PS :
I am trying to model some data using the quadratic function
I am aware of the following points on my graph...
x-intercept(s) = -22.5 and +67.5
The vertex = (+22.5, +48)
Using the knowledge of these
Hello
find theta, where theta = r:
r = 3 - 2sin(r)
solutions: theta1 = 1,16
theta2 = 3,28
theta 3 = 4,94
--------
r = 3 - 2sin(Θ)
r = - 2cos(Θ)--> plug into equation for y: y is the slope for any
INtegral of (cotx)/((sinx)^(1/2))
please solve it
Shoe Working-cotx/sinx^1/2=cosx/(sinx)^(3/2)
let sinx=t
cosx=dt
it becomes
dt/(t)^(3/2)= -2(t)^(-1/2)
=-2(sinx)^(-1/2)-First, notice that cot x is j
i know the answerse to all of these, the only problem is how to attain it?
1.Find the critical value zα/2 that corresponds to a 98% confidence level.answer:2.33
2.Use the given degree of confidence
The multiple choices on the quiz included: a.2 b.-2 c.-4 d.1/2 but none of these work!!! Im so confused!!!!!!!!!!!!!!!!!--16n^2 - 64n + 64 = 0
-16(n^2 + 4n - 4) = 0
n^2 + 4n - 4 = 0
you cant factor
At the school play on Friday night, 120 tickets were sold. Student tickets cost $5 each and Adult tickets cost $7 each. The total sales for the evening were $670. How many of each type of ticket were
So I need to integrate x(Sqrt[13-x^2]
I understand that the answer is -1/3 (13-x^2)^3/2
I just dont understand the steps involved to solve it.-∫ [x][sqrt(13 - x^2)] dx
Let u = 13 - x^2
du = -2x dx
What does it called when you divide 1 by infinity?
(1/(symbol of infinity))
Do they have name for this?-A related idea is indeterminate form.
I think in most systems that have a 1, an infinity, and
(i) Murphy’s law states that anything that can go wrong will go wrong. The following table lists the joint probabilities of getting a flat tyre while riding your bicycle to work and whether you have a
Hi, I dont understand how to do this problem. I am having a test soon an this so I need to understand how to do it, please show you work or how you did it.
1.The numbers 2, 4, 6, and 8 are a set of f
Convert the point from polar to rectangular form:
(√3, π/6)-r = √3
θ = π/6
x = r cos(θ) = √3cos(π/6)
x = √3(√3/2) = 3/2
y =r sin(θ) =√3sin(π/6)
y = (1/2)√3
(x, y) = (3/2,√3 /2)-1.5, .86
I read an article about a new drug which stated that the incidence of side effects was similar to placebo, P-value > 0.05. I want to know if the results are significant at α = 10%. With the informatio
