Answer:
D im pretty sure :) hope this helps
Step-by-step explanation:
let's recall that the sum of all interior angles in a triangle is 180°.
an equi-lateral, equal sides, triangle has all sides that are equal.
sides that are equal will yield an equal opposite angle.
so if all sides are equal, all angles are equal, for a sum of 180°, that's only possible with 60°, 60° and 60° angles, and all of them are acute, none obtuse.
Answer:
Option (D).
Step-by-step explanation:
Initial population of the deer
= 4800
Decrease in the population of the deer after every 8 years = 
Decrease in population is an exponential process, so the expression representing population will be,

Where
is the population after 'x' slots of 8 years.
r = fraction of decrease in the population
x = 
By substituting the values of r and x in the expression,


Therefore, Sylvia should do few corrections in her expression.
(8) should be replaced by (
) and
should be replaced by
.
Option D. will be the answer.
