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
(f/g)(8)=f(8)/g(8)
find f(8) and g(8) to mke it easier
f(8)=3-(8)=3-2(8)=3-16=-13
g(8)=1/(5+8)=1/13
so (f/g)(8)=-13/(1/13)=-13*13=-169
answer is -169
The TOA part of SOH CAH TOA tells you ...
Tangent = Opposite/Adjacent
When applied to the triangle of shadow and person, this means
tan(24°) = (1.82 m)/(shadow length)
This can be rearranged to
(shadow length) = (1.82 m)/tan(24°) ≈ 4.09 m
