1. tanA = 12 / 25 = 26.
2. radius = 38.4 / 2 = 19.2.
14.7^2 + b^2 = 19.2^2 => b = 12.4, by pythagorean theorem.
Finally, x = 19.2 - 12.4 = 6.8.
The exponential function is often used to model the growth or decay of a population
The population size of the yeast cell after 3 hours is 6.24 million
The given parameters are:
a = 3.1M --- initial number of cells
r = 0.4425 per hour --- rate
The nth term of an exponential function is:
f(n) = a(1+r)^n-1
After 3 hours; n = 3
So, we have:
f(3) = a(1+r)^3-1
Substitute values for a and r
f(3) = 3.1 (1+0.4425)^3-1
f(3) = 3.1 ( 1.4425)^2
f(3) = 6.24
Hence, the population size of the yeast cell after 3 hours is 6.24 million.

Step-by-step explanation:
Answer:
698.5
Step-by-step explanation:
Time-and-a-half. Time-and-a-half is payment to a worker (or workers) at 1.5 times their usual hourly rate.
11×1.5=16.5 $ per hour
16.5 ×7 =115.5 $ - total for overtime
11×2 = 22$ per hour
22×6.5= 143$ - total for double time payment
440+143+115.5 = 698.5 $ - total earnings
