Answer:52°
Step-by-step explanation:
x+x+14=90
Collect like terms
x+x=90-14
2x=76
Divide both sides by 2
2x/2=76/2
x=38
angle (x+14)°=(38+14)°=52° which is vertically opposite to angle PKQ.
Since Vertically opposite angles
Therefore angle PKQ=52

Answer: 380000 cells/hour
Step-by-step explanation:
Given that dP/dt = 0.19P(t)
where
P(t) is the size of the culture (measured in millions of cells) at time t > 0 (measured in hours).
The formula above represents a mathematical model for the growth of a certain cell culture. In essence, it represents the time rate of the growth of the cell culture, that is how fast the cell culture is growing.
Therefore, when P = 2 million cells:
dP/dt = 0.19 * 2000000 = 380000 cells/hour
Hence, the cell culture is growing at 380000 cells per hour.
Final answer:
The cell culture is growing at a rate of 0.38 million cells per hour when the size of the culture reaches 2 million cells. This is based on the given differential equation dP/dt = 0.19P(t).
Explanation:
This problem is associated with the concept of differential equations, particularly exponential growth. In this scenario, the rate of change of P(t), the size of the cell culture, is given by the equation dP/dt = 0.19P(t). This can be interpreted as the culture is growing at 19% per unit of time.
To determine how fast the culture is growing when P(t) equals 2 million cells, we need to substitute 2 for P(t) in the given equation: dP/dt = 0.19*2. This calculation returns a value of 0.38 million cells per hour. Therefore, when the size of the culture reaches 2 million cells, it is growing at a rate of 0.38 million cells per hour.

Answers
Answer:
How do you derive the equation of a circle?
you can reverse the circle formula
How do you identify the center and radius of a circle?
You can identify the center because it is the middle of the circle and the radius can be draw from the center to the round part.
How do you define the radian measure of an angle?
it is the ratio of the length of the arc the angle forms÷the radius of the circle
How are arc length and area of a sector related to proportionality?
sector x radian
area = (r^2 x)/2
arc length = r x
they are not propotional
because Area / arc length = r/2 , (it's not a constant)
