Answer:
The polar coordinates of point P are and
.
Step-by-step explanation:
The given point is
If a point is defined as P(r,θ), then all polar coordinates are
Where, θ is in radian and n is an integer.
The polar coordinates of point P are
Therefore the polar coordinates of point P are and
.

Leslie is a biologist. She is going to randomly select one animal from her lab to study. There are 5 salamanders, 3 crayfish, and 12 minnows in her lab. What is P{salamanders}.
Answer:
0.25 or 25%
Step-by-step explanation:
Since there are number of salamanders = 5
number of crayfish = 3
number of minnows = 12
total number of animals n = 5 + 3 + 12 = 20
She wants to randomly select an animal and check if it is Salamander or not.
=
=
= 0.25 or 25%
Answer:
Step-by-step explanation:
It looks like you're asked to find the value of y(-1) given its implicit derivative,
and with initial condition y(2) = -1.
The differential equation is separable:
Integrate both sides:
Solve for y :
Use the initial condition to solve for C :
Then the particular solution to the differential equation is
and so
