Answer:
D. 3*10^2
Step-by-step explanation:
Given the diameter of human red blood cell = 0.000009 m
diameter of a cold virus = 0.00000003 m
To know how many times as large is the diameter of a red blood cell as the diameter of a cold virus, we will take the ratio of the diameter of human red blood cell to that of a cold virus as shown;
diameter of human red blood cell/diameter of a cold virus = 0.000009 m/0.00000003 m
= 9*10^-6/3*10^-8
= 9/3 * 10^-6-(-8)
= 3 * 10^(-6+8)
= 3*10^2
Hence the diameter of a red blood cell is 3*10^2 larger than that of the cold virus
The opposite of 1/4 is -1/4 which is represented by "L" on the number line.
You are looking for several things when determining if a function is exponential or not.
An exponential function needs three things. A base, a power which is always a variable, and a constant.
Let me write a random exponential function and I’ll use it as an example.
f(x)=100x1.05^x
This is an exponential function because the c (constant) is 100. The c usually is about a population or object that is increasing.
The base is 1.05 which is usually a percentage increase.
Then the power which is x and this controls the time. It could be per day, year, and etc.
All of these factors contribute to the exponential function. If you have any questions ask, don’t be shy. :)
You run 26410.76 ft every day
Take a look at the horiz. line. It has arrows at both ends. That means that x goes on forever in both directions. Thus, the domain of this function is (-inf, +inf).
