Answer:
Step-by-step explanation:
A sample of bacteria is decaying according to the half-life model f(t) = Ne -0.226t, where N is the initial sample size and t
is time in hours. At t = 4, there are 25 bacteria remaining. What was the initial sample amount? Round your answer to the
nearest whole number, and do not include units.

Answer:

Step-by-step explanation:
The parametric equations of a circle is
and 
The radius of the unit circle is 1 unit.
This implies that any point on the unit circle is represented by:
and 
where
is the angle in standard position,
From the question, the given angle in standard position is
.
This angle intersects the unit circle at 
But 
We substitute
and 
This implies that: 
9514 1404 393
Answer:
45°
Step-by-step explanation:
Arc YZ is the difference between the given arcs and 360°:
126° +144° +YZ = 360°
YZ = 360° -270° = 90°
The inscribed angle (?) is half the measure of the arc it intercepts:
? = 90°/2
? = 45°
