Okay, having a bit of trouble with this question:
Eliminate the parameter t from the following parametric equations to find a cartesian equation of the curve they represent.
x = 5cos(6t)
y = 3sin(6
We never did any of this in class and I cant find anything on Google about how to do it...
A study was conducted to compare the average time spent in the lab each week versus course grade forcomputer
The half life of strontium 90 is 28 years. Suppose we have a 76 mg sample.
a)find a function that models the mass m(t) remaining after t years.
b)how much of the sample will remain after 70 years?-
I know that certain equation cause a transformation (ie, y=f(x-2)) and I wasnt sure how absolute values affect the original function. Im given y=f(x), which is a curve with points at (-2,1), (-1, .75)
Ok, for example: if I wanted to turn $1000 into $8000 over a period of 12 months. What is the account growth percentage per month needed to reach $8000. Ive tried (8000/1000) / 12, the answer is 67%.
-10x^2-4x+18-See, the equation is of a parabola which will open downwards.
differentiating w.r.t. x , we get the maximum value of y:
dy/dx=0=-20x-4
x=-1/5
y=-10x^2-4x+18=18.4
hence, range =(-infinity

i dont think you can go anywhere else.-Several answers are wrong because division comes first by default.
This is an algebraic expression, that is all you asked for.-I guess you could factor out a 3
