Answer:
Step-by-step explanation:
is an exponential equation where A is the beginning amount and B is the rate that the population grows or dies.
So we start with 1000 bacteria, they are giving us A.
The bacteria population is decreasing because they are dying 5% each hour.
So that is after the first hour we have 1000-.05(1000) or 1000(1)-1000(.05)=1000(1-.05)=1000(.95).
We will keep multiplying by .95 per hour. 0.95 is the repeated factor.
That is the function is .
If you let h=0 which means 0 hours has happened, you will see the bacteria is 1000 as desired. 1000(.95)^0=1000(1)=1000.
Answer:
Option 4
Step-by-step explanation:
The line passes through the origin, and thus has a y-intercept of 0.
The line also has negative slope.
- Eliminate Options 2 and 5.
We can calculate.the slope of the line to be:
making the answer Option 4.
Answer:
D. 63 degrees
Explanation:
We can use the Trigonometric ratio ‘Tan’ to get angle B (because you have all 3 lengths, you can use any ratio. I used tan because it didn’t make use of the decimal number).
TanB = opposite/adjacent
TanB = 4/2
TanB = 2
B = Tan^-1(2)
B = 63.43°
Your answer is D.
Please feel free to comment if you do not understand the use of ‘Tan^-1’
