Hi, thank you for posting your question here at Brainly.
Simply substitute the value of the intensity to the variable i. Taking its logarithm to the base 10, the answer would be 7.8. Hence, 6 million ergs is equivalent to 7.8 based on the Richter scale.
Answer: f(x) = x/2 + 4.
where f(x) is the number of stamps that Tom has, and x is the number of stamps that Myrna has.
Step-by-step explanation:
The statement is:
"Tom has four more than half the stamps that Myrna has"
For how is written, we can model the number of stamps that Tom has as a function f(x).
f(x) represents the number of stamps that Tom has, and x is the number of stamps that Myrna has.
Then:
"four more than a number" is written as:
N + 4 (where N is the number)
"Half the stamps that Myrna has" is written as:
x/2.
Then the whole statement can be modeled as:
f(x) = x/2 + 4.
notice that we have x/2, and f(x) must be a whole number, so Myrna must have an even number of stamps (in that case x/2 will be integer)
X=-0.61 and Y is 4 is I did my math right
It's D if I am correct, I'm unsure though.
