Answer:
800 minutes
Step-by-step explanation:
Make 2 expressions, one for Plan A, and one for Plan B
Plan A:
$9, and 0.17 per minute
9+0.17x
Plan B:
$25, and 0.15 per minute
25+0.15x
We want to find when they are the same, so we can set them equal to each other
9+0.17x=25+0.15x
Solve by isolating the variable, x
Subtract 9 from both sides
0.17x=16+0.15x
Subtract 0.15x from both sides
0.02x=16
Divide both sides by 0.02
x=800
At 800 minutes they will cost the same

Step-by-step explanation:
Hello, we cannot see the ellipse equations.
The eccentric of an ellipse is given by:
Assuming the equations are:
Then a²=25 and b²=16
The eccentricity is:
If the ellipse has equation,
then the this time, we have a=5 and b=3.
This means that:
(a) ln(3)/30 = 0.0366
_____
The solution to the differential equation is
.. p(t) = p0*e^(0.0366t)
then
.. p(30) = p0*e^1.098 = 3.00*p0 . . . . to 3 significant figures
Answer:
it will be (0,9)
