6.32 in.
Step-by-step explanation:
2.92 + 3.4 = 6.32
The range of communication is about 55 meters.
Answer:
This is one possibility fitting the criteria.
Step-by-step explanation:
I was thinking about using the sine curve because we have that it starts at and not . The factor of 5 came from the amplitude.
So we know so far our function looks like this .
However the inside will be effected since the period is 2.
has a period of .
has a period of .
We want to have a period of 2 so we want to solve .
So multiply both sides by b:
Divide both sides by 2:
.
So the function we have from the given information is:
Step-by-step explanation:
5ˣ⁻² = 6
Take log of both sides.
log 5ˣ⁻² = log 6
Use log exponent property.
(x − 2) log 5 = log 6
Solve for x.
x − 2 = log 6 / log 5
x = 2 + (log 6 / log 5)
x = 3.1133
