Answer:
Step-by-step explanation:
So an angle has two parts. Initial side and terminal side.
Inital side like on x axis. and terminal side shows how much it open up. Here the terminal angle terminates in second quadrant so we have the following
- A negative Cosine Value
- A positive Sine value
- A negative Tangent Value.
Now, using Pythagoras identity let solve for cos theta.
Here you on the right track but remeber that son theta=1/3 so sin theta squared would be 1/3 squared so we have
Note since cosine is negative in second quadrant, cos theta is
To find tan theta we do the following
So
Tan is negative in second quadrant
Answer:
1 year
Step-by-step explanation:
The population can be modelled by the equation:
From the question, the initial population is
The annual growth rate is r=0.04
We want to find how long it will take for that population to reach 43500.
We substitute the values to get:
To the nearest year, t= year
Answer:
C.
Step-by-step explanation:
Decay is getting smaller, and c is the only one where B will reduce the size of something.
Answer:I'm guessing the average mass of the two apples each is 35 grams
hope this helps I didn't really understand the quetsion
Formula for area:
Area=pi x r^2
=pi x (100 / 2)^2
=pi x 50^2
=7853.98
