Answer:
It takes 7.37 hours for the size of the sample to double.
Step-by-step explanation:
Continuous exponential growth model:
The continuous exponential growth model for populations is given by:
In which P(0) is the initial population and r is the growth rate parameter, as a decimal.
Growth rate parameter of 9.4% per hour.
This means that 
So
How many hours does it take for the size of the sample to double?
This is t for which P(t) = 2P(0). So
It takes 7.37 hours for the size of the sample to double.
Answer:
x = 97.5 degrees
Step-by-step explanation:
First, we need to know what the total sum of interior angles. We use the formula (n-2) * 180, n being the number of sides.
Since this is a 6-sided polygon, the sum is (6-2) * 180, or 720 degrees.
We have the total sum of interior angles, so now we have all the information we need.
720 degrees = (2x-50) + (x+40) + 80 + (x+20) + 90(right angle symbol) + 150
720 = 4x + 330 (subtract 330 from both sides)
390 = 4x (divide by 4)
x = 97.5 degrees
step by step explanation:
=[x2+16=0x26]
=[2x{y}^2{16}~0]
=[4×{y}^0{16}]
=[32x{y}^x]
This is an easy way to solve multiplication with alot of zero's
Add only the numbers, then add the sum of the zeros
So with this problem we do this:-
5*4 is 20, plus the zero in the 50, so the answer is 200
Now we can do the other one:-
5*4 is 20, plus the 4 zeros that we removed is 200,000
Hope I helped. :)
Answer:
y = 
x - 
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
here m = , thus
y = x + c ← is the partial equation
to find c substitute (2, - 4) into the partial equation
- 4 = 
+ c ⇒ c = - 4 - = -
y = x - ← equation of line
