I know the limit as x goes to negative infinity is 0 and I thought it was 0 for positive infinity too, but its not. Can you point me in the right direction? Thanks!-A/(1+Be^(-kt))
?
1. In what interval(s) between 0 and 2pi are tan(theta) and sin(theta) both negative? Both positive?
2. Find all angle measures between 0 degrees and 360 degrees for which the sin of theta = -0.55
What is the smallest number of satellites that would be able to broadcast a signal from a single station on earth so that every party of the equator could receive a signal? provide an explanation as w
Okay so Im learning how to solve a problem from my math text and they show the steps on how to solve it, but already and Im getting stuck at Step 3. The problem was at first, from Step 2, 9 - (x^2)/4
Please help I have no clue on this.-f(x) is the right half of a parabola, with vertex (1, -1), opening up.
y = f(x) = (1/2)(x - 1)^2 - 1
x = (1/2)(y - 1)^2 - 1
x + 1 = (1/2)(y - 1)^2
2(x + 1) = (y -
Hello! I am having trouble with a math problem. Here is the detail:
A solid is enclosed by two cylinders z = x^2 and y = x^2 and two planes y = 4 and z = 0.
Find the volume of this solid.
I was usi
Right now I have the 2.43 version, which is also available on the TI website (which claims the 2.43 version is the new operation system), but I read that 2.55 is the newest operating system. Where can
If three vertices of a parallelogram in the plane are (-5,3), (5,2) and (7,-8), determine all the possible coordinates of the fourth vertex.
please help, thanks :)-In this case, there are actually 3
1)3x + 10
is it x
2) x/2 ≥ 5 + x/12-1. OK
2. Multiply all by 12:
12x/2 >= 5*12 + 12x/12
6x >= 60 + x
5x >= 60
x >= 12
Jen-first answer seems to be correct
second answer is x>=12
a. (-∞, -1]
b. (-1,∞)
c. [-1,∞)

3. Which is the solution set of -4 ≤ 3 - y over the whole num
ok so I have
(1,2,3) = a(2,2,2) + b(1,0,1)
I am trying to find out if (2,2,2) and (1,0,1) are linear combinations of (1,2,3). Cant remember though how to tell if it is or isnt. So I need to know if a
What is the domain of 4 sq root 3x+7-The domain is simply all numbers that do NOT: Make the denominator zero, or make the expression imaginary, or result in an error of some sort (i.e. ln(-1))
So wha
Checking my work is correct. Thank you-f(x) = (2x - 2)/(x + 3)
Let y = f(x)
=> y = (2x - 2)/(x + 3)
=> xy + 3y = 2x - 2
=> xy - 2x = -3y - 2
=> x = (3y + 2)/(2 - y)
replacing y with x
we get
inverse
quadratic equation sum-x = the number
3(4x) = x² + 20 {created the equation based on the first sentence}
12x = x² + 20 {multiplied 3 by 4x}
x² - 12x + 20 = 0 {subtracted 12x from both sides}
(x - 10)
