The functions in part A are correct, we will now use them to solve for part B.
We equate the numbers of the trees in order to find x, which the number of years after which they will be equal.
800(0.95)ˣ = 50(1.15)ˣ
40 = (1.15 / .95)ˣ
Taking log₁₀ on both sides,
log(40) = x*log(1.15/0.95)
x = 19.31 years
Answer:
4
Step-by-step explanation:
5 smiles - 1 = 4 smiles
To find the gradient you do change in y/change in x so...
-12 - 0
————- = -12/4 = -3
0 - - 4
Hope this helps! Any questions let me know :)
While “digital” commonly refers to electronics in general, the scientific definition of digital is much different. “Digital” in information science refers to the finite, discontinuous phenomenon (e.g., on or off states in a light bulb) as opposed to infinitely varying, continuous analog phenomenon (e.g., the brightness of daylight). It can also refer to representing data in figures as opposed to data represented in pictorial form.
