Answer:
x ≈ 3.7 m
Step-by-step explanation:
Use the right triangle on the left to find the height h , using the sine ratio
sin39° = =
( multiply both sides by 7 )
7 × sin39° = h , then
h = 4.4
Using the tangent ration on the right side right triangle, then
tan50° = =
=
( multiply both sides by x )
x × tan50° = 4.4 ( divide both sides by tan50° )
x = ≈ 3.7 m ( to 1 dec. place )
<em>There is no specific requirement in the question, but I'm assuming you need to compute the time needed for Alexis reach 1,000,000 Instagram followers</em>
Answer:
Step-by-step explanation:
<u>Exponential Growth </u>
When the number of observed elements grows as the previous value multiplied by a constant ratio, we have exponential growth. The formula to model such situations is
Where is the initial value of f, 1 + r is the constant ratio, and t is the time expressed in half days (12 hours)
The initial value is 100 Instant followers, thus:
We need to know when the number of followers will reach 1,000,000. Setting up the equation
Simplifying by 100
Taking logarithms
Solving for t
periods of 12 hrs
