The tangent of a given circle is perpendicular to the radius a the point called point if tangency. The radius of the circle is perpendicular to the tangent at the point of tangency. This property is especially useful in cases where the radius that connects to the point of tangency forms a part of right angle because the pythagorean theorem and trigonometry apply to right angles.
Answer:
8 Shampoo Concentrate
Step-by-step explanation:
There's a ratio of 9:2 so for every 9 cups of water there's two cups of shampoo concrete.
We'll need 9 multiplied by 4 is 36
so we need to multiply 2 with 4
4 multiplied by 2 is 8
Answer:
a. The population does not become extinct in finite time.
Step-by-step explanation:
The model for the population of the fishery is

If we rearrange and replace the constants we have:

Now we can calculate if the population become 0 in any finite time

To be a finite time, t>0

We can conclude that the only finite time in which P=0 is when the initial population is 0.
Because P0 is a positive constant, we can say that the population does not become extint in finite time.
