having trouble with the following question and would appreciate some help.
∫ 1/(x^2·sqrt(4 - x^2)) dx
My attempt is this:
let u = sqrt(4 - x^2), x^2 = 4 - u^2, u = -x/u = sqrt(4 - u^2)/u;
=
How do I integrate (e^x)*(sinx)^2 ??
I know I need integration by parts.
If I choose e^x as my u i get
e^x (sinx)^2 - integral of e^x 2sin(x)cos(x) dx
and I dont know how to solve that integral eith
Hey guys, I have been killing some of the neurons I got left trying to solve these 2 problems..
Find the coordinates of the vertex and the axis of symmetry of the graph of the equation. If necessary
i think its 1, my friend thinks its 9.
so whats the answer ?-it is 9
first you perform the parenthetical equation (1+2)
6÷2(3)
then the 6/2 because there is no parenthesis around 2(1+2)
3(3)
lastly yo
I am generally very good in math, and it is one of my favorite subjects, but the problem is that I am kinda slow. It wasnt a big problem before, but it is a slight problem now. I had a chemistry test

ok, so here is my question:
find the y-mx+b form of a line passing through points (3, -1) if:
a)the x intercept is (-1, 0)
i know if there is an x-intercept the y value is always 0, but i have to so
assume that a normal distribution of data has a mean of 10 and a standard deviation of 2. use the 68-95-99.7 rule to find the percentage of values that lie above 12.
I really dont understand. I know
